Simply clear the alarm on the IOC, i.e., have the PV no longer issue an alarm, and configure the PV on the alarm server as not-latching, so it will automatically clear the alarm indication when the PV returns to OK.

We sometimes use CALC records to combine a "raw" PV with an "alarm_enable" type PV into the actual PV that's fed to the alarm server, so the "alarm_enable" type PV can then be used to stop the alarm. Or use a CALCOUT to update SZV or HIGH or HSV or ... of the record to control how it alarms.

Subject: [EXTERNAL] Phoebus Alarm Server - Alarm acknowledgement from EPICS record

 

I'm trying to find out if there's a way to send commands to the Phoebus
Alarm Server from within EPICS. I have a situation where an alarm should
be able to be acknowledged from an EPICS IOC.

Is there an API that could be tapped into to provide similar behaviour,
as if a user was using the Phoebus Alarm Tree features, but performed
from within EPICS records?

I've scoured as much as I can from searches and Phoebus documentation,
but haven't found anything.

Thanks in advance,
