Input data is transmitted to the parallel S5 bus by the input modules, read there by the 318-3 interface module and transferred to the serial interface after buffering. Exchange of input and output data via the serial interface as well as data exchange via the parallel S5 bus on the backplane of the mounting rack both take place within one cycle. These cycles are time-independent thanks to buffering and run asynchronously. In addition, the diagnostic bits F0, F2 and BASP are generated by the 318-3 interface module according to its operating status and transmitted to the 308-3 interface module ( 3.5). You can set the baud rate and the input/output area or page area using the coding switch (switch S2) on the module board ( 3.3).

An adapter casing (Order No. 6ES5 491-0L .11) is required for use in expansion units for block-type modules. There are two backplane connectors (X1, X2) on the module which make contact with the parallel S5 bus on the backplane of the mounting rack. As well as the RESET switch for resetting the module or initiating a new configuration run, there is also a four-way plug connector on the frontplate into which the interface connector supplied is plugged. Also on the frontplate are a red FAULT LED and a green ON LED which show the operating status of the module. Coding switch S2 on the PCB can be used to set the baud rate and the input/output area or the page area ( 3.3). 1-2 EWA 4NEB 812 6054-02a aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaa 318-3 Interface Module X1 X2 X3 X4/X5/X6/X7 48-way backplane connector 32-way backplane connector 4-way plug connector for serial interface Connector for test purposes only EWA 4NEB 812 6054-02a System Overview Note: The X4, X5, X6 and X7 jumpers are plugged in on delivery of the modules and must not be changed. 1 RESET switch 2 Green ON LED (operating status display) 3 Red FAULT LED 4 Plug receptacle for the serial interface BR1 Jumper 1 (open) S2 "Baud rate " switch and "Input/output area or page area" switch Figure 1-2 Design of the 318-3 Interface Module 1-3 aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa 2 Hardware Installation 2.1 Possible Slots for the 318-3 Interface Module . . . . . . 2 - 2 2.2 2.2.1 2.2.2 Assembly . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .2.

Slide the module slowly in until you feel resistance. Press the module into place at the top and bottom. To remove, use the handle to pull the module out with a gentle up and down motion. 2.2.2 Assembly in Expansion Units for Block-Type Modules If you wish to use the module in an expansion unit for block-type modules, you require an adapter casing (Order No. 6ES5 491-0L .11). To install the interface module in an adapter casing, push the module along the guide rails into the casing. Lock the module into place with the excentric locking collars at the top and bottom of the casing. If an opening remains on the front after the module has been inserted, cover it with a blanking plate. EWA 4NEB 812 6054-02a 2-3 Hardware Installation 2.3 318-3 Interface Module Transmission Cable To ensure error-free data transfer between the 318-3 interface module and the 308-3 interface module, please note the following points with regard to connecting the transmission cable. Comprehensive information regarding selection and laying of transmission cables can be found in the 308-3 interface module manual. 2.3.1 Signal Line Connections The 318-3 interface module is supplied with the interface connector for connecting the transmission cable to the serial interface. The screw-type connections are suitable for stranded conductors with a crosssection of between 0.5 mm2 (20 AWG) and 1.5 mm2 (15 AWG). Core end sleeves are recommended. The serial interface is floating. A connection schematic is shown below ( Figure 2.2) Incoming transmission cable 1 2 3 4 not assigned not assigned S S-N* Outgoing transmission cable * S-N = Negated signal Figure 2-2 Connecting the Transmission Cables If you loop the transmission cable through from one node (318 interface module or ICM 560) to the other, clamp the incoming and outgoing transmission cables in parallel on the front connector. If you should mistakenly cross the wires of one or more interface modules, it will be impossible to reference these modules. The 308-3 interface module will not detect an interface error. 2-4 EWA 4NEB 812 6054-02a 318-3 Interface Module Hardware Installation 2.3.2 Terminating Resistor Each interface chain leading from the 308-3 interface module must be terminated at the last node with a standard 120 ohm, 0.25 W carbon layer resistor (supplied with the 308-3 interface module). If the 318-3 interface module in question is the last node of an interface chain, simply connect the resistor between terminals 3 and 4 of the front connector. Before you do this, however, be sure to slide the insulation sleeve over the resistor (also supplied with the 308-3 interface module) in order to prevent unintentional contact with the connecting wires ( Figure 2-3). Ensure that a good contact is made. If possible, press the resistance wires together with the flexible transmission cable into the same core end sleeves.

Continue the shielding right up to the interface connector without grounding it again. In the case of expansion units for block-type modules, clamp the transmission cable shielding to the standard sectional rail using a 6ES5 728-8MA11 grounding clamp and then run the cable on to the interface connector. The grounding measures apply both to incoming and outgoing transmission cables.

