Project running on Ignition 7.9.10.
I have a UDT defined where one field in the UDT has an attached alarm. I modified the project recently. Originally, this UDT had two fields with attached alarms. I reduced the number of alarms to 1 and renamed the alarm field (from “In Fault State” to “Faulted”).
The “alarm” field in the UDT is an expression tag. Now, when the bit in the expression for some of the tags becomes active, I get two separate alarms…
One for the current existing tag. xxx/Faulted
One for the old tag structure. xxx/In Fault State
The second tag no longer exists but seems to be cached somewhere. How do I remove these ghost alarms? Or, if they can not simply be removed, how do I rebuild the alarm cache so that these ghost alarms are removed?
