7.3.2 Extension of MachineryItemState for atmospheric pressure plasma surface treatment machines

For this specification the MachineryItemState defined in OPC UA for Machinery is extended by a SubStateMachine for the State NotExecuting. An exemplary illustration can be found in Figure 11.

Figure 11 - Extension of MachineryItemState for atmospheric pressure plasma surface treatment machines

For this, the AtmosphericPressurePlasmaMachineryItemState_StateMachineType is defined Table 27.
