To ack alarms from an Objekt I normally use a Control Modul Variable to rest the alarm in the Control Builder. But now I would like to ack the alarms with the Alarm List Property. Like the command in the tool "Ack all Visible Alarms" in the Alarm List. Where I can find the code from this Button "Ack all visible Alarms"? I try to set the Property "Alarm List:IsUnAck" to 0. In some object it works but in some object not. What would be de right way to ack this alarms without using variables in the control builder?
On objectlevel, writing false (0) to AlarmGlobalProperties:IsAlarmUnAck is equivalent to clicking the triangle (AlarmControl) of the object’s faceplate. Acknowledge all alarms associated with the object.
The Alarm List property is filtered, i.e. may not contain all alarms.
I don’t know what writing false (0) does: maybe it acknowledged the filtered alarms?
The operate permission is required (on each object) to acknowledge an alarm; the user must have this on all objects in a list to acknowledge the complete list.
PG2 Acknowledge All Visible alarms send ack to all embedded objects.
