Warranty Information
Warranty information is not explicitly detailed in this section of the manual.
\n The S7-200 TD devices (TD 200 and TD 200C) 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 that allow you 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.
Features of the TD Devices include designing hierarchies of user menus and screens, displaying alarms, modifying designated program variables, forcing I/O points, and viewing CPU status.
The TD 200C offers additional functionality such as changing the S7-200 CPU operating mode and accessing/editing CPU memory. Both devices support multiple languages and character sets. Installation involves mounting the device, connecting it to the S7-200 CPU, and configuring it using STEP 7-Micro/WIN tools like the TD 200 wizard and Keypad Designer for the TD 200C.

Troubleshooting and error codes
| Problem | Possible Cause | Possible Solution |
|---|---|---|
| NO PARAMETER BLOCK | The TD 200 could not find a parameter block in the programmable logic controller. | Configure a parameter block for the TD 200 in the S7-200. |
| The TD 200 found a parameter block in the programmable logic controller, but it contains errors | Be sure the parameter block address in the TD 200 matches the actual address of the parameter block. Be sure all fields are within range Be sure all addresses are valid for the S7-200 CPU |
|
| CPU NOT RESPONDING | Address of the S7-200 CPU is incorrect | Correct the address error |
| S7-200 CPU does not have power | Power up the CPU | |
| Cable problems | Check the cable connections | |
| Wrong baud rate configured | Correct the baud rate configuration Refer to Appendix B |
|
| Multiple CPUs at the same address | Remove other CPUs and retry Refer to Appendix B |
|
| May need network terminations | Refer to Appendix B | |
| Network too long or too many devices on network | Refer to Appendix B | |
| HARDWARE ERROR | TD 200 is inoperable | The TD 200 could be defective Replace with a new module |
| NETWORK ERROR | TD 200 cannot establish a network connection or enter an existing network | Multiple masters with the same address. Remove other masters and retry |
| Cable problems | Check the cable connections | |
| Multiple CPUs at the same address | Remove the other CPUs and retry | |
| CPU BUSY | Some other master has locked the S7-200 CPU by uploading or downloading a program to that CPU | Wait — The message disappears in a few seconds |
| CPU IN STOP MODE | RUN/STOP switch is in STOP | Put CPU in RUN mode |
| CHARACTER SET ERROR | You selected a character set which is not supported | Use the TD 200 wizard to select a valid character set |
| Display backlight is on, but no message is displayed | Program checksum failure | Defective hardware: Replace with a new TD 200 or TD 200C |
