Both PM865 went to fault together. CI Log shows Modulebus CRC error.
At one of our sites Both PM865 HI controllers went to fault simultaneously. I have attached the logs for reference.
The only error i can see is in CI log.
E 2016-10-12 03:06:45.128 (INTERRUPT)[ERRORHANDLER] Trigger ErrorHandler. Msg="Modulebus: Incoming CRC error". Status=0x00000042 (0:66) !VxWorks!
I 2016-10-12 03:06:45.128 (EHTask)[ERRORHANDLER] Send ErrorReport to PM. ('Modulebus: Incoming CRC error', Sev = 2, ActionsToTake = 0x1)
Does anyone know the meaning of these errors?
Any indication as to why both controllers went to fault simultaneously from the logs?

Please contact ABB support in your region for support on this problem. The primary CPU log file is unfortunately overwritten by the Heap stat and other tests performed by you before fetching the log. When reporting the problem, please include the broadcasted logfiles found in any PC running the MMS server and connected to the Control Network.
