Product Overview 1
1.1 Overview
Product Overview
The S7-200 TD devices provide a low-cost human-machine interface (HMI), allowing an
operator or user to interact with your application.
The TD devices allow you to configure a set of hierarchical user menus to provide additional
structure for the interaction with your application. You can also configure the TD device to
display alarms or messages that are enabled by specific bits in the S7-200 CPU.

Figure 1-2 Standard Keypad Configuration for the TD Devices
Dividing Information into Screens and Bit-Enabled Alarms
As shown in Figure 1-3, you can configure the TD device to display screens (which are
initiated by operator action) and bit-enabled alarms (which are initiated by the S7-200 CPU).
● Screens: You can create screens that allow the operator (using the TD device) to initiate
the interaction with the S7-200 CPU. With the TD device, you can configure a user menu
(up to 8 entries or groups for the TD 200C, TD 200, and TD400C, and up to 4 entries or
groups for the TD 100C) that provides a hierarchy for the screens. You can create up to 8
screens for each menu item or group.
● Alarms: You can create alarm messages that allow the user program in the S7-200 CPU
to initiate interaction with the operator by displaying a message on the TD device.
During the configuration of the TD device, you also designate which type of message
(screens or alarms) will be the default display mode for the TD device. After power-up, the
TD device goes to the default display mode. Also, the TD device returns to the default
display mode after a period of inactivity (if no buttons have been pressed for one minute).
Product Overview
1.5 Using the TD Device to Access Screens and Alarms
Text Display (TD) User Manual
System Manual, 08/2008, A5E00765548-03 21
Storing the Screens and Alarms in the Parameter Block
The S7-200 CPU stores the text, embedded variables, and format information for the alarms
and screens in a parameter block located in V memory. You use the Text Display wizard to
configure the starting address for the parameter block in V memory, and the Text Display
wizard allocates the memory required to store the information for the TD device.
If you configure more than one parameter block for the S7-200 CPU (with each parameter
block having a different range of addresses in V memory), you can connect several TD
devices to that one S7-200 CPU. You configure the V memory address for the specific
parameter block for each of the TD devices. The Diagnostic Menu of the TD device provides
a TD Setup command for specifying the starting address of the parameter block.
Tip
The parameter block for the TD 100C and the TD400C is not compatible with other TD
devices. The TD 100C parameter block is only compatible with a TD 100C parameter block,
and the TD400C parameter block is only compatible with a TD400C parameter block.
Displaying the Screens and Alarms on the TD Device
When the operator uses the buttons on the TD device to select a screen, the TD device
reads the screen information from the parameter block (stored in V memory of the S7-200
CPU) and displays the appropriate screen.
When you configure an alarm, you also configure an alarm bit for enabling a specific alarm.
The logic of your user program sets this alarm bit to display the alarm on the TD device.
When you create the text for the alarm, you also designate the alarm bit. If you configured an
alarm to require acknowledgement by an operator, that alarm also has an acknowledge bit.
The TD device continuously polls the alarm bits to determine which alarms have been
enabled.
To display an alarm on the TD device, your user program in the S7-200 CPU must first set
the alarm bit for the specific alarm. When your user program sets one of the alarm bits, the
TD device then reads the alarm bits in the parameter block in the S7-200 CPU and displays
the corresponding alarm message.

1.7 Creating a Custom Faceplate for the TD Device
Creating a Custom Faceplate for the TD Device
With the TD device, you can design a custom faceplate that can be layered onto any
background image. The TD 100C and the TD 200C lets you incorporate buttons (keys) of
varying size, with varying shapes, colors or fonts. The TD400C lets you incorporate buttons
(keys) of varying colors and fonts. The positions and size of the TD400C buttons (keys) are
fixed.
As shown in Figure 1-7, you use several applications to create a custom faceplate:
● Keypad Designer: Creates the layout and the configuration for the keypad
● Third-party graphics application: Designs the graphical appearance of the faceplate
● STEP 7-Micro/WIN (Text Display wizard): Configures the parameter block for the
TD 100C, TD 200C, and the TD400C
● Word-processing application (optional): Prints multiple copies of the faceplate
Siemens provides document files (in 6 languages) for Microsoft Word that help you to
align the panel images for the perforations on the A4 blank faceplate material. To open
these documents, browse to the Templates subdirectory under the Keypad Designer
application (C:/Program Files/Siemens/TD Keypad Designer/Templates) and select the
template for your TD device and language.

1.8 Printing the Custom Faceplate for the TD device
Printing the Custom Faceplate for the TD Device
The TD 100C and the TD 200C ship with one blank faceplate (envelope-size) for printing the
faceplate. The faceplate is constructed from durable, polyester material which has been
designed especially for use on HMI faceplates.
The TD400C does not include a blank faceplate. You can either order blank faceplates, or
use the Keypad Designer to print a TD400C custom faceplate on A4 paper and take it to a
local supplier to make a custom TD400C faceplate.
● You can print a single faceplate directly from the Keypad Designer on the envelope-sized
blank faceplate.
● To print multiple faceplates, you can use the Microsoft Word template (provided in the
Templates subdirectory) that ensures your faceplate design is properly sized. You can
print multiple faceplates onto the perforated A4-size blank faceplate sheets.
Refer to Chapter 3 for specific information about printing the custom faceplate for your TD
device.
Tip:
The faceplate material is specially treated on one side to accommodate printing with a laser
printer. The treated surface is up (or toward you) when you are holding the material with the
cut corner in the top right of the sheet.
Ensure that the material is correctly inserted into the laser printer so that the faceplate prints
the reversed image onto the treated surface of the material. You must print a reversed-image
version of the faceplate onto the faceplate material.
Before printing your custom faceplate onto the blank faceplate sheet, first test your design by
printing the faceplate onto regular paper. You can then temporarily use the paper faceplate
to test the functionality of the design with your TD device.
Printer Requirements
To print your custom-designed image onto the blank faceplate material, you must use a laser
printer that supports the following features:
● Paper size: The laser printer must be able to print on both the A4 (210 mm X 297 mm)
and envelope formats.
● Color: The laser printer must support color printing.
● Transparencies: The laser printer must support the printing of transparencies (or other
non-paper stock)
Ordering Additional Faceplate Material
You can order additional blank faceplates for the TD 100C, TD 200C, and TD400C device in
perforated A4-size sheets (10 sheets/package). The faceplate material is especially
designed for printing on a laser printer. The blank faceplate sheets also allow you to utilize
the services of professional printing vendors that specialize in laser printing in order to create
large quantities of high-quality faceplates.

2.6 Installing a Faceplate for the TD 100C, TD 200C and TD400C
Installing a Faceplate for the TD 100C, TD 200C, and TD400C
The TD 100C and TD 200C ship with a blank faceplate (envelope size) for creating a
custom-designed faceplate. The TD400C does not ship with a blank faceplate; you can order
a package with blank faceplates (see appendix A for order information).
The TD devices do not ship with the faceplate attached. The front of the TD is an adhesive
surface (shipped with a protective paper) that allows you to attach your custom faceplate.
Refer to Chapter 3 for information about designing and printing a custom faceplate.
The figure below shows the dimensions for the faceplate of the TD devices. Blank faceplate
material for the TD 100C, TD 200C and TD400C is available in the sizes shown below.
● Envelope size for printing a single faceplate (TD 100C, TD 200C only)
● A4 size (210 mm x 297 mm) for printing multiple copies of the faceplate (TD 100C, TD
200C, and TD400C)
You must cut the faceplate from the envelope-sized material, but the A4 material is
perforated to allow you to remove the faceplates without cutting.
Use the following procedure to install your custom faceplate on the TD device. The example
shown here is for the TD 200C. Installing a faceplate on a TD 100C and TD400C is similar;
the differences are noted below. To prepare for installation, remove the protective film
covering the display window of the TD device and the back of the preprinted (standard)
faceplate. The protective film is blue for the TD 100C and the TD 200C, and is transparent
for the TD400C.
1. The dimensions for the custom faceplate are shown for the TD device.
2. If your TD device has a strip of protective paper, remove the strip to expose the strip of
the adhesive. For the TD 200C and the TD400C, it is on the left side of the device. For
the TD 100C, it is on the right side of the device.
3. Carefully align your custom faceplate on the entire TD device, and then seal the faceplate
to the exposed adhesive by pressing down on the left (TD 200C and TD400C) or on the
right (TD 100C) side of the faceplate.

2.7 Connecting the TD/CPU Cable
Connecting the TD/CPU Cable
NOTICE
Operating the TD device with an ungrounded voltage source can damage the TD device.
The TD device may only be connected to grounded voltage sources. Non-grounded
operation can cause the TD device to become damaged.
Always ensure that the voltage source for the TD device is properly grounded.
The TD devices can use the TD/CPU cable for communicating with the S7-200 CPU.
● You can connect the TD device directly to the S7-200 CPU, creating a one-to-one
network configuration. In this configuration, one TD device connects to one S7-200 CPU
through the TD/CPU cable.
● You can connect multiple TD devices to multiple S7-200 CPUs over a network. The TD
device defaults to address 1 and attempts to communicate to a CPU at address 2.
For more information about connecting to multiple CPUs, see Appendix B. For information
about changing the default addresses in the TD device, see Chapter 5.
If you require a longer cable (>2.5 m) to connect the TD device to the S7-200 CPU, use
PROFIBUS components for the network connection. Refer to the SINEC IK10 Catalog.

