FunctionalEntityType is the base type for the definition of all functionality in an OPC UA FX Information Model. A FunctionalEntity can provide InputData, OutputData, ConfigurationData, diagnostic information and Methods for manipulating or sharing the data. It is expected that other models will subtype the FunctionalEntityType. It can have SubFunctionalEntities and relationships to other Objects defined in this model or other models. A FunctionalEntity may be implemented using the IFunctionalEntityType Interface. It does not need to be an instance of FunctionalEntityType or an instance of a subtype of FunctionalEntityType.
The FunctionalEntityType is illustrated in Figure 24.
