FromStateReferenceType | NodeOPCUA reference documentation

FromState Reference Type

The FromState ReferenceType is a concrete ReferenceType and can be used directly. It is a subtype of NonHierarchicalReferences.

The semantic of this ReferenceType is to point form a Transition to the starting State the Transition connects.

The SourceNode of this ReferenceType shall be an Object of the ObjectType TransitionType or one of its subtypes. The TargetNode of this ReferenceType shall be an Object of the ObjectType StateType or one of its subtypes.