2.8 Supplying Power for the TD Device
Supplying Power for the TD Device
The S7-200 CPU uses the TD/CPU cable to provide power to the TD device. Use this type of
power supply when the distance between the TD device and the S7-200 CPU is less than
2.5 m (the length of the TD/CPU cable). The TD 200, TD 200C and the TD400C have the
option of using an external power supply.
Tip
The TD 100C device must use the TD/CPU cable to provide power from the S7-200 CPU to
the TD device. The TD 100C does not have the option of using an external power supply.
Tip
If the distance between the TD 200, TD 200C or TD400C and the S7-200 CPU is greater
than 2.5 m, use an external 24 VDC power supply.
If you require a longer cable (greater than 2.5 m) to connect the TD device to the S7-200
CPU, use PROFIBUS components for the network connection. Refer to the SINEC IK10
Catalog.
Refer to Appendix B for information about using the TD device on a network.
As shown in the figure below, the TD device provides up to two options for providing power:
● The TD/CPU cable allows the S7-200 CPU to provide power to the TD device over the
communications port. This is the only option available for the TD 100C.
For information about the TD/CPU cable and the communications port, refer to
Appendix B.
● You can connect the TD 200, TD 200C or the TD400C to an external power supply.
The TD 200, TD 200C or TD400C requires 120 mA at 24 VDC to operate. An optional

Establishing a Connection for Your TD Device
As described in Chapter 4, you use the Text Display wizard of STEP 7-Micro/WIN to
configure the screens, alarms, languages, and custom keypad layout for the TD 100C,
TD 200C and the TD400C. The S7-200 CPU stores this information in a parameter block (V
memory).
The TD devices ship with a default configuration and are set to communicate at a rate of
9600 baud. The TD devices must communicate with the S7-200 CPU to be able to read the
parameter block.
You must configure your TD device to communicate at the same baud rate as your S7-200
CPU.
TD 100C, TD 200C, and TD400C
Until the TD device successfully connects to the S7-200 CPU and reads the parameter
block, the TD device remains configured for the standard TD keypad shown in the figure
below.
To change the baud rate of your TD device, you use the ESC and ENTER buttons to
navigate to the Diagnostic/TD Setup Menu and change the TD Setup parameters. (See
Chapter 5.) Because the TD devices ship with no faceplate attached, it may be difficult to
consistently press ESC or ENTER.
The TD 100C, TD 200C, and TD400C devices ship with a faceplate for the standard TD
keypad. In addition, the Keypad Designer provides a sample faceplate for the standard TD
keypad in the following directory.
C:/Program Files/Siemens/ TD Keypad Designer/Templates
For temporary use, you can print this faceplate onto paper and lay the paper on top of the
TD device (without removing the covering from the adhesive).
Refer to Chapter 3 for information about opening the Keypad Designer and printing a
faceplate.

3.3 Starting the Keypad Designer
Starting the Keypad Designer
You use the Keypad Designer application to create a custom-designed layout for the keypad
of the TD 100C, the TD 200C, or the TD400C.
When you install STEP 7-Micro/WIN, you also install the Keypad Designer application. The
Keypad Designer does not require STEP 7-Micro/WIN.
You can start the Keypad Designer either from within STEP 7-Micro/WIN or as a stand-alone
application:
● To start as a stand-alone application: Select the Start > SIMATIC > TD Keypad Designer
menu command
● To start from STEP 7-Micro/WIN: Click the Keypad Designer icon in the Tools window
The Keypad Designer application opens with a blank keypad template. The TD 200C and the
TD400C templates are shown in the figures below.. Select File > New to create a new
keypad layout for either the TD 100C, the TD 200C, or the TD400C. In the Keypad Designer
Type dialog, select the keypad type.
To open an existing project, select the File > Open menu command and browse to the
project.

If you open a file with different target (for example, you are working on a TD 200C file, and
you open a TD 100C file), the panel workspace resizes for the new target. Since the
application is sized based on the panel workspace, you may have to resize and re-position
your application framework.
Table 3-1 describes the files that are used by the Keypad Designer.
You can change the language of the Keypad Designer by selecting the Tools > Options
menu command. You select the language from the Options dialog shown below.

Adding Buttons to the Keypad
The TD 100C and the TD 200C allow you relative freedom when designing your keypad.
With the TD400C, the position and size of the buttons are fixed. You cannot add, remove, or
change the TD400C buttons.
On the TD keypad you can configure up to 20 buttons for the TD 200C, up to 14 buttons for
the TD 100C, and up to 15 buttons for the TD400C.
● You can vary the size and the location of the buttons (TD 100C and TD 200C only)
● You can define the functionality for each button.
The Keypad Designer provides a grid that aligns the location of the buttons with the physical
keypad of the TD device.

Inserting a Button
With the TD 100C and the TD 200C, you can add a button to the keypad grid. The TD400C
does not have this option.
1. Click the Draw Button icon.
2. Move the cursor over the grid.
3. Move the cursor (and button) into position on the keypad grid.
4. Hold down the left mouse button and drag the cursor to adjust the size and shape of the
button.
5. Release the mouse button to insert the button onto the keypad
After you have inserted the button onto the keypad grid, you can relocate the button by
dragging it to a new location on the grid. However, you cannot resize the button.
Figure 3-7 Adding a Button (TD 100C and TD 200C)
Modifying the Shape of a Button
With the TD 100C and the TD 200C you can modify the shape of a button. The Keypad
Designer provides two methods for modifying the shape of a button. The TD400C does not
have this option.
● Changing the size or shape of a button by adding a second button on top of the first
button
● Erasing a portion of the button
Extending the Shape of a Button
You cannot resize a button that has been inserted onto the keypad grid. However, with the
TD 100C and the TD 200C, you can insert a second button on top of the first button to create
a new size for the button. The TD400C does not have this option.
As shown in the figure below, adding a second button also allows you to create buttons of
non-rectangular shape (combining the shapes of both buttons).
When you insert the second button, ensure that the cursor is within the boundaries of the
first button.

3.5 Defining the Properties of the Button
Text Display (TD) User Manual
System Manual, 08/2008, A5E00765548-03 53
The TD400C has up to 15 buttons that can be defined. You do not have to define (or use) all
the buttons. Some buttons can be blank or unused.
Table 3-2 describes the functions that you can configure for the button. The default function
is to set a bit in the S7-200 CPU (Set PLC Bit).
Some functions can also be used in combination with other buttons, such as SHIFT or the
arrow buttons. The Properties dialog provides suggestions for appropriate buttons for
combining the functions.
After you configure the functions for each button on the keypad, select the File > Save or the
File > Save As menu command to create the configuration file (*.td2 for the TD 200C, *.td1
for the TD 100C, or *.td4 for the TD400C).
Tip
A button that has been configured will display the button name on the button in the panel
layout.

Exporting the Keypad Layout to a Graphics Application
After you have configured the buttons on the keypad, you can create the graphical
representation for the faceplate. You can use any third-party graphics application to add
colors, lines and other artwork to the panel design.
The Keypad Designer exports the layout of the buttons as a bitmap file (*.bmp) that you edit
with the graphics application.
As shown in the figure below, the button template provides a bitmap image of the layout of
the keypad that you can use with your graphical application to position, size and align the
graphical elements of your faceplate design. These elements can include logotype, text, or
other images.
The Keypad Designer allows you to export the layout of the buttons into your graphics
application. Use the File > Export >Button Template to File menu command to create a
bitmap file (*.bmp) that you insert into the graphics application.
After you customize the layout (adding background image, colors, buttons or logotype), you
save the file as a bitmap (*.bmp). This bitmap becomes the panel image for the Keypad
Designer.

3.7 Adding a Panel Image to the Faceplate
Adding a Panel Image to the Faceplate
Using your own graphics application, you create the following graphical elements for the
faceplate of the TD 100C, TD 200C, or the TD400C:
● Button images
● Background image or color scheme
● Text (for the buttons or the background)
● Logotypes (and other images or text)
For the TD 100C and the TD 200C, you are not required to use square buttons. However,
you must ensure that your button design covers the area of the button as defined in the
button template.
After you have used your graphics application to modify the panel image for the faceplate,
save the design as a bitmap file (*.bmp).

3.8 Saving the Keypad to a TD Configuration File
Text Display (TD) User Manual
58 System Manual, 08/2008, A5E00765548-03
Tip
When you design your faceplate, you can create the bitmap with any resolution. However,
the size of the background image for the TD device must exactly match the following
dimensions:
● For the TD 200C:
Width: 137 mm (+/- 0.15 mm) (5.42 inches)
Height: 65.7 mm (+/- 0.15 mm) (2.58 inches)
● For the TD 100C:
Width: 79 mm ((+/- 0.1 mm) (3.11 inches)
Height: 65.8 mm (+/- 0.1 mm) (2.59 inches)
● For the TD400C:
Width: 91.5 (+/- 0.1 mm) (3.6 inches)
Height: 163.5 (+/- 0.1mm) (6.44 inches)
If your faceplate design does not match these dimensions, the Keypad Designer alerts you
before importing the panel image. If you import a panel image with incorrect dimensions, the
Keypad Designer resizes your panel image, which could distort the appearance of your
faceplate design.
3.8 Saving the Keypad to a TD Configuration File
Saving the Keypad to a TD Configuration File
When you save the keypad, you create a TD configuration file (*.td1 for the TD 100C, *.td2
for the TD 200C, and *.td4 for the TD400C). This file contains the following information about
the buttons on the keypad:
● Number of buttons
● Location and sizes of the buttons
● Names of the buttons
● Functions assigned to the buttons
● Panel image (if one was imported)
Use the File > Save or File > Save As menu command to save the configuration of the
keypad.
The Text Display Wizard uses this information for configuring the TD 100C, TD 200C, or
TD400C. See Chapter 4 for more information.

Figure 3-16 Saving the TD Configuration File
Tip
The Keypad Designer allows you to save invalid or incomplete configurations. This allows
you to save interim versions of your work. However, always ensure that the final
configuration of the keypad is valid and complete before using the configuration file (*.tdx)
with the Text Display wizard.
3.9 Reversing the Panel Image
Reversing the Panel Image
The Reverse Panel Image option only affects the way that the panel image is saved to a file
using the File > Export > Panel Image to File menu command. The exported bitmap file can
then be inserted into the Microsoft Word template. For more information see the next
section, Printing the Panel Image on a Faceplate. The Reverse Panel Image option does not
change the layout of the keypad.
● Printing a reversed image allows you to orient the side of the faceplate with the ink from
the printing process towards the TD device. The operator then touches only the plastic
membrane and not the ink when pressing a button. See the figure below..
● Printing a non-reversed panel image allows the elements to be read correctly when
printed. Use the non-reversed panel image when you print a paper copy of the faceplate
for review. See figure below.
Use the File > Export > Reverse Panel Image menu command to select this function. A
check mark notifies you that Reverse Panel Image function is selected.

3.10 Printing the Panel Image on a Faceplate
Printing the Panel Image on a Faceplate
To print your custom-designed panel image onto the blank faceplate material, you must use
a laser printer that supports printing transparency material in both the A4 and envelope
formats and also supports color printing.
● You can print a single panel image directly from the Keypad Designer on the envelope-
sized blank faceplate (shipped with the TD 100C and TD 200C device). When you print a
single faceplate (File > Print), the panel image is always reversed.
● To print multiple panel images, you can use the Microsoft Word template that ensures
your panel image design is properly sized. You can print multiple panel images onto the
perforated A4-size blank faceplate sheets. See Appendix A for order numbers.
Tip
The faceplate material is specially treated on one side to accommodate printing with a laser
printer. The treated surface is up (or toward you) when you are holding the material with the
cut corner in the top right of the sheet.
Ensure that the material is correctly inserted into the laser printer so that the panel image is
printed onto the treated surface of the material. You must print a reversed-panel image
version onto the faceplate material. To reverse the panel image, see the previous section,
Reversing the Panel Image.
Before printing your panel image onto the blank faceplate sheet, first test your design by
printing the panel image onto regular paper. You can then temporarily use the paper
faceplate to test the functionality of the design with your TD device.
Using the blank faceplate sheets also allows you to create large quantities of high-quality
faceplates by utilizing the professional printing services of shops that specialize in laser
printing.

