Hi, Strange. Anyways, to start with have a look at this manual SIMATIC Fault-tolerant systems S7-400H under chapter "Link-up and update" also " System modifications during operation ". Maybe channel pasivation have something to do with as well, you can read about this for example in SIMATIC Industrial Software S7 F/FH Systems - Configuring and Programming . If you zip your diagnostic data, you can upload all data in one package. The diagnostic buffer will help other forum users to see what is going on. So please upload all the data you have and maybe someone can give you some ideas where to look! |

Hi MicroMan, Thank you very much for your response, I really appreciated. Yes, it is very strange, our local Siemens Indonesia came here 5 month ago, They had try to find out what is the problem, but still not able to get the answer. I understand our local guys have very lack experience of our problem. Because we are the only plant in Indonesia that use PCS7 with redundant system. At moment the controller are running good, switching is good. The problem will occure only when the CPU restart together in the same time or small delay between them. Here I attached diagnostic buffer from CPU Rack0, hope other user can give me some light.

Hi, Thank you for the buffer. I had a quick look, there is a lot of info in the buffer. It is flood of entries, anyways I noticed entries related to corrupted Safety Data Format. That happens after the H-system goes to Redundant mode: "Event 97 of 3000: Event ID 16# 75E1 Safety Program: Error in.... Event 106 of 3000: Event ID 16# 43E2 Change from update mode to operating mode RUN (redundant mode) Previous operating mode: UPDATE" I think there is something along that line... There is not harm to double check your settings and system integrity. You can use the SIMATIC Process Control System PCS 7 Compendium Part B - Process Safety as guidance. Well:
I hope I could help a bit. |
