I am experiencing issues with the 0-10V output on my ET200s module. The 900A30 module shown in the image is not producing output from the first channel (PQW412), but the second channel (PQW414) is functioning properly. However, when I replace the module with another one, such as the 200A30 module, it is able to output up to 2.7V before going back to 0V. I have also tried replacing both the ET200S module and the base unit, but the issue persists. Despite this, the program on Simatic manager still shows output on PQW412. Currently, I am utilizing a S7-1200 to read values from DB1.DBW456 and DB5.DBD566 and to output it through the S7-1200 analog module.
tientran reported that swapping a module resulted in voltage fluctuations from 0V to 2.7V. Specifically, tientran referenced using the 200A30 module. Will the issue persist with the new module in place? Additionally, there appears to be confusion regarding the use of the S7-1200 system. The supplied photos are from STEP7 Classic, which is not compatible with S7-1200.
When swapping modules, the error does not transfer to the new location. I am utilizing the S7-1200 PLC to retrieve data from the S7-300 PLC using the GET command. Subsequently, I leverage the S7-1200 to generate a 0-10V output based on the retrieved data. Please note that the images provided are from STEP7 Classic, which does not support the S7-1200 system.
It sounds like you've done quite a bit of troubleshooting already! Since you've replaced the ET200S module and the base unit without resolving the issue, it might be worth double-checking the wiring and connections for the PQW412 channel, as intermittent physical connections can sometimes cause similar symptoms. Additionally, considering the configuration in Simatic Manager, make sure that the channel is correctly addressed and typical parameters (like scaling or range settings) are correctly set for the desired output. You could also look into any potential software limits or settings that might be restricting the output. If everything looks good on that front, it might be worth reaching out to Siemens support for more specialized assistance. Good luck!
It sounds like you're really diving deep into troubleshooting that ET200S module! Since you’ve already replaced both the module and the base unit, it might be worth double-checking the wiring and connections for the problematic channel, as loose or faulty connections can sometimes cause intermittent output issues. Additionally, ensure that the configuration settings in the Simatic Manager align with the specifications of your hardware. If the channel appears to be active on the software side but isn’t functioning as expected, consider looking into the possible signal scaling, or even test with a different load to rule out any load-related issues.

Answer: Answer: The issue could be module-specific, as seen with the 900A30 module's first channel (PQW412) not producing output but the second channel (PQW414) functioning correctly.
Answer: Answer: The behavior of the replacement module may indicate a different underlying problem affecting the voltage output.
Answer: Answer: The user has tried replacing both the ET200S module and the base unit, yet the problem persists, indicating a more complex issue.
Answer: Answer: The discrepancy between the displayed output in the program and the actual output suggests a possible software or configuration-related issue affecting the module's functionality.
Answer: Answer: The S7-1200 is utilized to read values from specific data blocks (DB1.DBW456 and DB5.DBD566) and
