ErrorHandler PM: 4189 Incoming CRC Error

Good day!

We have redundant pair of PM865 controllers. In a primary controller log a lot of errors:

"ErrorHandler PM: 4189 Incoming CRC Error adr 0xd2 (1,2)". What does this message mean?

Thanks for advance

We have a similar situation, in our case the redundant PM865 crashed.

Error message from the primary controller is as follows;

ErrorHandler PM: 4189 Incoming CRC Error adr 0x12 (1,2)

Any ideas on this..

Thank you.

I had been going through some supportline cases, and found that this might be an issue with the Module bus (fibre optic cable or the cluster modem). Refer this bulletin to see if the module is affected or not 3BSE079875_A_en_S800_I_O_-_AI880A_DI880_DO880_communication_problem.

Hope this helps.
