Re-Alarming

The Re-Alarming application brings critical and high priority alarms back into focus by re-annunciating them after a configurable amount of time if the condition that caused the alarm still exists.

Administrators can configure analog, status, rate, multistate, and remote point alarms to re-alarm from one to 255 minutes after a Controller acknowledges an alarm.

If the alarm point returns to normal before the re-alarm time period expires, the system removes the alarm from the Alarm Summary dialog box and terminates the re-alarm process. If the point fails to return to normal before the re-alarm time period expires, AVEVA Enterprise SCADA re-annunciates an alarm against the point and processes it as a new event. In the Alarm Summary dialog box, a regenerated alarm appears with some text (for example, "-reAlarm OriginalTimestamp (UTC - UTC-07:00 TimeOffset") to ensure the Controller does not mistake it for a new alarm.

Notes: The functionality applies only to critical and high severity alarms. Other alarms are not affected.

A stale point does not re-alarm. However, if the system generates an instrument failure alarm for a stale analog or rate point, that alarm can be re-alarmed when it is configured as Critical or High severity.

To re-alarm on analog, multistate, and rate points, the alarm message sets of the points should contain the same instrument fail state or else it may not work in both cases if the message set names used are different and do not match the resX key.

Multistate records do not have a state dedicated to an instrument fail condition, and as such, they require additional configuration to have one of the existing states configured to be reported as an instrument fail state.
