Hi, We have a working H-System. CPUs are 414-4H FW 3.0.1 Recently we are facing the STOP of CPU0 with event ID#4546. I could not understand you mentioned about connector with bend pins, can you elaborate which connectors. Also we observed there was a faulty Sync module and hence we replaced one Sync Module and also FO cable. But the problem still persist and the CPU0 goes to STOP whether it is kept as Master or Reserve. I have observed that the Diagnostic buffer is different when the CPU is Reset and put in operation. I have attached both Diagnostic buffers (during when CPU fault exist and after MRES). also attached Config export. Can the Memory card (RAM) be faulty? will it help if I replace Memory card? System is not having any vibration etc. System was running normal for months and recently no modifications done. Thanks, Arunkumar Splitted from Urgent !!!! Diagnostic S7-400 H.

I thing - problem with internal memory. after RunPLC copyed programmfrom external load memory (memory card) to work memory. Programm execute from work memory. Additional thoughts: I saw an error when "Configuration in RUN". Maybe we should update firmware: http://support.automation.siemens.com/WW/view/en/6741018. Last firmware version V3.1.5, your -Firmware V 3.0.1 |

Hi, Thanks, You are correct, already the error reappeared and I swap the CPU with another healthy installation with due care. Regarding FW update, may be we will differ it for sometime as we have asked customer to go for CPU upgradation andis in his consideration. Thanks for your time, Arunkumar |