You can order additional blank faceplates in perforated A4-size sheets (10 sheets/package)
for the TD 100C, TD 200C and TD400C. The faceplate material is especially designed for
printing with laser printers.
The blank faceplate material for the TD 100C, TD 200C and TD400C is available in the sizes
below:
● Envelope size for printing a single faceplate (TD100C, TD200C): The Keypad Designer
prints registration lines for trimming the faceplate to the correct dimensions. (Use a metal
straight edge and a knife or razor blade to ensure accurate and straight cuts.) The
TD 100C and TD 200C devices ship with a single blank faceplate. The TD400C does not
include a single faceplate.
● A4 size (210 mm x 297 mm) for printing multiple copies of the faceplate (TD100C,
TD200C, and TD400C): You can use the Microsoft Word template to print the faceplate
onto perforated areas of the material. You do not have to cut the faceplates from the
material. Order these A4 sheets from your Siemens distributor. See Appendix A for order
numbers.

Tip
Before attempting to print a custom faceplate, ensure that both the printer and the word-
processing application are set to the correct paper size:
● Single-copy sheet: Set both the printer and word-processing application to print on
Envelope.
● Multiple-copy A4 sheet: Set both the printer and the word-processing application to print
on A4-size paper.

3.10 Printing the Panel Image on a Faceplate
Text Display (TD) User Manual
62 System Manual, 08/2008, A5E00765548-03
Your computer and your laser printer may have other settings that cause the printer to scale
the faceplate to an incorrect size. Always first print a test copy on paper before printing your
faceplate onto the blank material.
Printing a Single Faceplate from the Keypad Designer
You can print individual faceplates directly from the Keypad Designer:
1. Ensure that the laser printer is set to print envelopes.
2. Insert the envelope-size faceplate material into the tray.
3. Select the File > Print menu command.
4. Select the laser printer and click OK.
5. Using the cut lines and a paper cutter, cut the faceplate from the material
Figure 3-20 Printing a Single Faceplate
Tip
For best results use a razor-blade cutting knife with a metal straight edge to cut the faceplate
from the material. You can also use a high-quality paper cutter. Be especially careful when
using scissors or similar tools. Scissors are more likely to stretch or tear the material,
causing irregular edges for the faceplate.
Printing the Faceplate from a Word-Processing Application
You use a word-processing application (such as Microsoft Word) to print multiple copies of
the faceplate onto A4-size blank faceplate material. After you export the panel image of the
faceplate into a document, you adjust the location of the panel images and print the
document.
Tip
Siemens provides document files (in 6 languages) for Microsoft Word that helps you to align
the panel images for the perforations on the A4 blank faceplate material. To open these
documents, browse to the Templates subdirectory under the Keypad Designer application
(C:/Program Files/Siemens/TD Keypad Designer/Templates) and select the template for
your TD device and language.
Before printing the faceplate onto the blank faceplate material, you must ensure that the
document and the printer settings are both set to print on A4 paper. Also, ensure that the
laser printer itself is configured to print A4 paper.
After you print the faceplate document, you use the perforations to remove the faceplates
from the sheet.

To export the panel image to your word-processing application:
1. Open your word-processing application (Microsoft Word) and open the template file.
2. Open the Keypad Designer
3. In the Keypad Designer, select the File > Export > Panel Image to File menu command to
create a bitmap file that you insert into the word-processing application.
4. Insert the panel image into the document by using the word-processing application to
insert the bitmap file (*.bmp) that you created with the Keypad Designer.
5. Follow the instructions in the template file for positioning and sizing the faceplate.
6. After inserting the panel image into the document, save the document using the File >
Save As menu command of the word-processing application.
With the panel images saved in your document, you can print the document to your laser
printer.
Tip
Before printing the panel image onto the blank faceplate material, first test your design by
printing the faceplate onto regular A4 paper.

3.11 Installing the Printed Faceplate onto the TD device
Installing the Printed Faceplate onto the TD 100C, TD 200C, and TD400C
Use the following procedure to install your custom faceplate on the TD device. The example
shown here is for the TD 200C. Installing a faceplate on a TD 100C and TD400C is similar;
the differences are noted below. To prepare for installation, remove the protective film
covering the display window of the TD device and the back of the preprinted (standard)
faceplate. The protective film is blue for the TD 100C and the TD 200C, and transparent for
the TD400C.
1. If your TD device has a strip of protective paper, remove the strip to expose a strip of the
adhesive. For the TD 200C and TD400C, it is on the left side; for the TD 100C, it is on the
right side of the device.
2. Carefully align your custom faceplate on the entire TD device, and then seal the faceplate
to the exposed adhesive by pressing down on the left (TD 200C and TD400C) or on the
right (TD 100C) side of the faceplate.
3. Carefully lift back the unadhered faceplate and remove the rest of the protective paper
from the TD device.
4. Carefully position the faceplate onto the TD device. Firmly press the faceplate onto the
adhesive, taking care to remove any air bubbles that may have been trapped underneath.
NOTICE
Do not use excessive force or a hard (or sharp) tool when you install the faceplate onto
the TD400C device.
If you use excessive force a hard tool when you press the faceplate onto the TD400C
device, it may cause damage to the springs under the faceplate.
Ensure that excessive force or a hard (or sharp) tool is not used when you install the
faceplate onto the device
Refer to Chapter 2 for additional information about installing the TD devices, including the
dimensions for the faceplate.

4.1 Overview
Overview of Chapter 4
You do not configure or program the TD device. The Text Display wizard creates a
parameter block that stores the configuration, screens and alarms for the TD device. The S7-
200 CPU stores the parameter block in V memory. At power-up, the TD device reads the
parameter block from the S7-200 CPU.
You use the Text Display wizard of STEP 7-Micro/WIN to perform the following tasks:
● Configuring the parameters for the TD device
● Creating the screens and alarms to be displayed on the TD device
● Creating the language sets for the TD device (TD 200, TD 200C and TD400C only)
● Assigning the V memory address for the parameter block
Tip
To connect your TD device to a network, you use the Diagnostic or TD Setup Menu of the
TD device to set up the network addresses, baud rate and other parameters. Refer to
Chapter 5.
4.2 Overview of the Configuration Tasks
Overview of the Configuration Tasks
The S7-200 CPU stores the configuration data for the TD device, including the screens and
alarms, into a parameter block (located in V memory). The Text Display wizard creates the
parameter block. When you download your project (user program and data block) to the S7-
200 CPU, you also download the parameter block as part of the data block.
You do not configure or program the TD device. At power-up, the TD device reads the
parameter block from the S7-200 CPU.
As shown in the figure below, you use the Text Display wizard of STEP 7-Micro/WIN to
create the parameter block for the TD devices. The next figure shows the sequence of the
tasks required for configuring the parameters of the TD device.

Selecting a Password for the TD Device
Selecting a password for the TD device helps you to protect the security of your process or
application. By enabling a four-digit password (from 0000 to 9999), you can control access to
the S7-200 CPU by requiring that an operator enter the password before editing variables
from the TD device.
The TD password also restricts access to the following TD functions:
● Set time and date
● TD Setup
● Forcing I/O
● Changing the CPU mode
● Creating a memory cartridge
● Editing CPU memory
Tip
The TD password affects only the ability of an operator to use the TD device for certain
functions.
If your S7-200 CPU is configured to require a password, the operator must enter the CPU
password to force I/O and create a memory cartridge. The TD password is used in addition
to the CPU password.

You can select how often the TD device performs a read operation to update the information
from the S7-200 CPU. You can select from "As fast as possible" to "Every 15 seconds" (in
one-second increments).
Selecting the Language and the Character Set
The Text Display wizard allows you to select the language for the system menus and
prompts of the TD device. This selection does not affect the language setting for the screens
or alarms that you enter. You select a character set that supports the language of the text
that you enter for the screens and alarms. (If the character set does not match the Windows
character set, the Text Display wizard may not display the characters correctly. The TD
device displays these characters correctly.)
● Select the language for the system menus and prompts displayed by the TD device.
The TD devices support English, French, German, Italian, Simplified Chinese, and
Spanish.
● Select the character set for the text in your alarms and screens.
Refer to Appendix A for descriptions of the character sets supported by your TD device.
The Simplified Chinese Character Set is an electronic file that resides on the STEP 7-
Micro/WIN documentation CD
These settings define a language set for the TD device. The Text Display wizard also
provides a series of dialogs for copying the alarms and screens to create additional language
sets (TD 200, TD 200C, and TD400C). For each language set, you select the language and
the character set.

76 System Manual, 08/2008, A5E00765548-03
Tip
When you create multiple language sets (TD 200, TD 200C, and TD400C), the Text Display
wizard copies the alarms and screens from the primary language set to the other language
set. You then edit the screens and alarms to translate the text displayed for the new
language set.
If you need to modify the screens or messages (such as to add a new variable or to add a
new alarm), you must edit the primary language. The Text Display wizard copies these
changes to the other language sets.
The Text Display wizard only allows you to change the text in the other language sets.
Selecting the Font Size (TD 100C, TD400C)
The TD 100C and TD400C support two font sizes for displaying user and alarm messages.
Larger fonts are easier to read, but will result in fewer characters per user message. You
select the font size for the TD100C as shown in the figure below. You select the font size for
the TD400C when you configure the alarm or user message (refer to the section on
configuring screens and alarms in this chapter).
The following font sizes are available:
● TD 100C:
Small font (16 ASCII or 8 Chinese characters per line)
Large font (12 ASCII characters per line)
Font selection applies to all messages and screens
● TD400C:
Small font (24 ASCII or 12 Chinese characters per line)
Large font (16 ASCII or 8 Chinese characters per line)
Each alarm or screen can have a different font

The TD 100C, TD 200C, and TD400C allow you to create a custom keypad. As described in
Chapter 3, you can insert buttons onto the keypad. The Keypad Designer saves this
configuration to a file (*.td1 for the TD 100C, *.td2 for the TD 200C, and *.td4 for the
TD400C).
To load the keypad configuration file into the Text Display wizard:
● Select the option, Use a custom keypad created with the Keypad Designer. (Find this
check box in the Options area of the Configure Keypad Buttons dialog. See Figure
below.)
● Browse to the keypad configuration file (*.tdx) that you created with the Keypad Designer.
The Text Display wizard loads the keypad configuration file and updates the table of buttons
and the button symbols.
The Text Display wizard lists only those buttons that you had defined with the Set Bit
functionality when you created the buttons with the Keypad Designer.

