hello. Dear experts,I posted a question due to communication failure between ET200SP and S7-1500 CPU.Below, I have uploaded the diagnostic buffer for the communication problem I had as an attached file. PLC and 3 ET200SP modules configured as redundant are connected through SCALANCE.Connected through MRP RING structure. However, among the ET200SP modules, there is a module consisting of an output card and an analog card. More than once a day, if there is a communication failure of several milliseconds, the recovery process is automatic. I contacted Siemens and set the CPU's communication load value to 50%, and tried increasing the module's update time and watchdog time. (Of course, I didn't know how much to increase it, so I set the update time to 4ms) The communication cable was also changed to cat6 grade cable. However, the problem was not resolved, so I decided to post a question like this. I hope experts can help. thank you AttachmentDiagnostics.txt (168 Downloads) |
