Redundancy of IAC communication between redundant SIL and non-SIL controllers
I have a problem regarding the redundancy of IAC communication between redundant SIL and non-SIL controllers. When I turn of the primary ethernet connection to controller, the IAC is completely lost and I have to completely turn off/on the controller to restore the IAC again.
Would you have a time to analyse and could you have any idea how to resolve a problem?
Here is a link of my question. The question also contains controller logs: https://forum-controlsystems.abb.com/...
Thanks in advance!

I have not seen this particular error myself. I do sometimes work with the AC 800M, but there are persons here on the AKS forum that are better fitted to answer this question concerning AC 800M firmware.
If you don't get the feedback you expect, I recommend taking the formal support route: contact your regional ABB support center.
After all, AKS is only an open forum on the Internet where anyone with an email address can join and download information. Not to be mixed up with ABB's formal support.
