each CPU processes its individual user program independently of the other
CPUs (multicomputing).
The following are available as CPUs:
CPU 948 For fast word and binary signal processing especially
fast double-word and floating point processing and for
large programs with a high storage requirement.
Programming in STEP 5.
When you use a CPU 948 you have an S5-155U PLC.
CPU 928B For fast word and binary signal processing and for
communication. Programming in STEP 5.
CPU 928 For fast binary signal processing and for word
processing. Programming in STEP 5.
CPU 922
(R processor) For word processing (computing controlling
monitoring signaling). Programming in STEP 5.
You can combine the CPUs arbitrarily at the CPU slots in the central
controller:

Pointers on how this manual is organized are given as a guide below. They
will assist you when using your S5-135U/155U programmable controller.
At the start of this manual you will find the “Safety-Related Guidelines”
and the “ESD Guidelines.” You must observe these to the letter and
follow them during the entire time you are working with the
S5-135U/155U PLC. If your PLC requires repair, you must observe the
Repair Guidelines in Section 4.1.4.
Chapter 3 contains the Installation Guidelines with information on
interference-free installation of the S5-135U/155U PLC.
Which of the remaining chapters of this manual you may require when
working with your PLC will depend on the extent of your automation task
and on the configuration of your PLC.
For a basic configuration in single-processor operation without expansion
units, you will need the following chapters:
Chapter 4 describes the central controller (CC) in Section 4.1. The
technical features, installation, startup and maintenance of the CC are
described here. Section 4.3 describes the power supply units. You will
find a separate description of the 6ES5 955-3NA12 power supply unit in
Section 4.5. Both sections describe the installation and startup as well as
the necessary maintenance on the power supply units. The 24 V/4 A load
power supply is described in Section 4.4.
Chapter 5 contains the instructions for the individual CPUs. The
technical features, installation and startup of the individual CPUs are
described here. The various methods of operating the CPUs are also
described, as are the CPU statuses where they can be directly indicated by
the LEDs on the module. If you use memory submodules or memory
cards (CPU 948), you can look up the necessary information in
Sections 5.7 to 5.9.
Chapter 8 and Chapter 9 describe the digital and analog I/O modules.
The installation, wiring and operation of these modules are described
here. Individual I/O modules exhibit specific features which are discussed
in separate chapters.
To configure your PLC with expansion units (EUs) you will need the
following chapters:
Chapter 2 shows how you can configure a PLC with expansion units in a
centralized or distributed arrangement.
Chapter 4, Section 4.2, describes the EU 183U, EU 184U, EU 185U and
EU 187U. Those EUs which operate with their own power supply unit are
described in Section 4.3.
Chapter 7 describes the interface modules (IMs) which serve for data
communication between central controllers and expansion units.
To operate two or more CPUs in multiprocessor mode in your PLC, you will
need Chapter 6.
Chapter 6 describes multiprocessor operation. This chapter contains all
the measures you must take for startup of the PLC in multiprocessor

Notes for Machine Manufacturers
The SIMATIC programmable controller is not a machine in the sense of the
EC Directive on machines. Therefore, there is no declaration of conformity
for SIMATIC as regards the EC Directive 89/392/EEC on machines.
The EC Directive 89/392/EEC on machines controls machine requirements.
Here, a machine is understood to be the entire sum of devices or parts
involved (see also EN 292-1, paragraph 3.1).
SIMATIC is part of the electrical equipment for a machine and must
therefore be included in the procedure for checking conformity by the
machine manufacturer.
The EN 60204-1 standard (machine safety, general requirements for the
electrical equipment for machines) applies to the electrical equipment for
machines.
The following table should help you with the declaration of conformity and
shows which criteria apply to EN 60204-1 (as at June 1993) for SIMATIC.

Safety Notes
Risks Involved in the Use of So-Called SIMATIC-Compatible Modules of
Non-Siemens Manufacture
“The manufacturer of a product (SIMATIC in this case) is under the general
obligation to give warning of possible risks attached to his product. This
obligation has been extended in recent court rulings to include parts supplied
by other vendors. Accordingly, the manufacturer is obliged to observe and
recognize such hazards as may arise when a product is combined with
products of other manufacture.
For this reason, we feel obliged to warn our customers who use SIMATIC
products not to install so-called SIMATIC-compatible modules of other
manufacture in the form of replacement or add-on modules in SIMATIC
systems.
Our products undergo a strict quality assurance procedure. We have no
knowledge as to whether outside manufacturers of so-called
SIMATIC-compatible modules have any quality assurance at all or one that is
nearly equivalent to ours. These so-called SIMATIC-compatible modules are
not marketed in agreement with Siemens; we have never recommended the
use of so-called SIMATIC-compatible modules of other manufacture. The
advertising of these other manufacturers for so-called SIMATIC-compatible
modules wrongly creates the impression that the subject advertised in
periodicals, catalogs, or at exhibitions had been agreed with us. Where
so-called SIMATIC-compatible modules of non-Siemens manufacture are
combined with our SIMATIC automation systems, we have a case of our
product being used contrary to recommendations. Because of the variety of
applications of our SIMATIC automation systems and the large number of
these products marketed worldwide, we cannot give a concrete description
specifically analyzing the hazards created by these so-called
SIMATIC-compatible modules. It is beyond the manufacturer’s capabilities
to have all these so-called SIMATIC-compatible modules checked for their
effect on our SIMATIC products. If the use of so-called SIMATIC-compatible
modules leads to defects in a SIMATIC automation system, no warranty for
such systems will be given by Siemens.
In the event of product liability damage due to the use of so-called
SIMATIC-compatible modules, Siemens are not liable since we took timely
action in warning users of the potential hazards involved in so-called
SIMATIC-compatible modules.”

Centralized and Distributed Configuration
of a Programmable Controller
This chapter contains an overview of the methods of configuring an
S5-135U/155U PLC. You will find a description of the types of
communication between a central controller and the expansion units, and an
overview of the interface modules required for the different types of
communication.

2.1 Application
The S5-135U/155U programmable controllers comprise a central controller
(CC) and, if required, one or more expansion units (EUs). You need EUs
when there are insufficient slots in the CC for the modules to be used.
Various interface modules (IMs) are available for communication between
the CC and the EUs and between the EUs. It is therefore possible to install an
EU or EUs in the immediate vicinity of the CC (centralized configuration) or
at some distance (distributed configuration). A combination of both types of
configuration is also possible by connecting additional EUs in a centralized
configuration with a distributed EU (see Figure 2-5).
This is clarified on the following pages.

3.1 Principles of Installation of Systems for EMC
Electromagnetic compatibility (EMC) is understood to mean the capability of
electrical equipment to operate correctly in a defined electromagnetic
environment, without being affected by the environment and without
affecting the environment to an unacceptable degree.
All SIMATIC S5 products have been developed for applications in harsh
industrial environments and meet high requirements for EMC. Before
installing the control system, however, you should still carry out EMC
planning and involve possible interference sources in the assessment.
The following chapter describes
The various paths over which interference can be picked up in the PLC,
Typical interference sources and their coupling mechanisms,
Basic rules for ensuring EMC.
3.1.1 Overview of Possible Types of Interference
Electromagnetic interference can be picked up over different paths by the
programmable controller:

Depending on the propagation medium (conducted or non-conducted
interference) and distance from the source, interference can be picked up by
the programmable controller via different coupling mechanisms.
A distinction is made between the following:
Direct coupling
Capacitive coupling
Inductive coupling
Radiated interference

3.1.2 The Most Important Basic Rules for Ensuring EMC
It is often sufficient to comply with a few elementary rules for ensuring
EMC. When installing the control system, therefore, observe the following
five basic rules.
When installing the programmable controllers, provide large-area good
quality grounding of the inactive metal parts (see Section 3.2).
Make a large-area low-impedance interconnection of all inactive metal
parts.
For screw connections on painted and anodized metal parts, either use
special contact washers or remove the insulating protective layers.
If possible, do not use aluminum parts. Aluminum oxidizes easily and is
therefore less suitable for grounding.
Make a central connection between the chassis ground and the
ground/protective ground conductor system.
Ensure proper routing of lines when wiring (see Sections 3.3.1 and 3.3.2).
Arrange the cabling in line groups. (AC power cable, power supply lines,
signal lines, data lines)
Always install AC power cables and signal or data lines in separate ducts
or bunches.
Route the signal and data lines as closely as possible to grounded surfaces
such as cabinet elements, metal bars and cabinet panels.
Ensure that cable shields are properly secured (see Section 3.3.3).
Data lines must be shielded. The shield should be connected at both ends.
Analog lines must be shielded. For the transfer of signals with low
amplitudes, it may be advisable to connect the shield at only one end.
Provide the line shields with a large-area connection to a shield/protective
conductor bar immediately after the cabinet inlet, and secure the shields
with cable clamps. Route the grounded shield as far as the module
without interruption, but do not connect the shield there again.
Ensure that the shield/protective ground bar has a low-impedance
connection to the cabinet.
Use metal or metallized connector cases for shielded data lines.

Employ special EMC measures for particular applications (see
Section 3.3.4).
Fit quenching elements to all inductances which are not controlled by
SIMATIC S5 modules.
Use incandescent bulbs for illuminating cabinets, and avoid fluorescent
lamps.
Create a standard reference potential; ground all electrical apparatus if
possible (see Sections 3.4 and 3.5).
Use specific grounding measures. Grounding of the control system is a
protective and functional measure.
System parts and cabinets with central controllers and expansion units
should be connected to the ground/protective conductor system in star
configuration. This serves to avoid the creation of ground loops.
In the case of potential differences between system parts and cabinets,
install equipotential bonding conductors of sufficient rating.

3.2 Installation of Programmable Controllers for EMC
Measures for suppressing interference voltages are often applied only when
the control system is already operational and proper reception of a useful
signal is impaired. The reason for such interference is usually inadequate
reference potentials caused by mistakes in equipment assembly. The
following sections describe:
Basic rules for grounding the inactive metal parts
Examples of cabinet assembly for EMC
Example of rack and wall mounting for EMC
3.2.1 Basic Rules for Assembling and Grounding the Inactive Metal
Parts
Ensure wide-area chassis grounding of the inactive metal parts when
mounting the equipment. Properly implemented grounding creates a uniform
reference potential for the control system, and reduces the effects of
picked-up interference.
Chassis grounding is understood to mean the electrical connection of all
inactive parts. The entirety of all interconnected inactive parts is the chassis
ground.
Inactive parts are conductive parts which are electrically isolated from active
parts by basic insulation, and can only develop a voltage in the event of a
fault.
The chassis ground must not develop a dangerous touch voltage, even in
the event of a fault. The ground must therefore be connected to the protective
ground conductor. To prevent ground loops, locally separated ground
elements such as cabinets, structural and machine parts, must always be
connected to the protective ground system in star configuration.
Ensure the following when chassis grounding:
Connect the inactive metal parts with the same degree of care as the
active parts.
Ensure low-impedance metal-to-metal connections, e.g. with large-area
good quality contact.
When you are incorporating painted or anodized metal parts in the
grounding, these insulating protective layers must be penetrated. Use
special contact washers or remove the insulating layer.
Protect the connection points from corrosion, e.g. with grease.
Movable grounded parts such as cabinet doors must be connected via
flexible grounding strips. The grounding strips should be short and have a
large surface because the surface is decisive in providing a path to ground
for high-frequency interference.

Grounding strips
If there are no large-area metal-to-metal connections, you must
connect inactive metal parts such as cabinet doors and supports
with grounding strips. These should be short and have a large surface.
Cabinet members
The cabinet members should have a large-area connection to the
cabinet housing (metal-to-metal connection).
Mounting bracket for subrack
There must be a large-area metal-to-metal connection between
cabinet member and mounting bracket.
Signal lines
In the case of shielded signal lines and data lines, the shield must be
secured to the protective conductor bar or an additionally fitted shield
bar using large-area cable clamps.
Cable clamp
The cable clamp must enclose and make contact with the shield braid
over a large area.
Shield bar
This bar must have a large-area connection to the cabinet members
(metal-to-metal connection). It serves for grounding the cable shields.
Protective conductor bar
The protective conductor bar must have a large-area connection to
the cabinet members (metal-to-metal connection). The protective
conductor bar must be connected to the protective conductor system
via an external conductor (at least 10 mm2). This is essential for
providing a reliable path to ground for fault currents and interference
currents.
Conductor to the protective conductor system (ground point)
The conductor must have a large-area connection to the protective
conductor system (ground point).

3.2.3 Example of Rack and Wall Mounting for EMC
To operate your control system in a low-interference environment whilst
observing the permissible ambient conditions (see “Technical
Specifications”), you can mount the programmable controllers on racks or
directly on walls.
Picked-up interference should be given a path to large metal surfaces. You
should therefore secure standard sectional rails, shield and protective
conductor bars to metal structural elements. For wall mounting in particular,
installation on reference potential surfaces made of sheet steel has proved
advantageous.
When installing shielded cables, provide a shield bar for connecting the cable
shields. The shield bar can also be the protective conductor bar.
Ensure the following for rack and wall mounting:
Suitable contacting aids should be used on painted and anodized metal
parts. Use special contact washers or remove the insulating protective
layers.
Provide large-area, low-impedance metal-to-metal connections when
securing the shield/protective conductor bar.
AC conductors must be covered.

3.3.1 Routing of Cables
This section covers the routing of bus, signal and supply lines. The purpose
of cable routing is to suppress crosstalk between cables laid in parallel.
For electromagnetically compatible routing of cables and lines, it is
expedient to subdivide the lines into the following line groups and lay the
groups separately.
Shielded bus and data lines (for programmer, OP, SINEC L1, SINEC L2,
PROFIBUS, PROFIBUS DP, printer, etc.)
Shielded analog lines
Unshielded lines for DC voltage 60 V
Unshielded lines for AC voltage 25 V
Coaxial cables for monitors
Unshielded lines for DC voltage > 60 V and 400 V
Unshielded lines for AC voltage > 25 V and 400 V
Unshielded lines for DC and AC voltage > 400 V

Lines can be laid in common bundles or cable ducts.
Lines must be laid in separate bundles or cable ducts (without
minimum clearance).
Lines within cabinets must be laid in separate bundles or cable
ducts; outside the cabinets but within buildings, they must be laid
over separate cable routes with a clearance of at least 10 cm.
Lines must be laid in separate bundles or cable ducts with a
clearance of at least 50 cm.
Outside buildings, lay the lines on metal cable trays if possible. Provide the
joints between cable trays with an electrical connection and ground the cable
trays.
When laying lines outside buildings, you must observe the valid lightning
protection and grounding measures. The following applies in general:
!Caution
Where cables and lines for SIMATIC S5 controllers are to be laid
outside buildings, you must apply measures for internal and external
lightning protection.
Outside the buildings, lay your lines either
in metal conduit grounded at both ends,
or
in concreted cable ducts with continuously connected reinforcement.
Protect the signal lines from overvoltages by means of
varistors
or
inert gas-filled surge diverters.
Fit these protective devices at the cable entry into the building.
Note
Lightning protection measures always require an individual assessment of
the entire installation. For clarification, please consult your Siemens regional
office or a company specializing in lightning protection.
Ensure adequate equipotential bonding between the connected equipment
(see Section 3.3.2).

3.3.2 Equipotential Bonding
Between separate sections of an installation, potential differences can
develop if
Programmable controllers and I/O devices are connected via a
non-floating link, or
Cable shields are connected at both ends and are grounded at different
parts of the system.
Different AC supplies, for example, can cause potential differences. These
differences must be reduced by installing equipotential bonding conductors to
ensure functioning of the electronic components.
The following points must be observed for equipotential bonding:
The lower the impedance of the equipotential bonding conductor, the
greater is the effectiveness of equipotential bonding.
Where shielded signal lines are laid between the relevant sections of the
system and connected at both ends to the ground/protective conductor, the
impedance of the additional equipotential bonding conductor must not
exceed 10 % of the shield impedance.
The cross-section of the equipotential bonding conductor must be rated
for the maximum circulating current. The following cross-sections of
copper have proved to be satisfactory in practice:
-16 mm of copper for equipotential bonding conductors
of up to 200 m in length
-25 mm of copper for equipotential bonding conductors
of more than 200 m in length.
Use copper or zinc-plated steel for equipotential bonding conductors.
They must be given a large-area connection to the ground/protective
conductor and protect it from corrosion.
The equipotential bonding conductor should be laid so that the smallest
possible areas are enclosed between the equipotential bonding conductor
and signal lines.

3.3.3 Shielding of Cables and Lines
Shielding is a method of attenuating magnetic, electrical or electro-magnetic
interference fields. Interference currents on cable shields are given a path to
ground via the shield bar which is electrically connected to the housing. A
low-impedance connection to the protective conductor is particularly
important so that these interference currents themselves do not become an
interference source.
Where possible, only use lines with a braided shield. The coverage density of
the shield should be more than 80 %. Avoid lines with a foil shield because
the foil can be very easily damaged by tensile strain and compression during
fitting; this results in reduced effectiveness of the shield.
As a rule, line shields should always be connected at both ends. This is the
only way to achieve a good degree of interference suppression in the higher
frequency region.
Only in exceptional cases should the shield be connected at one end only, as
this only achieves attenuation of the low frequencies. Single-ended shield
connection may be more advantageous when:
an equipotential bonding conductor cannot be laid;
analog signals (of a few mV or A) are to be transmitted;
foil (static) shields are used.
As a rule, line shields should always be connected at both ends. This is the
only way to achieve a good degree of interference suppression in the higher
frequency region.
With data lines for serial communication, always use metal or metallized
connectors. Secure the shield of the data line to the connector case. Do not
connect the shield to pin 1 of the connector.
For stationary operation, it is advisable to fully strip the insulation from the
shielded cable and connect it to the shield/protective conductor bar.
Note
In the event of potential differences between ground points, a circulating
current may flow through the shield connected at both ends. In this case,
install an additional equipotential bonding conductor (see Section 3.3.2).

Please observe the following points when connecting the shield:
Use metal cable clamps for securing the braided shield. The clamps must
enclose the shield over a large area and provide a good contact. 1)
Connect the shield to a shield bar immediately after the cable entry into
the cabinet. Route the shield as far as the module but do not connect it
there again.

3.3.4 Special Measures for Interference-Free Operation
As a rule, inductances such as contactor or relay coils controlled by
SIMATIC S5 do not require external quenching elements in the circuit,
because the quenching elements are already integrated in the modules.
Inductances should only be fitted with quenching elements
when SIMATIC S5 output currents can be switched off by additionally
fitted contacts, such as relay contacts. In this case the integrated
quenching elements in the modules are no longer effective;
if they are not controlled by SIMATIC S5 modules.
You can place freewheel diodes, varistors or RC networks in circuits with
inductances.

A power socket should be fitted in each cabinet for the AC supply to
programmers. The sockets should be powered from the distribution system to
which the protective conductor for the cabinet is also connected.
Use incandescent bulbs, such as LINESTRA lamps, for cabinet lighting.
Avoid using fluorescent lamps because they generate interference fields. If
the use of fluorescent lamps cannot be avoided, apply the measures shown in

3.4 Power Supplies for Programmable Controllers and I/Os
This section describes:
Which circuits you must distinguish in the control system and which
demands are made on the power supply.
Connection and grounding concept with higher-level infeed from
grounded, centrally grounded and ungrounded supplies.
Connecting the power supply to non-isolated and isolated modules.
3.4.1 Power Supplies for Control Systems with SIMATIC S5
For control systems with SIMATIC S5, you will need:
A power supply for the internal PLC circuits (control power supply)
and a load power supply for the input and output circuits.
The power supply for the internal PLC circuits powers the CPU and the
modules used.
Note
Ensure that the control power supply is not overloaded. Make a current
addition and estimate the current drawn by all modules.
The load power supply feeds the input and output circuits (load circuits) as
well as sensors and actuators. Only a power supply which offers safe
electrical isolation from the AC system may be used for the 24 V DC supply.
!Caution
Only safety-separated low voltage DC 60 V may be used for the
24 V DC supply. The safety separation can be implemented according to the
requirements of, amongst other sources, VDE 0100, Part 410/HD
384-4-41/IEC 60364-4-41 (functional extra-low voltage with safety
separation) or VDE 0805/EN 60950/IEC 60950 (safety extra-low voltage
SELV) or VDE 0106, Part 101.

