The CraneMotionDeviceSystemType is used as the root object representing the motion device system with all its subcomponents. The CraneMotionDeviceSystemType is derived from the MotionDeviceSystemType (OPC UA for Robotics) as a subtype of the ComponentType (OPC UA for Devices). For MachineryItemIdentification OPC UA for Machinery is applied, see Figure 8.
