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