The electronic short-circuit protection of digital output modules only
responds when 3-times the rated current is exceeded. You should therefore so
design the load power supply units that the unit can supply the current
required for shutting down in the event of a short-circuit at one output.
In the event of short-circuits at digital outputs, if the load power supply is not
adequately rated, a current which is higher than the rated current can flow for
a longer period without responding of the electronic short-circuit protection
of the DQ module. Operation in the overload region can destroy the module.
If you use non-floating modules, you must create a common reference
potential for the internal control circuits of the PLC and for the load circuits.
The reference potential of the load power supply should therefore be
connected to the ground terminal of the PLC (PE or protective conductor
terminal). The ground terminal is permanently connected to the internal
reference potential of the controller.
Note
If you use switched-mode power supply units for floating analog modules
and BEROs, you must fit an AC system filter to the input of the power
supply.
3.4.2 Connecting the Programmable Controller and Load Power
Each of the following figures shows a circuit example for connecting the
control and load power supplies as well as the grounding concept for
operation from:
Grounded supplies
Centrally grounded supplies
Ungrounded supplies
When assembling the control system, observe the following explanations.
The text contains identification numbers relating to Figures 3-8 to 3-10.
For the programmable controller, sensors and actuators, you must fit a
main switch to DIN VDE 0113, Part 1, or an isolating device to
DIN VDE 0100, Part 460. If an AC plug is used as the isolating device,
the socket must be in the vicinity of the central controller and must be
easily accessible (VDE 0805, 1.7.2). These devices are not required in the
case of a subsystem where the appropriate devices are fitted at a higher
level.
The circuits for sensors and actuators can be given group protection for
short-circuit and/or overload . According to VDE 0100, Part 725,
single-phase protection is required; and all-phase protection to
DIN VDE 0113, Part 1.

For 24 V DC load circuits, you require a load power supply unit with
safety separation. If an AC plug is used as the isolating device, the socket
must be in the vicinity of the central controller and easily accessible
(VDE 0805, 1.7.2).
Unregulated load power supply units require a reservoir capacitor
(rated at 200 mF per 1 A load current). Connect the capacitor in parallel
with the output terminals of the load power supply.
According to DIN VDE 0113, Part 1, control systems with more than five
items of electromagnetic apparatus require isolation by a transformer;
according to DIN VDE 0100, Part 725, it is recommended .
Load power supplies should be grounded if possible . Provide a
detachable connection to the protective conductor at the load power
supply unit (terminal L- or M) or on the secondary side of the isolating
transformer.
!Caution
For ungrounded power supplies, you must provide insulation monitoring if:
hazardous system states can be caused by double faults;
there is no safety separation;
circuits are operated with voltages of more than 120 V DC;
circuits are operated with voltages of more than 50 V AC.

In systems with their own transformers or generators, the PLC is connected
to the central ground. A detachable connection should be provided so that
ground faults can be measured.
The PLC should be insulated from cabinet/protective conductor potential. To
maintain this isolated arrangement, all connected devices must be operated
with capacitive grounding or ungrounded. For this reason, programmers
should only be powered via an isolating transformer.

Shown in the following sections are the specical features when installing
non-floating and floating modules.
In an installation with non-floating modules, the reference potentials of the
control circuit (0 Vint) and load circuits (0 Vext) are electrically connected.
The reference potential of the control circuit (0 Vint) is given by the PE or
protective conductor terminal and must be connected to the reference
potential of the load circuit via an externally laid conductor.
Shown in the following figure is a simplified installation with non-floating
modules. The arrangement is independent of the grounding concept. The

Note
For 24 V DC digital output modules with electronic short-circuit protection,
you must ensure that the reference potential of the load power supply is
connected to terminal L- of the module. If this connection is missing (e.g.
open-circuit), a typical current of 15 mA can flow at the outputs. This output
circuit is sufficient
to prevent energized contactors or relays from being released
and to energize high-resistance loads (e.g. miniature relays).
With floating modules the control circuit and load circuit are metallically
isolated.
An arrangement with floating modules is required
for all AC load circuits and
for DC load circuits which cannot be coupled. The reasons are, for
example, different reference potentials of the sensors or grounding of the
positive terminal of a battery.

3.5 Interference-Free Installation of Centralized and Distributed
Interface Circuits
Subjects described in the following sections are the shielding and grounding
concept with centralized and distributed interface circuits.
Information on component selection, the mechanical arrangement and wiring
can be found in the appropriate reference manuals for the interface modules.
Note
If you use components which are not approved for the installation of a
centralized or distributed interface circuit, interference rejection may be
impaired.
3.5.1 Interference-Free Installation of Centralized Interface Circuits
When you connect the central controller and expansion unit centrally via
suitable interface modules, no particular shielding and grounding measures
are required. Ensure, however, that
all subracks are interconnected at a low resistance;
the subracks in a grounded arrangement have star-configuration
grounding;
the contact springs of the modules are clean and not bent, which could
affect the path to ground for interference currents.
3.5.2 Interference-Free Installation of Distributed Interface Circuits
If you interconnect the central controller and expansion unit in a distributed
arrangement using suitable interface modules, no particular shielding and
grounding measures are usually required. Only in industrial environments
with an extremely high level of interference is there a need for special
shielding and grounding.
In these cases, please observe the following points:
Cable shields should be connected to the shield bar in the cabinet,
immediately after the cable inlet;
- insulation is fully stripped from the cable for the purpose;
- braided shields are secured to the shield bar with as large an area as
possible (e.g. with metal ties which enclose the shield over a large
area).
Shield bars should be connected to the frame or cabinet panel over a large
area.
Cable shields should be connected to the cabinet conductor.

With distributed interfacing (IM 304/IM 314 and IM 301/IM 310), ensure
that the VDE specifications for laying the protective ground are complied
with; distributed interfacing is non-floating.
The measures described above are shown in the following figure. If the
permissible potential difference between ground points can be exceeded, you
must install an equipotential bonding conductor (cross-section 16 mm2 of
copper).

With distributed interfacing, you must use the prefabricated connecting
cables. You may have excess lengths of up to 100 m when installing the
connecting cable. These excess lengths must be bifilar-wound and deposited
at a point which is protected from electromagnetic interference.

3.6 Interference-Free Connection of Monitors
These sections cover the following topics:
Floating connection of cables at video inputs
Shielding and grounding concept
Information on selecting the components can be found in Catalog ST80.
3.6.1 Interference-Free Connection of a Monitor to the CP of the
S5 Controller
Operator control and process monitoring systems from the COROS product
family can be used with monitor connections. The physical arrangement of
apparatus and the interference level of the environment are important for the
interference-free connection of monitors to SIMATIC S5 control systems.
The choice of monitor and video cables is governed by the following:
whether the monitor and PLC are to be operated under low-interference
conditions or
under industrial conditions.
Where the monitor and PLC are installed under low-interference
environmental conditions and operated over short distances, the monitor and
PLC are at almost the same ground potentials. Interference and ground loop
disturbances are therefore not expected.
In these cases, you can drive the monitor both via TTL signals and via analog
signals. Digital cables or single-shielded coaxial cables can be used to
transmit the video signals. Note that the braided shield of the coaxial cable
serves as the return conductor and must not be connected to the shield bar.
The monitor and communication processor (CP) are interconnected without
additional shielding and grounding.
Where the monitor and PLC are installed under harsh industrial conditions
and operated over great distances, the devices may be at different ground
potentials. These different ground potentials may cause interference and
ground loop disturbances.

In these cases, double-shielded coaxial cables (triaxial cables) must be used
to transmit the video signals. The inner braided shield of the coaxial cable
serves as the return conductor and must not be connected to the shield bar.
The outer braided shield provides a path to ground for interference currents
and must be incorporated in the shielding and grounding measures.
To avoid ground loops, the electronics ground and housing ground of the
monitor must be independent. This requirement is met when:
the electronics and housing grounds of the monitor are metallically
isolated,
or the electronics and housing grounds are connected via a
voltage-dependent resistor (VDR) fitted by the manufacturer of the
monitor.
3.6.2 Shielding and Grounding
If the monitor and PLC are used under harsh industrial conditions, you must
ensure the following at the PLC end:
Cable shields should be connected to the shield bar in the cabinet,
immediately after the cable inlet;
- the video cables should be fully stripped;
- the outer braided shield should be secured to the shield bar of the
PLC over as large an area as possible (e.g. with metal ties which
enclose the shield or with cable clamps).
Shield bars should be connected to the frame or cabinet panel over a large
area.
Shield bars should be connected to the ground point of the cabinet.
You must ensure the following at the monitor end:
Separate the electronics ground and housing ground.
- Remove the jumper at the monitor to separate the two grounds.
- Fit touch protection at the video sockets because hazardous touch
voltages of more than 40 V may be present at the sockets after
separation of the grounds.
Connect the ground clamp of the monitor to the protective conductor.
Connect the cable shields to the ground clamp of the monitor;
- fully strip the video cables;
- secure the outer braided shield to the ground clamp of the
monitor over a large area.

3.7 Selection and Installation of Cabinets with SIMATIC S5
The following criteria must be observed when selecting and dimensioning a
cabinet:
Ambient conditions at the point of installation of the cabinet
Clearances for power supplies and subracks
Total power dissipation of components in the cabinet
The ambient conditions at the point of installation of the cabinet
(temperature, humidity, dust, effects of chemicals) govern the required
degree of protection of the cabinet (IP XX) as shown in the following figure.
Further information on types of protection can be found in IEC 529.

3.7.2 Clearances in Cabinets
You must first define the components to be fitted in the cabinet. Then
calculate the total power dissipation of the individual components. The
following stipulations must be observed:
The expansion units can be accommodated with the respective central
controller in one cabinet, or in two or more cabinets (centralized or
distributed).
On account of the required clearances and maximum permissible
installation height for control elements, a maximum of three SIMATIC S5
devices can be arranged one above the other.

3.7.3 Removal of Power Dissipation from Cabinets
The power dissipation that can be removed from a cabinet is governed by the
cabinet design, its ambient temperature and the arrangement of equipment in
the cabinet.
Shown in the following figure is a diagram with guide values for the
permissible ambient temperature of a cabinet measuring
600 x 600 x 2200 mm, as a function of power dissipation. These values only
apply to the arrangement of equipment in the cabinet as given in Section
3.6.2. Further details can be found in Catalogs NV21 and ET1.

Note
When fitting the subracks of the S5-135U/155U series, the maximum power
dissipation which can be removed by the fans must not be exceeded. The
maximum removable power dissipation per unit with a supply air
temperature of 55 °C is 250 W. This value is increased by 20 W for each
reduction in supply air temperature by 1 °C.
Installation Guidelines
3-38 System Manual
C79000-G8576-C199-07
!Caution
Modules with a hard disk drive can only be used at an ambient temperature
of up to 50 °C.
3.7.4 Examples for Determining the Type of Cabinet
The following example shows the maximum permissible ambient
temperature with various cabinet types and the same power dissipation.
Example
The following equipment configuration is given:
1 Central controller 200 W
2 Expansion units, 250 W power dissipation each 500 W
1 Load PS, 24 V/40 A, 6EV1 362-5BK00 (full load) 200 W
Total power disspation 900 W
From Figure 3-16, with a total power dissipation of 900 W, the maximum
ambient temperatures given by the table are as follows:
Cabinet Design Max. Permissible Ambient
Temperature
Closed, with natural convection and forced
circulation (Curve 3) (Operation not possible)

3.7.5 Determining the Power Dissipation of Modules
The power dissipation of the modules can be found in the technical
specifications of the catalogs or manuals. If these values are not yet
incorporated in the technical specifications, they can be easily calculated
from the current consumption. The value of current consumption must be
multiplied by the corresponding voltage value.

Central Controllers and Expansion Units
Power Supply Units
The S5-135U/155U programmable controller comprises a central controller
(CC) and, depending on the configuration, one or more expansion units
(EUs). Expansion units are connected when there are unsufficient central
controller slots, or when you wish to position I/O modules as closely to the
process as possible (see also Chapter 2).
With the central controllers and some expansion units, the modules are
directly powered and cooled via the integrated power supply plug-in module.
With all other expansion units, power is supplied via the IMs from the CC
(see also Chapter 7).

The housing consists of bolted sheet-steel sections with ventilation openings
at the top and bottom. The housing contains the bus PCB for electrical and
logical interconnection of the modules. All the slots have guiderails which
accept the modules. Male and female connectors are thus precisely
positioned. There is a locking bar at the top of the housing to prevent the
modules from becoming accidentally detached. Modules with individual
locking are secured in the lower sectional rail. There is a cable duct for
incoming and outgoing cables at the front of the housing.
The power supply unit with the fans is situated in the lower part of the central
controller frame. Depending on the type of power supply, the input voltage is
either 24 V DC or 230/120 V AC. The AC version can be adjusted to the
required AC voltage with a selector switch.

The modular packaging technique allows variable configuration of a CC with
modules and its adaptation to the particular automation task.
The various modules carry out the following tasks:
CPU
The CPU processes the input signals of the PLC according to the user
program, and emits the results as output signals. The following CPUs can
be used in the S5-135U/155U PLC
– CPU 948
– CPU 928B
– CPU 928
– CPU 922
Coordinators
By using a coordinator, you can configure the S5-135U/155U as a
multiprocessor controller with up to four task-oriented CPUs in different
combinations. Each CPU processes its program independently of the
others.
I/O modules
The I/O modules provide the link to the process.
IP module
The intelligent I/O modules (signal pre-processing modules) off-load the
CPU by independently executing compute-intensive tasks such as
controlling, counting and positioning.
Interface modules (IMs)
If your CC has insufficient slots to insert all the modules required for your
automation task, you can increase the number of modules with expansion
units. The IM modules provide the link between central controller and
expansion units.
CP module
CP modules allow point-to-point communication for data interchange
between two PLCs, between one PLC and an external unit, between one
PLC and a SINEC bus system or between one PLC and the COROS
operator control and process monitoring system. You can use additional
CP modules, such as the CP 581, CP 516, for the acquisition, storage,
administration and preprocessing of large volumes of data.
VP module
VP modules enable the local acquisition and displaying (visualization) of
process data of a PLC of the SIMATIC S5.

Proceed as follows to fit the modules:
Step Action
1Disconnect the CC from system power.
2Slacken the two screws with which the locking bar is fixed to the subrack.
3Pull the locking bar forward to its end stop.
– The rail swivels up.
4If there is a locking pin on the lower part of the module, turn it to the
horizontal position.
5Grasp the module at the front plate, insert it into the lower and upper
guide rails and push it in.
– The connectors at the rear will engage in the sockets on the
backplane bus, and the release lever on the lower part of the
module will be horizontal.
6If a locking pin is fitted, push it in and rotate it 90 degrees.
– If you have correctly fitted the module so far, it should no longer
be possible to pull it out of the subrack.
7Swivel the locking bar down and push it back into the subrack.
8Retighten the two screws on the locking bar.
Some I/O modules can also be fitted or removed during operation. Consult
the reference manuals for the I/O modules, under “Release circuit.”
Free slots can be covered with dummy front plates. This improves the flow of
cooling air in the unit. See the ordering information for order numbers.
The connecting cables of CPUs, communication processors and EU interface
modules are connected with metal front connectors.
There are two types of metal front connector:
A metal front connector with slide lock is secured after plugging it in,
by sliding the lock downward.
A metal front connector with milled screws is secured to the unit with
the screws.
Note
Ensure that the connectors are assigned to the correct modules to avoid
damage.
The connection of signal lines for the I/O modules is described in Chapters 8
and 9.

chapters of the manual in which the subject is explained in detail.
To ensure a straightforward sequence for the startup, commence with one
CPU and no EUs.
Proceed according to the following steps to place the CC in operation:
Step Action
1Install the PLC so that the supply of air and exhaust air are unimpeded. If
you fit two or more units (CC and EU) in one cabinet, observe the
clearances and use baffles where necessary (see Chapter 3).
2Fit a lithium battery (see Sections 4.3 and 4.4) or connect an external
backup battery and connect the rechargeable battery.
3Fit the CPU and set the mode switch to STOP.
4Connect the power supply and connect the 24 V DC load supply to the
monitoring input. Check the setting of the voltage selector switch
(on 230/ 120 VAC power supplies). Fit a protective cover over the
AC terminals.
5Switch on the power and, if present, the 24 V load supply.
Position the “Power” switch I.
Reaction: Green LEDs “Power Supply ok” in the “DC 5 V” field and in the
“DC 15/24 V” field light up.
6Hold the CPU switch in the OVERALL RESET position and move the
switch from ST OP to RUN.
Reaction: The “Stop” LED flashes rapidly.
7Repeat Step 6.
Reaction: The “Stop” LED lights up constantly.
8Keep the pushbutton in the RESET position and move the switch from
STOP to RUN.
Reaction: Green “Run” LED lights up, “BASP” LED (output inhibit) goes
off.

4.2.1 Technical Description of the Expansion Units
The design of the EUs is comparable to that of the CC: they comprise a
compact housing with a type-dependant number of slots for modules and,
according to the type of EU, a cable duct, an integral power supply unit or
fan subassembly.
The mounting dimensions of the EU 183U, EU 184U and EU 185U are the
same as those of the 135U/155U CC (see Figs. 4-3 and 4-4). The EU 187U
has neither power supply unit nor cable duct. Its overall height and depth are
therefore different from those mounting dimensions of the other EUs.

The power supply units offer the following functions:
System power supply
All the system voltages required for operation of the modules in a CC or
EU are supplied.
Power supply for backup (in the CC and EU 185):
A lithium battery or an external battery ensure data backup when the
system voltage is switched off or fails.
– The lithium battery remains in the CC/EU and ensures backup, even
during replacement of the power supply unit
– Instead of the lithium battery, an external battery can be connected for
data backup purposes. Situated on the front plate of the power supply
unit are two sockets to connect an external battery.
The rechargeable battery (in the power supply) continues to back up while
either the lithium battery or external battery is being replaced or fails,
ensuring that no data are lost.
Heat removal
Three independent fans which are individually replaceable during
operation remove the dissipated power. If a fan fails, the supply voltage
for this fan is switched off and the other two fans continue operation at
increased speed.
The power supply units contain monitoring functions to detect the following
faults:
Failure of system voltage
Failure of output voltages
Failure of an externally applied 24 V DC load voltage (voltage monitor)
Fan failure or inadequate air flow
Lithium battery failure
Rechargeable battery failure
In this context, a voltage failure is equivalent to a drop of the monitored
voltage below a preset limit (see Section 4.3.6 of the Technical
Specifications).
The failure of a monitored function is signaled by the power supply units:
via LED indicators on the front plate;
via relays with which signaling circuits can be switched;
via signals to the S5 bus.

Whether or not you require a lithium battery depends on what type of backup
you require for your system. The following table will help you to decide.
IF... THEN...
You require long backup times and do not want to
supply an external backup voltage, you need a lithium battery.
You require redundant backup and do not want to
supply an external backup voltage, you need a lithium battery.
Short backup times are suf ficient, you do not need a lithium
battery.
You do not require redundant backup, you do not need a lithium
battery.
The lithium battery must be ordered separately (see Ordering Information).
The backup battery (type C) contains lithium (more than 0.5 g) and is
delivered separately from the power supply unit, because of special shipping
regulations.
Depending on the manufacturer, the battery’s plus pole may have a protective
cover. You must remove this cover before you place the battery in the battery
compartment.
!Caution
Improper replacement of the battery can result in the danger of explosion.
If should only be replaced by the same type or an equivalent one
recommended by the manufacturer. Used batteries should be disposed of
according to the manufacturer’s instructions.
The backup battery must be fitted before the programmable controller is
started up. Without a backup voltage, the PLC will remain in the Stop state
after system voltage is switched on.
Only use battery compartments marked -A1155-B21 (red label).
Fit the lithium battery in the following steps:
Step Action
1Slide the battery compartment cover (A) downwards.
2Pull the battery compartment (B) out.
3Insert the lithium battery in the battery compartment.

!Warning
Risk of danger to persons and property, danger of giving off harmful
substances.
If handled incorrectly, a lithium battery can explode. If disposed of
incorrectly, old lithium batteries can release harmful substances. You must
therefore observe the following guidelines:
Do not throw new or discharged batteries onto a fire and do not solder
onto the body of the cell (max. temperature 100 °C (212 5F)). Do not
recharge them. Order your replacement battery from Siemens only (for
order number see ordering instructions). This ensures that you only use a
short-circuit-protected type.
The lithium battery is subject to regulations for hazardous materials. You
should observe these regulations when you ship the battery, for example,
by using the original packaging.
Used batteries should be returned to the manufacturer or a recycling
station if possible or disposed of as hazardous waste. The guidelines for
transporting hazardous materials should be observed.
If you want to start up one of the central controllers or expansion units
without a battery, you can do either of the following:
You can connect only the rechargeable battery, or
You can supply an external backup voltage.
Apply a backup voltage of 4.5 V DC via the input sockets labelled “Ext.Batt.
DC 4.5 V.” The input sockets are situated on the front panel of the power
supply. Ensure that you have the correct polarity.

