Identification is used as defined in OPC 40001-1. It represents numerous identification features of the system.

Components is representing a collection of all physical components of the Surface Technology System.

Monitoring is representing a collection of ObjectTypes and VariableTypes, representing the current state of the process, that are not assigned to a component but to the overall system. The Monitoring of the overall system may contain specific process values of its components.

MachineryBuildingBlocks is representing a folder that directly references all those building blocks of the OPC UA for Machinery (OPC 40001-1, OPC 40001-3) which are implemented as an add-in.

Description is representing a collection of ObjectTypes and VariableTypes that describe the overall system. This may be information that is not an identifier for the system or that is static in character but must be stored on the server for some use cases. One example is the mesh size of a sieve, which does not vary but can be queried by cooperating systems.

The components of the STSysType have additional references which are defined in Table 16.
