The ProtocolType ObjectType and its subtypes are used to specify a specific communication (e.g. FieldBus) protocol that is supported by a Device (respectively by its ConnectionPoint) or Network. The BrowseName of each instance of a ProtocolType shall define the Communication Profile (see Figure 18).
Figure 18 shows the ProtocolType including some specific types and instances that represent Communication Profiles of that type. It is formally defined in Table 36.
