TransitionEventType | NodeOPCUA reference documentation

The TransitionEventType is a subtype of the BaseEventType. It can be used to generate an Event identifying that a Transition of a StateMachine was triggered.

The TransitionEventType inherits the Properties of the BaseEventType.

The inherited Property SourceNode shall be filled with the NodeId of the StateMachine instance where the Transition occurs. If the Transition occurs in a SubStateMachine, then the NodeId of the SubStateMachine has to be used. If the Transition occurs between a StateMachine and a SubStateMachine, then the NodeId of the StateMachine has to be used, independent of the direction of the Transition.
