The Enable Method is used to change a Condition instance to the enabled state. Normally, the NodeId of the object instance as the ObjectId is passed to the Call Service. However, some Servers do not expose Condition instances in the AddressSpace. Therefore, all Servers shall allow Clients to call the Enable Method by specifying ConditionId as the ObjectId. The Method cannot be called with an ObjectId of the ConditionType Node. If the Condition instance is not exposed, then it may be difficult for a Client to determine the ConditionId for a disabled Condition.
