For some reason the forum is only allowing me to upload one image. Attachment Screenshot 2025-08-12 083839.jpg (232 Downloads)

In my case besides configuring the AI to current and assigning addresses I haven't changed anything from default. If i restart the PLC it clears but comes back eventually. I have solved it by closing the cabinet and not looking at the LED, open to better suggestions

Those reported problems should eventually get corrected with either a portal update, or firmware update, or possibly both. In the interim, Siemens Support might suggest loading the configuration data to the Ai module at PLC startup - and perhaps again should the Diag Error Interrupt OB get called for the exact same problem. Then your PLC logic can react by sending the configuration data to the module again. alanTI I am just here to say that i have the exact same hardware and issue.

Please create a Support Request from this web page and have the team from Siemens support you. They will be able to call up the design team to assist, if needed. BUT do make sure you have the newest Step7 V20 update loaded. There is also at least one HSP that has something to do with the S7-1200 G2. Load the HSP's that are available for the hardware you are using. If in doubt - ask Siemens about that also. @Hati: As far as I am aware, the S7-1200 G2 does not have Configuration Control at this point in time. It was promised in the next iteration of the platform. (I do hope Step7 does not have that configurations already available, since I will not work AFAIK.)
