This specification defines several building blocks for various use cases in the context of machinery. The specification uses the AddIn concept defined in OPC 10001-7, in order to allow companion specifications and vendors to easily apply individual building blocks.
This is exemplified in Figure 6. On the right side of the figure you can see ObjectTypes defining specific functionality like Identification. This includes the definition of a default BrowseName. On the left side you see an example of how such a building block is used. This type could use other building blocks as well.
