The AuxiliaryComponentType describes components mounted in a controller cabinet or a motion device e.g. an IO-board or a power supply.

It is formally defined in Table 42.

This type should not be used for instances of components which represent a motor, a gear or a drive For these components this specification describes specific types.

The ProductCode property provides a unique combination of numbers and letters used to identify the product. It may be the order information displayed on type shields or in ERP systems. This property is derived from ComponentType defined in OPC UA DI.

The AssetId property is a user writable alphanumeric character sequence uniquely identifying a component. The ID is provided by the vendor, integrator or user of the device. It contains typically an identifier in a branch, use case or user specific naming scheme.

This could be for example a reference to an electric scheme. For electric schemes typically EN 81346-2 is used.

An use case could be to build up a location oriented view in a spare part management client software. It enables to identify parts with the same article number which is not possible if this entry is not used.

This property is defined by ComponentType defined in OPC UA DI.