4.3.5 Description of Internal Sequences in the Power Supply Unit
Given in this section is background information on internal sequences in the
power supply unit.
The behavior of the power supply unit after a system supply failure is
governed by the duration of the failure:
IF the system supply failure... THEN...
is shorter than the stored energy time
for power failure the PSU output voltages are within tolerance
ranges; no indication appears on the front plate
and no signal is sent to the S5 bus.
is longer than the stored energy time
for power failure a data save routine is initiated on the
CPU/CPUs and an output inhibit is issued.
To ensure data backup, your CC and EU 185 are provided with a lithium
battery, and the power supply unit with a rechargeable battery.
In the event of system supply failure or switch-off, data backup is provided
by the lithium battery and, in the event of battery failure, by the rechargeable
battery which is permanently recharged to remain constantly operative.
After replacement of a defective lithium battery, the new one resumes data
backup and you must acknowledge the fault LED on the front panel.
As the rechargeable battery is withdrawn during the replacement of a power
supply unit, data backup is temporarily performed by the lithium battery.

If a fan fails (its speed decreases) a fault is indicated, i.e. the red LED
assigned to the fan lights up:
“Fan 1” LED = left fan failed
“Fan 2” LED = middle fan failed
“Fan 3” LED = right fan failed
If a fan fails, the following takes place:
Stage Description
1A fan fails.
Result: – The red LED assigned to the fan lights up.
2Contacts 9 and 10 in the “Warning” relay are closed.
3The faulty fan is switched off.
4The other two fans operate at increased voltage and an audibly higher
speed.
If another fan fails, the following takes place:
Stage Description
5 Another fan fails.
Result: – The red LED assigned to the fan lights up.
6Contacts 12 and 13 in the “Alarm” relay are closed.
Result: – “Alarm” LED lights up.
– Two “Fan”-red LEDs light up.
7A data save routine is started and, with the appropriate jumper setting, an
output inhibit is issued.
8The power supply switches off, with the appropriate jumper setting.
When the fault has been cleared (faulty fan replaced, filter mat replaced),
you can reset the fault messages by pressing the Reset button.
!Caution
You can suppress the shutdown of the power supply by opening jumper F-R.
In this case, you must ensure that the power supply is switched off after
60 secs at the latest. This can be achieved with a time relay, for example.
This prevents modules from overheating and being damaged.

submodule produces a stabilized 15 V output voltage from the 24 V output
voltage. The auxiliary submodule is short-circuit protected. The output
voltage is monitored. If the voltage is too low, the green “15/24 V o.k.” LED
on the front plate goes off. If the voltage is too high, the output is
short-circuited by a thyristor.

You can set jumper F-R on the power supply units to choose whether or not
the air flow monitor should switch off the internal supply voltage Vo/p (5 V)
when a fan fails.
Jumper F-R closed: Vo/p shutdown (signaled by contact)
Jumper F-R open: no Vo/p shutdown (signaled by contact)
If one or both fans are at standstill, the signaling relay drops out (monitor
output). The “Fan Fault” LED lights up simultaneously.
Relay contacts 2-1 closed: fan running
Relay contacts 2-3 closed: fan failure
Relay contacts 2-3 closed; this is also the normally closed contact during
power OFF (failsafe).
!Caution
If an immediate shutdown is not possible, jumper F-R must be opened. In
this case you must ensure that the power supply is switched off after 60 s at
the latest. This can be achieved with a time relay, for example. It avoids
overheating and destruction of modules.

As of Version 6 of PSU 6ES5 955-3NA12, you can set jumper RR-LL to
choose whether the signaling relay (monitor output) should switch in the
event of battery failure as well as fan failure:
Jumper RR-LL open (state when delivered): relay will signal only a fan
failure
Jumper RR-LL closed: relay will signal a fan and battery failure.
If the backup voltage fails or a fan is at standstill, or in both cases, the
signaling relay will drop out (monitor output). The “Batt. Low” LED will
also light up.
Relay contacts 2-1 closed: battery backup voltage in order and fan
running
Relay contacts 2-3 closed: backup voltage under 2.7 V or fan failure
Note
The signaling relay in the power supply unit will drop out in the event of a
fan fault or backup battery fault. The user ’s circuitry for the signaling relay
must therefore be suitable for both types of fault.
If the signaling relay drops out because of a backup battery fault and the
programmable controller is therefore switched off, the program in the main
memory may be lost. Loss of program can be avoided if an external backup
voltage (3.4 V) is present at the sockets on the front plate of the power
supply unit during shutdown of the programmable controller.

4.4.3 Installation
To install the power supply unit, push it into the rack. Press it in firmly until
the front plate is at the rack. The spring pressure of the contact elements must
be overcome. Then tighten the two screws to the left and right of the front
plate in the rack. The protective conductor jumper on the left must be
permanently connected to the front plate terminal and the central rack.
!Caution
Power supply units may only be removed when no power is applied.
When the power supply unit is pulled out, the connection between backup
battery and backplane bus is retained; the backup supply for the modules is
thus ensured.
The auxiliary submodule (see ordering information for order number) may
only be inserted when the power is off.
Remove the power supply unit, fit the 15 V auxiliary submodule at the
location shown in the following figure.

4.4.4 Operation
Before placing the power supply unit in operation, please comply with the
following.
This power supply unit does not have potential isolation between its
primary and secondary circuits.
No voltage of more than 50 V may develop between the power supply
outputs and the protective conductor of the power supply unit.
The protective conductor must always be connected, as must the jumper
between CC rack and front plate of the power supply unit.
In the event of overvoltage of the internal DC supply voltages
Vo/p1 = +5 V and Vo/p3 = +15 V, the power supply unit is switched off
retentively. There is a voltage of 0.5 V at Vo/p1 and Vo/p3 in the
Off state (see Section 4.4.6, Technical Specifications, for overvoltage
shutdown).
The storage flip-flop is reset by switching the external supply voltage off
and on again, and the power supply unit is again operational if the
overvoltage was not the result of an internal fault.
You can insert an air filter with filter holder in the bottom of the housing
of the power supply unit.
Observe the voltage level of 3.4 V and correct polarity when applying an
external backup voltage.
Before startup, a lithium backup battery must be fitted or an external
backup battery with a voltage level of 3.4 V DC must be connected.
Without a backup battery, the programmable controller will remain in the
Stop state when system voltage has been switched on. The backup battery
must be fitted for startup. Press the RESET button, then perform an
OVERALL RESET.
The jumper from terminals UH to EN will enable the power supply. You
can lock out the PLC in the event of a fault by means of suitable circuitry
between the monitoring outputs and the EN inputs.

4.4.5 Maintenance
!Caution
Incorrect replacement of the battery can result in the danger of explosion.
It should only be replaced by the same type or an equivalent type
recommended by the manufacturer. Used batteries should be disposed of
according to the manufacturer’s instructions.
You can replace the backup battery without loss of data if the power supply
unit is switched on, or if you apply an external voltage (3.4 V) at the “Ext.
Batt.” sockets. The backup battery must be replaced every 3 years at the
latest, irrespective of memory configuration and backup operation. Replace
the battery as follows:
Step Action
1Pull the cover downwards.
2Pull the battery submodule forwards and out, and remove it.
3Replace the battery.
4Ensure correct polarity.
5Once the new battery is fitted and system voltage is On, press the Reset
button on the power supply unit.

!Caution
Ensure correct polarity when inserting the battery or applying backup
voltage.
!Warning
Risk of danger to persons and property, danger of giving off harmful
substances.
If handled incorrectly, a lithium battery can explode. If disposed of
incorrectly, old lithium batteries can release harmful substances. You must
therefore observe the following guidelines:
Do not throw new or discharged batteries onto a fire and do not solder
onto the body of the cell (max. temperature 100 °C (212 °F)). Do not
recharge them. Order your replacement battery from Siemens only (for
order number see ordering instructions). This ensures that you only use a
short-circuit-protected type.
The lithium battery is subject to regulations for hazardous materials. You
should observe these regulations when you ship the battery, for example,
by using the original packaging. Used batteries should be returned to the
manufacturer or a recycling station if possible or disposed of as
hazardous waste. The guidelines for transporting hazardous materials
should be observed.
The expected service life of the fans (see Technical Specifications) depends
on their operating time, ambient temperature and ambient conditions. In the
event of fan failure during operation, subsequent damage to modules, for
example, is avoided by the activated fan monitor (jumper F-R closed); the
power supply unit is switched off.
In individual cases, a preventive replacement of fans at suitable intervals may
be advisable. Proceed as follows to replace the fans:
Step Action
1Disconnect power from the power supply.
2Remove the power supply.
3Slacken the fixing screws of the fans.
4Pull off the plug-in contacts of the fan supply.
5Connect the plug-in contacts of the new fans.
6Tighten the fixing screws of the fans.
7Refit the power supply.
8Switch the power supply on.
The order numbers for the backup battery and fan unit can be found in the

5.1.3 Interfaces of the CPU 948
This section contains information on the interfaces of the CPU 948.
You can use the PG interface on the CPU 948 either via the front connector
or via the 923C coordinator module and the S5 bus.
Note
Simultaneous operation of the PG interface via the front connector of the
CPU 948 and via the 923C coordinator is not possible. Switching the PG
online without a job request is already sufficient to operate the interface.
Electrically , it is merely a PG interface which can be operated via two
different terminals.
The connection to the PG can be established in every operational state of the
CPU.
You can optionally use the second interface of the CPU 948 -3UA13 or the
CPU 948 -3UA23 as:
A PG interface (for PG and operator panels)
Interface for the RK 512 computer link
Interface for data transmission with procedures 3964/3964R
Interface for data transmission with the “open driver”
Interface for data transmission via the SINEC L1 bus.
To utilize the second interface as the PG interface, you need the
PG submodule.
You need one of the following interface submodules for the
RK 512 computer link, for data transmission with procedures 3964/3964R
and for data transmission with the “open driver”:
V.24 submodule (RS 232C)
TTY submodule
RS422 A/485 submodule (only in the RS422 A module).
To utilize the second interface for data transmission via the SINEC L1 bus,
you need the
SINEC L1 submodule.
The CPU 948 -3UA13 or the CPU 948 -3UA23 is delivered without an
interface submodule. You can operate the CPU 948 -3UA13 or the
CPU 948 -3UA23 without an integral interface submodule. The opening to
accept a submodule in the front plate is closed by a cover. Only remove the
cover to fit an interface submodule.
A description of interface submodules can be found in Section 5.11, and the
order numbers in the ordering information.
A detailed description of the second interface can be found in the
CPU 928B/CPU 948 Communication Manual.

A PG-PLC link via SINEC H1 allows very advanced communication
between the partners. For example, the user software can be loaded into the
CPU 948 up to eight-times faster than with serial communication.
For this link you will need, in addition to the CPU 948, a CPU 143
(Version 2.1) in the PLC and a PG7xx with SINEC H1 connection and the
STEP 5 single-tasking software from Version 6.0 or multi-tasking from
Version 2.0.
Note
You cannot implement communication via SINEC H1 in parallel with the
serial interfaces.
Communication via SINEC H1 is described in detail in the
CPU 948 Programming Guide.

5.2 CPU 948
This section contains the hardware description and the technical
specifications of the CPU 948.
Details on programming the CPU 948 can be found in the
CPU 948 Programming Guide.
5.2.1 Technical Description
This section contains information on the application, design and structure of
the CPU 948.
You can use the CPU 948 in single and multiprocessor operation in the
S5-135U/155U central controller (see Chapter 6).
There are two versions of CPU 948:
The CPU 948-1 offers 640 Kbytes of internal user memory (RAM).
The CPU 948-2 offers 1664 Kbytes of internal user memory (RAM).
A SIMATIC S5 flash EPROM memory card (known as a memory card for
short in the following) can be inserted in the CPU 948 as the storage medium
for user program and user data. The contents of the memory card are copied
into the internal RAM of the CPU upon overall reset.
The programming language is STEP 5 (LAD, CSF, STL, SCL). The CPU 948
processes all STEP 5 operations at very high speed, and uses fast
floating-point arithmetic.
The following program processing levels are possible:
Cyclic
Time-controlled (9 different timebases, real-time controlled, timeout)
Interrupt-driven from the S5 bus (8 process interrupts at block boundaries
via IB0 or, alternatively, 4 system interrupts)
Soft STOP.
The electronic circuitry of the CPU 948, including the RAM, is on two PCBs
of double Eurocard format which are screwed to each other. The two PCBs
must not be separated. The front plate width of the module is 2 2/3 standard
plug-in stations, i.e. 40 mm. In the central controller rack, the CPU 948
occupies two slots.

A PG-PLC link via SINEC H1 allows very advanced communication
between the partners. For example, the user software can be loaded into the
CPU 948 up to eight-times faster than with serial communication.
For this link you will need, in addition to the CPU 948, a CPU 143 (Version
2.1) in the PLC and a PG7xx with SINEC H1 connection and the STEP 5
single-tasking software from Version 6.0 or multi-tasking from Version 2.0.
Note
You cannot implement communication via SINEC H1 in parallel with the
serial interfaces.
Communication via SINEC H1 is described in detail in the
CPU 948 Programming Guide.

5.3 CPU 928B -3UB21
This section contains the hardware description and technical specifications of
the CPU 928B -3UB21.
Details on programming the CPU 928B -3UB21 can be found in the
CPU 928B -3UB21 Programming Guide.
5.3.1 Technical Description
You can use the CPU 928B in single and multiprocessor operation in the
S5-135U/155U central controller (see Chapter 6). Up to four CPUs can be
used.
The CPU 928B is universally applicable, ensuring both very fast bit
processing and very fast word processing.
The following program processing levels are possible:
Cyclic
Time-controlled (9 different timebases)
Real-time controlled
Interrupt-driven (hardware interrupt)
Delayed
The programming language is STEP 5.
The electronic circuitry of the CPU 928B is on one PCB in the double
Eurocard format. The board provides the connection to the S5 bus via two
backplane connectors.
The front plate width is 1 1/3 standard plug-in stations.

For storage of your program, user memory in the form of RAM is integrated
on the board. You can store up to 64 x 210 bytes of code and data blocks here.
For data blocks, the CPU 928B additionally has an integrated DB RAM of
46 3/4 x 210 bytes.
As an external memory medium for user programs and user data, you can use
a memory card 374 with Flash EPROM.
There are two independent interfaces on the front of the CPU 928B.
You can connect programmers and OPs to the first interface.
This PG interface SI1 is permanently installed on the CPU.
You can use PG interface SI1 either via the front connector of the CPU 928B
or via the front connector of the 923C coordinator module.
Note
Simultaneous operation of PG interface SI1 via the front connector of the
CPU 928B and of the coordinator is not possible. Electrically, it is merely a
PG interface which can be operated via two different terminals. Switching
the programmer online without a job request is already sufficient to operate
the interface. If you wish to utilize a second PG interface for connection of a
PG or OP, the connection must be made via the second PG interface with the
PG submodule.
Apart from PG interface SI1, the second interface SI2 can also be used as a
PG interface in parallel with the first one. You can only use the second
PG interface via the front connector of the PG submodule on the CPU 928B.
A detailed description of operations with the two PG interfaces can be found
in the CPU 928B -3UB21 Programming Guide.
The connection to the PG can be established with the CPU in any operational
state.

You can optionally use the second interface of the CPU 928B as:
A PG interface (for PG and operator panels)
Interface for the RK 512 computer link
Interface for data transmission with procedures 3964/3964R
Interface for data transmission with the “open driver”
Interface for data transmission via the SINEC L1 bus (from
Version 6ES5 928-3UB12).
To utilize the second interface as the PG interface, you need the
RG submodule
You need one of the following interface submodules for the
RK 512 computer link, for data transmission with procedures 3964/3964R
and for data transmission with the “open driver”:
V.24 submodule (RS 232C)
TTY submodule
RS422 A/485 submodule (only in the RS422 A mode).
To utilize the second interface for data transmission via the SINEC L1 bus,
you need the
SINEC L1 submodule (from Version 6ES5 928-3UB12).
The CPU 928B is delivered without an interface submodule. You can operate
the CPU 928B without an integral interface submodule. The opening to
accept a submodule in the front plate is closed by a cover. Only remove the
cover to fit an interface submodule.
A description of interface submodules can be found in Section 5.11, and the
order numbers in the ordering information.
A detailed description of the second interface can be found in the
CPU 928B/CPU 948 Communication Manual.
There is an interrupt line in the PLC for each CPU. It can be used when the
reaction to an event must occur with higher priority than the reaction to other
events.
To process an interrupt, cyclic program processing is interrupted and the
program stored in OB 2 (OB for interrupt processing) is inserted (refer to the
CPU 928B -3UB21 Programming Guide for further details).
This interrupt-driven program processing is only possible using an
interrupt-capable digital input module or a suitable operating CP/IP module.
No jumper setting on the CPU 928B is required. Please note, however, that
the usable interrupt line on the backplane bus depends on the CPU slot and
must be set accordingly on the I/O module (see Section 4.1).

You require a user memory submodule (RAM or EPROM) for storage of your
program. You can store up to 64 x 210 bytes of code and data blocks here. For
data blocks, the CPU 928B additionally has an integrated DB RAM of
46 x 210 bytes.
A description of the memory submodules can be found in Sections 5.9 and
5.10; order numbers are given in the ordering information.
There are two independent interfaces on the front of the CPU 928B.
You can connect programmers and OPs to the first interface. This
PG interface SI1 is permanently installed on the CPU.
You can use PG interface SI1 either via the front connector of the CPU 928B
or via the front connector of the 923C coordinator module.
Note
Simultaneous operation of PG interface SI1 via the front connector of the
CPU 928B and of the coordinator is not possible. Electrically, it is merely a
PG interface which can be operated via two different terminals. Switching
the programmer online without a job request is already sufficient to operate
the interface. If you wish to utilize a second PG interface for connection of a
PG or OP, the connection must be made via the second PG interface with the
PG submodule.
Apart from PG interface SI1, the second interface SI2 can also be used as a
PG interface in parallel with the first one. You can only use the second
PG interface via the front connector of the PG submodule on the CPU 928B.
A detailed description of operations with the two PG interfaces can be found
in the CPU 928B Programming Guide.
The connection to the PG can be established with the CPU in any operational
state.

You can optionally use the second interface of the CPU 928B as:
A PG interface (for PG and operator panels)
Interface for the RK 512 computer link
Interface for data transmission with procedures 3964/3964R
Interface for data transmission with the “open driver”
Interface for data transmission via the SINEC L1 bus (from
Version 6ES5 928-3UB12).
To utilize the second interface as the PG interface, you need the
PG submodule.
You need one of the following interface submodules for the
RK 512 computer link, for data transmission with procedures 3964/3964R
and for data transmission with the “open driver”:
V.24 submodule (RS 232C)
TTY submodule
RS422 A/485 submodule (only in the RS422 A module).
To utilize the second interface for data transmission via the SINEC L1 bus,
you need the
SINEC L1 submodule (from Version 6ES5 928-3UB12).
The CPU 928B is delivered without an interface submodule. You can operate
the CPU 928B without an integral interface submodule. The opening to
accept a submodule in the front plate is closed by a cover. Only remove the
cover to fit an interface submodule.
A description of interface submodules can be found in Section 5.11, and the
order numbers in the ordering information.
A detailed description of the second interface can be found in the CPU 928B
Communication Manual.
There is an interrupt line in the PLC for each CPU. It can be used when the
reaction to an event must occur with higher priority than the reaction to other
events.
To process an interrupt, cyclic program processing is interrupted and the
program stored in OB 2 (OB for interrupt processing) is inserted.
(Refer to the CPU 928B Programming Guide for further details.)
This interrupt-driven program processing is only possible using an
interrupt-capable digital input module or a suitable operating CP/IP module.
No jumper setting on the CPU 928B is required. Please note, however, that
the usable interrupt line on the backplane bus depends on the CPU slot and
must be set accordingly on the I/O module (see Section 4.1).

5.5 CPU 928 -3UA21
This section contains the hardware description and technical specifications of
the CPU 928 -3UA21.
Details on programming the CPU 928 can be found in the
CPU 928 Programming Guide.
5.5.1 Technical Description
You can use the CPU 928 in single and multiprocessor operation in the
S5-135U/155U central controller (see Chapter 6). Up to four CPUs can be
used.
The CPU 928 is universally applicable, ensuring both very fast bit processing
(optimized for open-loop tasks) and word processing (optimized for
closed-loop tasks).
The following program processing levels are possible:
Cyclical
Time-controlled (9 different timebases)
Interrupt-driven (hardware interrupt)
The programming language is STEP 5.
The electronic circuitry of the CPU 928 is on one PCB in the double
Eurocard format. The board provides the connection to the S5 bus via two
backplane connectors.
The front plate width is 1 1/3 standard plug-in stations.

System Manual
C79000-G8576-C199-07
For storage of your program, user memory in the form of RAM is integrated
on the board. You can store up to 64 x 210 bytes of code and data blocks here.
For data blocks, the CPU 928 additionally has an integrated DB RAM of
46 x 210 bytes.
Note
The DB RAM is loaded with DB/DX blocks when the user memory is full.
There is an interrupt line (IR) in the PLC for each CPU. It can be used when
the reaction to one or more events must occur with higher priority than the
reaction to other events.
To process a process interrupt, cyclic program processing is interrupted and
the program stored in OB 2 (OB for interrupt processing) is inserted. (Refer
to the CPU 928 Programming Guide for further details.)
This interrupt-driven program processing is only possible using an
interrupt-capable digital input module (e.g. 6ES5 432-...) or a CP/IP module
which operates in this way.

