The FiniteStateVariableType is a subtype of StateVariableType and is used to store the current state of a FiniteStateMachine as a human readable name.

The FiniteStateVariableType is formally defined in Table B.5.

Id is inherited from the StateVariableType and overridden to reflect the required DataType. This value shall be the NodeId of one of the State Objects of the FiniteStateMachineType.

The Name Property is inherited from StateVariableType. Its Value shall be the BrowseName of one of the State Objects of the FiniteStateMachineType.

The Number Property is inherited from StateVariableType. Its Value shall be the StateNumber for one of the State Objects of the FiniteStateMachineType.