Figure 4-12 Configuring the Functions for the Buttons (TD400C)
Configuring the Buttons on the Keypad
As shown in previous figure, the Configure Keypad Buttons dialog allows you to select a
symbol name and an action for each of the configurable buttons on the TD device.
● The TD 200 keypad provides 4 configurable buttons and a SHIFT button that can be
configured for up to 8 bits in the S7-200 CPU
● The TD 200C can be configured for up to 20 configurable buttons
● The TD 100C can be configured for up to 14 configurable buttons
● The TD400C can be configured for up to 15 configurable buttons
Tip
The Configure Keypad Buttons dialog of the Text Display wizard displays only those buttons
that set bits in the S7-200 CPU. The Text Display wizard does not list the buttons with other
functionality, such as ESC or SHIFT.
The symbols that you assign to the buttons on the keypad allow the logic of your user
program in the S7-200 CPU to interact with the TD device. (The Text Display wizard
suggests a symbol for these buttons. You can accept the recommendation or enter a new
symbol for the button.)
For each button, you configure the type of action:
● Set bit: When you press the button on the TD device, the TD device sets the bit on in the
S7-200 CPU. The bit stays on until the logic of your user program in the S7-200 CPU
resets the bit.
● Momentary contact: When you press the button on the TD device, the TD device sets the
bit on in the S7-200 CPU. When the TD device button is released, the TD device turns
the bit off in the S7-200 CPU.

Tip
The TD device only sets the bit on or off in the S7-200 CPU a single time when the TD
device button is either pressed or released.
Tip
The TD device can display a special icon that provides visual feedback to the operator and
shows that the set bit key was pressed in the CPU. To enable this feature, check the box at
the bottom of the Configure Keypad Buttons wizard screen (see the previous figure).
4.4 Configuring the Screens for the Text Display Device
Configuring the Screens for the TD Device
The TD device supports a set of user-defined screens and a user menu. Screens allow the
operator using the TD device to initiate the interaction with the S7-200 CPU. See the figure
below.
● User menu: Provides a hierarchy for switching between groups of screens. For the
TD 200, TD 200C, and the TD400C you configure up to 8 entries in the user menu. For
the TD 100C, you configure up to 4 entries in the user menu.
● Screens: You create up to 8 screens for each entry in the user menu.
The TD device displays the screens and the items on the user menu in the order that you
configure them.
If you configure both alarms and screens, you also designate the default display mode for
the TD device.
The operator uses the buttons on the keypad to navigate through the user menu or the
screens that you configured.

Tip
For the TD 200, TD 200C, and the TD400C, you can embed up to 6 variables per screen.
For the TD 100C, you can embed up to 1 variable per line (4 variables per screen).
● Data address:
– VB: Numeric String, Text String
– VW: Signed, Unsigned
– VD: Real, Signed, Unsigned
● Data Format: Signed, Unsigned, Real, Numeric String, or Text String
● Digits to the right of the decimal: Up to 7
Figure 4-19 Inserting PLC Data
The TD device rounds a real number to the specified decimal place. For example, if the real
number value is 123.456 and you select 2 digits to the right of the decimal, the TD 200
displays this value as: 123.46.
Tip
Refer to the SIMATIC S7-200 Programmable Controller System Manual for information
about the data types or for the memory addresses supported by the S7-200 CPU.
You can also allow the operator to modify the data stored at this memory location in the S7-
200 CPU.
● You can require the operator enter the TD password before editing the variable. (You
must have enabled password-protection for the TD device.)
● You can configure the cursor to jump to the variable field.
● You can define a symbolic name for the variable. You use the symbolic name to access
this data with your user program.
Clicking OK inserts the variable into the text of the screen. The Text Display wizard inserts a
block of 4 characters to show the presence of the variable. The value to be displayed for the
variable is right-justified at that location (anchored to the right-most character).
Data values are always right-justified to the right-most character of an embedded variable.
As a data value grows in magnitude, it utilizes more spaces to the left of the anchor point
and can overwrite the text characters. Always provide sufficient space between the end of
your text and the anchor point to allow for the expected range of the data value.

Tip
The actual number of characters used to display a value varies with the size of the value. To
help calculate the number of characters required for displaying the value of the variable, see
the examples listed in Table 4-1.
The TD device displays all values as decimal numbers. Positive signed values are displayed
without a sign, and negative signed values are displayed with a leading minus sign.
Unsigned values are displayed without a sign. A leading zero is used for all fractional
numbers (for example, 0.5). Real numbers are displayed with the number of decimal places
you specify. The value is rounded to the specified decimal place.

1 The length of a line (number of characters in a line) varies by TD model and character size. The line
length is always 20 for a TD 200 or TD 200C. The line length is either 12 or 16 characters for a
TD 100C. The line length for the TD400C depends on the font you selected. If you selected a small
font, you have 24 ASCII characters or 12 Chinese characters per line. If you selected a large font,
you have 16 ASCII characters or 8 Chinese characters per line.
Embedded String Variables
There are special considerations when you set up a string variable for the TD devices. String
variables are positioned the same as numeric variables, that is, the right-most character of
the variable is positioned at the right-most position of the embedded variable in the Text
Display wizard. This can cause problems when you want to place a text string adjacent to
other text in the message.
Using the Text Display Wizard to Configure the S7-200 CPU for Your Text Display (TD) Device
4.4 Configuring the Screens for the Text Display Device
Text Display (TD) User Manual
86 System Manual, 08/2008, A5E00765548-03
When you embed a string variable in a TD alarm or screen, the Text Display wizard shows
the embedded variable occupying 4 character spaces (or 2 Chinese characters) for the
variable. These 4 spaces are the right-most 4 characters of the text string. If you want to
have the text adjacent to other text, that is, to the left of the variable, the characters in the
string need to be left-justified and padded with spaces to place the text in the proper position
on the display.
For example: Assume that we want to show the pump status and that status is either "Pump
OK" or "Pump High Temp". The screen display shows the word "Pump" followed by a string
variable which is set to either "OK" or "High Temp". You set up the display in the Text
Display wizard like this:
Pump _ _ _ _ _ _
The underlines are blank spaces, and the squares are the embedded variable (which takes
up 4 character spaces). You can create 2 strings that you copy into the variable based on
the current pump status. These strings are "OK" and "High Temp". These strings are
displayed in the figure below.
3XPS+LJK7HPS RU 3XPS2.
Figure 4-20 Embedded String Variable
The right-most character of the "OK" string is placed in the right-most position of the
embedded variable. Since the string is only 2 characters, it displays on the right side of the
display where the embedded variable is placed.
To make the "OK" string display next to "Pump", simply add blank spaces to the "OK" string
to match the length of the other string. The "OK" string would become "OK ". Now the string
is displayed in the figure below.
3XPS2.
Figure 4-21 Embedded String Variable with Blank Spaces
The figure below shows how to create the two strings using the STR_CPY command. Note
how the "OK" string is padded with blank spaces to left justify the characters on the TD
display.

Configuring the Alarms
Alarms allow the user program in the S7-200 CPU to initiate interaction with the operator by
displaying an alarm message on the TD device. When your user program sets an alarm bit,
the TD device reads the text of the alarm from the S7-200 CPU.
The figure below lists the key tasks for creating alarms. You configure the following
information for each alarm:
● Number of alarms: Up to 80 alarms for the TD 200, TD 200C and TD400C, and up to 40
alarms for the TD 100C to be configured for the TD device
● Text message for the individual alarms

4.5 Configuring the Alarms
Text Display (TD) User Manual
System Manual, 08/2008, A5E00765548-03 89
Determining the Type of Operator Interaction for an Alarm
The Text Display wizard allows you to determine the type interaction required by the
operator for an alarm. If the user screens are set as the default display mode for the TD
device and an alarm is enabled, an alarm indicator will begin to flash on the TD display. The
indicator is large if there is an alarm enabled that requires acknowledgement. The indicator
will be small if the alarms do not require acknowledgement. The user can switch to the alarm
display to view the alarms.
The alarm display will show one or more alarms in priority order. An UP or DOWN arrow in
the right-most character position indicates more alarms are active, but not visible on the
display. The operator can press either the UP or the DOWN arrow key to scroll through the
other enabled alarms.
The operator can edit or accept variable values by pressing the ENTER key. The TD device
will write the updated variable value to the CPU and set the edit notification bit for that
variable when the operator presses the ENTER key. The TD device then moves the cursor
to the next editable variable. Pressing ENTER for the last editable variable of an alarm writes
this last value to the S7-200 CPU and the TD device then resets the alarm enable bit. For
more information on editing variables, see Editing a Variable that is Embedded in an Alarm
or a Screen in Chapter 5.
Every alarm falls into one of four possible alarm acknowledgement and editing types. This
section explains specifically how each alarm type is handled by the TD device. The four
alarm types follow:
● No acknowledgement required, no edits allowed
● Acknowledgement required, no edits allowed
● No acknowledgement required, edits allowed
● Acknowledgement required, edits allowed
No Acknowledgement Required, No Edits Allowed
In this combination of no acknowledgement required and no edits allowed, the TD device
simply displays the alarm. The ENTER key has no function since there are no editable
variables within the alarm. The alarm may contain variables that are updated at the update
rate of the TD device. This type of alarm is replaced on the display if a higher priority alarm is
enabled by the S7-200 CPU. The operator can either press the UP or the DOWN arrow key
to scroll to other alarms or press ESC to return to the menus.
The TD device does not clear the corresponding alarm-enable bit in the S7-200 CPU.
Acknowledgement Required, No Edits Allowed
In this combination of acknowledgement required and no edits allowed, the TD device
displays the alarm and makes the entire alarm flash (blink) until the operator presses ENTER
to acknowledge the alarm. Variable values are updated from the S7-200 CPU at the normal
update rate while the alarm is flashing.
When the operator presses ENTER, the TD device:
● Sets the acknowledgement-notification bit for this alarm.
● Clears the alarm-enable bit for this alarm. This causes the alarm to be removed from the
display on the next update cycle.

