Hi Tanvi,

 

Have you tested against the codebase that with this PR (https://github.com/ControlSystemStudio/phoebus/pull/2303) gets merged or not?

 

Thanks,

Tong

 

Hello,

 

I ran a few tests and found the problem only occurs if alarm delay for test_alarm PV is set to a non-zero value. It does not matter if the test_alarm PV is configured to be latched or unlatched.

 

When alarm delay is non-zero, PV (in an alarm state) on getting re-enabled (using filter) goes into OK state and hence don’t show up on the alarm table. Until an alarm event (such as alarm state change or acknowledge action) happens on the PV, PV is seen to be stuck in OK state in alarm tree and don’t show up on alarm table.
