Events are not generating but alarms are generating_5.1 Rev D
Hi All, I have a unique issue with 5.1 Rev D. I have 1 redundant server. It was working fine but when I restarted secondary server its OPC went down. After boot up process we restarted the OPC. After this we observed the alarm list is updating but events list os not updating at all for process alarms. We found in Primary server Data Access OPC is connected (with Smilie) but Alarm & Event OPC was down & even after trying to connect it is not getting healthy.
My question is when secondary is healthy then why events are not generating. How come alarms are generating. ?
Is their any other method apart from restarting the server to resolve this issue ?
Anything i need to check or do in 800xA without restarting.

Process alarms (Condition Events) and events (Simple Events) take same route from PLC > OPC Server > Event Collector > Alarm Manager. The Alarm Manager pushes all as events to Event Storage which keep a history on disk.
If you see alarms but no events in 800xA alarm and event lists, it sounds like a break between the Alarm Manager and Event Storage services.
This is a rather complex matter to explain in a few words on an open Internet forum, I hence recommend that you ask your regional ABB support center to file a support case.