4.5 Configuring the Alarms
Text Display (TD) User Manual
90 System Manual, 08/2008, A5E00765548-03
Another alarm cannot replace the one flashing until the operator acknowledges the flashing
alarm. This is also true even if a higher priority alarm is enabled in the S7-200 CPU. If the TD
device is configured for single line alarms and the CPU enables a higher priority alarm, the
flashing alarm shifts down to the next line of the display. The operator cannot press the UP
or the DOWN key to scroll through other enabled alarms until the current alarm is
acknowledged.
No Acknowledgement Required, Edits Allowed
In this combination of no acknowledgement required and edits allowed, the TD device
displays a alarm and then waits for the operator to edit a value in the alarm. All of the
variables within the alarm are updated at the update rate. Since the alarm does not require
acknowledgement, this type of alarm is removed from the TD device display if a higher
priority alarm is enabled in the S7-200 CPU.
Acknowledgement Required, Edits Allowed
In this combination of acknowledgement required and edits allowed, the TD device displays
the alarm, causes the entire alarm to flash (blink), and then waits until the operator
acknowledges the alarm and edits or accepts the values in the alarm. This type of alarm
requires that the operator edits or accepts the values displayed in the alarm. If the operator
aborts the edit by pressing the ESC key before editing all the values in the alarm, the alarm
flashes to indicate that edits are still required.
When the alarm is enabled in the S7-200 CPU, the TD device notes this and, if there is
space available on the display, reads the alarm from the CPU. The TD device then displays
the alarm and causes the entire alarm to flash to notify the operator that the alarm is present
and must be acknowledged.
Setting the Default Display Mode and Alarm Parameters
The TD device supports alarms that are displayed under program control. After you have
configured the TD device, you can configure the alarms. When you configure the alarms, you
also select either screens (default) or alarms as the default display mode for the TD device.
Click the Alarms icon to start creating alarms. As shown in the figure below, you select the
following information:
● Default display mode: Select either alarms or screens as the default display mode. This
selects which type of messages the TD device displays after powering up or after a
prolonged period of no key presses by the user.
● Size of the alarms: Select 1 line or 2 lines (TD 100C, TD200 and TD400C), or 4 lines
(TD400C only).
For Chinese characters, select either one row or two rows of text.

up to 40 alarms. The priority for the alarms is determined sequentially, from the first alarm
(highest priority) to the last (lowest priority).
Entering the Text for an Alarm
Clicking Next displays the Alarms dialog shown in the figure below. You can select a
symbolic name for the alarm. The user program uses the symbolic name to enable (and
display) the alarm. Click the New Alarm button to create the alarm message. Your alarm
message can contain the following elements:
● Text: Enter your text in the green area that represents the text display area of the TD
device
● Icons (optional, TD 200C and TD400C): Click the icons in the toolbar to insert the icon
into the text message

Embedding a Variable into the Text of an Alarm
You can embed a variable data field into the text of the alarm. To embed a variable, move
the cursor to the location for the variable in your text and click the Insert PLC Data button. As
shown in the figure below you enter the following information:
Tip
For the TD 200, TD 200C, and the TD400C, you can embed up to 6 variables per alarm. For
the TD 100C, you can embed up to 1 variable per line (1 for one-line alarms, and 2 for two-
line alarms).
● Data address:
– VB: Numeric String, Text String
– VW: Signed, Unsigned
– VD: Real, Signed, Unsigned
● Data Format: Signed, Unsigned, Real, Numeric String, or Text String
● Digits to the right of the decimal: Up to 7
– The TD device rounds a real number to the specified decimal place. For example, if
the real number value is 123.456 and you select 2 digits to the right of the decimal, the
TD 200 displays this value as: 123.46.
Figure 4-28 Inserting a Variable into the Text of an Alarm
Tip
Refer to the SIMATIC S7-200 Programmable Controller System Manual for information
about data types or for the memory addresses supported by the S7-200 CPU.
You can also allow the operator to modify the data stored at this memory location in the S7-
200 CPU.
● You can require the operator enter the TD password before editing the variable. (You
must have enabled password-protection for the TD device.)
● You can configure the cursor to jump to the variable field.
● You can define a symbolic name for the variable. You use the symbolic name to access
this data with your user program.
Clicking OK inserts the variable into the text of the alarm. The Text Display wizard inserts a
block of 4 characters to show the presence of the variable. The value to be displayed for the
variable is right-justified at that location (anchored to the right-most character).

4.5 Configuring the Alarms
Text Display (TD) User Manual
94 System Manual, 08/2008, A5E00765548-03
Data values are always right-justified to the right-most character of an embedded variable.
As a data value grows in magnitude, it utilizes more spaces to the left of the anchor point
and can overwrite the text characters. Always provide sufficient space between the end of
your text and the anchor point to allow for the expected range of the data value.
Tip
The actual number of characters used to display a value varies with the size of the value. To
help calculate the number of characters required for displaying the value of the variable, see
the examples listed in Table 4-2.
The TD device displays all values as decimal numbers. Positive signed values are displayed
without a sign, and negative signed values are displayed with a leading minus sign.
Unsigned values are displayed without a sign. A leading zero is used for all fractional
numbers (for example, 0.5). Real numbers are displayed with the number of decimal places
you specify. The value is rounded to the specified decimal place.
For more information about embedding string variables in an alarm, see page 53.

length is always 20 for a TD 200 or TD 200C. The line length is either 12 or 16 characters for a
TD 100C. The line length for the TD400C depends on the font you selected. If you selected a small
font, you have 24 ASCII characters or 12 Chinese characters per line. If you selected a large font,
you have 16 ASCII characters or 8 Chinese characters per line.

Configuring the Language Sets for the TD Device (TD 200, TD 200C, TD400C)
The Text Display wizard allows you to configure multiple language sets for your TD device,
including not only the system prompts or messages, but also for the user alarms, user
menus, and screens. The Text Display wizard copies the user alarms and user screens that
you have configured into the language set. You must manually enter the translated text for
each alarm, menu, or screen.
For each language set, you select the following information:
● Language for the system prompts
● Character set
● Identifier
You also select which of the language sets is the primary language for the TD device.

Figure 4-29 Configuring the Languages for the TD Device
Tip
When you create multiple language sets, the Text Display wizard copies the user alarms,
menus, and screens from the primary language set to the other language set. You then edit
the alarms, menus, and screens to translate the text displayed for the new language set.
If you need to modify the screens or messages (such as to add a new variable or to add a
new alarm), you must edit the primary language. The Text Display wizard copies these
changes to the other language sets.
The Text Display wizard only allows you to change the text in the other language sets.
After you have configured the alarms and screens for one language set, you can add a new
language set:
1. Click the icon to start configuring the language sets for the TD device.
2. Add a new language by selecting New Language Set.
3. Select an existing language set to be the source for the new language set.

Notes for Using the Simplified Chinese Character Set
Tip
The Simplified Chinese character set requires a Chinese version of Windows or a Chinese
emulator to properly display Chinese characters in the Text Display wizard. You must start
the Chinese emulator before you start the STEP 7-Micro/WIN software.
On the TD 200C, and the TD 200, you can display up to 20 single-byte characters per line of
your message. Because Simplified Chinese uses double-byte characters, you can display up
to 10 double-byte characters per line for a message in Chinese.
On the TD 100C, you can display up to 16 single-byte characters per line of your message.
Because Simplified Chinese uses double-byte characters, you can display up to 8 double-
byte characters per line for a message in Chinese.
On the TD400C using a small font, you can display up to 24 single-byte characters per line
of your message. Because Simplified Chinese uses double-byte characters, you can display
up to 12 double-byte characters per line for a message in Chinese. If you selected a large
font, you can display up to 16 single-byte characters or 12 Chinese characters per line.
The standard ASCII characters, such as numbers, punctuation, and upper and lowercase
alphabet characters, are available when using the Simplified Chinese character set.
Depending on your keyboard and/ or emulator, some of these standard characters may be
formatted as single-byte characters instead of the double-byte characters like the Simplified
Chinese characters. Standard ASCII characters and Chinese characters can be mixed on
the TD display.
The Text Display wizard displays 8, 10 or 12 double-byte character places for the text of a
screen or alarm. You can fit any of the following combinations into a character position:
● 1 double-byte character
● 2 single-byte characters (standard ASCII)
● 1 single-byte character and 1 single-byte blank

Text Display (TD) User Manual
98 System Manual, 08/2008, A5E00765548-03
You cannot fit one single-byte character plus one double-byte character in a character
position.
The TD 100C does not support the entire Simplified Chinese character set, but does support
the most commonly used characters. Characters that are not supported by the TD 100C are
displayed as a square.
See the Simplified Chinese Characters Set on the STEP 7-Micro/WIN documentation CD for
a list of characters supported by the TD 100C.
4.7 Assigning the V Memory Address for the Parameter Block
Assigning the V Memory Address for the Parameter Block
The Text Display wizard creates the parameter block that you download to the S7-200 CPU
with your user program. The parameter block includes the configuration data for the TD
device and any screens and alarms that you created.
The Text Display wizard calculates the amount of memory required for the parameter block
and suggests a starting address in V memory.
The default location for the parameter block is VB0.

4.8 Finishing the Configuration for the TD Device
Finishing the Configuration for the TD Device
After you complete the configuration for your TD device, the Text Display wizard displays a
summary dialog. (See the figure below.)
If you enter a name for the TD configuration, STEP 7-Micro/WIN creates an entry in the
project tree for the TD configuration.
STEP 7-Micro/WIN also creates the following subroutines:
● TD_CTRL_x (where x is the TD configuration number)
– This subroutine ensures that all updates for the TD device (such as alarms or
changing the language setting) occur immediately.
– Your user program should use SM0.0 to call this subroutine every scan

4.8 Finishing the Configuration for the TD Device
Text Display (TD) User Manual
System Manual, 08/2008, A5E00765548-03 99
● TD_ALM_x (where x is the TD configuration number)
– Your user program uses this subroutine to call the alarm by the symbolic name
(configured by the Text Display wizard). This subroutine requires the S7-200 Symbol
Table.
– Your user program should call TD_ALM_x on every scan when the alarm is present.
Figure 4-33 Summary Dialog
Note
The TD_CTRL_X subroutine will clear the alarm enable bits each time it is called. This
behavior could be problematic if the TD configuration contains alarms that require
acknowledgement. The TD_CTRL_x subroutine may disable these alarms before they
can be displayed and acknowledged on the TD device. Your program logic must
ensure that any TD_ALM_x alarm subroutine that requires acknowledgement remains
enabled until the TD device writes the alarm acknowledgement bit in the CPU.

