The functional model is required to be able to be applied to existing Information Models. These models have defined their own Object Models and their own hierarchy of Objects. OPC UA does not support multiple inheritance. By defining the IF unctionalEntityType Interface, the OPC UA FX Information Model can be applied to any existing Object, adding the required IF unctionalEntityType items into the existing Information Model.
The IFunctionalEntityType Interface is formally defined in Table 100.