You require a user memory submodule (RAM or EPROM) for storage of your
program. You can store up to 64 x 210 bytes of code and data blocks here. For
data blocks, the CPU 928 additionally has an integrated DB RAM of
46 x 210 bytes.
Note
The DB RAM is loaded with DB/DX blocks when the RAM submodule is
full or an EPROM submodule is plugged in.
A description of the memory submodules can be found in Sections 5.9 and
5.10; order numbers are given in the ordering information.
There is an interrupt line (IR) in the PLC for each CPU. It can be used when
the reaction to one or more events must occur with higher priority than the
reaction to other events.
To process an interrupt, cyclic program processing is interrupted and the
program stored in OB 2 (OB for interrupt processing) is inserted.
(Refer to the CPU 928 Programming Guide for further details.)
This interrupt-driven program processing is only possible using an
interrupt-capable digital input module (e.g. 6ES5 432-...) or a CP/IP module
which operates in this way.

The CPU 922 is particularly suitable for word processing (closed-loop
control and arithmetic calculation). Binary signal processing is also possible.
The following program processing levels are possible:
Cyclic
Time-controlled (1 timebase)
Interrupt-driven (hardware interrupt).
The programming language is STEP 5.
The module is designed as a plug-in PCB of double Eurocard format. The
module provides the connection to the S5 bus via two backplane connectors.
The front plate width is 1 1/3 standard plug-in stations.

You require a user memory submodule (RAM or EPROM) for storage of your
program. You can store up to 64 x 210 bytes of code and data blocks here.
For data blocks, the CPU 922 additionally has an integrated DB RAM of
22 x 210 bytes.
Note
The DB RAM is only loaded with DB/DX blocks when the RAM submodule
is full or an EPROM submodule is inserted.
A description of the memory submodules can be found in Sections 5.9 and
5.10; order numbers are given in the ordering information.
There is an interrupt line (IR) in the S5-135U/155U PLC for each CPU. It
can be used when the reaction to one or more events must occur with higher
priority than the reaction to other events.
To process an interrupt, cyclic program processing is interrupted and the
program stored in OB 2 is inserted. Refer to the CPU 922 Programming
Guide for further details.
This interrupt-driven program processing is only possible using an
interrupt-capable digital input module (e.g. 6ES5 432-...) or a suitably
operating CP/IP module.

RUN LED is lit.
The CPU 922 goes to the stop state when you switch from RUN to STOP.
The red STOP LED then lights up.
You can initiate the Overall Reset, Reset and Restart functions with the
momentary-contact mode switch:
Momentary-contact switch down
With an overall reset, all RAM areas are erased and initialized (both on the
CPU and on a RAM submodule).
Momentary-contact switch up
During a reset, all flags, timers, counters and the process image will be
erased. OB 20 will be invoked. Processing of the user program will start from
the beginning again.
Momentary-contact switch at midpoint
With a restart, processing of the user program will continue from the point of

5.10.3 RAM Submodules with Battery Backup
RAM submodules with battery backup are used when the contents of the
memory submodules must be retained even outside the CPU. You can then
remove the battery-backed 377 memory submodule from the CPU without
loss of data. An integral battery protects the submodule from data loss, and
ensures that the data will be retained until the RAM submodule is used again.
Note
The RAM submodule with battery backup is not a substitute for an
EPROM submodule. The contents can be overwritten by a STEP 5 program.
The battery can discharge if the submodule is at standby for a long time.
This can result in the loss of data.
To protect the battery, the 377 memory submodule has a cover on both sides.
The button cell battery with terminal lugs is secured on the submodule with
screws on two holders. When the grip is swivelled in, you can see the battery
fault LED.
There are three different operational states for the RAM submodule with
battery backup:
In this state
the battery-backed RAM submodule is in the CPU;
the programmable controller (PLC) is switched on (Power On);
and neither the backup battery of the PLC nor the battery of the
RAM submodule is supplying power.
Note
The RAM submodule must not be inserted or removed during the RUN state;
this can result in data corruption, loss of data or CPU malfunctions.

In this standby state of the unit
the battery-backed RAM submodule is in the CPU;
the PLC is switched off (Power Off);
the backup battery of the PLC is providing backup of the
RAM submodule;
the submodule battery is not supplying power.
Note
It is only possible to insert and remove the RAM submodule in this state
without data corruption.
If the backup battery in the PLC fails in this state, the submodule battery
provides backup of the RAM submodule. This prevents loss of data.
In this standby state of the submodule
the RAM submodule has been removed from the CPU;
the submodule battery is providing backup of the RAM submodule;
the contents of the battery-backed RAM are retained.
The battery of the battery-backed RAM submodule is monitored. When the
RAM submodule goes to normal operation (battery-backed RAM is in the
CPU, supply voltage of the PLC is switched on), the battery monitor on the
submodule detects the following faults:
Submodule battery is not present.
Submodule battery is faulty (voltage less than 2.6 V).
The red battery fault LED on the front of the submodule is continuously lit.
Note
A temporary voltage drop of the submodule battery in the standby state, for
example, caused by storage below 0 oC or a battery change, is not detected
by the battery monitor if the voltage dip is corrected by plugging in the
RAM submodule and switching on the PLC. However, the voltage dip may
have led to a loss or corruption of RAM submodule data.

5.11.1 Installing and Removing the Interface Submodules
To use an interface submodule, you must first install it in the CPU (outside
the central controller).
!Caution
Switch off the power supply of the programmable controller before
removing the CPU.
Install your interface submodule in the following steps:
Step Action
1Check the jumper settings of your interface submodule:
PG submodule See Section 5.11.2
V.24 submodule See Section 5.11.3
TTY submodule See Section 5.11.4
RS422 A/485 submodule See Section 5.11.5
SINEC L1 submodule See Section 5.11.6.
When the interface submodule is delivered, the jumpers are
already set so that you can usually fit it immediately.
2Switch off the power supply of your PLC.
3Remove the CPU.
4Remove both screws on the submodule slot.
5Remove the coverplate.
6Insert the interface submodule through the front plate into the
plug-in connector (components in the same direction as the CPU).
7Secure the submodule with the two screws (see step 4).
8Insert the CPU in the central rack.
9Switch on the power supply of your PLC again.

Apart from the transmit and receive lines, the V.24 submodule has a number
of control and signaling lines to CCITT Recommendation V.24/V.28.
However, these control signals are not needed and not used for the standard
procedures of communication types RK 512, 3964/3964R and “open driver.”
(Exception: RTS/CTS with the “open driver”).
The following applies to V.24 signals:
Logic 0 is represented by a voltage U + 3 V
Logic 1 is represented by a voltage U – 3 V
If you fabricate the connecting cables yourself, note that unused inputs at the
partner station may have to be connected to quiescent potential. Further
details can be found in the appropriate manuals and in
CCITT Recommendations V.24/V.28.

The TTY submodule feeds in the current (20 mA) via jumpers in the
connector of the standard connecting cable. The 24 V required for generation
of loop current is taken from the power supply of the PLC. In the quiescent
state, with a correct loop current connection, there should be a flow of 20 mA
(= logic 1). When the current is interrupted there is a logic 0.
The following applies to the TTY signals:
Logic 0 is represented by: no current
Logic 1 is represented by: current (20 mA)
A maximum of 9600 bps is permissible for data transmission with the

Apart from the transmit and receive lines, the RS422 A/485 submodule has a
number of control and signaling lines to CCITT Recommendation X.24 and
ISO 8481. In association with the above types of communication, however,
these control and message signals are not required and need therefore not be
wired. The RS422 A/485 is a differential voltage interface and therefore
exhibits higher rejection of interference than a TTY or V.24 interface.

Multiprocessor Operation/Coordinators
This chapter explains how to install multiprocessor operation in the
S5-135U/155U programmable controller and start operations.
You will require the 923A or 923C coordinator module. The technical
functions of these modules are described.

6.1 Introduction
The S5-135U/155U is a member of the SIMATIC S5 family of programmable
(logic) controllers. The PLC can be used both in single and in multiprocessor
operation with up to four CPUs.
You can arbitrarily combine the CPUs in the central controller at the
CPU slots.
CPU Slot Requirement
CPU 948/CPU 928B/CPU 928 2 slots
CPU 922, 928-3UA21, 928-3UB21,
948-3UA13, 948-3UA23 1 slot
In multiprocessor operation, each CPU processes its individual user program
independently of the other CPUs.
The common S5 bus serves for data interchange with I/O modules, CPs, IPs
and other CPUs. In multiprocessor operation, access of the CPUs to the
S5 bus is controlled by a coordinator. The functioning of this module is
described in Sections 6.5 and 6.6.
For an explanation of data interchange between CPUs in multiprocessor
operation and the arrangement of your STEP 5 program, please consult the
Programming Guide for your CPU.
A coordinator is required in multiprocessor operation. The following exist for
the S5-135U/155U PLC:
923A coordinator (COR A) (is no longer supplied)
and
923C coordinator (COR C).
The coordinator allocates to the CPUs the time divisions in which they can
access the S5 bus (bus enable time), and contains the global memory for data
interchange between the CPUs via communication flags. Additionally, the
COR C contains another memory with four pages for the “multiprocessor
communication” function as well as a serial PG interface with
PG multiplexer function (PG MUX).

6.2 Starting the Multiprocessor Operation
This section guides you through the installation and startup of multiprocessor
operation; the following is assumed:
You are familiar with the use and programming of individual modules in
single-processor operation. If this is not the case, please consult the
relevant chapters in this manual and in the appropriate
Programming Guides.
Note
As soon as a coordinator is inserted in the S5-135U/155U central controller,
all CPUs are automatically in multiprocessor operation irrespective of the
number of inserted CPUs. Even if the coordinator is only operated with one
CPU, the conditions for multiprocessor operation apply to this CPU (DB 1
required, DX 0 possibly required, etc.).
You can use up to four CPUs in the S5-135U/155U programmable controller.
The permissible slots are indicated in Chapter 4.
Startup can be subdivided into the following steps:
Step Action
1Set the number of CPUs (inserted from the left) on the
coordinator.
2If you use communication flags on CPs: Mask out the
communication flag areas on the coordinator.
3Insert the CPUs and the coordinator in the slots provided in the
central controller. The CC must be disconnected from system
voltage.
4Switch on the system voltage and power switch on the power
supply unit.
5Execute an OVERALL RESET on all CPUs.
6Load your STEP 5 user programs in all CPUs (including DB 1,
additionally DX 0 for the CPU 948).
7Execute a RESET on all CPUs.
8Set the mode switch of the coordinator from the STOP to RUN or
TEST setting.

System Manual
C79000-G8576-C199-07
Action Reaction
Switch the supply voltage on. 1. The red STOP LEDs flash
rapidly on all CPUs to indicate:
Overall reset requested.
2. If the test mode is not set at the
coordinator (see Section 6.3)
and the mode switch is not at
the TEST setting:
The red BASP (output inhibit)
LED is permanently lit to
indicate: Digital outputs are
inhibited.
Symptom:
On some CPUs the STOP LED is not lit; the other CPUs are requesting
OVERALL RESET. All CPUs are emitting the BASP (output inhibit) signal.
Remedy:
Check the setting for the number of occupied CPU slots on the coordinator.
Are the CPUs inserted at suitable slots?
Executing an OVERALL RESET on all CPUs:
Ensure that the mode switch on the coordinator is set to STOP. (Precondition:
Steps 3 and 4 have been fully executed.
Action Reaction
Execute the OVERALL RESET for
each individual CPU:
Hold the operating mode switch in
the OVERALL RESET setting;
simultaneously set the mode switch
from STOP to RUN and back to
STOP.
The red STOP LEDs on the CPUs at
which the OVERALL RESET was
executed, light up continuously.
Each CPU additionally emits the
output inhibit signal (BASP LED
continuously lit).

Recommended precondition: The programs of the individual CPUs have
already been tested in single-processor operation.
For details of loading STEP 5 blocks and using the different types of
memory, please consult the relevant Programming Guides of the CPUs and
your PG Manual.
Prerequisites
What? Where?
Data block DB 1 must be present for I/O allocation. in all
CPUs 1)
Data block DX 0 must additionally be present at
CPU 948.
The mode for “Process interrupts via IB 0 = off” must

CPU 1)
1. You must only load the blocks for CPUs with RAM operations; for EPROM operation, the
inserted EPROMs must contain your user program with DB 1 (DX 0).
Data blocks which you have provided for dynamic data storage must be copied after a
RESET by program into the RAM.
Reaction
There is no change in the reactions of step 4 (each CPU still emits the
output inhibit signal: the BASP LED is continuously lit).
Step 6

Executing a RESET at all CPUs:
Action Reaction
Execute a RESET at each individual
CPU:
Hold the MC 1) mode switch at the
RESET setting; simultaneously set the
mode switch from STOP to RUN.
The red STOP LED on each CPU
is continuously lit; each CPU
emits the output inhibit signal.
The CPUs are in the wait state.
1) MC: Momentary-contact
Symptom 1:
The STOP LED of one CPU flashes slowly. When the control bits of this
CPU are read out with the programmer, “DB 1 error” is marked in addition to
the usual information. There is no output of an ISTACK.
Remedy:
Check whether data block DB1 in the CPU was correctly loaded and
programmed.
Symptom 2:
After execution of a RESET:
Undefined states or faults occur at the CPUs (for example, after a RESTART
at CPU 922, it goes to the RUN state although the other CPUs are still at
STOP).
Remedy:
Verify the following points:
Is the coordinator inserted?
Are all modules correctly inserted (engaged)?
Are all modules at the correct slots?

Setting the coordinator mode switch to RUN or TEST:
IF ... THEN ... Reaction
You do not wish to
work in the test mode 1) Set the coordinator
mode switch from
STOP to RUN.
The green RUN LEDs
of all CPUs are
continuously lit. All
CPUs simultaneously
go into the cycle. The
output inhibit signal is
not emitted
(BASP LED = off).
You wish to work in the
test mode (it must be
enabled on the
coordinator) 1)
Set the coordinator
mode switch from
STOP to TEST.
Set the coordinator
mode switch from
STOP to TEST.
1) Test mode and setting: see Section 6.3
Symptom:
All CPUs remain in the Stop state.
Remedy:
Check whether the mode switches of all CPUs are set to RUN.
A subsequent start of individual CPUs is not possible. Switch the coordinator
back to STOP. Execute a RESET at all CPUs and then switch the coordinator
to RUN again.
Note
During the starting phase (processing of the start OBs) the STOP and
RUN LEDs remain off at all CPUs. The RUN LED only lights up
continuously when the CPUs go over to cyclic program processing.
When the coordinator is switched from STOP to TEST, only the CPUs
whose switches are at the RUN setting will operate in the test mode.
If the 923C coordinator is used and the PG interface on the front plate is
not connected to the PG and switched online, the IF FAULT LED lights
up on the 923C coordinator. The indicator can be ignored in this case.

6.3 Coordinator Modes
If, when the supply voltage is switched on, the coordinator mode switch is at
STOP or another stop request is pending, the CPUs remain in the Stop state.
AUTOMATIC RESET or
AUTOMATIC RESTART
If, when the supply voltage is switched on, the coordinator mode switch is at
RUN, an AUTOMATIC RESET or AUTOMATIC RESTART (depending on
DX 0 setting) will take place as long as the mode switches of the CPUs are
also at RUN and the PLC was previously in cyclic operation.
MANUAL START
When you set the coordinator mode switch from STOP to RUN, the CPUs
will execute a start if this was already prepared at all CPUs by appropriate
switch actuation, i.e. the CPUs are in the wait state. As required by the user,
the type of start can be the same for all CPUs or arbitrarily different.
After the start synchronization by the system programs, the CPUs
simultaneously go to RUN (cyclic operation).
The transition of individual CPUs is synchronized - as long as the preset
“start synchronization” in the relevant CPUs has not been changed by
DX 0 programming - i.e. only when each CPU has ended its start do all CPUs
jointly go to cyclic program processing.
If the coordinator mode switch is at the RUN setting and one CPU goes to
the Stop state, all the other CPUs also go to the Stop state. The red STOP
LED(s) on the CPU(s) causing the Stop state flash slowly; the STOP LEDs of
the other CPUs are continuously lit.
Apart from any indication with fault LEDs on the CPU which is the cause, all
CPUs emit the BASP (output inhibit) signal.

!Warning
Since, in the test mode, no CPU can emit a BASP (output inhibit) in the
event of a fault, the test mode must be switched to the inactive state
without fail after completion of startup to avoid a critical or even
hazardous system state.
Before you can go into the test mode with the TEST switch, you have to
enable it on the module. This is achieved differently with the 923A and
923C coordinators.

When the coordinator mode switch is set from STOP to TEST, the CPUs can
be started individually. There is therefore no synchronized transition to
cyclic program processing. The output of signal BASP is suppressed on all
CPUs, even if there is an error.
If an error occurs with a CPU switched to RUN, only this one goes to the
Stop state in the test mode. The error is indicated by slow flashing of the
CPU’s STOP LED. The error at this CPU does not affect other CPUs.
If the test mode is not activated, a changeover from STOP to TEST does not
result in any reaction of the CPUs.

6.4 923A Coordinator Module (is no longer supplied)
6.4.1 Technical Description
This section contains information on the application, design and principle of
operation of the 923A coordinator.
The 923A coordinator module is intended for operation in the
S5-135U/155U PLC. It is required in multiprocessor operation and has the
following functions:
Bus arbitration
To coordinate multiprocessor operation, i.e. the simultaneous use of two
to four CPUs (CPU 928B, CPU 928 or CPU 922).
Communication memory
for the interchange of data between CPUs via communication flags.
Note
The 923A coordinator module cannot be used in multiprocessor operation if
a CPU 948 is fitted in the 135U/155U PLC. If you execute global memory
access in multiprocessor operation (I/O area with addresses 0000H-EFFFH)
with the CPU 928B and/or the CPU 928, you must use the COR 923C as the
coordinator.
The COR 923A is designed as a plug-in PCB of double Eurocard format.
Two 48-way Series 2 blade connectors serve to connect the PCB to the
S5 bus in the subrack.
The front plate width is 1 1/3 standard plug-in stations.
A three-position mode switch is fitted in the front plate for operator
functions.

Bus arbitration
The COR 923A cyclically allocates a bus enable signal to each of the two to
four CPUs in the S5-135U/155U PLC. Only during this time can the relevant
CPU utilize the common S5 bus.
The assignment of bus enable signals takes place in time-division multiplex
operation. On the COR 923A, you set the number of CPUs with jumpers. The
enable time for access to the S5 bus is preset at 2 ms for all CPUs. If the bus
enable signal has been emitted by the coordinator for a CPU, this CPU can
extend the enable time with the bus lock signal. However, the user has no
influence on this.
The bus enable assignment sequence begins with CPU 1 after the
Reset signal is removed by the power supply, and enables the CPUs
in the following order according to the preset number of CPUs:
CPU 1, CPU 2, CPU 3, CPU 4, CPU 1, CPU 2 etc. (see Figure 6-5)

Communication memory
The communication memory comprises a central battery-backed RAM in the
PLC. It has two areas: the communication flags and the semaphores.
The communication flags on the COR 923A allow the cyclic interchange of
data between the CPUs. The semaphores are mainly used to coordinate the
exchange of data in the I/O area.
Please consult the Programming Guides of the CPUs to program these
functions.

6.5 923C Coordinator Module
6.5.1 Technical Description
This section contains information on the application, design and principle of
operation of the 923C coordinator.
The 923C coordinator module can be used in the
S5-135U/155U programmable controller and in the EU S5-185U expansion
unit. There are three main task areas which are, to some extent, independent:
Bus arbitration (only in the central controller)
To coordinate multiprocessor operation, i.e. the simultaneous use of two
to four CPUs (CPU 948, CPU 928B, CPU 928, CPU 922).
Communication memory (only in the central controller)
For the interchange of data between CPUs via communication flags and
data blocks.
Central programmer connection (PG MUX)
For the programming and startup of up to 8 modules via one
PG connection.
To program a programmable controller via the SINEC H1 or
SINEC L1/L2 bus, connect the SINEC CP to the PG connection of the
COR C using the 725 cable (“swing” cable).

