A «digital» variant may be used to explore possible or anticipated changes to a «physical»
PhysicalEntitythat is mapped by a unique «digital»
@Entity, but it not a direct part of the control loop of the «twin»
DigitalTwin. It may, however, be used by the control system as an idealised target for driving the «physical»
PhysicalEntityinto a desired position (against which the unique «digital»
@Entitymust then be synchronised).
