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.

In Part 1 in general all variables and properties are read only unless stated otherwise in the description. A vendor can decide to provide variables or properties as writeable by client side as well.
