Activate - method of object PmAlarmEvent

The activation of an existing alarm/event item (PmAlarmEventItem object).
Activate(sId As String, [sComment As String], [tTimeOn As Date])
oAlEv.Activate sId, sComment, tTimeOn
sId(String) The unique text identifier of the alarm/event item. See the configurator "Identifier".
sComment[optional] (String) The text note that is stored into the data together with the activated alarm/event item (it is enabled on the Storage page).
tTimeOn[optional] (Date) The activation time of the alarm. If not used, the activation time equals to the time of calling this method.
Calling the Activate method over the active alarm has no effect. An inactive alarm is activated. The behaviour of the alarm during the activation is specified by the Inactivate type configurator.

If there are several instances of the alarm/event item with the same identifier (caused by alarm/event states inactive unacknowledged (blue)), the last, the latest old, item is activated.

After the attempt to activate non-existing alarm/event item (wrong parameter sId), an error arises in the Info system only if in the corresponding object PmAlarmEvent there is no alarm/event item with the set configurator Template for dynamically created items (i.e. all alarm/event items of the PmAlarmEvent object are statically configured).

The method is synchronous, i.e. it is processed immediately by the alarm subsystem. Nevertheless writing the history to disk is asynchronous, which 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.