If this rule is not followed, the expansion unit will not reply to messages of the 308-3 interface module during the configuration run. As a result, the addresses of the I/O modules in the relevant expansion unit will not be entered in the process I/O image on the CPU and you will not be able to reference them. During a successful power-up procedure, the green ON LED and the red FAULT LED will light up as soon as you switch on the expansion unit power supply. After a successful configuration run by the 308-3 interface module, the fault LED on the 318-3 interface module will go off and data exchange will begin. A configuration run is automatically executed when power is restored after a power failure in the central controller or in the whole system. EWA 4NEB 812 6054-02a 3-1 Start-Up 318-3 Interface Module Changing the Modules in the Expansion Unit The expansion unit must be reconfigured via the 318-3 interface module each time the module complement is changed in the expansion unit. Configuration in the expansion unit is initiated by pressing the RESET switch on the 318-3 interface module. This resets all output modules. Following this, BASP will apply at least until the first valid message, i.e. the red FAULT LED will light up. After configuration of the 318-3 interface module , the 308-3 interface module must also execute a configuration run. For this purpose, set the mode selector of the 308-3 interface module to OFF and back again to ON. aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaa Switching Off the Expansion Unit Note: aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaa Make sure that the power supply of the expansion unit is switched off after or simultaneously with the power supply of the central controller. If this rule is not followed, the higher-level central controller will detect a timeout (QVZ) and a power failure (NAU) in the expansion unit. As a result, the double error (QVZ and NAU) will prevent the system from restarting after power is restored to the expansion unit. 3-2 EWA 4NEB 812 6054-02a 318-3 Interface Module 3.2 Start-Up Data Exchange Using a serial transmission procedure, I/O data is exchanged in half-duplex mode on the master-slave principle between the central controller or expansion unit and the expansion unit. The interface for connecting the transmission cable is floating and is similar to the RS 485 standard interface of the EIA (Electronic Industries Association). You can unplug the interface connector at one of the nodes during operation without interrupting the transmission line to the other nodes (party line). A terminating resistor (120 ohms, 0.25 W) is required on the end of each interface chain originating at the 308-3 interface module. As is usual with the input/output modules of the U range, the individual addresses of the modules are set in the expansion units.

Noise immunity can be improved for slower baud rates by using a filter. Baud rate Number of check bytes Filter 375,000 bps 187,500 bps 62,500 bps 31,250 bps 1 2 2 2 no no yes yes After a fault has been detected, the message is repeated twice before an error message occurs. Parasitic signals can cause a unit to switch off automatically. However, the system prevents erroneous setting of outputs. After a cold restart following a fault, the 308-3 interface module executes a reconfiguration run. EWA 4NEB 812 6054-02a 3-3 Start-Up 318-3 Interface Module Please note the following during configuration: - If you expect severe interference, you should use one of the two lowest baud rates. - If you have to select a high baud rate for reasons of speed, please pay careful attention to the guidelines for connecting and laying transmission cables. 3.3 Defaults on the Module Before putting the module into service, you must set the baud rate and the input/output or page area on the coding switch (Switch S2). Use a ballpoint pen or similar pointed object, but not a pencil, to set the switch blocks. In the following setting examples, a pressed switch is represented by: *. Switches S2.5 and S2.6 are not assigned. 3.3.1 Baud Rate You will achieve the greatest possible noise immunity on your data transmission line if you select the lowest possible baud rate. However, take the required response speed of the process into account . The response speed drops with the baud rate. Set the same baud rate for all nodes as that set for the 308-3 interface module. The baud rate of the transmission line is set using switches S2.1 and S2.2 ( Figure 3-1).

If you use page addressing, you must set the page area (Qn, Qn+1, Qn+2, Qn+3) on the 318-3 interface module within which you wish to communicate with the 308-3 interface module ( Figure 3-2). For this purpose, Qn Qn+1 Qn+2 Qn+3 corresponds to area corresponds to area corresponds to area corresponds to area P Q IM3 IM4 You will find further information on page addressing (multiplying the Q area) in the 308-3 interface module manual.

This transmission time depends on the module configuration in the expansion unit and the baud rate set. By defining the module addresses in the expansion unit without gaps, you can achieve minimal transmission times on the serial transmission link. Each address gap generates new messages with additional address header and control characters. This increases the transmission time tEU . Within the expansion unit, data is transferred to the I/O modules via the parallel S5 bus. The time required for this is negligible and already accounted for in tEU . You will find the relevant values of tEU in the following table: aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa Table 3-1 Transmission Time tEU Baud rate 375,000 187,500 62,500 31,250 bps bps bps bps Transmission Time tEU c x 3.0 ms/EU + d x 0.09 ms/byte c x 4.5 ms/EU + d x 0.12 ms/byte c x 8.5 ms/EU + b x 0.25 ms/byte c x 13.0 ms/EU + b x 0.40 ms/byte The parameters c and d are defined as follows: c = Total number of expansion units connected to the 308-3 interface module by the 318-3 interface module (both chains) d = The sum of all input and output bytes from all expansion units You will find comprehensive information on the transmission time of the serial transmission link in the 308-3 module manual. 3-6 EWA 4NEB 812 6054-02a 318-3 Interface Module 3.5 Start-Up Error Diagnostics Diagnostic byte No. 0 contains the diagnostic bits for expansion units. You can tell from this bit pattern whether an error has occurred and, if so, which error. The relevant bit then has signal state "1". Diagnostic Bits for Expansion Units Bit 7 6 5 4 3 2 1 0 BASP 0 0 0 0 F2 0 F0 F0: * One or more expansion units no longer accessible: e.g. 318-3 interface module supply voltage has failed, the interface connector has been unplugged, the 318-3 interface module has been disconnected, interrupt on the line. * Frequent interference on the transmission line: Messages are repeated twice; if no valid data is received (BCH check), the unit is considered to be no longer accessible. However, the 308-3 interface module will try to access the expansion unit once in each subsequent cycle. If a connection is established, data traffic is resumed. F2: * I/O modules disconnected, enable voltage missing: One or more I/O modules are not in their slots, or do not report (READY signal). This fact is also indicated by a time-out (QVZ) if the QVZ mode is activated. BASP:* Digital outputs are disabled (BASP can be output both by the CPU and by the 318-3 interface module). 0: * Bits meaningless for expansion units You will find comprehensive information on error diagnostics in the 308-3 interface module manual.
