The ProductionPartStateMachineTypeshows the states a part can be in and the possible transitions between those states. Their representation in the OPC UA address space is given in Table 54. The name of each transition consists of the names of the states it connects: [FromState]To[ToState].

The ProductionPartStateMachineTypeis formally defined in Table 52.

MachineTool Production ProductionPartStateMachineType

The ProductionPartStateMachineTypeallows to send Eventsof ProductionPartTransitionEventTypewith every transition, as indicated in Table 54. This makes it possible to send all relevant information of the ProductionPartTypethe state machine instance belongs to with the TransitionEvent.

Endedis reached when the production on the part has finished. The PartQualitymay be changed while in this state, implying that the part is measured after the production process. The part does not have to be mounted inside the machine while in this state.

Initializingimplies the part is scheduled for production, but the machining process on the part has not yet started. The part does not have to be mounted inside the machine while in this state.

Runningindicates that the processing of the part within the machine has been started or re-started and is currently running.

InitializingToRunningis triggered when the processing of the part starts. This Transitionrequires the part to be mounted within the machine .

RunningToEndedis triggered when the processing of the part finishes. This Transitiondoes not require an update of the PartQuality.

The states and transitions shall have the numbers indicated in Table 53. The Number property of CurrentState and LastTransition shall use those same numbers for the respective state/transition.
