5.1 Overview
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.)
