We have a recently installed Ignition Perspective SCADA system. The alarming has been working fine. Few days ago 3 alarms got triggered in the field but did not show up in the Alarm Status table. I went looking in the Alarm Journal and only found their Clear events, and a few months old Active event. So essentially the alarm came in but did not get registered but the clear event was registered. Anyone seen something like this before or any ideas what could be causing this? So far its just these three alarms. Gateway logs are clear around that time the alarm happened.
It is a typical Boolean tag (inside a UDT), no fancy scripting or binding:
Alarm config is enabled, no active delay, and no pipelines.
Alarm Status and Journal have no filters. I can only find the Clear event and not the Active event for these 3 alarms:
And the last Active and Ack events were when we were testing the system:
Querying the alarm database with the eventId gives the same result:
A legacy SCADA was also monitoring the same system and it record the field alarm at about 8:56 am on 9/23
