The MachineIdentificationType is defined in OPC UA for Machinery (OPC 40001-1) and provides basic information on a machine/device.
For the InstanceDeclaration the ModellingRules of the Properties Model and DeviceClass are overridden to mandatory and the Property ControllerName is added.
The Object MachineryBuildingBlocks contains building blocks from OPC UA for Machinery as defined in OPC 40001-1. For this version of OPC 40084-1, the Object uses the two AddIns MachineryItemState and MachineryOperationMode, where for the first a sub-state machine with substates for Executing is added.

The ControllerName Property represents the name of the machine controller (e.g. “CP22xx”).
For this specification the MachineryItemState defined in OPC UA for Machinery is extended by a SubStateMachine for the State Executing.
Figure 4 – Extended MachineryItemState
For this, the ExtrusionMachineryItemState_StateMachineType is defined in Table 3.

ExtrusionExecutingSubState |
The ExtrusionExecutingSubState_StateMachineType is used for a SubStateMachine which divides the Executing State into ReadyToRun, ManualRun and ControlledRun. This SubStateMachine is not active if the parent State Executing is not active. In this case the CurrentState and LastTransition Variables of the ExtrusionExecutingSubState state machine shall have a status equal to Bad_StateNotActive.