The COR 923C is designed as a plug-in PCB in double Eurocard format.
Two 48-way Series 2 blade connectors serve to connect the module to the
S5 bus in the subrack.
The front plate width is 1 1/3 standard plug-in stations.
A mode switch with three settings is fitted in the front plate for other
operator functions.
Faults are indicated by five small red LEDs.
There is a recess with cover in the upper third of the front plate. By removing
the cover, you can operate the DIL switches to set parameters for the module.
You can connect the COR 923C via a 15-pin front connector to a
programmer, OP, operator control panel or the CP 530 and CP 143.
The COR 923C cyclically allocates a bus enable signal to each of the two to
four CPUs in the S5-135U/155U PLC. Only during this time can the relevant
CPU utilize the common S5 bus.
The assignment of bus enable signals takes place in time-division multiplex
operation. On the COR 923C, you set the number of CPUs with
DIL switches. The enable time for access to the S5 bus is preset at 2 ms for
all CPUs. If the bus enable signal has been emitted by the coordinator for a
CPU, this CPU can extend the enable time with the bus lock signal. However,
the user has no influence on this.
The bus enable assignment sequence begins with CPU 1 after the
Reset signal is removed by the power supply, and enables the CPUs in the
following order according to the preset number of CPUs:
CPU 1, CPU 2, CPU 3, CPU 4, CPU 1, CPU 2 etc. (see Figure 6-7)

Figure 6-7 Timing Sequences of the Bus Control Signals
Monitoring for continuous bus assignment
The bus lock signal can only be emitted by the CPU which has already
received a bus enable signal from the COR 923C. The bus enable time is
extended by the duration of the bus lock signal for the CPU (see Figure 6-7).
The factory setting for monitoring of the bus lock signal is 2 ms. If the signal
remains active for a longer duration, the COR 923C emits a signal which
results in a Stop of all CPUs.
The CPU which emitted the bus lock signal for too long a duration, is marked
by the CPU in a readable register under address FEFFH (fault register, see
Figure 6-8). The assigned BUS FAULT LED in the front plate of the
COR 923C lights up. The register is cleared and the LED goes off again
when the signal which led to the Stop state becomes inactive.
Communication memory
The communication memory comprises a central battery-backed RAM in the
PLC. It has three areas: 1) the communication flags (256 bytes), 2) the
semaphores (32), and 3) four memory pages.
The communication flags are located in memory area F200H to F2FFH. The
communication flags enable the cyclic interchange of small volumes of data
between the CPUs in the S5-135U/155U PLC. The four memory pages serve
for the exchange of data blocks between CPUs.
Please consult the Programming Guides of the CPUs to program these two
functions.

Addressing method for the page memory (vector register)
The vector register serves to form subaddresses of several memories in a
common address area. The register is an 8-bit register which is written to
under address FEFFH. It cannot be read out.
The page memory contains four pages of 1 Kbyte. An identification number
is assigned to each page. These are the numbers 252, 253, 254 and 255.
These numbers are permanently set on the COR 923C and cannot be
changed. You must not use these numbers on other modules (CP, IP) in the
same PLC otherwise double addressing will occur.
When the supply voltage is switched on, the vector register is cleared. The
vector register then has the number 0H.
The transfer of data to and from this memory is implemented with special
functions of the CPU. You can find these functions in the appropriate
Programming Guides.
The PG interface of the COR 923C can be switched over to eight different
serial interfaces via the path selection of the PG software.
The multiplex interfaces have TTL level and are wired to the other modules
via the backplane connector and backplane.

DIL switch S2 in binary code. The maximum of eight numbers are allocated
to the slots of the PLC (see following table).
All eight numbers or slots are assigned to switch S3: the lowest number to
switch S3.1, and the highest number to switch S3.8. The setting of station

Interface Modules
Various interface modules (IMs) are available for communication between a
central controller and expansion units, and between expansion units.
Interface modules in the central controller are known as EU interface
modules; those inserted in an EU are known as CC interface modules.
This chapter describes the EU interface modules:
IM 300-3, IM 300-5, IM 301-3, IM 301-5 and IM 304
as well as the CC interface modules:
IM 312-3, IM 312-5, IM 310 and IM 314
Other IMs such as the IM 307-IM 317 and the IM 308-IM 318 are described
in separate manuals (see Catalog ST 54.1). The IM 306 CC interface module
is described in the S5-115U PLC manual.
A general overview of the applications of individual IMs can be found in
Chapter 2: “Centralized and Distributed Configuration of a Programmable
Controller.”

7.1 The 300 and 312 Interface Modules
The 300 and 312 interface modules are used for centralized connection of
I/O modules and signal preprocessing modules (IPs) to a CC via the
following expansion units (allowing for possible configurations):
EU 183U
EU 184U
EU 185U (only input/output modules)
EU 187U
ER 701-1
Additionally, you can utilize these IMs for secondary communication, i.e.
additional EUs can be connected in a centralized arrangement to an EU 183U
or EU 185U in distributed configuration. Up to four IM 300s can be used in
one CC, up to two of which may be IM 300-5s. You can use one IM 300 in
an EU 183U or EU 185U.
An IM 300 EU interface module is complemented by an IM 312 or
IM 306 CC interface module. Use the following IMs, depending on the
connected EU:
EU Interface Module EU Type CC Interface Module
IM 300-5 C

For one IM 300-5, you can connect up to three EUs to a CC or EU in
distributed arrangement (see Figures 7-5 and 7-6). The EUs are supplied with
operating voltage via the IMs. Any free connections on the IM 300-5 and the
last IM 312-5 require no terminator.
Note
The maximum permissible current over each connection of the
IM 300-5CA11 is 5 A.
You can connect up to four EUs to each IM 300-3. The last IM 312-3
requires a terminator.
You can connect up to three ERs to each IM 300-5L (-5LB11). The ERs are
supplied with operating voltage via the IMs.
Note
The maximum permissible current over each connection of the
IM 300-5LB11 is 2 A.
The connection of central controller and expansion unit to the IM 300-5LB11
is provided exclusively by the 705-0 connecting cable. It is available in two
lengths: 0.5 m and 1.5 m (refer to the ordering information for
order numbers).
When the IM 300s are used in the S5-135U/155U PLC, the input/output
modules can be addressed in the normal (P) and extended (O) areas.
You may only set module addresses in the EU which are not used in the CC.
This applies to both areas.

7.2 The 301 and 310 Interface Modules
The IM 301 is used to connect I/O modules and signal preprocessing modules
(IPs) to a CC in a distributed arrangement (allowing for possible
configurations) via an
EU 183U
EU 185U (only input/output modules)
expansion unit.
You can connect up to four EUs to a CC in distributed arrangement via the
IM 301. If you use the 721 connecting cable, the total cable length from the
CC to the last EU may be up to 200 m. The distributed connection is made
via the lower front connector of the module. Use the IM 310 interface
module in the EU to be connected in a distributed arrangement:
EU Interface Module EU Type CC Interface Module
IM 301 EU 183U,
EU 185U
(only I/O modules)
IM 310
Apart from the distributed EUs, you can connect the following expansion
units in a centralized arrangement:
EU 183U
EU 184U
EU 187U
The centralized connection is made via the upper front connector of the
module. Use the following interface modules, according to the EU to be
connected in a centralized arrangement:
EU Interface Module EU Type CC Interface Module
IM 301-5 EU 184U, EU 187U IM 312-5
IM 301-3 EU 183U IM 312-3
Unused centralized connections of the IM 301-3 and unused distributed
connections of the IM 301-3 and IM 301-5 must be terminated with
terminators. The same applies to the last IM 310.
You may only set module addresses in the EU which you are not yet using in
the CC. This applies to the normal (P) and extended (O) areas.

7.3 The 304 and 314 Interface Modules
The IM 304 and IM 314 are used to connect I/O modules, signal
preprocessing modules (IPs) and communication processors (CPs) to a CC in
a distributed arrangement via the
EU 185U
ER 701-3
expansion units.
You can also use the IM 304 and IM 314 to connect I/O modules to a CC in a
distributed arrangement via the
EU 183U
ER 701-2
expansion units.
You can connect up to two-times four EUs in a distributed arrangement via
one IM 304. If you utilize the 721 connecting cable, the total line length from
the CC to the last EU may be 600 m per run. You can connect additional EUs
in a centralized arrangement to the distributed EUs.
You can insert up to four IM 304s in one CC.
The IM 304 EU interface module is complemented by the
IM 314 CC interface module. In fault-tolerant systems, you must use the
IM 314R CC interface module together with the IM 304 (refer to the
S5-155H manual).

Digital input and digital output modules are I/O modules which allow the
processing of widely differing process signals with the S5-135U/155U
programmable controller. They can also be used via an adapter casing in the
S5-115U PLC.

A digital input module converts the process signals to the internal signal
level in the module. Interference is suppressed by the input circuitry, and the
logic states at the inputs are indicated with LEDs on the front strip of the
module. With most digital input modules (except the 420), the signals are
isolated from the central ground point when received. Inputs relating to the
same group are isolated from inputs of another group, but not from each
other.
The control signals processed in the PLC are output via digital output
modules at a signal level suitable for the actuator, for example contactor,
solenoid valve, etc. For the voltages and currents required in the process,
modules with appropriate output circuitry are available.
With most digital output modules (except the 441), the signals are isolated
from the central ground point when relayed to the outputs. Outputs relating to
the same group are isolated from outputs of another group, but not from each
other.
If a digital output module receives a “command output inhibit” (BASP, cf.
Programming Guide and Chapter 4) from the CPU, the outputs are set to
zero.
When the supply voltage of the central controller or expansion unit has been
switched on or when the CPU is at STOP, the outputs are set to zero.
Signal output H+ on digital output modules for direct voltage emits a signal
when a short-circuit to ground (L-) or overcurrent has been detected at one or
more outputs currently at logic 1. Only short-circuits which are effective for
more than 0.5 to 1 s are detected. Short-circuits are only detected at
connected outputs. The signal outputs are decoupled by diodes. Up to
16 outputs can be connected in parallel. Ensure that isolation is not defeated
by the parallel connection of outputs.
To ensure functioning of the signal output, you must connect terminal 1L+ to
24 V on the 441, 451 and 454 modules. On the 453 and 457 modules, the
floating signal output must be powered separately.

8.1.1 Design
The modules are designed as plug-in PCBs for central controllers and
expansion units with backplane connector and with a blade connector to
accept a plug-in front connector. The front connector has screw or crimp
terminals and is available separately; you can connect the process signal lines
to it directly.
Fitted to each module is a strip with green LEDs to indicate the logic states
of inputs or outputs. The LEDs are arranged in bytes and marked bit 0 to 7.
Output modules for direct voltage additionally have red LEDs to indicate
short-circuits between output lines and ground (L-) within a group. Output
modules for alternating voltage have red LEDs to indicate a fuse failure.
Fitted on each module is an addressing switch with six, seven or eight
rockers to set the module address.
The modules are protected on both sides by covers.

8.1.2 Function of the Enable Inputs
The digital input/output modules have an enable circuit. You can use the
enable inputs to implement electrical interlocks for certain modules or switch
off individual modules, whilst the PLC is in operation.
This means that:
the module can no longer be addressed by the user program.
all outputs of digital output modules are set to zero.
Modules which are switched off can be removed or inserted during operation.
If this is not necessary, operate the module with the enable input switched
off.
On digital input/output modules with DC voltage inputs or outputs, the
enable circuit requires that enable inputs F+ and F- be wired in the front
connector. Enabling is achieved by applying an external voltage to inputs
F+/F-. Modules for AC voltage have a wire jumper in the front connector.
When the front connector is swivelled away from the front strip of the
module, the supply of power to the enable input is interrupted, i.e. the wire
jumper in the front connector is removed; the module is switched off and can
no longer be addressed by the user program.
When the front connector is swivelled away, i.e. the voltage is removed from
the enable inputs, a timeout (QVZ) occurs at the CPU (see the Programming
Guide for the particular CPU).
Apart from the 6ES5 458-4UC11 digital output module, all digital
input/output modules additionally offer the facility for changing the enable
mode. The modules have a jumper accessible from above in the vicinity of
the addressing switch (see Figure 8-2).

8-6 System Manual
C79000-G8576-C199-07
If removal and insertion of modules during operation is not required, you
must remove the plug-in jumper for changeover of the enable mode. Wiring
of the enable inputs (F+/F-) can then be dispensed with.
Almost power-free shutdown of individual subprocesses, i.e. outputs of
various modules can be operated from a common load supply and yet
activated separately.
The load voltage of each individual module can be monitored without
additional circuitry. Any reactions to failure of the load voltage can be
programmed in the QVZ (timeout) organization block.
You must observe the following when configuring systems:
Switching on At the latest 100 ms after power-up of the PLC, the voltage must be
present at the enable inputs of the I/O modules.
Switching off When the PLC has been switched off, the voltage at the enable
inputs of the I/O modules must still be present as long as voltage is
applied to the CC/EU.
You should observe the following instructions for switching off PLCs and
equipment for supplying power to the enable inputs:

When there is a need to switch off the load power supply separately without
affecting the enabling of modules, there are the following possibilities for
producing the enable voltage. These exist even when the power supply is

8.1.3 Special Features of the 432 Digital Input Module
The 432 digital input module accepts 32 process signals and emits a process
alarm if the logic state at one of its inputs changes.
You can operate the module in the following modes:
without process alarm (“normal” digital input module)
with initiation of a process alarm via interrupt
with initiation of a process alarm via IB 0 (only in conjunction with
CPU 948)
To operate the module with process alarm via IB 0, you must address it in the
normal (P) area from byte 128 because
the automatic updating of the process image might acknowledge a process
alarm without the system program having detected and interpreted this
alarm;
only modules addressed in the normal (P) area can initiate a process
alarm via IB 0.
The time for reaction of the module to a process alarm is mainly determined
by the input circuitry. You can set the reaction time to one of the values
0.3 ms, 1 ms or 3 ms with switch S5. Note that the filtering effect decreases
with shorter reaction times, and interference may be received as useful
signals (effect of the line length, see the Technical Specifications).
To operate the module without process alarm, you can insert it at any slot for
I/O modules and address it in the entire I/O area. If you address it in the
area PB/PY 0 to PB/PY 124, it will be within the automatic updating of the
process image.

alarm:

System Manual
C79000-G8576-C199-07
To operate the 432 digital input module with process alarm via an interrupt,
you must either operate it in the CC where only certain slots have interrupt
lines (see Chapter 4), or in an interrupt-capable EU connected to the CC with
IM 307 - IM 317 interfacing (see also the IM 307 - IM 317 manual). In the
CC, you may only operate the module in this mode at slots with an interrupt
line (interrupt source).
So that the module can initiate a process alarm for a change of logic state, the
alarm must be processed by an alarm routine (alarm OB) in the user program,
with automatic acknowledgement of the alarm. To avoid loss of an alarm, it
must not be possible for the alarm OB to be interrupted by process alarms.
The CPU must process the process alarms with level triggering (see
Programming Guide of the CPU).
Example:
Program the following operations in the corresponding alarm OB:
L PW132 (load I/O word)
T FW10 (transfer flag word)
L PW134 etc.
T FW12
Only the flag word may be accessed during the cyclic program.
Accessing the I/O bytes in the process image will result in alarm loss.
Addressing of the module must therefore be above address 127. Double
accessing of I/O bytes, even from different CPUs, is not permissible (alarm
loss).
The four I/O bytes of a module must be scanned successively and in
ascending order. The scanning of byte n inhibits all input circuits of the
module, and the scanning of byte (n + 3) enables them again.
Make the following settings on the module to operate it with a process alarm
via interrupt:
Step Action
1Open jumper X4 and close jumper X3.
2Set the interrupt line at switch row S1: the switch relating to the
desired interrupt line should be set to On. Set all other switches
to Off. You can set the same interrupt line on several modules.
3Set switch row S2 to Off.
4Set switch row S3 to choose whether the interrupt is to be
initiated with a positive-going (leading) or negative-going
(trailing) edge. The setting of a pair of switches applies to an
entire byte.

In this mode, a process alarm is initiated via input byte IB 0. This mode is
only possible in conjunction with a CPU 948 in single-processor operation.
To operate the 432 digital input module with process alarm via IB 0, you can
insert it at any I/O slot.
When you use the module in the CC, you must not set any other input
module to address 0 (i.e. neither in the normal (P) nor in the extended (O)
area).
If you use the module in an EU which is addressed in the normal area, you
must not set any other input module in the EU to address 0 in the normal
area.
So that the module can initiate a process alarm for a change of logic state, the
alarm must be processed by an alarm routine (alarm OB) in the user program,
with automatic acknowledgement of the alarm. To avoid loss of an alarm, it
must not be possible for the alarm OB to be interrupted by process alarms.
The CPU must process the process alarms with level triggering (see
Programming Guide of the CPU).

You can use up to eight 432 digital input modules with process alarm via
IB 0 in one PLC. The modules must all be inserted in the CC or in the same
EU for error-free acknowledgement of address 0. Each module reserves one
bit in IB 0. You must set one module to bit 0 on switch row S2; on the other
modules you must remove jumper X3 and set one of the other bits 2 to 8.
The module you have set to bit 0 is known as the master, and the other
modules are slaves. On the master module, you must additionally set the
number of slave modules on switch row S2. Refer to the labeling on the
module cover.
You can also use the 432 digital input module with process alarm together
with other alarm-generating modules.
To operate the module with process alarm via interrupt, you must observe the
following:
If a process alarm is generated via an interrupt, the I/O words of all
432 digital input modules involved in this process alarm must be read in
the alarm-processing OB; with IPs, the process alarms must be
acknowledged (refer to the manuals of the IPs).
The modules must be inserted at interrupt-capable slots (see Chapter 4).
To operate the module with process alarm via IB 0, you must observe the
following:
You may use up to eight alarm-generating modules.
The modules must all be inserted in the CC or all in the same EU.
You must operate the 432 module as the master. If you use two or more
432 digital input modules with other alarm-generating modules, you must
operate one 432 as the master and all others as slaves.
8.1.4 Special Features of the DI/DQ 482
The DI/DQ 482 digital input/output module (6ES5482-4UA11) is a process
signal I/O module which allows the processing of process signals in
conjunction with the IP 257, with the S5-135U/155U PLC and the EU 185U
(see the IP 257 manual). The DI/DQ 482 (6ES5482-4UA20) has an identical
functionality, but not an interface which allows a connection to the IP257.
The following section describes the operation of the DI/DQ 482 without
IP 257.
The DI/DQ 482 has 32 channels which are jointly isolated, i.e. there is no
subdivision into groups in the module. Channels 0.0 to 0.7 are digital outputs,
channels 2.0 to 3.7 are digital inputs; channels 1.0 to 1.7 can be optionally
and individually operated as inputs or outputs.

System Manual
C79000-G8576-C199-07
The operation of channels 1.0 to 1.7 as inputs or outputs merely depends on
the user program. You define the byte as an input with a read access to the
DI/DQ; you define the byte as an output with a write access. The
double-function of the byte also allows the output byte to be read out.
Unused channels should not be wired nor addressed by program. When these
channels are used as inputs, it should be noted that the corresponding bits in
the output register remain at logic 0. This resetting of output registers is
executed automatically after power-up of the PLC or EU.
Note
When at least one of channels 1.0 to 1.7 is operated as an input, the
connected sensors and the 1L+ terminal must have the same power supply. If
this is not the case, the input voltage acts on the 1L+ terminal. The resultant
supply to the output amplifiers of channels 0.0 to 1.7 causes currents to be
drawn via the wired input terminal; these currents may assume different
values, depending on the control states of the outputs.
With the DI/DQ 482 (6ES5482-4UA11) you must set slide switch S2 to
setting 1 for operation without the IP 257.

8.2 Installation and Startup
This section describes how to prepare digital input/output modules for
installation, and how to install and wire them.
8.2.1 Setting the Module Address
You set the module address on the addressing switch. This also establishes
the necessary assignments between user program and process connection.
The address of the digital input modules (input bytes IB 0 to 255 or 252 for
the DI/DQ 482) and digital output modules (output bytes QB 0 to 255 or 252
for the DI/DQ 482) is the sum of the binary significances established by
depressing the individual rockers in the On setting ().
The modules are addressed by the STEP 5 program under their parameters
(byte address).
You can affix the adhesive label with the desired module address on a
labeling field under the addressing switch. Suitable labels are supplied with
the CC.
The switch rockers with which the module address (IB n or QB n) is
specified as a decimal number, are marked by dots on the label.
Do not use a pencil to set the addressing switch.

The address byte under which the module is referenced by the
STEP 5 program is independent of the slot.
For modules with 16 or 32 inputs or outputs, i.e. 2 or 4 bytes, only the lowest
address (start address) is set for the first byte. The addresses of the following
bytes of the same module are decoded on the module.
If, for example, the address 20 is set for a 16-bit module (2 bytes), the
following address 21 is decoded internally and is no longer available. The
next free address would be 22.
For a 32-bit module (4 bytes) with start address 20, addresses 21, 22 and 23
would be decoded internally. The next free address would be 24.
Addresses already assigned must not be set again.
However, digital input and output modules may be given the same address
because they are referenced by different commands in the user program.

