11 Finding all identifiable Components of a Machine

11.2 MachineComponentsType ObjectType Definition

The MachineComponentsType provides HasComponent References to all identifiable components of a Machine and is formally defined in Table 26.

The <Component> Object has the ModellingRule OptionalPlaceholder and represents the identifiable components of a Machine. As any ObjectType can be used for components, it is of BaseObjectType. As all identifiable components shall contain the Identification Object, <Component> references to that AddIn as defined in Table 27. As a Machine can contain other Machines, it does not reference to the MachineryComponentIdentificationType, but the MachineryItemIdentificationType, which is the abstract supertype of MachineryComponentIdentificationType and MachineIdentificationType.