Operating Your TD Device
Included in this chapter is information about routine operator tasks, such as entering and
releasing the password, editing variables embedded in a message or screen, and checking
the status information of the S7-200 CPU. This chapter also describes the less-routine
diagnostic functions provided by the TD device for troubleshooting problems in the S7-200
CPU, such as forcing I/O or changing the operating mode
5.2 Using the Text Display Device to Access Screens and Alarms
Using the TD Device to Access Screens and Alarms
The TD devices allow you to structure information as either screens or bit-enabled alarm
messages. You use the buttons of the keypad of the TD device to navigate through the
screens and menus:
● TD 200: Uses the standard TD keypad.
● TD 100C, TD 200C, and TD400C: Allow you to change the configuration and use your
own custom-designed keypad. (If there is no custom configuration, the TD 100C,TD 200C
and TD400C defaults to the standard TD keypad configuration.)
Tip
For more information about configuring the functionality of the buttons on the keypad:
● Chapter 4 provides information about configuring the buttons for the TD devices. The TD
configuration is downloaded to the S7-200 CPU with your user program.
● Chapter 3 provides information about creating a custom keypad layout for the TD device,
and assigning specific functionality for each button. (You then integrate the custom
keypad with the screens and alarm messages as described in Chapter 4.)

● Pressing ENTER selects the highlighted item.
● Pressing ESC returns to the previous menu or screen.
Display Backlight on the TD400C
The TD400C allows you to set the amount of time that the display backlight is on. This allows
you to extend the life of theTD400C by turning off the backlight when the display is not
needed.
You can configure the TD400C display backlight on time:
● From 1 to 59 minutes in 1 minute increments
● Always on
● 1, 2, 4, or 8 hours
● Default on time (10 minutes)
The backlight will turn on when:
● The TD400C is powered on
● The S7-200 CPU forces a reset of the TD400C with the TD_Reset bit in the TD parameter
block.
● You press a key. The time is extended each time a key is pressed.
● A new alarm is read from the S7-200 CPU
When the display backlight is turned on, the backlight is on for the time that you configured in
the TD Setup menu.
If the backlight is currently off and you press a key, the first keypress will turn on the
backlight, but will not execute the key function. You must press the key a second time to
execute the key function. There will be no audio or visual feedback for the first keypress that
turns on the backlight. This lets you know that the key did not execute the key function and
you must press the key again.
If your TD400C has an alarm that requires acknowledgement (an alarm that flashes or
blinks), and that alarm is enabled, the display backlight will be on until you acknowledge the
alarm.

Displaying Information on the TD Device
The TD device provides both screens (user-defined menus with associated screens of
information) and bit-enabled alarm messages:
● Menu: A menu is a list of items that select a grouping of related screens. The TD 200,
TD 200C and the TD400C have 8 menus available; the TD 100C has 4 menus available
● Screen or alarm:
– A screen or alarm for the TD 200 and TD 200C displays up to two lines of text that
provide information for the operator. Each line can be up to 20 characters of text and
data. A screen contains up to 40 characters of text and data. An alarm can be either 1
or 2 lines.
– A screen or alarm for the TD400C displays up to four lines of text that provide
information for the operator. Each line can be up to 24 characters of text and data. A
screen contains up to 96 characters of text and data. An alarm can be either 1, 2, or 4
lines.
– A screen or alarm for the TD 100C displays up to four lines of text that provide
information for the operator. (Each line can contain either 12 or 16 characters of text
and data. A screen contains 48 or 64 characters of text and data. An alarm can be
either 1 or 2 lines.)
The textual message of the screen or alarm can convey information for the operator
and can also allow the operator to interact with the S7-200 CPU by changing the
embedded value of a variable (such as a set point or limit).
You can configure the TD device to display screens (which are initiated by operator action)
and bit-enabled alarms (which are generated by the S7-200 CPU). You can also configure
the TD 200 and TD 200C, and TD400C device to display an icon to alert the operator of
some event or action required. (Refer to Chapter 4 for information about configuring the TD
device.)
Tip
Pressing ESC returns you to the previous menu. If there is no activity for 20 seconds (no
button pressed), the TD device returns to the default display mode.
The operator uses the buttons on the keypad to navigate through the menu or a list of text.
Figure 5-2 shows the buttons that an operator could use to navigate from a user menu to the
screens associated with that item in the menu. Figure 5-3 shows how to navigate through the
alarms. The TD 200, TD 200C, and the TD400C have eight menus available, and the
TD 100C has four menus available.

A screen or alarm message can contain an embedded variable field that allows an operator
to respond by changing the value of the variable. The operator uses the keypad to edit
variables:
● Selecting the Screen: The operator uses the UP or DOWN arrows to display the screen
that contains the variable to be edited. (From a menu, the operator presses ENTER to
access the group of screens.)
● Navigating to the variable: The operator presses ENTER to navigate to the first editable
variable.
● Changing the value of the variable: Pressing the UP arrow increments (increases) the
value, and pressing the DOWN arrow decrements (decreases) the value. (Pressing and
holding the UP or DOWN arrow accelerates the operation.) Pressing both SHIFT+ENTER
resets the variable to 0. Pressing ESC aborts the edit.
● Press LEFT or RIGHT to move the cursor position within the variable. The TD 200 uses
SHIFT+UP to move left and SHIFT+DOWN to move right.
● Updating the data in the S7-200 CPU: Pressing ENTER writes the updated value for the
variable to the S7-200 CPU and moves the cursor to the next editable variable on the
screen.
For more information about editing variables, see the section Editing a Variable that is
Embedded in an Alarm or a Screen in this chapter.
5.3 Accessing the Menus and Screens
Accessing the Menus and Screens
When you configured the TD device (as described in Chapter 4), you created the screens
and alarms for the TD device. If you configured both alarms and screens, you also
designated which type of message (screens or the alarms) would be the default display
mode for the TD device. After power-up or after a period of inactivity, the TD device returns
to the default display mode.
In addition to the screens and alarms that you configured, the TD device provides standard
functions that the operator can access from system-level and pre-defined menus. From the
default display mode, the operator uses ESC to access the menu hierarchy. The operator
then presses ENTER to select the menu item for accessing the other menus or functions.
Figure 5-5 and Figure 5-6 show the hierarchy of menus for these functions for the TD
devices. (The menus show all of the functions that are available on the TD device. For some
of the functions to be listed on the menu, you must have enabled the function during
configuration. See Chapter 4.)

5.4 Entering and Releasing a Password
Entering and Releasing a Password
You use the Text Display wizard of STEP 7-Micro/WIN to configure the password for the TD
device. Refer to Chapter 4 for information about configuring the TD device. To ensure that
an unauthorized user does not have access to the TD device during an interval for the
automatic time-out, you can use the Release Password feature.
Certain operations (such as forcing I/O or making a memory cartridge) may also require that
the operator enter the 8-character CPU password for the S7-200 CPU. (You must have
enabled the S7-200 CPU for password-protection in order for the TD device to prompt the
operator for the CPU password.)
Entering the Password
If configured for a password, the TD device prompts the operator to enter the 4-digit
password before allowing the operator to access screens or menus. If the password uses
fewer than 4 digits, the operator must press ENTER for the unused (remaining) characters.
Use the UP or DOWN arrow to select each digit of the password, pressing ENTER to move
to the next digit. You can also use the RIGHT and LEFT arrows to move within the
password.
The TD device provides a time-out feature which automatically restores password protection
after a period of inactivity. If no buttons have been pressed after 2 minutes, the TD device
then requires a password again before allowing an operator to access menus or to edit
variables.
Releasing the Password
In order to provide additional security for your application, the TD device provides a Release
Password command that immediately restores the password-protection. The TD device then
requires that the operator enter the password before allowing access. The Release
Password command prohibits another person from using the TD device without first entering
a password (for example, before a password entered by an operator times out).
You access the Release Password command from the main menu, as shown in figure below.
The Release Password is not applicable for the CPU password: The TD device releases the
CPU password as soon as the operator exits the function that required the password.
For example: If the operator entered the CPU password in order to force an I/O point in the
S7-200 CPU, the TD device releases the CPU password as soon as the operator exits the
Force menu.
The Release Password command is available only if you defined a 4-digit password when
you configured the TD device.

As described in Chapter 4, you can configure screens and alarms for the TD device. If you
configure both alarms and screens, you also designate which set of messages (screens or
alarms) are the default display mode for the TD device. The default configuration selects the
screens to be the default display.
After power-up or after a period of inactivity (one minute), the TD device returns to the
default display mode. As shown in the figures below, the operator can switch between the
default display mode and the secondary display mode.
Tip
For the TD 100C, TD 200C, and the TD400C: If you do not configure buttons for ESC or
ENTER, you cannot access the main menu.

Displaying the Alarms
If you created both screens and alarms when you configured the TD device, the main menu
of the TD device includes a command that allows you to access the secondary (non-default)
display. The TD device always returns to the default display mode after a period of inactivity.
As shown in the TD 200C example in the figure below, the main menu provides a Display
Alarms command for the default TD configuration. If you configured alarms as the default
display, the main menu lists a User Menu entry.
After displaying the alarms, you use the UP and DOWN arrows to scroll through the
sequential list of alarms.

Figure 5-9 Displaying the Alarms
Tip
The TD 100C, TD 200C, and the TD400C allow you to configure a button specifically for
displaying alarms when you are creating your custom keypad.
The TD device displays the highest priority alarm. The TD device displays an up or down
arrow with the alarm to alert the operator that other alarms have been enabled. (The up
arrow shows that higher-priority alarms have been enabled, and the down arrow shows that
lower-priority alarms have been enabled.)
After reading a new alarm from the S7-200 CPU, the TD device sorts the alarms again to
display the highest priority alarms at the top of the list. The TD device determines the priority
based on the sequence of the alarms in the parameter block:
● The first alarm that you created has the highest priority.
● The second alarm that you created has the second-highest priority.
● The last alarm that you created has the lowest priority.
Tip
You can scroll up and down through the list of enabled alarms. However, the TD device
returns to the highest-priority alarm after a period of inactivity: If you have not pressed a
button for 10 seconds while the TD device has displayed the current alarm, then the TD
device automatically returns to the highest-priority alarm.
Acknowledging an Alarm
If an alarm requires acknowledgement, the TD device does not remove that alarm until you
acknowledge the alarm:
1. Use the UP or DOWN arrow to select the alarm.
2. Press ENTER to acknowledge the alarm.
Types of Alarms
The Text Display wizard allows you to determine the type interaction required by the
operator for an alarm. If the user screens are set as the default display mode for the TD
device and an alarm is enabled, an alarm indicator will begin to flash on the TD display. The
indicator is large if there is an alarm enabled that requires acknowledgement. The indicator
will be small if the alarms do not require acknowledgement. The user can switch to the alarm
display to view the alarms.
The alarm display will show one or more alarms in priority order. An UP or DOWN arrow in
the right-most character position indicates more alarms are active, but not visible on the
display. The operator can press either the UP or the DOWN arrow key to scroll through the
other enabled alarms.

