Dear Experts, We have siemens 400 system with CPU-417-4H with PCS-7 V8.1 The system is commissioned and running from last 3 years. now 1 day before we address the redundancy failure and found CPU in rack-0 goes to STOP mode, and now system is running with SOLO mode with CPU in Rack-1. I have attached the diagnostic log here. from the diagnostic log I understand the memory reset required for CPU. But can I do it online? I have to revert it back to redundant without plant shutdown anyhow? Is it possible? also I exactly want the reason why this CPU goes to stop mode? What shall I do to prevent this in future? I request you please go through attached log file and help me on this points. AttachmentSAIWAN ICS1 DIAGNOSE.txt (46 Downloads) |

Hello niksss, from my point of view the stop occurred due to a memory test error (See event 5 in the .txt). But please create a Support Request including the diagnostic log for this question. Only the Support can give you a verified answer for the reason or a recommendation for preventing it in the future. |
Kind regards |
