Hello Experts, I've an S7-400H station that has been recently configured. There are 24 RTU stations (IM153-4PN) connected to the H station in ring topology. 21 of them are connected via ProfiNet cable and 3 IMs are connect via single mode Fiber Optic cable. Normally all RTUs remain stable. However, after a regular interval of around 22 minutes these 3 IMs connected through fiber cable are diagnosed with an error"Module problem or maintenance required".The faults remains for 8-10 seconds and then disappears. Upon inspection of the IM during the error, the communication diagnostics says"error during cable data check". Attached are the screenshots for reference. Any solution that pops up in your mind?
