The Alarm Audit types indicate either the state of an alarm, or the action taken against an alarm.

Audit Type Number

Audit Type Name

Description

0

AUDIT_UNKNOWN

The value is either unknown or not set. This may occur when the system receives audits replicated from an older system via Datapump that does not have the audit type data.

1

AUDIT_NORMAL

This is a return-to-normal (RTN) alarm condition. The record in question returns from an abnormal state to a normal state.

2

AUDIT_INIT

The first alarm for a category against a point. This type is also used for system alarms.

3

AUDIT_CHANGE

Subsequent alarms for a category against a point.

4

AUDIT_ACK

The alarm has been acknowledged. The alarm has been deleted if non-persistent.

5

AUDIT_PARK

The alarm has been parked. In the case of pre-parking, the parked alarm might be the first alarm on the point.

6

AUDIT_UNPARK

The alarm has been unparked.

7

AUDIT_PURGE

The alarm has been purged because its purge timer has run out.

8

AUDIT_DELETE

The alarm has been deleted. This can occur if the RealTime database (RTDB) almsum table is completely full and the system needs to delete a lower-priority alarm to make room for the insertion of a higher-priority alarm. It may also occur if a record for a telemetered point is deleted while in an alarm condition, which in turn causes the system to remove the orphaned alarm.

9

AUDIT_DELETE_INHIBIT

The alarm has been deleted due to a timed alarm inhibit.

10

AUDIT_UNACK

The alarm has been set to the unacknowledged state, possibly as a result of test mode deactivation.
