Identification is used as defined in OPC 40001-1. Shall also be referenced as AddIn in the MachineryBuildingBlocks Folder.

Monitoring is representing a collection of the variables that are assigned to this specific component.

MachineryBuildingBlocks is representing a folder that directly references all those building blocks of the OPC UA for Machinery (OPC 40001-1, OPC 40001-3) which are implemented as an add-in in this specific component.

The components of the WorkpieceMotionDevice have additional references which are defined in Table 54.

RotationSpeed is representing the current rotational speed of the workpiece motion device.

RotationDirection is a descriptive property of RotationSpeed that is representing the current direction of the rotation of the workpiece motion device. True value corresponds to clockwise rotation.

RotationPosition is representing the current rotational position of the workpiece motion device.

ZMotion is representing the information if the motion device is active in the vertical direction. The value true means the motion device is active in the vertical direction.

ZMotionSpeed is a descriptive property of ZMotion that is representing the current speed of the motion perpendicular to rotation plane of the workpiece motion device.

ZMotionPosition is a descriptive property of ZMotion that is representing the current position perpendicular to rotation plane of the workpiece motion device.
