CI857 INSUM Communication problem.
Could you please help on the below issue.
System : 800xA5.0 SP2
Problem Description : CI857 - 44 qty in use in total 10 AC800M (PM866) controllers. Most of the CI857 cards stops communication suddenly, observed RUN status of the CI857 card was in off condition. When Unplug and plug back the CI857, Run indication and the communication resumes normally and it stops again after 1-2 days. Please refer the attached status code.
Is this known issue or any field alert for this issue?
Will 800xASystem with Firmware upgrade solve this problem?
Its been about 8 years since my insum system was last run, but i recall the following incident around 2007.
We had continuous stoppages just like yours which after a reset ran for a random time and stopped again. We had ABB here and they could not determine from the errors what the cause was.
I eventually grabbed two cisco switches and threw everything else out and problem resolved.
We were using Hirschmann switches originally and after several incidents where weird things occurred (like dropping some IP addresses and not others) i banned them and went Cisco.
