13.2 MachineryOperationModeStateMachineType

The MachineryOperationModeStateMachineType is a subtype of FiniteStateMachineType defined in OPC 10000-16. The semantic of this AddIn is to provide the MachineryOperationMode of a MachineryItem. It is formally defined in Table 32.

The States and Transitions define a StateMachine as shown in Figure 17. It does not define an initial State, i.e., the initial State is vendor-specific.

Note: None of the States or Transitions have a ModellingRule, i.e., they are only provided in the TypeDefinition, not on the instance. The CurrentState Variable (inherited from StateMachineType) contains the information of the current State of the instance.

The None State represents that there is currently no MachineryOperationMode available for the MachineryItem.

The Maintenance State represents that the MachineryItem is set into maintenance mode with the intention to carry out maintenance or servicing activities of the MachineryItem.

The Setup State represents that the MachineryItem is set into setup mode with the intention to carry out setup, preparation or postprocessing activities of a production process.

The Processing State represents that the MachineryItem is set into processing mode with the intention to carry out the value adding activities.

The meaning of the Transitions is defined in the Description of Table 33.

The InstanceDeclarations of the MachineryOperationModeStateMachineType have additional Attribute values defined in Table 33.

The components of the MachineryOperationModeStateMachineType have additional References which are defined in Table 34.
