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. If the FiniteStateMachine is subtyped, it shall be the NodeId of the State defined on the supertype, i.e., where the State is defined the first time in the type hierarchy.

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.