8.2.2 Removing and Inserting Modules
!Warning
When removing and inserting the front connector during operation,
hazardous voltages of more than 25 V AC or 60 V DC may be present at the
module pins. When this is the case at the front connector, live modules may
only be replaced by electrical specialists or trained personnel in such a way
that the module pins are not touched. During operation, the front connector
and module must not be removed or inserted without the enable jumper or
active enable circuit.
Install a digital input/output module as follows:
Step Action
1Release the upper locking bar on the subrack and swivel it
upwards and out.
2Insert the module at the desired slot in the subrack and push it
back in the guides.
3Latch the module by rotating the locking pin by 90° at the
lower end of the module.
4Engage the front connector on the support pin of the module
and swivel it up. The width of the support pin also provides
keying to prevent front connectors from being fitted to the
wrong modules (for example 230 V AC front connector on
24 V DC modules).
5Tighten the screw in the upper part of the front connector.

Remove a digital input/output module as follows:
Step Action
1Release the upper locking bar on the subrack and swivel it
upwards and out.
2Slacken the screw in the upper part of the front connector.
This causes the front connector to be pressed out of the female
connector of the module. Contacts F+ and F- of the enable
input at the upper end of the front connector are thus opened
first.
3Swing the front connector out and lift it away from the support
pin of the module.
4Release the module, if necessary, by rotating the locking pin by
90o. You can pull the module out of the subrack with a grip
which swivels outwards.

8.2.4 Connecting the Signal Lines
The modules have 20 or 42-pin blade connectors with contact blades
measuring 2.4 x 0.8 mm. Front connectors for 20 and 40 mm mounting width
with crimp connection and 40 mm mounting width with screw connection are
provided to connect the signal lines (screwdriver blade width: 3.5 mm,
maximum torque: 0.8 Nm).
Use stranded conductors to facilitate handling of the front connector.
When the crimp contact is inserted in the plastic body of the front connector,
a click can clearly be heard. This indicates that the contact is engaged. For
jumpering or to correct the wiring, you can remove the contacts with a
releasing tool (see Ordering Information) without having to pull out the front
connector.
Ferrules are not required for screw connections, because the screw terminals
are provided with wire protection. You can use ferrules of 7 mm in length
according to DIN 46228. The maximum terminal area is 2 x 2.5 mm2.

With isolated modules, the inputs or outputs can be fed from two separate
power supply units in isolation groups created by the internal distribution in
the module.
Note that when inputs or outputs from two isolated groups are connected to
one power supply unit, isolation between the groups is defeated.
8.2.6 Short-Circuit Protection and Fusing
With digital output modules for DC voltage, fuses are provided on the
module, in addition to the electronic short-circuit protection, for the wiring
cables and to protect the module. The fuses also provide protection against
reversal of supply voltage connections and can only be replaced at the
factory.
The electronic short-circuit protection guaranteed in the technical
specifications applies to a resistance which is lower than the specified,
maximum permissible line resistance.
In the event of a short-circuit, two to three-times the rated output current
flows briefly at the output before the switched electronic short-circuit
protection becomes effective. When selecting the load power supply units,
therefore, allow for the increased short-circuit current as well as all
connected output loads (observe the coincidence factor). With unregulated
load power supplies, this overcurrent is generally ensured. With regulated
load power supplies, especially at low output power levels (up to 20 A), you
must allow for a corresponding overcurrent.

8.2.7 Quenching for Inductive Loads
Note
Digital output modules have integrated circuits on the module to quench
inductive loads (refer to the technical specifications of the output modules).
Exception: The 458 digital output module allows the switching of inductive
loads with contact protection submodules.
The integrated circuits on the modules for quenching inductive loads are
disabled if the load circuits are interrupted, either
operationally by contacts and switches,
or by fuses in the event of a fault.
This can result in excessive, inductive breaking voltages which put fault-free
operation at risk.
You can prevent this with additional, external quenching circuitry for the
inductive loads.

External quenching circuitry is needed when
the switching frequency of an output is greater than that specified in the
technical specifications (thermal stress of the integrated circuit for
quenching inductive loads);
disconnection of output lines can be expected;
disconnection of the supply line can be expected.
When selecting or designing the quenching circuitry, the technical
specifications for the digital output should be taken into account. These are:
The permissible overvoltage for the supply voltage (see Section 8.3
“Common Technical Specifications”)
Inductive breaking voltage of the output (see Section 8.4 “Description of
Individual Modules”)
An external quenching circuit only provides thermal relief if its quenching
voltage is lower than the breaking voltage specified for the module, allowing
for unfavorable supply voltage conditions.
Example: 453 digital output
Inductive breaking voltage L+ - 47 V (Tech. Specifications)
Max. supply voltage L+ = 30 V
Quenching voltage referred to L- (0 V ground) is - 17 V
The quenching device must be rated at approximately 15 V and the switched
load current, for example, 1 A.
A quenching device rated for the induced breaking current must be provided
at the load (see Figure 8-14).
The quenching voltage at the load is independent of the module. The
quenching devices must also ensure that the overvoltages at the switch and in
the wiring do not exceed the disturbance voltage and voltage hazard limits
permissible to VDE/IEC.
The following applies to digital outputs for DC voltage:
In general, load power supplies should be switched on the primary side to
utilize the low-resistance secondary winding and smoothing capacitors of the
power supply for energy compensation in the dropping of inductive loads.
The load power supply switch should only be considered as a circuit breaker.
With switched-through digital outputs and disconnection of the
supply line L+, the output current is maintained during the quenching time
by capacitors and the reverse voltage protection diode on the module. This
severe electrical stress of the module should be avoided during operations,
because it can result in a fault in the long term.

With two-wire switches and AC voltage outputs:
Disconnection of the supply voltage during operation is not permissible
without additional protective circuitry. Quenching of the inductive load is
achieved here via the load power supply unit or system. Since, as two-wire
switches, the outputs have no L-/N (0 V ground) terminal, the inductive load
cannot be quenched on the module when the supply line is disconnected.
With the 453 and 457 modules using two-wire switches, the overvoltages can
result in destruction of the module.
If the load voltage must be switched for safety reasons, you must provide
external quenching circuitry at each inductive load (see Figure 8-15).
Instead, with the 453 and 457 modules using two-wire switches, you can
insert a quenching device (diode) with adequate ratings after contact K from
the L+ line to L-.

Analog input and analog output modules are I/O modules for the input/output
of widely differing, analog process signals for the
S5-135U/155U programmable (logic) controller.
These I/O modules allow the creation of control systems which require the
processing of analog measured variables or continuous input to actuators.

9.3 The 460 Analog Input Module
9.3.1 Design
The modules are designed as plug-in PCBs for central controllers and
expansion units with a backplane connector and with a blade connector to
accept a plug-in front connector. You can directly connect the process signal
lines to the front connector, which is available separately, with screw or
crimp terminals.
Situated on each module is an addressing switch with six rockers to set the
module address. Analog input modules also have two switches on the side
with eight rockers for setting the mode, and receptacles for range cards.
The modules are protected by covers on both sides.

9.3.2 Function of the Enable Input
The 460 module has an enable circuit. You can use the enable inputs to
switch off individual modules whilst the PLC is in operation. This means
that:
The module can no longer be addressed by the user program.
Modules which are switched off can be removed or inserted during operation.
If this is not necessary, operate the module with the enable input switched
off.

System Manual

The enable circuit requires an external 24 V voltage at enable inputs F+/F- in
the front connector. If there is no voltage at F+/F-, the modules will not
acknowledge.
When the front connector is swivelled away from the front strip of the
module, the supply of power to the enable input is interrupted, i.e. the
module is switched off and can no longer be addressed by the user program: a
timeout (QVZ) occurs in the CC.
The 460 module additionally offers the facility for changing the enable
mode. The module has a jumper accessible from above in the vicinity of the
addressing switch.
When the enable jumper is inserted, you can define the behaviour of the
460 analog input module as follows:
When the enable voltage and load voltage are obtained from the same
load supply, a shutdown of the 24 V load voltage will result in a timeout.
When the enable voltage and load voltage are obtained from different
load supplies, a shutdown of the 24 V load voltage will not result in a
timeout. (With the 460-4UA11/12 modules, a shutdown of the load
voltage will result in a timeout.)
Enable Jumper
Figure 9-2 Enable Input and Enable Jumper
Jumper inserted: Enable input (F+/F-) active (factory setting)
Jumper open: Enable input (F+/F-) switched off
Examples of functioning of the enable inputs:
To switch off individual subprocesses, i.e. outputs of various modules can
be operated from a common load supply and yet activated separately.
The load voltage of individual modules can be monitored without
additional circuitry. Any reactions to failure of the load voltage can be
programmed in the QVZ (timeout) organization block.

You must observe the following when configuring systems:
Switching on At the latest 100 ms after power-up of the PLC, the voltage
must be present at the enable inputs of the I/O modules.
Switching off When the PLC has been switched off, the voltage at the
enable inputs of the I/O modules must still be present as
long as the internal 5 V voltage is present.
You should observe the following instructions for switching off CCs and
equipment for supplying power to the enable inputs.
When there is a need to switch off the load power supply separately without
affecting the enabling of modules, there are the following possibilities for
producing the enable voltage. These exist even when the load power supply
is used without an additional capacitor and common shutdown.

input signals; periodic system interference is thus suppressed.
You can adapt the process signals, according to the application, to the input
level of the analog-to-digital converter of the module with plug-in range
cards (resistor dividers or shunt resistors).
To monitor the sensors connected to the inputs, you can use the
6ES5 498-1AA11 range card (through-connection card) to implement the
“broken wire detection” mode. You can activate broken wire detection for
4 or 8 inputs.
Each time the input value is about to be encoded, a constant current is briefly
(1.6 ms) switched to the input terminals and the resultant current is checked
for a limit value. If a digital voltmeter is used to measure the signal at the
input, these current pulses may appear to indicate fluctuation of the signal.
The encoded value, however, is not affected.
If these apparent fluctuations of the signal are disturbing, for example, during
startup, you can switch the tripping current to the inactive state on the 460
analog input module: apply + 24 V to pin 24 of the front connector,
and 0 V to L-. You must additionally set the mode switch to “without broken
wire detection.”
In the event of open-circuit of the sensor or its line, the voltage exceeds the
limit and a broken wire is indicated (bit 1 in data byte 1). The
analog-to-digital converter encodes the value 0.
A broken wire signal is only useful when the 6ES5 498-1AA11
through-connection card is used. With all other measurement cards, a broken
wire signal will result in incorrect reactions. Further details relating to the
broken wire signal can be found in Section 9.3.12.
If the measuring range is exceeded, the overflow bit (bit 20 of the low byte)
is set.
You have a choice of the cyclic sampling and selective sampling modes.
In the cyclic sampling mode, the module continuously encodes all measured
values. The digitized measured values are stored under the channel-related
address on the module (the high byte under this address, and the low byte
under the next higher address). The measured values can then be read by the
module at any time without waiting. When you operate the module in this
mode, you can set a module address from 0 to 255.

System Manual
C79000-G8576-C199-07
In the selective sampling mode, a measured value is encoded on the central
initiative of the CPU. At the start of conversion, the module must be
addressed once with a write operation (T PW) by the user program. An active
bit (T = 1) is set during encoding.
With the transition to T = 0, the measured value becomes valid. With
non-constant cycle times, there may be non-periodic measured value
aquisition. If you operate the module in this mode, you must set a module
address from 128 to 255. You can also use the address range from 0 to 127
for selective sampling after appropriate programming in DB 1 of the user
program.
Another method is that of time-controlled program processing. With this
method, certain program segments (e.g. FB 13) are automatically inserted
into program processing at the 100 ms rate by a time-controlled block
(OB 13). A constant timebase is thus achieved.

9.3.4 Setting the Module Address
You set the module address on the addressing switch. This also establishes
the necessary assignments between user program and process connection.
The module address is the sum of the decimal significances of the switch
rockers in the On setting ().
One data word = two data bytes is required to process an input or an output.
A module with 16 inputs therefore reserves 32 byte addresses, and a module
with 8 inputs or outputs reserves 16 byte addresses.
You can affix the adhesive label with the desired module address on a free
labeling field under the addressing switch.
The switch rockers to be set for the module address specified as a decimal
number (address bit ADB) are marked by dots on the label.
Press the individual rockers of the addressing switch downwards with a
ballpoint pen or similar object, but not a pencil.
Note
Ensure that all the switches are operated properly (meaning pressed past the
latching point).

The address under which the module is referenced by the STEP 5 program is
independent of the slot.
For analog input and analog output modules (8 inputs) only the lowest
address (start address) is set. Other addresses (subaddresses) are decoded on
the module.
Note
The start address of the analog module must be a multiple of the double
channel number.
4 channels : 0, 8, 16, 24, ... 248
8 channels : 0, 16, 32, 48, ... 240
If one of the inputs or outputs (Channel 0 to 7) of a module is to be
addressed, the relevant subaddress must be specified in the program.
The subaddress of the input or output, based on the start address of the
module, is given by:
Start address + 2 x channel no. = subaddress
Example:
Analog input module with 8 inputs
The address is the sum of the significances set with the individual coding
switches.

However, analog input modules and analog output modules may be given the
same address with cyclic sampling because they are distinguished by the user
program. This is not possible with selective sampling.
For cyclic sampling, you can address the module in the address range from
0 to 255, and for selective sampling from 128 to 255. For selective sampling,
you can also use the address range from 0 to 127 after appropriate
programming in DB 1 of the user program.
Example:
On an analog input module with start address 160 (IB 160 = input byte 160),
input channel 3 is to be scanned by the program.
Step Action
1Affix the self-adhesive label with address 160 on the free field under the
addressing switch on the module. ADB 5 and ADB 7 are marked on the
label.
2Press the appropriate rockers of the addressing switch down on the side
marked by a dot on the module cover. Set the other rockers to the opposite
setting. This way sets the start address of the module.
ADB 5 and ADB 7 results in 25 + 27 = 32 + 128 = 160
3Enter the address 160 + 3 x 2 = 166 in the program for input channel 3.

9.3.5 Removing and Inserting Modules
!Warning
When removing and inserting the front connector during operation,
hazardous voltages of more than 25 V AC or 60 V DC may be present at the
module pins. When this is the case at the front connector, live modules may
only be replaced by electrical specialists or trained personnel in such a way
that the module pins are not touched.
During operation, the front connector and module must not be removed or
inserted without the enable jumper or active enable circuit.
Install an analog input/output module as follows:
Step Action
1Release the upper locking bar on the subrack and swivel it upwards and
out.
2Insert the module at the desired slot in the subrack and push it back in the
guides.
3Latch the module by rotating the locking pin by 90o at the lower end of
the module. It must no longer be possible to pull the module forwards.
4Engage the front connector on the support pin of the module.
The width of the support pin also provides keying to prevent front
connectors from being fitted to the wrong modules (e.g. front connectors
with 115/230 V AC wiring cannot be plugged into analog modules).
5Tighten the screw in the upper part of the front connector.

Remove an analog input/output module as follows:
Step Action
1Release the upper locking bar on the subrack and swivel it upwards and
out.
2Slacken the screw in the upper part of the front connector. This causes the
front connector to be pressed out of the female connector of the module.
Contacts F+ and F- of the enable input at the upper end of the front
connector are thus opened first. If the enable input is active, power is
removed from the outputs and the module is isolated from the S5 bus.
3Swing the front connector out and lift it away from the support pin of the
module.
4Release the module by rotating the locking pin by 90o at the lower end of
the module. You can pull the module out of the subrack with a grip with
swivels outwards.

9.3.7 Connecting the Signal Lines
For connection of the signal lines, front connectors for 20 and 40 mm
mounting width with crimp connection and 40 mm mounting width with
screw connection are available (screwdriver blade width: 3.5 mm, maximum
torque: 0.8 Nm).
Use stranded conductor to facilitate handling of the front connector. Ferrules
are not required for screw connections, because the screw terminals are
provided with wire protection.
When the crimp contact is inserted in the plastic body of the front connector,
a click can clearly be heard. This indicates that the contact is engaged. For
jumpering or to correct the wiring, you can remove the contacts with a
releasing tool (see Ordering Information) without having to pull out the front
connector.
Ferrules are not required for screw connections, because the screw terminals
are provided with wire protection. You can use ferrules of 7 mm in length to
DIN 46228. The maximum terminal area is 2 x 2.5 mm2.

9.3.9 Connecting a Compensating Box for Thermal
E.M.F. Measurement
If the room temperature fluctuations at the reference point (for example, in
the terminal box) affect the measurement result and you do not wish to use a
thermostat, you can compensate for the effect of temperature on the reference
point with a compensating box. Between - 10 and + 70 oC, it compensates for
the change in thermal e.m.f. caused by temperature deviation (compensating
box, see Catalog MP 19). Ensure that the compensating box has thermal
contact with the terminals.
If the compensating box is aligned at 20 oC, this must be taken into account
in temperature evaluation (20 oC measuring point temperature = 0 mV).
Pins 22 and 23 are extended on analog input modules as an input for the
compensating voltage. You must select a common input loop for all inputs on
mode switch 2.
The compensating box must be connected in a floating circuit. The power
supply unit of the compensating box must have a grounded shield winding to
avoid AC system interference being picked up. A separate compensating box
with its special power supply unit is required for each analog input module.

When Pt 100 resistance thermometers are connected, the maximum
temperature in the rated range is 266 oC. If it can be ensured that the
temperature does not exceed 850 oC, the input value may extend into the
overrange. The resolution is then 4095 units. Unused inputs can be utilized
for voltage measurements in the 500 mV range (see front connector
assignments).
In addition to the standard Pt 100 range, there is an extended Pt 100 range on
the 460 analog input module. You can select this with the mode switch.
The following is printed on the cover of the module to set the Pt 100 mode:
Standard range: “resistance thermometer uncompensated full range”
Extended range: “resistance thermometer compensated low range”
In this range, the basic resistance of the Pt 100 at 0 oC (100 ohm) is
compensated for on the module. As in the standard range, the Pt 100 is fed
with a constant current of 2.5 mA. Using the overrange (- 100 mV to
+ 100 mV), this results in a temperature range of approx. -100 °C to
+ 100 °C.
This measuring range of 200 °C is resolved to 8192 units with the correct
sign for the temperature. One unit thus corresponds to approximately
0.025 °C. If you select the extended Pt 100 range, you can use all
8 analog inputs in this range only.
You should only use the 6ES5 498-1AA11 range card ( 50 mV/500 mV).

Measuring range 500 mV; card with 31.25 ohm shunt
(6ES5 498-1AA51/AA71)
The 4 to 20 mA range is resolved to 2048 units at an interval of 512 to 2560.
If you require a representation from 0 to 2048, you must subtract 512 units by
software. Please note the following:
A broken wire signal cannot be emitted.
Detection of the overrange can be achieved by scanning bits 29 and 211.
A broken wire can be detected with currents < 3 mA.
If you short-circuit the positive and negative terminals of the transducer
when using the 6ES5 498-1AA51 range card (for a two-wire transducer),
the current is limited to about 28 mA. Until the thermal current limiting
circuit responds in the range card (about 3 s), a short-circuit current of
approximately 250 mA flows; this sets the overflow bit for this duration
at all channels.

9.4 The 463 Analog Input Module
9.4.1 Design
The modules are designed as plug-in PCBs for central controllers and
expansion units with a backplane connector and with a blade connector to
accept a plug-in front connector. You can directly connect the process signal
lines to the front connector, which is available separately, with screw or
crimp terminals.
Situated on each module is an addressing switch with six rockers to set the
module address. Analog input modules also have two switches on the side
with eight rockers for setting the mode, and receptacles for range cards.
The modules are protected by covers on both sides.

9.4.2 Function of the Enable Input
The 463 module has an enable circuit. You can use the enable inputs to
switch off individual modules whilst the PLC is in operation. This means
that:
The module can no longer be addressed by the user program.
Modules which are switched off can be removed or inserted during operation.
If this is not necessary, operate the module with the enable input switched
off.

The enable circuit requires an external 24 V voltage at enable inputs F+/F- in
the front connector. If there is no voltage at F+/F-, the modules will not
acknowledge.
When the front connector is swivelled away from the front strip of the
module, the supply of power to the enable input is interrupted, i.e. the
module is switched off and can no longer be addressed by the user program: a
timeout (QVZ) occurs in the CC.
The -4Ux12 type modules additionally offer the facility for changing the
enable mode. The modules have a jumper accessible from above in the
vicinity of the addressing switch.
Enable Jumper
Figure 9-13 Enable Input and Enable Jumper
Jumper inserted: Enable input (F+/F-) active (factory setting)
Jumper open: Enable input (F+/F-) switched off
Examples of functioning of the enable inputs:
To switch off individual subprocesses, i.e. outputs of various modules can
be operated from a common load supply and yet activated separately.
The load voltage of individual modules can be monitored without
additional circuitry. Any reactions to failure of the load voltage can be
programmed in the QVZ (timeout) organization block.

You must observe the following when configuring systems:
Switching on At the latest 100 ms after power-up of the PLC, the voltage
must be present at the enable inputs of the I/O modules.
Switching off When the PLC has been switched off, the voltage at the
enable inputs of the I/O modules must still be present as
long as the internal 5 V voltage is present.
You should observe the following instructions for switching off CCs and
equipment for supplying power to the enable inputs.
When there is a need to switch off the load power supply separately without
affecting the enabling of modules, there are the following possibilities for
producing the enable voltage. These exist even when the load power supply
is used without an additional capacitor and common shutdown.

