Calling the
Inactivate method over the
inactive alarm has no effect. An
active alarm is inactivated. The behaviour of the alarm during the inactivation is specified in the "
Inactivate type" configurator.
If there are several instances of the alarm item with the same identifier (caused by states of alarm items inactive unacknowledged (blue)), then the last, the latest old alarm item is inactivated.
After the attempt to inactivate non-existing alarm item (wrong
sId parameter), an error occurs
in the INFO system only if in the corresponding
PmaAlarmGroup object there is no alarm item with the checked configurator "
Template for dynamically created items" (it means that all alarm items of the
PmaAlarmGroup object are statically configured).
The method is
synchronous, it means that it is processed immediately by the alarm subsystem. Nevertheless writing the history to disk is
asynchronous, it means that this method passes the request for writing to the history to the alarm subsystem, it is placed into the queue of requests and it is processed later by the alarm subsystem.
