Preface
Purpose
The
SIMATIC TD 200 Operator Interface User Manual is a combination user and reference
manual that describes the operation of the TD 200 Operator Interface Module with an S7-200
programmable logic controller.
Audience
This manual is designed for engineers, programmers, and maintenance personnel who have
a general knowledge of programmable logic controllers and operator interfaces.
Scope of This Manual
This manual describes the operation of version 1.1 and later of the TD 200. This release
includes new features and other operational enhancements.
Release Notes
Version 1.1 of the TD 200 includes the following new features:
SSupports real (floating-point) numbers
SProvides password protection for editable variables and for the Menu mode of operation
SSupports multiple parameter blocks in a single S7-200 CPU (with a setup menu for
entering the V memory address)
SSupports 19.2 Kbaud communication rate (with a setup menu for changing the baud rate)
SSets a bit in the parameter block every time an arrow key is pressed, thus allowing your
program to have more control of the TD 200
SIncludes an alternative character set for creating bar charts
Other enhancements (such as using any key—not just the ESC key—to cancel the scrolling
of the messages, or using SHIFT-ENTER to set a variable to 0) either improve the
performance of the TD 200 or make it easier to use. For example, you can now use the
SHIFT-UP/DOWN arrow keys to perform a character-by-character edit of a variable that is
embedded in a message.
Version 1.2 of the TD 200 includes the following new features:
SCorrects problems with multi-master networks
SMakes the editors more consistent
For upgrades to version 1.2 of the TD 200, contact your distributor.

Configuring the TD 200
The TD 200 is a text display device that displays messages enabled by the S7-200 CPU.
You do not have to configure or program the TD 200. The only operating parameters stored
in the TD 200 are the address of the TD 200, the address of the CPU, the baud rate, and the
location of the parameter block. The configuration of the TD 200 is stored in a TD 200
parameter block located in the variable memory (V memory) of the CPU. The operating
parameters of the TD 200, such as language, update rate, messages, and message-enabled
bits, are stored in the TD 200 parameter block in the CPU.
Upon power-up, the TD 200 reads the parameter block from the CPU. All of the parameters
are checked for legal values. If everything is acceptable, the TD 200 starts actively polling
the message-enabled bits to determine what message to display, reads the message from
the CPU, and then displays the message.

2.1 Starting the STEP 7–Micro/WIN TD 200 Configuration Wizard
STEP 7–Micro/WIN provides a “wizard” that makes it easy to configure the parameter block
and the messages in the data memory area of the S7-200 CPU. The TD 200 Configuration
Wizard automatically writes the parameter block and message texts to the data block editor
after you finish choosing the options and creating the messages. This data block can then be
downloaded to the CPU. For detailed information about the TD 200 parameter block and
message formats, see Appendix D.
This chapter contains the procedure for creating a sample TD 200 application. Use the
instructions in this example to create a TD 200 parameter block and three messages using
the TD 200 Configuration Wizard. The first message is text only. The second message
contains both text and embedded data. The third message is a text message that requires
acknowledgement by the operator.
The example also shows how to use the function keys to enable a message and how to use
the acknowledge- and edit-notification bits within your program.
To open the wizard, select the menu command Tools "TD 200 Wizard... as shown in
Figure 2-1.
To navigate through the dialog boxes of the wizard, click on “Next>.” At any time during the
procedure, click on the “<Prev” button to go back to a previous dialog box if you need to
change or review any of the parameters you have defined. In the final dialog box, click on
“Finish” to validate and save the parameter block and close the wizard.
You can view the configured parameter block and messages by opening the
STEP 7–Micro/WIN data block editor.
