Alarm Suspicious Events

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.

  1. 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?.

  2. 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.

  3. 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!
