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.
Tip
The TD devices provide additional functionality, such as the hierarchical user-defined
menus. The TD 200C and the TD 200 are fully compatible with projects that were created
with earlier versions of the TD 200 (prior to TD 200 V3.0, which supported only the bit-
enabled messages from the S7-200 CPU).
You can use the TD 200C or the TD 200 device with an existing TD configuration without
having to modify the control program in the S7-200 CPU.
The TD 100C and the TD400C devices are not compatible with the TD 200 devices.
1.2 Introducing the S7-200 Text Display (TD) Device
Introducing the S7-200 Text Display (TD) Devices
Your S7-200 TD device is a 2- or 4-line text display device that can be connected to the
S7-200 CPU. The TD device allows you to view, monitor, and change the process variables
pertaining to your application.
The S7-200 product family provides four TD devices:
● TD 100C: The TD 100C has a 4-line text display with 2 font choices. Your display can
have 16 characters per line for a total of 64 characters, or you can use a bold font with 12
characters per line for a total of 48 characters. The faceplate of the TD 100C offers
complete flexibility of the keypad layout and faceplate design.
You can create a custom keypad with up to 14 buttons (keys) of variable size, with
varying shapes, colors, or fonts that can be layered onto any background image.
● TD 200C: The TD 200C has a 2-line text display with 20 characters per line for a total of
40 characters. The faceplate of the TD 200C offers complete flexibility of the keypad
layout and faceplate design.
You can create a custom keypad with up to 20 buttons (keys) of variable size, with
varying shapes, colors, or fonts that can be layered onto any background image.

● TD 200: The faceplate of the TD 200 provides four keys with predefined, set-bit functions
and allows up to eight set-bit functions by using the SHIFT key.
● TD400C: The TD400C can have a 2- or 4-line text display depending on your font and
character choice.The TD400C buttons (keys) are tactile and have fixed positions.
– Your display can have a 4-line display with 12 small Chinese characters per line for a
total of 48 characters, or 24 small ASCII characters per line for a total of 96
characters.
– Your display can have a 2-line display with 8 large Chinese characters per line for a
total of 16 characters, or 16 large ASCII characters per line for a total of 32 characters.
– You can create a custom keypad with up to 15 buttons (keys) of varying colors,
functions, or fonts that can be layered onto any background image.

The TD devices contain the following elements:
● Text display area: The TD 200C, TD 200 and TD400C have a backlit liquid crystal display
(LCD).
– The TD 200C and TD 200 displays have a resolution of 33 x 181 pixels
– The TD400C display has a resolution of 192 x 64 pixels.
– The TD 100C has a liquid crystal display (LCD) with a resolution of 132 x 65 pixels.
There is no backlight on the TD 100C.
● Communication port: 9-pin D-connector
● Power connector
– The TD 200C, TD 200, and TD400C have a connector for using an optional external
power supply (power for the TD device is typically supplied by the S7-200 CPU
through the TD/CPU cable).
– The TD 100C does not have the option of using an external power supply.
STEP 7-Micro/WIN provides tools to help you configure the TD devices. Using the following
tools, you can easily program your S7-200 to display text messages and other data:
● Text Display wizard helps you configure messages for the TD devices.
● Keypad Designer helps you to configure the custom keypad for the TD 100C, the
TD 200C, and the TD400C. The Keypad Designer includes samples and templates in the
following directories:
– Sample bitmaps for buttons and backgrounds:
C:/Program Files/Siemens/TD Keypad Designer/Images
– Sample projects:
C:/Program Files/Siemens/TD Keypad Designer/Samples
– Sample template (for printing multiple copies of the faceplate):
C:/Program Files/Siemens/TD Keypad Designer/Templates
Each TD device functions as a network master when it is connected over a network that
contains one or more S7-200 CPUs. The TD device is also designed to operate with other
masters in a network. Multiple TD devices can be used with one or more S7-200 CPUs
connected to the same network. More than one TD device can connect to the same S7-200
CPU.

1.3 Features of the Text Display (TD) Devices
Features of the Text Display (TD) Devices
You can use your TD device to perform the following tasks:
● Viewing a hierarchy of user menus and screens that allow an operator to interact with the
application or process
You create these user menus and screens with the Text Display wizard of
STEP 7-Micro/WIN
● Displaying alarms (bit-enabled messages) that are generated by the S7-200 CPU
You define these alarms with the Text Display wizard of STEP 7-Micro/WIN
● Modifying designated program variables
The TD device allows you to define a variable as either a text string or a numeric string:

– Numeric string: Only the numeric characters are editable (the cursor skips over all
non-numeric characters)
The TD device allows you to define a variable as a word, double word, or real
● Forcing or unforcing I/O points: You can force individual I/O points in the S7-200 CPU to
be on or off (TD 200C, TD 200, and TD400C only)
● Setting the time and date (if the S7-200 CPU supports a real-time clock)
● Viewing the CPU status (including version information)
The TD 200C and TD400C provide additional functionality for interacting with the S7-200
CPU:
● You can change the operating mode (RUN or STOP) of the S7-200 CPU
● You can load the user program in the S7-200 CPU to a memory cartridge
● You can access and edit the data stored in the memory of the S7-200 CPU

Using the TD Device to Access Screens and Alarms
When you configure the TD device with the Text Display wizard of STEP 7-Micro/WIN, you
create the screens and alarms for the TD device. You use the buttons on the keypad of the
TD device to navigate through the screens and menus. The TD 200 device uses the
standard TD keypad. The standard faceplates for the TD devices are shown in Figure 1-2.
The TD 100C and TD 200C allow you to create your own custom-designed buttons with
specialized functions.

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).
