PM856 Controller - The controller has been shutdown due to an unrecoverable fatal state!!
Hi ABB Support Team,
We encountered a PLC Shutdown on our ABB PM856 Controller. Need your help to know the cause of the shutdown. Please see attached Controller Log for your reference.
If I was forced to guess, I'd Ethernet networking is involved somehow. In the past, incoming TCP Reset messages could lead to problems in a controller.
I strongly recommend asking your regional ABB Support organization to create a support case and open an investigation into the matter.