9.4.3 Special Features of the 463 Analog Input Module
The 463 analog input module executes integrating processing of the digital
input signals; periodic system interference is thus suppressed.
The module 463-4UA12 is suitable for operation near 50 Hz systems, the
module 463-4UA12 is suitable for operation near 60 Hz systems.
In the subsequent module 463-UA13 the system frequency can be set by
switch.
The measuring range for each channel is adapted by appropriately connecting
the sensors and with jumpers in the front connector of the module (see the
front connector assignments).
Note
The ohmic resistance of the jumper with which the measuring range is set is
also measured. As the resistance of this jumper is not inconsiderable (0.5 to
0.7 ohm in relation to the measuring shunt of 50 ohm) when I/O module
cables with integral connectors and subsequent wiring blocks are used, the
measurement result may be corrupted accordingly.
9.4.4 Setting the Module Address
You set the module address on the addressing switch. This also establishes
the necessary assignments between user program and process connection.
The module address is the sum of the decimal significances of the switch
rockers in the On setting ().
One data word = two data bytes is required to process an input or an output.
A module with 4 inputs therefore reserves 8 byte addresses.
You can affix the adhesive label with the desired module address on a free
labeling field under the addressing switch.
The switch rockers to be set for the module address specified as a decimal
number (address bit ADB) are marked by dots on the label. The unmarked
switches should be switched off.
Note
Press the individual rockers of the addressing switch downwards with a
ballpoint pen or similar object, but not a pencil. Ensure that all the switches
are operated properly (meaning pressed past the latching point).

For analog input and analog output modules (4 inputs) only the lowest
address (start address) is set. Other addresses (subaddresses) are decoded on
the module.
Note
The start address of the analog module must be a multiple of the double
channel number.
4 channels : 0, 8, 16, 24, ... 248
If one of the inputs or outputs (channel 0 to 3) of a module is to be addressed,
the relevant subaddress must be specified in the program.
The subaddress of the input or output, based on the start address of the

A module with 4 inputs (channel 0 to 3) and start address 160 reserves the
address range from
160 to address 160 + 3 x 2 = 166
In this example, the next free address for another module is 168.
Addresses already assigned must not be set again.
Example:
On an analog input module with start address 160 (IB 160 = input byte 160),
input channel 3 is to be scanned by the program.
Step Action
1 Affix the self-adhesive label with address 160 on the free field
under the addressing switch on the module. ADB 5 and ADB 7
are marked on the label.
2 Press the appropriate rockers of the addressing switch down on
the side marked by a dot on the module cover. Set the other
rockers to the opposite setting. This way sets the start address of
the module.
ADB 5 and ADB 7 results in 25 + 27 = 32 + 128 = 160
3 Enter the address 160 + 3 x 2 = 166 in the program for input

9.4.5 Removing and Inserting Modules
!Warning
When removing and inserting the front connector during operation,
hazardous voltages of more than 25 V AC or 60 V DC may be present at the
module pins. When this is the case at the front connector, live modules may
only be replaced by electrical specialists or trained personnel in such a way
that the module pins are not touched.
During operation, the front connector and module must not be removed or
inserted without the enable jumper or active enable circuit.
Install an analog input/output module as follows:
Step Action
1Release the upper locking bar on the subrack and swivel it
upwards and out.
2Insert the module at the desired slot in the subrack and push it
back in the guides.
3Latch the module by rotating the locking pin by 90o at the
lower end of the module. It must no longer be possible to pull
the module forwards.
4Engage the front connector on the support pin of the module.
The width of the support pin also provides keying to prevent
front connectors from being fitted to the wrong modules (for
example, front connectors with 115/230 V AC wiring cannot be
plugged into analog modules).
5Tighten the screw in the upper part of the front connector.

Remove an analog input/output module as follows:
Step Action
1Release the upper locking bar on the subrack and swivel it
upwards and out.
2Slacken the screw in the upper part of the front connector. This
causes the front connector to be pressed out of the female
connector of the module. Contacts F+ and F- of the enable input
at the upper end of the front connector are thus opened first. If
the enable input is active, power is removed from the outputs
and the module is isolated from the S5 bus.
3Swing the front connector out and lift it away from the support
pin of the module.
4Release the module by rotating the locking pin by 90 at the
lower end of the module. You can pull the module out of the
subrack with a grip with swivels outwards.

9.4.7 Connecting the Signal Lines
For connection of the signal lines, front connectors for 20 and 40 mm
mounting width with crimp connection and 40 mm mounting width with
screw connection are available (screwdriver blade width: 3.5 mm, maximum
torque: 0.8 Nm).
Use stranded conductor to facilitate handling of the front connector. Ferrules
are not required for screw connections, because the screw terminals are
provided with wire protection.
When the crimp contact is inserted in the plastic body of the front connector,
a click can clearly be heard. This indicates that the contact is engaged. For
jumpering or to correct the wiring, you can remove the contacts with a
releasing tool (see ordering information) without having to pull out the front
connector.
Ferrules are not required for screw connections, because the screw terminals
are provided with wire protection. You can use ferrules of 7 mm in length to
DIN 46228. The maximum terminal area is 2 x 2.5 mm2.

OV = Overflow bit
A 50 ohm shunt resistor is used for the 0 to 20 mA range; for 4 to 20 mA,
the resistor value is 62.5 ohm.
The shunt resistors are permanently fitted to the 463 analog input module.
Broken wire detection is not possible.
For the 4 to 20 mA current measuring range, a broken wire can be detected
with currents > 3 mA.
If the positive and negative terminals of the transducer are short-circuited
when two-wire transducers are used (4 to 20 mA), the current is limited to
approximately 28 mA. Until the thermal current limiting circuit responds
(about 3 s) a short-circuit current of about 250 mA flows.
The failure of the load voltage can be detected from the result of encoding
(values < -51 units).
The module 463-4UA13 does not require 24V voltage. A 24V supply is
required when connecting a 2-wire measuring transducer.

Transducers are connected to the analog input module via shielded cables of
up to 200 m in length. When they are laid separately from power system
cables, distances of up to 500 m are possible.
An arbitrary mixture of voltage sensor, current sensor, two-wire and
four-wire transducers can be connected. For two-wire transducers, there are
four short-circuit protected supply terminals at the front connector.
!Caution
To use two-wire transducers, the reference potential (common input) of these
channels must be connected to L-. This defeats the isolation between the
channels and the supply voltage L+/L-.
Note that the bus interface of the module is activated with 24 V via enable
lines F+ and F- at the front connector.

9.5 The 465 Analog Input Module
9.5.1 Design
The modules are designed as plug-in PCBs for central controllers and
expansion units with a backplane connector and with a blade connector to
accept a plug-in front connector. You can directly connect the process signal
lines to the front connector, which is available separately, with screw or
crimp terminals.
Situated on each module is an addressing switch with six rockers to set the
module address. Analog input modules also have two switches on the side
with eight rockers for setting the mode, and receptacles for range cards.
The modules are protected by covers on both sides.

9.5.2 Function of the Enable Input
The 465 module has an enable circuit. You can use the enable inputs to
switch off individual modules whilst the PLC is in operation. This means
that:
The module can no longer be addressed by the user program.
Modules which are switched off can be removed or inserted during operation.
If this is not necessary, operate the module with the enable input switched
off.

The enable circuit requires an external 24 V voltage at enable inputs F+/F- in
the front connector. If there is no voltage at F+/F-, the modules will not
acknowledge.
When the front connector is swivelled away from the front strip of the
module, the supply of power to the enable input is interrupted, i.e. the
module is switched off and can no longer be addressed by the user program: a
timeout (QVZ) occurs in the CC.
The 465 module additionally offers the facility for changing the enable
mode. The module has a jumper accessible from above in the vicinity of the
addressing switch.
Enable Jumper
Figure 9-19 Enable Input and Enable Jumper
Jumper inserted: Enable input (F+/F-) active (factory setting)
Jumper open: Enable input (F+/F-) switched off
Examples of functioning of the enable inputs:
To switch off individual subprocesses, i.e. outputs of various modules can
be operated from a common load supply and yet activated separately.
The load voltage of individual modules can be monitored without
additional circuitry. Any reactions to failure of the load voltage can be
programmed in the QVZ (timeout) organization block.

You must observe the following when configuring systems:
Switching on At the latest 100 ms after power-up of the PLC, the voltage
must be present at the enable inputs of the I/O modules.
Switching off When the PLC has been switched off, the voltage at the
enable inputs of the I/O modules must still be present as
long as the internal 5 V voltage is present.
You should observe the following instructions for switching off CCs and
equipment for supplying power to the enable inputs.
When there is a need to switch off the load power supply separately without
affecting the enabling of modules, there are the following possibilities for
producing the enable voltage. These exist even when the load power supply
is used without an additional capacitor and common shutdown.

9.5.3 Special Features of the 465 Analog Input Module
The 465 analog input module executes integrating processing of the digital
input signals; periodic system interference is thus suppressed.
You can adapt the process signals, according to the application, to the input
level of the analog-to-digital converter of the module with plug-in range
cards (resistor dividers or shunt resistors).
To monitor the sensors connected to the inputs, you can use the
6ES5 498-1AA11 range card (through-connection card) to implement the
“broken wire detection” mode. You can activate broken wire detection for
8 or 16 inputs in 16-channel operation, and for 4 or 8 inputs in
8-channel operation.
Each time the input value is about to be encoded, a constant current is briefly
(1.6 ms) switched to the input terminals and the resultant current is checked
for a limit value. If a digital voltmeter is used to measure the signal at the
input, these current pulses may appear to indicate fluctuation of the signal.
The encoded value, however, is not affected.
If these apparent fluctuations of the signal are disturbing, for example, during
startup, you can switch the tripping current to the inactive state on the 465
analog input modules: apply + 24 V to pin 24 of the front connector, and 0 V
to L-. You must additionally set the mode switch to “without broken wire
detection.”
In the event of open-circuit of the sensor or its line, the voltage exceeds the
limit and a broken wire is indicated (bit 1 in data byte 1). The
analog-to-digital converter encodes the value 0.
A broken wire signal is only useful when the 6ES5 498-1AA11
through-connection card is used. With all other measurement cards, a broken
wire signal will result in incorrect reactions. Further details relating to the
broken wire signal can be found in Section 9.5.10.
If the measuring range is exceeded, the overflow bit (bit 20 of the low byte)
is set.
You have a choice of the cyclic sampling and selective sampling modes.
In the cyclic sampling mode, the module continuously encodes all measured
values. The digitized measured values are stored under the channel-related
address on the module (the high byte under this address, and the low byte
under the next higher address). The measured values can then be read by the
module at any time without waiting. When you operate the module in this
mode, you can set a module address from 0 to 255.

System Manual
C79000-G8576-C199-07
In the selective sampling mode, a measured value is encoded on the central
initiative of the CPU. At the start of conversion, the module must be
addressed once with a write operation (T PW) by the user program. An active
bit (T = 1) is set during encoding.
With the transition to T = 0, the measured value becomes valid. With
non-constant cycle times, there may be non-periodic measured value
aquisition. If you operate the module in this mode, you must set a module
address from 128 to 255. You can also use the address range from 0 to 127
for selective sampling after appropriate programming in DB 1 of the user
program.
Another method is that of time-controlled program processing. With this
method, certain program segments (e.g. FB 13) are automatically inserted
into program processing at the 100 ms rate by a time-controlled block
(OB 13). A constant timebase is thus achieved.

9.5.4 Setting the Module Address
You set the module address on the addressing switch. This also establishes
the necessary assignments between user program and process connection.
The module address is the sum of the decimal significances of the switch
rockers in the On setting ().
One data word = two data bytes is required to process an input. A module
with 8 inputs therefore reserves 16 byte addresses, and a module with
16 inputs or outputs reserves 32 byte addresses.
You can affix the adhesive label with the desired module address on a free
labeling field under the addressing switch.
The switch rockers to be set for the module address specified as a decimal
number (address bit ADB) are marked by dots on the label.
Note
Press the individual rockers of the addressing switch downwards with a
ballpoint pen or similar object, but not a pencil. Ensure that all the switches
are operated properly (meaning pressed past the latching point).

Note
The start address of the analog module must be a multiple of the double
channel number.
8 channels : 0, 16, 32, 48, ... 240
16 channels : 0, 32, 64, 96, ... 224
If one of the inputs or outputs (channel 0 to 7 or 0 to 15) of a module is to be
addressed, the relevant subaddress must be specified in the program.
The subaddress of the input or output, based on the start address of the
module, is given by:
Start address + 2 x channel no. = subaddress
Example:
Analog input module with 8 or 16 inputs
The address is the sum of the significances set with the individual coding

A module with 8 or 16 inputs (channel 0 to 7 or 0 to 15) and start address 160
reserves the address range from

160 to address 160 + 15 x 2 = 190
In this example, the next free address for another module is 176 or 192.
With the 465 analog input module, the size of the address range depends on
the number of channels set (8 or 16).
Addresses already assigned must not be set again.

However, analog input modules and analog output modules may be given the
same address with cyclic sampling because they are distinguished by the user
program. This is not possible with selective sampling.
For cyclic sampling, you can address the module in the address range from
0 to 255, and for selective sampling from 128 to 255. For selective sampling,
you can also use the address range from 0 to 127 after appropriate
programming in DB 1 of the user program.
Example:
On an analog input module with start address 160 (IB 160 = input byte 160),
input channel 3 is to be scanned by the program.
Step Action
1Affix the self-adhesive label with address 160 on the free field under the
addressing switch on the module. ADB 5 and ADB 7 are marked on the
label.
2Press the appropriate rockers of the addressing switch down on the side
marked by a dot on the module cover. Set the other rockers to the opposite
setting. This way the start address of the module is set.
ADB 5 and ADB 7 results in 25 + 27 = 32 + 128 = 160
3Enter the address 160 + 3 x 2 = 166 in the program for input channel 3.

9.5.5 Removing and Inserting Modules
!Warning
When removing and inserting the front connector during operation,
hazardous voltages of more than 25 V AC or 60 V DC may be present at the
module pins. When this is the case at the front connector, live modules may
only be replaced by electrical specialists or trained personnel in such a way
that the module pins are not touched.
During operation, the front connector and module must not be removed or
inserted without the enable jumper or active enable circuit.
Install an analog input/output module as follows:
Step Action
1Release the upper locking bar on the subrack and swivel it upwards and
out.
2Insert the module at the desired slot in the subrack and push it back in the
guides.
3Latch the module by rotating the locking pin by 90o at the lower end of
the module. It must no longer be possible to pull the module forwards.
4Engage the front connector on the support pin of the module. The width
of the support pin also provides keying to prevent front connectors from
being fitted to the wrong modules (for example, front connectors with
115/230 V AC wiring cannot be plugged into analog modules).
5Tighten the screw in the upper part of the front connector.

Remove an analog input/output module as follows:
Step Action
1Release the upper locking bar on the subrack and swivel it upwards and
out.
2Slacken the screw in the upper part of the front connector. This causes the
front connector to be pressed out of the female connector of the module.
Contacts F+ and F- of the enable input at the upper end of the front
connector are thus opened first. If the enable input is active, power is re-
moved from the outputs and the module is isolated from the S5 bus.
3Swing the front connector out and lift it away from the support pin of the
module.
4Release the module by rotating the locking pin by 90o at the lower end of
the module. You can pull the module out of the subrack with a grip with
swivels outwards.

9.5.7 Connecting the Signal Lines
For connection of the signal lines, front connectors for 20 and
40 mm mounting width with crimp connection and 40 mm mounting width
with screw connection are available (screwdriver blade width: 3.5 mm,
maximum torque: 0.8 Nm).
Use stranded conductor to facilitate handling of the front connector. Ferrules
are not required for screw connections, because the screw terminals are
provided with wire protection.
When the crimp contact is inserted in the plastic body of the front connector,
a click can clearly be heard. This indicates that the contact is engaged. For
jumpering or to correct the wiring, you can remove the contacts with a
releasing tool (see Ordering Information) without having to pull out the front
connector.
Ferrules are not required for screw connections, because the screw terminals
are provided with wire protection. You can use ferrules of 7 mm in length to
DIN 46228. The maximum terminal area is 2 x 2.5 mm2.

9.5.8 Connecting a Compensating Box for Thermal
E.M.F. Measurement
If the room temperature fluctuations at the reference point (for example, in
the terminal box) affect the measurement result and you do not wish to use a
thermostat, you can compensate for the effect of temperature on the reference
point with a compensating box. Between - 10 and + 70 oC, it compensates for
the change in thermal e.m.f. caused by temperature deviation (compensating
box, see Catalog MP 19). Ensure that the compensating box has thermal
contact with the terminals.
If the compensating box is aligned at 20 oC, this must be taken into account
in temperature evaluation (20 oC measuring point temperature = 0 mV).
Pins 22 and 23 are extended on analog input modules as an input for the
compensating voltage. You must select a common input loop for all inputs on
mode switch 2.
The compensating box must be connected in a floating circuit. The power
supply unit of the compensating box must have a grounded shield winding to
avoid AC system interference being picked up. A separate compensating box
with its special power supply unit is required for each analog input module.

9.5.9 Connecting Resistance Thermometers to the 465 Analog Input
Module
The relevant resistance thermometer is fed with a current of 2.5 mA (IC+/IC-)
by a constant current generator via a 6ES5 498-1AA11 card. The voltage at
the Pt 100 is picked off at measurement inputs M+ and M-.
If only inputs 0 to 3 are assigned to resistance thermometers, you can connect
other current and voltage sensors to inputs 4 to 7 by means of a coding key. If
you use the Pt 100 for measurement, you cannot utilize channels 12 to 15.
Channels 8 to 11 supply the resistance thermometers which are connected at
inputs 0 to 3.
Note that the mode of the module is set to the 500 mV voltage range.

1) When cards 6ES5 498-1AA21, 6ES5 498-1AA31 or 6ES5 498-1AA61 are used, no broken wire signal may be activated for this
group of channels (CH4 to CH7).
2) If cards 6ES5 498-1AA41 or 6ES5 498-1AA71 are used, a short-circuit jumper is not required.

If the mode “without broken wire signal” is selected on the module, an
open-circuit of the resistance thermometer is indicated with an overflow.
Unassigned channels can be used for voltage or current measurement if the
current flow outputs relating to the particular measuring channel are shorted
with a wire jumper. Without this jumper, the error bit would be set for this
channel and the value 0 would be encoded.
When set to “resistance thermometer,” switch 7 of mode switch I of the
465 analog input module allows broken wire monitoring of the IC+ lines to
the resistance thermometer (Pt 100 constant current supply). In the event of
open-circuit of this line, the error bit is set as for the other lines.
At the “voltage/current” (mV/mA) setting, the IC+ lines are not monitored for
broken wire. (The error bit is not set for an open-circuit of this line.) You
should choose this switch setting if you exclusively measure voltages or
currents.

When Pt 100 resistance thermometers are connected, the maximum
temperature in the rated range is 266 oC. If it can be ensured that the
temperature does not exceed 850 oC, the input value may extend into the
overrange. The resolution is then 4095 units. Unused inputs can be utilized
for voltage measurements in the 500 mV range (see front connector
assignments).

Measuring range 500 mV; card with 31.25 ohm shunt
(6ES5 498-1AA51/AA71)
The 4 to 20 mA range is resolved to 2048 units at an interval of 512 to 2560.
If you require a representation from 0 to 2048, you must subtract 512 units by
software. Please note the following:
a broken wire signal cannot be emitted.
detection of the overrange can be achieved by scanning bits 29 and 211.
a broken wire can be detected with currents < 3 mA.
If you short-circuit the positive and negative terminals of the transducer
when using the 6ES5 498-1AA51 range card (for a two-wire transducer),
the current is limited to about 28 mA. Until the thermal current limiting
circuit responds in the range card (about 3 s), a short-circuit current of
approximately 250 mA flows.

9.6 The 466 Analog Input Module
9.6.1 Design The module is designed as a plug-in PCB for central controllers and
expansion units with a backplane connector and with a blade connector to
accept a plug-in front connector. You can directly connect the process signal
lines to the front connector, which is available separately, with screw or
crimp terminals.
9.6.2 Special Features of the 466 Analog Input Module
The 466 analog input module processes the digital input signals by encoding
the instantaneous value; periodic system interference is therefore not
suppressed.
You select the measuring ranges with a switch setting for every four
channels.
9.6.3 Startup for Analog Input 466-3LA11
The mode of the 466 analog input module must be set exclusively via
switches on the board. Figure 9-26 shows the designations and locations of
switches on the board.