5.5 Viewing the Screens and the Alarms
Text Display (TD) User Manual
114 System Manual, 08/2008, A5E00765548-03
The operator can edit or accept variable values by pressing the ENTER key. The TD device
will write the updated variable value to the CPU and set the edit notification bit for that
variable when the operator presses the ENTER key. The TD device then moves the cursor
to the next editable variable. Pressing ENTER for the last editable variable of an alarm writes
this last value to the S7-200 CPU and the TD device then resets the alarm enable bit. For
more information on editing variables, see Editing a Variable that is Embedded in an Alarm
or a Screen in Chapter 5.
Every alarm falls into one of four possible alarm acknowledgement and editing types. This
section explains specifically how each alarm type is handled by the TD device. The four
alarm types follow:
● No acknowledgement required. No edits allowed
● Acknowledgement required. No edits allowed
● No acknowledgement required. Edits allowed
● Acknowledgement required. Edits allowed
No Acknowledgement Required, No Edits Allowed
In this combination of no acknowledgement required and no edits allowed, the TD device
simply displays the alarm. The ENTER key has no function since there are no editable
variables within the alarm. The alarm may contain variables that are updated at the update
rate of the TD device. This type of alarm is replaced on the display if a higher priority alarm is
enabled by the S7-200 CPU. The operator can either press the UP or the DOWN arrow key
to scroll to other alarms or press ESC to return to the menus.
The TD device does not clear the corresponding alarm-enable bit in the S7-200 CPU.
Acknowledgement Required, No Edits Allowed
In this combination of acknowledgement required and no edits allowed, the TD device
displays the alarm and makes the entire alarm flash (blink) until the operator presses ENTER
to acknowledge the alarm. Variable values are updated from the S7-200 CPU at the normal
update rate while the alarm is flashing.
When the operator presses ENTER, the TD device:
● Sets the acknowledgement-notification bit for this alarm.
● Clears the alarm-enable bit for this alarm. This causes the alarm to be removed from the
display on the next update cycle.
Another alarm cannot replace the one flashing until the operator acknowledges the flashing
alarm. This is also true even if a higher priority alarm is enabled in the S7-200 CPU. If the TD
device is configured for single line alarms and the CPU enables a higher priority alarm, the
flashing alarm shifts down to the next line of the display. The operator cannot press the UP
or the DOWN key to scroll through other enabled alarms until the current alarm is
acknowledged.
No Acknowledgement Required, Edits Allowed
In this combination of no acknowledgement required and edits allowed, the TD device
displays a alarm and then waits for the operator to edit a value in the alarm. All of the
variables within the alarm are updated at the update rate. Since the alarm does not require
acknowledgement, this type of alarm is removed from the TD device display if a higher
priority alarm is enabled in the S7-200 CPU.

5.5 Viewing the Screens and the Alarms
Text Display (TD) User Manual
System Manual, 08/2008, A5E00765548-03 115
Acknowledgement Required, Edits Allowed
In this combination of acknowledgement required and edits allowed, the TD device displays
the alarm, causes the entire alarm to flash (blink), and then waits until the operator
acknowledges the alarm and edits or accepts the values in the alarm. This type of alarm
requires that the operator edits or accepts the values displayed in the alarm. If the operator
aborts the edit by pressing the ESC key before editing all the values in the alarm, the alarm
flashes to indicate that edits are still required.
When the alarm is enabled in the S7-200 CPU, the TD device notes this and, if there is
space available on the display, reads the alarm from the CPU. The TD device then displays
the alarm and causes the entire alarm to flash to notify the operator that the alarm is present
and must be acknowledged.
Clearing an Alarm
● If an alarm required acknowledgement, the TD device will clear the alarm enable at the
same time that the Alarm Acknowledgement bit is set in the CPU.
● If an alarm contains editable variables, the TD device will clear the alarm enable bit when
all of the edits are completed and the last editable variable in the messages is written to
the CPU.
● The PLC program logic may clear the alarm enable bit at any time. This will remove the
alarm message from the TD display. An alarm message will not be removed from the
display if the user is editing a variable in the message or if the message has not yet been
acknowledged.
● If the message does not require acknowledgement and/or does not contain editable
variables, then the CPU program logic MUST clear the alarm enable bit.
Editing a Variable that is Embedded in an Alarm or a Screen
If you configured a screen or an alarm to include a variable, you can enter a new value for
the variable:
● Use ENTER to move the cursor to the variable. The TD device will write the updated
variable value to the CPU and set the edit notification bit for that variable when the
operator presses the ENTER key, completing the edit of the variable.
● Use the UP or DOWN arrows to change the value of the variable.
● Use the following buttons to move the cursor to different characters within the variable:
– TD 100C, TD 200C, and TD400C: LEFT and RIGHT arrows
– TD 200: SHIFT+UP arrow and SHIFT+DOWN arrow
● ESC rereads the value of the variable from the S7-200 CPU and redisplays the value.
● ENTER writes the new value to the S7-200 CPU. (If the alarm contains other variables,
the cursor moves to the next variable.) The TD device will write the updated variable
value to the CPU and set the edit notification bit for that variable when the operator
presses the ENTER key, completing the edit of the variable.
If the variable was configured as a numeric string, the cursor skips over any non-numeric
characters in the message. See Chapter 4. After you have edited all of the variables in an
alarm, the TD device resets the alarm bit in the S7-200 CPU.

Notice
Due to restrictions in the format used to store real (floating-point) numbers in both the S7-
200 CPU and the TD device, the accuracy of the number is limited to six significant digits.
Editing a real number with more than six digits may not change the value of the variable, or
may cause other digits within the number to change:
● Changing the least significant (right-most) digit of a real-number variable with more than
six digits may have no effect. For example, if you try to change the "9" in "1234.56789",
the value of the variable does not change.
● Changing the most significant (left-most) digit of a real-number variable with more than
six digits may cause other (less significant) digits in the variable to change.

When an alarm is enabled and the TD default
display mode is set to the alarm mode, the alarm
message is placed on the TD display. If there are
multiple alarms enabled, the highest priority
alarm is displayed.
If an alarm requires user acknowledgment, the
message will flash (blink) until it is acknowledged
by the user. The alarm MUST be acknowledged
before other alarms can be viewed. An alarm that
requires acknowledgement will not be replaced
on the display by higher priority alarms until the
alarm is acknowledged.
If the alarm contains editable variables the user
can edit or accept the values (by pressing the
ENTER key). If the edits are not completed, and
the alarm message required acknowledgement,
the message will again begin to flash.
If the user screens are set as the default display
mode for the TD device and an alarm is enabled,
an alarm indicator will begin to flash on the TD
display. The indicator is large if there is an alarm
enabled that requires acknowledgement. The
indicator will be small if the alarms do not require
acknowledgement. The user can switch to the
alarm display to view the alarms. The alarms will
be presented to the user in priority order.
There are different ways to
clear the alarm enable bit:
If an alarm required
acknowledgement, the TD
device will clear the alarm
enable at the same time that
the 'Alarm
Acknowledgement' bit is set
in the CPU.
If an alarm contains editable
variables, the TD device will
clear the alarm enable bit
when all of the edits are
completed and the last
editable variable in the
messages is written to the
CPU.
The PLC program logic may
clear the alarm enable bit at
any time. This will remove
the alarm message from the
TD display. An alarm
message will not be removed
from the display if the user is
editing a variable in the
message or if the message
has not yet been
acknowledged.
If the message does not
require acknowledgement
and/or does not contain
editable variables, then the
CPU program logic MUST
clear the alarm enable bit.

If the user screen
contains multiple
editable variables,
each variable has
a unique edit
notification bit.
The TD device will write the updated variable
value to the CPU and set the edit notification bit
for that variable when the operator presses the
ENTER key, completing the edit of the variable.
The user program can
monitor the edit notification
bit to recognize when an
editable value has been
changed by the operator.
The user program can then
take some action based on
the new value for the
variable.
The user program must clear
the edit notification bit so that
subsequent edits can be
recognized.

Setting Time and Date in the S7-200 CPU
You can use the TD device to change the time-of-day settings in the S7-200 CPU. This
allows an operator to easily adjust for time changes.
The TD device does not maintain time and date settings. In order to display the time and
date values, the TD device reads the current time and date from the S7-200 CPU and
displays these values. The operator can then use this screen to edit these values and then
write the new time and date settings back to the S7-200 CPU.
Tip
The TD device does not validate the time, date or day of the week values that you enter. You
can inadvertently write an incorrect date or day of the week to the S7-200 CPU.
To allow an operator to change the time and date settings in the S7-200 CPU:
● You must have enabled (selected) the time-of-day (TOD) option when you configured the
TD device with the Text Display wizard. Refer to Chapter 4.
● The S7-200 CPU must support the TOD clock
Tip
If you configured a password for the TD device, the operator must enter the password before
being allowed to set the time and date.

● Setting the baud rate for the TD device: choose the baud rate for the TD device. You can
choose either 9.6 kbaud (9600 baud), 19.2 kbaud, or 187.5 kbaud.
Use the UP or DOWN arrow to select the baud rate. The baud rate must match the baud
rate of the S7-200 CPU and any other device on the same network.
● Setting the Highest Station: Changes the highest station address for the TD device. This
setting tells the TD device which network addresses to check when looking for other
network master devices. The default highest station address is 31. This means that the
TD device checks addresses 0 through 31 when looking for other network masters. This
setting should only be changed when there are more than 32 master devices on the
network.
Use the UP and DOWN arrows to select the highest address on the network
(default = 31).
● Setting the Gap Factor: Changes the Gap Factor for the TD device. This setting tells the
TD device how often to check for other network master devices. The default setting of 10
causes the TD device to check once every 10 messages. A setting of 1 would cause the
TD device to check for other masters after every message.
Use the UP and DOWN arrows to select the gap factor between stations (default = 10).
● Setting the contrast:
– TD 100C, TD 200, and TD 200C: You can optimize the display for different viewing
angles and lighting conditions by adjusting the contrast of the screen on the TD
device. The default contrast value is 40, with values ranging from 25 (lighter) to 55
(darker).
Use the UP and DOWN arrows to select the contrast setting for the display area of the
TD device (default setting = 40).

