7.3 AtmosphericPressurePlasmaSurfaceMachineType ObjectType Definition

7.3.1 Overview

The AtmosphericPressurePlasmaSurfaceMachineType ObjectType is the representation of a plasma surface treatment machine that performs surface treatment at atmospheric pressure. The AtmosphericPressurePlasmaSurfaceMachineType is a SubType of the PlasmaSurfaceMachineType. This implies that all nodes of the PlasmaSurfaceMachineType are inherited by the AtmosphericPressurePlasmaSurfaceMachineType. The AtmosphericPressurePlasmaSurfaceMachineType is formally defined in Table 25.

The components of the AtmosphericPressurePlasmaSurfaceMachineType have additional subcomponents which are defined in Table 26.

PlasmaJet is representing the unit that generates the plasma required for the process.

NOTE: The LowPressurePlasmaSurfaceMachineType is a subtype of the PlasmaSurfacemachineType. The additional subcomponents mentioned above are refering to the mandatory Components of the PlasmaSurfacemachineType which is inherited to the LowPressurePlasmaSurfacemachineType.

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.

For this, the AtmosphericPressurePlasmaMachineryItemState_StateMachineType is defined Table 27.

7.3.3 AtmosphericPressurePlasmaNotExecutingSubState_StateMachineType ObjectType Definition

The AtmosphericPressurePlasmaNotExecutingSubState_StateMachineType is used for a SubStateMachine which divides the NotExecuting State into Idle and Standby. This SubStateMachine is not active if the parent State Executing is not active. In this case the CurrentState and LastTransition Variables of the AtmosphericPressurePlasmaNotExecutingSubState state machine shall have a status equal to Bad_StateNotActive.

The AtmosphericPressurePlasmaNotExecutingSubState_StateMachineType is formally defined in Table 29.