9.6.5 Removing and Inserting Modules
!Warning
When removing and inserting the front connector during operation,
hazardous voltages of more than 25 V AC or 60 V DC may be present at the
module pins. When this is the case at the front connector, live modules may
only be replaced by electrical specialists or trained personnel in such a way
that the module pins are not touched.
During operation, the front connector and module must not be removed or
inserted without the enable jumper or active enable circuit.
Install an analog input/output module as follows:
Step Action
1Release the upper locking bar on the subrack and swivel it upwards and
out.
2Insert the module at the desired slot in the subrack and push it back in the
guides.
3Latch the module by rotating the locking pin by 90o at the lower end of
the module. It must no longer be possible to pull the module forwards.
4Engage the front connector on the support pin of the module. The width
of the support pin also provides keying to prevent front connectors from
being fitted to the wrong modules (e.g. front connectors with
115/230 V AC wiring cannot be plugged into analog modules).
5Tighten the screw in the upper part of the front connector.

Remove an analog input/output module as follows:
Step Action
1Release the upper locking bar on the subrack and swivel it upwards and
out.
2Slacken the screw in the upper part of the front connector. This causes the
front connector to be pressed out of the female connector of the module.
Contacts F+ and F- of the enable input at the upper end of the front
connector are thus opened first. If the enable input is active, power is
removed from the outputs and the module is isolated from the S5 bus.
3Swing the front connector out and lift it away from the support pin of the
module.
4Release the module by rotating the locking pin by 90o at the lower end of
the module. You can pull the module out of the subrack with a grip with
swivels outwards.

9.6.7 Connecting the Signal Lines
For connection of the signal lines, front connectors for 20 and 40 mm
mounting width with crimp connection and 40 mm mounting width with
screw connection are available (screwdriver blade width: 3.5 mm,
maximum torque: 0.8 Nm).
Use stranded conductor to facilitate handling of the front connector. Ferrules
are not required for screw connections, because the screw terminals are
provided with wire protection.
When the crimp contact is inserted in the plastic body of the front connector,
a click can clearly be heard. This indicates that the contact is engaged.
For jumpering or to correct the wiring, you can remove the contacts with a
releasing tool (see ordering information) without having to pull out the front
connector.
Ferrules are not required for screw connections, because the screw terminals
are provided with wire protection. You can use ferrules of 7 mm in length
to DIN 46228. The maximum terminal area is 2 x 2.5 mm2.
!Caution
Only extra-low voltage 60 V DC with safety separation from system voltage
may be used for the 24 V DC supply and for the 24 V DC input signals.
Safety separation can be implemented to the requirements of, amongst other
sources, VDE 0100 Part 410/HD 384-4-41/IEC 60364-4-41 (as functional
extra-low voltage with safety separation) or
VDE 0805/EN 60950/IEC 60950 (as safety extra-low voltage SELV) or
VDE 0106 Part 101.

9.6.8 Connecting Sensors to the 466 Analog Input Module
The connections for the 466 analog input module depend on the type of
measurement (with respect to ground or differential measurement).
For measurement with respect to ground, all signal lines have a common
reference point. This is achieved by connecting all the M inputs in use to one
point. Since this type of measurement is susceptible to interference, the
signal sources should be arranged in the vicinity of the 466 analog input
module.
16 channels are available; unused channels must be shorted
(jumper between M+ and M-).
The channels have the following designations on the module:
Channel 0: M0 +
M0 -
Channel 1: M1 +
M1 -
: :
Channel 15 M15 +
M15 -
Channels are arranged in groups of four, for which you can set separate
measuring ranges:
Channel group I: Channels 0 to 3
Channel group II: Channels 4 to 7
Channel group III: Channels 8 to 11
Channel group IV: Channels 12 to 15

The differential measurement is a method of compensating for interference
on the line. Each signal source is assigned its own signal reference line. The
differential measurement between signal line and signal reference line thus
compensates for the interference acting on both lines.
You must also short-circuit the unused channels with this measuring method
(jumper between M+ and M-).
Differential measurement is required:
if the sensors are at different potentials;
if various signal sources are not close to each other;
if there is a need to measure signals with high precision;
and when a high level of interference is expected.

Figure 9-34 Digital Result Representation
Bits 0 to 2 in byte 1 have no influence on the measured value, they only give
information on measured-value representation. The following table describes
their significance in more detail.
Bit Significance Signal Status Meaning of the
Signal Status
OV Overflow bit 1 Range exceeded *
E Error bit 1 Broken wire
A Active bit 0 Not used
*A measuring-point overflow does not affect the overflow bits of the other channels;
i.e. the measured values of unaffected channels are correct and can be evaluated.
Please note the following special features:
Bit 7 in the high byte (212) indicates the sign for bipolar measured-value
representation (two’s complement and value with sign).
Bit 6 in the high byte (211) is not used in the case of bipolar
measured-value representation (no overrange).
The 466 module has no overrange.
Selective sampling is not possible with the 466 module
(active bit is not set).

9.7 The 470 Analog Output Module
9.7.1 Design
The module is designed as a plug-in PCB for central controllers and
expansion units with a backplane connector and with a blade connector to
accept a plug-in front connector. You can directly connect the process signal
lines to the front connector, which is available separately, with screw or
crimp terminals.
Situated on each module is an addressing switch with six rockers to set the
module address.
The modules are protected by covers on both sides.
Blade Connector
Addressing Switch
Front Connector
Figure 9-37 Analog Output Module
9.7.2 Function of the Enable Input
The 470 module has an enable circuit. You can use the enable inputs to
switch off individual modules whilst the PLC is in operation.
This means that:
The module can no longer be addressed by the user program.
On analog output modules, the last analog value to be output is retained.
Modules which are switched off can be removed or inserted during operation.
If this is not necessary, operate the module with the enable input switched
off.

The enable circuit requires an external 24 V voltage at enable inputs F+/F- in
the front connector. If there is no voltage at F+/F-, the modules will not
acknowledge.
When the front connector is swivelled away from the front strip of the
module, the supply of power to the enable input is interrupted, i.e. the
module is switched off and can no longer be addressed by the user program: a
timeout (QVZ) occurs in the CC.
The -4Ux12/13-type modules additionally offer the facility for changing the
enable mode. The modules have a jumper accessible from above in the
vicinity of the addressing switch.
Enable Jumper
Figure 9-38 Enable Input and Enable Jumper
Jumper inserted: Enable input (F+/F-) active (factory setting)
Jumper open: Enable input (F+/F-) switched off
Examples of functioning of the enable inputs:
To switch off individual subprocesses, i.e. outputs of various modules can
be operated from a common load supply and yet activated separately.
The load voltage of individual modules can be monitored without
additional circuitry. Any reactions to failure of the load voltage can be
programmed in the QVZ (timeout) organization block.

You must observe the following when configuring systems:
Switching on At the latest 100 ms after power-up of the PLC, the voltage
must be present at the enable inputs of the I/O modules.
Switching off When the PLC has been switched off, the voltage at the
enable inputs of the I/O modules must still be present as
long as the internal 5 V voltage is present.
However, you must ensure that the 24 V load supply for
analog output modules is switched off together with the
PLC. If the supply voltage is still present at the modules
and the PLC is switched off, the output values can drift.
(The analog holding elements for the outputs will no lon-
ger be refreshed with the current value, because there is no
5 V supply to the modules from the bus.)
You should observe the following instructions for switching off CCs and
equipment for supplying power to the enable inputs.
When there is a need to switch off the load power supply separately without
affecting the enabling of modules, there are the following possibilities for
producing the enable voltage. These exist even when the load power supply
is used without an additional capacitor and common shutdown.

9.7.3 Special Features of the 470 Analog Output Module
The BASP signal is not interpreted by the 470 analog output module. Once
output, a value is retained.
You can output analog values to the process via analog output modules with a
function block from the “basic functions” package.
9.7.4 Setting the Module Address
You set the module address on the addressing switch. This also establishes
the necessary assignments between user program and process connection.
The module address is the sum of the decimal significances of the switch
rockers in the On setting ().
One data word = two data bytes is required to process an input or an output.
A module with 8 inputs or outputs reserves 16 byte addresses.
You can affix the adhesive label with the desired module address on a free
labeling field under the addressing switch.
The switch rockers to be set for the module address specified as a decimal
number (address bit ADB) are marked by dots on the label.
Press the individual rockers of the addressing switch downwards with a
ballpoint pen or similar object, but not a pencil.

For analog output modules ( 8 outputs) only the lowest address (start address)
is set. Other addresses (subaddresses) are decoded on the module.
Note
The start address of an analog module must be a multiple of the double
channel number.
8 channels : 0, 16, 32, 48, ... 240
Ensure that all the switches are operated properly (meaning pressed past the
latching point).
Do not use a pencil to set the addressing switch.
If one of the outputs (Channel 0 to 7) of a module is to be addressed, the
relevant subaddress must be specified in the program.
The subaddress of the output, based on the start address of the module, is
given by:
Start address + 2 x channel no. = subaddress
Example:
Analog output module with 8 outputs
The address is the sum of the significances set with the individual coding
switches.

However, analog input modules and analog output modules may be given the
same address with cyclic sampling because they are distinguished by the user
program. This is not possible with selective sampling.
For cyclic sampling, you can address the module in the address range from 0
to 255, and for selective sampling from 128 to 255. For selective sampling,
you can also use the address range from 0 to 127 after appropriate
programming in DB 1 of the user program.
Example:
On an analog output module with 8 outputs with start address 144
(IB 144 = output byte 144), output channel 7 is to be scanned by the
program.
Step Action
1Affix the self-adhesive label with address 160 on the free field under the
addressing switch on the module. ADB 4 and ADB 7 are marked on the
label.
2Press the appropriate rockers of the addressing switch down on the side
marked by a dot on the module cover. Set the other rockers to the opposite
setting. This sets the start address of the module.
ADB 4 and ADB 7 results in 24 + 27 = 16 + 128 = 144
3Enter the address 144 + 7 x 2 = 158 in the program for input channel 7.

9.7.5 Removing and Inserting Modules
!Warning
When removing and inserting the front connector during operation,
hazardous voltages of more than 25 V AC or 60 V DC may be present at the
module pins. When this is the case at the front connector, live modules may
only be replaced by electrical specialists or trained personnel in such a way
that the module pins are not touched.
During operation, the front connector and module must not be removed or
inserted without the enable jumper or active enable circuit.
Install an analog output module as follows:
Step Action
1Release the upper locking bar on the subrack and swivel it upwards and
out.
2Insert the module at the desired slot in the subrack and push it back in the
guides.
3Latch the module by rotating the locking pin by 90o at the lower end of
the module. It must no longer be possible to pull the module forwards.
4Engage the front connector on the support pin of the module.
The width of the support pin also provides keying to prevent front
connectors from being fitted to the wrong modules (for example,
front connectors with 1 15/230 V AC wiring cannot be plugged into
analog modules).
5Tighten the screw in the upper part of the front connector.

Remove an analog output module as follows:
Step Action
1Release the upper locking bar on the subrack and swivel it upwards and
out.
2Slacken the screw in the upper part of the front connector. This causes the
front connector to be pressed out of the female connector of the module.
Contacts F+ and F- of the enable input at the upper end of the front
connector are thus opened first. If the enable input is active, power is
removed from the outputs and the module is isolated from the S5 bus.
3Swing the front connector out and lift it away from the support pin of the
module.
4Release the module by rotating the locking pin by 90o at the lower end of
the module. You can pull the module out of the subrack with a grip with
swivels outwards.

9.7.7 Connecting the Signal Lines
For connection of the signal lines, front connectors for 20 and 40 mm
mounting width with crimp connection and 40 mm mounting width with
screw connection are available (screwdriver blade width: 3.5 mm,
maximum torque: 0.8 Nm).
Use stranded conductor to facilitate handling of the front connector.
Ferrules are not required for screw connections, because the screw terminals
are provided with wire protection.
When the crimp contact is inserted in the plastic body of the front connector,
a click can clearly be heard. This indicates that the contact is engaged.
For jumpering or to correct the wiring, you can remove the contacts with a
releasing tool (see ordering information) without having to pull out
the front connector.
Ferrules are not required for screw connections, because the screw terminals
are provided with wire protection. You can use ferrules of 7 mm in length to
DIN 46228. The maximum terminal area is 2 x 2.5 mm2.

9.7.8 Connecting Loads to the 470 Analog Output Module
The voltage at the load is measured at a high resistance via the sensor lines
(S+/S-) of voltage output QV, so that voltage drops on the load lines do not
falsify the load voltages. Lines S+(x) and S-(x) should therefore be directly
connected to the load (four-wire circuit). The voltage drops on the lines from
QV(x) to the load and from the load to MANA must not exceed 3 V.

If, with voltage outputs, an excessively great voltage drop must be expected
on the lines to the load, you must route the sensor lines S+(x) and S-(x) to the
load.
When voltage outputs are not used, the S+(x) sensor lines in the front
connector must be connected to the corresponding voltage output terminals
(QV(x)) with wire jumpers. The S-(x) sensor lines must be connected to
MANA with wire jumpers.
You must also insert the same jumpers if only current outputs are used.
Unused current outputs may remain open.
The maximum load for the current outputs including line resistance, must not
exceed 300 ohms.

The S+(x) and S-(x) sensor lines must be routed to the load (four-wire
circuit) if the voltage drop on the lines to the load is not negligible. The
common connection for the voltage outputs is MANA. If the voltage drop on
lines to the load is negligible, you can connect S+(x) to QV(x) and S-(x) to
MANA in the front connector.
When voltage outputs are unused, you must insert jumpers in the front
connector, e.g. QV(3) to S+(3) and S-(3) to MANA for unused voltage output
3 (see previous section).

10.1 Application
The monitoring module can be used in the expansion units of the
programmable controllers S5-115U, S5-135U and S5-155U.
The module monitors the data bus, the address bus and the control signals
MEMW/, MEMR/ and RDY/. Faults are displayed via four red LEDs on the
front panel. A group signal is output at the same time via a floating contact.
Following a fault, the module can be reset by means of the RESET key on
the front panel or the RESET input (see Section 10.2.3).
10.1.1 Design
The monitoring module is designed as a plug-in PCB in double Euroformat
with a 32-pin backplane connector for the S5 bus.
A connector for the relay contact and RESET input as well as one green
LED, four red LEDs and a RESET key are located on the front panel.

10.1.4 Fault Detection
From an address which has been set at switch S1, the data (55H or AAH) is
read by the CPU from the monitoring module. This data is to be written back
by the CPU to the address set at switch S2. The module inverts the accurate
incoming data bit by bit (from 55H to AAH or vice versa) which is read
again in the next cycle from the address set at S1.
If the data which has been set on the monitoring module is not returned
within the set monitoring time, the module signals a data bus fault.
Detectable faults
Interruptions of the data lines, short circuits to ground and + 5V, short
circuits between adjacent data lines, e.g. DB0-DB1, DB1-DB2 etc.
Non-detectable faults
Short circuits between even data lines DB0-DB2-DB4-DB6 and between odd
data lines DB1-DB3-DB5-DB7.
The addresses which have been set at switches S3 and S4 are only
“listened to” by the monitoring module, i.e. they do not output an
acknowledgement signal (RDY/) and are not active on the data bus. If one or
both addresses are not accessed again within the monitoring time, the
monitoring module signals an address bus fault.
Detectable / non-detectable faults
The same as for the data bus, if the inverse addresses 85 (55H) and
170 (AAH) have been set at the addressing switches S3 and S4 of all
monitoring modules.

System Manual
C79000-G8576-C199-07
A control line fault (R/W) occurs if
– the write signal (MEMW/) and the read signal (MEMR/) are active
simultaneously,
– the acknowledgement signal (RDY/) is active without a (MEMW/) or
(MEMR/) signal and
– the address line ’peripheral memory’ (PESP’) has not changed from
status “1” to “0.”
Evaluation of the control signal (PESP’) can be turned off with the
S5/7 switch. If the module is used in a programmable controller into which
only I/O modules may be inserted (i.e. no memory modules or CPs), this
switch must always be turned off. In this configuration, only I/O accesses to
the bus are performed and the PESP‘ signal always has the status “1.”
It should also be turned off when using the IM 301, IM 302 1), IM 304 and
IM 308 interface modules for expansion units since a permanent PESP‘
signal can be applied to them.
If a command output inhibit (BASP) is active, the “BASP” LED is lit.
If one or more faults occur, the corresponding LEDs are lit, the relay contact
commutes and the module no longer acknowledges with the RDY/ signal.
This timeout can be suppressed by opening the S5/8 switch.
10.1.5 Resetting
There are several ways of resetting the module:
– CPKL/ signal = “1” (when the PLC is switched on);
– Trailing edge of the BASP signal (during startup of the PLC or
following return of the load voltage);
– Applying 24 V to the front connector X4 between connections 4
(RESET input) and 6 (L-);
– Linking connections 4 (RESET input) and 5 (L+) with connector X4.
1) In the S5-115U, the monitoring module cannot be used together with the IM 302 / 311 link.

10.3 Operation
The addresses set at these switches are acknowledged by the monitoring
module with RDY/ and are therefore not to be used again for inputs and
outputs in this programmable controller (double addressing is not allowed).
No acknowledgement signal (RDY/) is returned by the monitoring module to
the addresses set the switches S3 and S4. These addresses must be accessed
by the programmable controller as input or output addresses. This means that
they must be occupied by I/O modules or by one monitoring module at
switches S1 and S2. These modules must have been inserted into the last
expansion unit.
To achieve optimum address bus monitoring, inverse addresses should be
used [e.g. 85 (55H) 2) and 170 (AAH)]. It is advisable to make sure that the
setting of switches S3 and S4 is the same on all monitoring modules used.
The setting of switches S1and S2 as well S3 and S4 should be the same on
the monitoring module in the last expansion unit.

3) Possible addresses 0 (00H) to 255 (FFH)
4) To achieve optimum fault detection, set the inverse addresses 85 (55H) and 170 (AAH) at S1 and S2.
5) Since the addresses of the monitoring module switches S3 and S4 are not acknowledged, this must be done by the
monitoring module contained in the last expansion unit (the most remote from the central controller). The addresses
85 (55H) or 170 (AAH) of this monitoring module must be coded at switches S1 or S2, respectively.
These addresses may no longer be occupied for I/O tasks.

7) To achieve maximum fault detection, select inverse addresses > 127, e.g. 213 (D5H) and 170 (AAH). In this combination,
the address bit ADB 7 is not monitored.
8) If ADB 7 is also to be monitored, the address 84/85 (54H/55H) in the last expansion unit must be occupied by an input or
output module and cyclically accessed by the user program. Set address 85 (55H) in place of 213 (D5H) at switch S3 of all
monitoring modules. Select any address between 128 (80H) and 255 (FFH) for switch S1 of the monitoring module in the
last expansion unit. As an alternative, you may access the address at S1 of the monitoring module in the last expansion unit via
direct access (without process image) using L PB 85 or L PY 85. Then, the addresses 84 and 85 (54H) and (55H) in the process
image may no longer be used by other inputs. The address at S3 of all monitoring modules is then also to be set to 85 (55H).

Select the monitoring time (between 125 ms and 1 s) by switching one of the
switches S5/1 to S5/4 to ON. If none of the four switches S5/1 to S5/4 is in
the ON position, for safety reasons the monitoring time has been set to 1 s.
If serial interface modules and the link between IM 304 and IM 314 are used,
the PESP‘ monitoring is to be switched off (see Section 10.1.4: Control line
faults).
Should the acknowledgement signal (RDY/) not be suppressed in the event of
a fault, the switch S5/8 must be in the OFF position.
When a BASP signal is active, the RDY/ signal will always be output.

B.1 What is ESD?
All electronic modules are equipped with large-scale integrated ICs or
components. Due to their design, these electronic elements are very sensitive
to overvoltages and thus to any electrostatic discharge.
These Electrostatically-Sensitive Devices are commonly referred to by the
abbreviation ESD.
Electrostatically-sensitive devices are labeled with the following symbol:
!Caution
Electrostatically-sensitive devices are subject to voltages that are far below the voltage
values that can still be perceived by human beings. These voltages are present if you
touch a component or the electrical connections of a module without previously being
electrostatically discharged. In most cases, the damage caused by an overvoltage is not
immediately noticeable and results in total damage only after a prolonged period of
operation.

B.2 Electrostatic Charging of Persons
Every person with a non-conductive connection to the electrical potential of
its surroundings can be charged electrostatically.
Figure B-1 shows you the maximum values for electrostatic voltages which
can build up on a person coming into contact with the materials indicated in
the figure. These values are in conformity with the specifications of
IEC 801-2.

B.3 General Protective Measures Against Electrostatic Discharge
Damage
Make sure that the personnel, working surfaces, and packaging are
sufficiently grounded when handling electrostatically-sensitive devices.
You thus avoid electrostatic charging.
You should touch electrostatically-sensitive devices only if it is unavoidable
(for example, during maintenance work). Hold modules without touching the
pins of components or printed conductors. In this way, the discharged energy
cannot affect the sensitive devices.
If you have to carry out measurements on a module, you must discharge your
body before you start the measurement by touching grounded metallic parts.
Use grounded measuring devices only.
