In Figure 36, an example is given, where Objects are used as Notifications. The ObjectType X:ManualActivityType provides a notification that some manual activity (like the change of a tool in a machine tool) is needed. It provides information about the activity and when it is expected to be done. Whenever the machine predicts the need for such an activity, such an Object is created on the Notifications Object. The 0:NodeVersion Property can be used to identify such new Objects as a Client. After the action has been executed, the Notification Object will be removed.
