This ReferenceTypecan be used to expose that two different Nodesin the AddressSpacerepresenting the same functionality. It refines the RepresentsSameEntityAs ReferenceTypeand defines that the same entity in the real world shall be a functionality. For example, the functionality to move an axis might be provided by an Objectrepresenting a function block of a PLC with that functionality, but also be an Objectrepresenting the functionality of a drive. The ReferenceTypecan be used to related both Objects.

The RepresentsSameFunctionalityAs is a concrete ReferenceTypeand can be used directly. It is a subtype of HierarchicalReferences. It is a symmetric Reference, that is, it provides the same semantic in both directions.

The semantic of this ReferenceTypeis to relate two Nodesthat represent the same functionality.

The SourceNodeof Referencesof this ReferenceTypecan be of any NodeClass.

The TargetNodeof Referencesof this ReferenceTypecan be of any NodeClass.

Both, SourceNodeand TargetNodeshall represent the same functionality.

RepresentsSameFunctionalityAs is formally defined in Table 9.
