Clause 5introduces References, the ProtocolType, and basic TopologyElementTypesneeded to create a communication topology. The types for this model are illustrated in Figure 16.
Figure 16– Device communication model overview
A ProtocolType ObjectTyperepresents a specific communicationprotocol (e.g. FieldBus) implemented by a certain TopologyElement. Examples are shown in Figure 18.
The ConnectionPointTyperepresents the logical interface of a Deviceto a Network.
A Networkis the logical representation of wired and wireless technologies.
Figure 17provides an overall example.
