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.

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, Ian Gillingham |
