Each <SubUnit> object with Interface IWwBaseStateType shall be put into this object. It represents an instance of a state. For example, a CNC machine can have two places where independent jobs are produced. Then there are two <SubUnit> Objects. They may be named “Place_1” and “Place_2”.
The components of the IWwSubUnitsType have additional subunits which are defined in Table 17.
