5.8.13 PlaceInService Method ToC Previous Next

The PlaceInService Method is used to set the OutOfServiceState to False of a specific Alarm instance. It is only available on an instance of an AlarmConditionType that also exposes the OutOfServiceState. Normally, the NodeId of the ObjectInstance is passed as the ObjectId to the Call Service. However, some Servers do not expose Condition instances in the AddressSpace. Therefore, Servers shall allow Clients to call the PlaceInService Method by specifying ConditionId as the ObjectId. The Method cannot be called with an ObjectId of the AlarmConditionType Node.
