AMS Alert Monitor: Alarms are continuously appearing (latched) in Active Alarm list even after the instrument is healthy


In AMS Alert monitor Active alarm panel, Many alarms continuously appearing (latched) even after the instrument become healthy in all respect.

For example, "No Communication" Alarm is active, While I can scan the instrument, open the Instrument configure faceplate, Configure, verify the diagnostics. This confirms all the parameter's are healthy.

Part of trouble shooting, we tried following:

1. Download the charm.

2. Download the control module.

3. Instrument power recycled. 

But still the alarm remains same. I can say approximately 500 alarms. This issue is not specific to one instrument model / type. It happens for many models (2 wire / 4 wire transmitters, Fisher valve's and others) connected to different controller. And this is noticed from the commissioning of the system.

  • Hello, what version of AMS DM and DeltaV is this on? It looks like you might have somehow change the tag or you moved the device to a different charm doing commissioning and now AMS has a different path and causing this issue. I would recommend you removed/delete those tags using AMS remove device command for those tags and rescan all devices again to sync DeltaV and AMS devices with charms.
    I hope this helps.
