We’re occasionally seeing alarms that are not being cleared by the system when they are back within normal operating ranges. This happens to both binary and analog type alarms. We’re using the Legacy Alarming system so we can access the alarm data from other scripts and trim off the first portion of the path.
We started seeing this after our upgrade from 7.3.3 to 7.6.1. About a month later, we upgraded to 7.6.3 to try to fix that issue, and it seemed to have worked for some time, but now we’re having issues again.
The alarm still does not clear even if I disable/re-enable the tag and/or alarm. I’ve also tried changing the OPC provider string to force a bad value, and then swap it back with no dice.
There are no “Active Delays” set on these alarms as was the case for this post: viewtopic.php?f=90&t=10261
Any information on this, or is there additional info I can provide to help troubleshoot this?
