The OPC UA ReferenceType Controls is used to describe dependencies between objects which have a controlling character. The BrowseName Controls and the InverseName IsControlledBy describe semantically the hierarchical dependency e.g. a controlling device Controls a controlled machine module.

Example for usage in this companion specification: If one controller Controls several motion devices, each motion device IsControlledBy the same controller.

The SourceNode of this type shall be an ObjectType or Object and the TargetNode shall be an Object.
