Figure B.5 illustrates the base model used for illustrating AddIns. This base model is similar to the base model for Interface but removed the IVendorNameplateType.


Figure B.5 – Base Information Model for examples

AddIns are used to attach OPC UA FX Information Model-specific content to an existing OPC UA Information Model. This is possible on the type definition level or the instance level. Only the type definition level is illustrated. The instance level would be identical, just applied to an instance instead of a type.
