Hi there! I'm working on a Ignition 8.1.38 Vision project and I have been through many interesting alarm issues and questions. I created a UDT with a single memory tag for testing purposes.
-
After creating a UDT instance I got a 'Cleared Acknowledged' event displayed on Alarm Journal Table. However, its not stored on DB. Is it possible to avoid this behaviour? If not, how this could be useful?.
-
When an alarm is active, I got a new event displayed on Alarm Journal Table and stored on DB (which is correct). If I disable the UDT instance the alarm disappears from the Alarm Journal Table(As I expected). However, when I enable the UDT instance and the new event is displayed on Alarm Journal Table I got 2 new active events registered on DB with the same eventtime and different IDs. How can I avoid this?. By the way, this behaviour does not occur with OPC tags, but does occur with memory and expression tags.
-
When I reset a tag while it's alarm remains active, a new event is created and stored in DB (with different ID). Is there any way to avoid that?.
Thank you in advance!