● Selecting the keypad buzzer: The TD400C has a keypad buzzer setting (On or Off) to
provide audio feedback when a key is pressed. The default is set to On.
● Setting the display backlight time: The TD400C allows you to set the time that the display
backlight is on allowing you to extend the life of the TD400C display.
– The backlight on time is configurable from 1 to 60 minutes in one minute increments
– You can configure the backlight to be on all the time
– The default backlight on time is 10 minutes
Tip
At 9600 baud or 19.2 kbaud, the highest station address may need to be increased, even
though the network does not contain more than 32 masters. Increasing the highest station
address allows more time for the masters to transmit messages.
Viewing the TD Messages Stored in the S7-200 CPU (TD 200, TD 200C, and TD400C only)

A.9 Simplified Chinese Character Set
Simplified Chinese Character Set
The TD devices support the Simplified Chinese character set (GB2312-80) for the People's
Republic of China. The TD devices use Microsoft Windows encoding for this character set.
The Windows encoding allows the TD devices to display the same characters as shown in
the STEP 7-Micro/WIN Text Display wizard when you are using a Chinese emulator or a
Chinese version of Microsoft Windows.
Chinese characters are represented in STEP 7-Micro/WIN by a pair of numbers which
represent the encoding of the character in the GB2312-80 specification. The TD devices also
use a pair of numbers to represent the Chinese character.
Notes for Using the Simplified Chinese Character Set
Tip
The Simplified Chinese character set requires a Chinese version of Windows or a Chinese
emulator to properly display Chinese characters in the Text Display wizard. You must start
the Chinese emulator before you start the STEP 7-Micro/WIN software.
On the TD 200C and the TD 200, you can display up to 20 single-byte characters per line of
your message. Because Simplified Chinese uses double-byte characters, you can display up
to 10 double-byte characters per line for a message in Chinese.
On the TD 100C, you can display up to 16 single-byte characters per line of your message.
Because Simplified Chinese uses double-byte characters, you can display up to 8 double-
byte characters per line for a message in Chinese.
On the TD400C using a small font, you can display up to 24 single-byte characters per line
of your message. Because Simplified Chinese uses double-byte characters, you can display
up to 12 double-byte characters per line for a message in Chinese. If you selected a large
font, you can display up to 16 single-byte characters or 8 Chinese characters.
The standard ASCII characters, such as numbers, punctuation, and upper and lowercase
alphabet characters, are available when using the Simplified Chinese character set (shown
below). Depending on your keyboard and/ or emulator, some of these standard characters
may be formatted as single-byte characters instead of the double-byte characters like the
Simplified Chinese characters. Standard ASCII characters and Chinese characters can be
mixed on the TD display.
The Text Display wizard displays 8 , 10, or 12 double-byte character places for the text of a
screen or alarm. You can fit any of the following combinations into a character position:
● 1 double-byte character
● 2 single-byte characters (standard ASCII)
● 1 single-byte character and 1 single-byte blank
You cannot fit one single-byte character plus one double-byte character in a character
position.

Figure B-1 shows a typical network with two TD 200s and two S7-200 CPUs. Each TD 200
communicates to one of the CPUs. The addresses of each device are noted below the
device in the figure. In this example:
● TD 200 Number 1 is configured to communicate to the S7-200 CPU at address 2 (CPU 1)
● TD 200 Number 2 is configured to communicate to the S7-200 CPU at address 3 (CPU 2)
Tip
You can connect multiple TD devices to a single S7-200 CPU. You can store separate
parameter blocks for each TD device in different V memory locations in the CPU.
If you do not store separate parameter blocks for each TD device that is connected to the
CPU, any of these TD devices can acknowledge the same messages and use function keys
to initiate operations in the CPU.

156 System Manual, 08/2008, A5E00765548-03
Tip
The display time slows as more TD devices are added to the network.
Network connectors are available from Siemens. Using these connectors allows you to
isolate the CPUs from one another (the 24 VDC), but still allows you to power the TD device
from the CPU. See the SIMATIC S7-200 Programmable Controller System Manual for more
information about using network connectors.
B.3 Determining the Distances, Transmission Rate, and Cable
Determining the Distances, Transmission Rate, and Cable
As shown in Table B-1, the maximum length of a network segment is determined by two
factors: isolation (using an RS-485 repeater) and baud rate.
Isolation is required when you connect devices at different ground potentials. Different
ground potentials can exist when grounds are physically separated by a long distance. Even
over short distances, load currents of heavy machinery can cause a difference in ground
potential.
Table B- 1 Maximum Length for a Network Cable
Baud Rate Non-Isolated CPU Port1 CPU Port with Repeater or EM 277
9.6 kbaud to 187.5 kbaud 50 m 1,000 m
1 The maximum distance allowed without using an isolator or repeater is 50 m. You
measure this distance from the first node to the last node in the segment,
Using Repeaters on the Network
An RS-485 repeater provides bias and termination for the network segment. You can use a
repeater for the following purposes:
● To increase the length of a network: Adding a repeater to your network allows you to
extend the network another 50 m. If you connect two repeaters with no other nodes in
between (as shown in Figure B-2), you can extend the network to the maximum cable
length for the baud rate. You can use up to 9 repeaters in series on a network, but the
total length of the network must not exceed 9600 m.
● To add devices to a network: Each segment can have a maximum of 32 devices
connected up to 50 m at 9600 baud. Using a repeater allows you to add another segment
(32 devices) to the network.
● To electrically isolate different network segments: Isolating the network improves the
quality of the transmission by separating the network segments which might be at
different ground potentials.
A repeater on your network counts as one of the nodes on a segment, even though it is not
assigned a network address.

Selecting the Network Cable
S7-200 networks use the RS-485 standard on twisted pair cables. Table B-2 lists the
specifications for the network cable. You can connect up to 32 devices on a network
segment.

Nominal impedance Approximately 135 Ω to 160 Ω (frequency =3 MHz to 20 MHz)
Attenuation 0.9 dB/100 m (frequency=200 kHz)
Cross-sectional core area 0.3 mm2 to 0.5 mm2
Cable diameter 8 mm ±0.5 mm
B.5 Biasing and Terminating the Network Cable
Biasing and Terminating the Network Cable
Siemens provides two types of network connectors that you can use to easily connect
multiple devices to a network: a standard network connector and a connector that includes a
programming port (which allows you to connect a programming station or an HMI device to
the network without disturbing any existing network connections). The programming port
connector passes all signals (including the power pins) from the S7-200 through to the
programming port, which is especially useful for connecting devices that draw power from
the S7-200 (such as a TD 200).
Both connectors have two sets of terminal screws to allow you to attach the incoming and
outgoing network cables. Both connectors also have switches to bias and terminate the
network selectively. Figure B-3 shows typical biasing and termination for the cable
connectors.

B.6 Building a TD/CPU Cable
Building a TD/CPU Cable
The TD/CPU cable is used for connecting a display device to an S7-200 CPU. If you do not
have a TD/CPU cable, refer to Figures B-4 and B-5 to create your own cable.
Making a Cable That Supplies Power to the TD Device
CAUTION
Connecting the 24 VDC power output (pin 7 of communication port) of multiple S7-200
CPUs may cause erratic operation of the I/O, which could potentially cause personal injury
and/or property damage.
The 24 VDC power supply is also the sensor supply for the I/O. Interconnecting the output
power supplies of multiple CPUs could possibly overload the sensor supply, which could
cause the I/O to operate incorrectly.
When networking S7-200 CPUs, connect only the communication lines (pins 3, 5, and 8).
You must not connect the power output (pin 7).
Tip
The TD 100C must use the TD/CPU cable shown in Figure B-4.

B.7 CPU Grounding and Circuit Reference Point Guidelines for Using
Isolated Circuits
CPU Grounding and Circuit reference Point Guidelines for Using Isolated Circuits
The following items are CPU grounding and circuit guidelines for using isolated circuits:
● You should identify the reference point (0 voltage reference) for each circuit in the
installation, and the points at which circuits with possibly different references can connect
together. Such connections can result in unwanted current flows that can cause logic
errors or can damage circuits. A common cause of different reference potentials is
grounds that are physically separated by long distances. When devices with widely
separated grounds are connected with a communication or sensor cable, unexpected
currents can flow through the circuit created by the cable and the ground. Even over short
distances, load currents of heavy machinery can cause differences in ground potential or
can directly induce unwanted currents by electromagnetic induction. Power supplies that
are improperly referenced with respect to each other can cause damaging currents to
flow between their associated circuits.
● When you connect CPUs with different ground potentials to the same PPI network, you
should use an isolated RS-485 repeater.
● S7-200 products include isolation boundaries at certain points to help prevent unwanted
current flows in your installation. When you plan your installation, you should consider
where these isolation boundaries are provided, and where they are not provided. You
should also consider the isolation boundaries in associated power supplies and other
equipment, and where all associated power supplies have their reference points.
● You should choose your ground reference points and use the isolation boundaries
provided to interrupt unneeded circuit loops that could allow unwanted currents to flow.
Remember to consider temporary connections which may introduce a new circuit
reference, such as the connection of a programming device to the CPU.
● When locating grounds, you must also consider safety grounding requirements and the
proper operation of protective interrupting devices.
● In most installations, you will have the best noise immunity if you connect the CPU sensor
supply M terminal to ground.
The following descriptions are an introduction to general isolation characteristics of the S7-
200 family, but some features may be different on specific products. Consult your product
specifications in the appropriate manual for information about which circuits include isolation
boundaries and the ratings of the boundaries. Isolation boundaries rated less than 1,500
VAC are designed as functional isolation only, and should not be depended on as safety
boundaries.
● Logic circuit reference is the same as DC sensor supply M.
● Logic circuit reference is the same as the input power supply M on a CPU with DC power
supply.
● CPU communication ports have the same reference as logic circuit.
● Analog inputs and outputs are not isolated from logic circuit. Analog inputs are full
differential to provide low voltage common mode rejection.
● Logic circuit is isolated from ground to 500 VAC.
