12 OPC UA Reference Types
12.1 HasOpticalPathTo
The HasOpticalPathTo is a concrete ReferenceType and can be used directly. It is a subtype of NonHierarchicalReferences. This ReferenceType is asymmetric and allows looping (See Annex B.9).
The semantic of this ReferenceType is to link two components with an optical path in between them
The SourceNode of References of this type shall be an Object or ObjectType representing a component.
The TargetNode of this ReferenceType shall be an shall be an Object representing a component.
The HasOpticalPathTo is formally defined inTable 72.

12.2 TransmitsDataTo
The TransmitsDataTo is a concrete ReferenceType and can be used directly. It is a subtype of NonHierarchicalReferences. This ReferenceType is asymmetric and allows looping.
The semantic of this ReferenceType is to link two components where data is being transmitted from one component to the other.
The SourceNode of References of this type shall be an Object or ObjectType representing the data source.
The TargetNode of this ReferenceType shall be an shall be an Object representing the data sink.
The TransmitsDataTo is formally defined in Table 73.
