Data Item type/subtype Description
ACTUATOR_STATE The state of the Actuator - ACTIVE or INACTIVE.
ALARM DEPRECATED: Replaced with CONDITION category. Rel. 1.1.
ACTIVE_AXES The set of axes associated with a Path that the Controller is controlling. If this

DataItem is not provided, it will be assumed the Controller is controlling all axes.

AVAILABILITY Represents the ability of a Component to communicate. This MUST be provided for a Device and MAY be provided for any other Component. AVAILABLE or UNAVAILABLE.
AXIS_COUPLING Describes the way the axes will be associated to each other. This is used in conjunction with COUPLED_AXES to indicate the way they are interacting. The possible values are: TANDEM, SYNCHRONOUS, MASTER, and SLAVE. The coupling MUST be viewed from the perspective of the axis, therefore a MASTER coupling indicates that this axis is the

master of the COUPLED_AXES.

CHUCK_INTERLOCK The indication of an interlock or control state to prevent CHUCK from being operated. ACTIVE or INACTIVE
MANUAL_UNCLAMP The indication of an operator controlled interlock which can inhibit the unclamp action of an electronically controlled chuck. ACTIVE or INACTIVE
CHUCK_STATE The state of a mechanism that holds a part, stock material, or any other item in place. OPEN, CLOSED, or UNLATCHED

CONTROLLER_MODE_OVERRIDE A setting or selection that changes the behavior of a piece of equipment.
DRY_RUN Test mode used to confirm execution of machine functions. No part is produced and spindle operation is suspended. ON or OFF
SINGLE_BLOCK Program execution is paused after each block of code. ON or OFF
MACHINE_AXIS_LOCK Program execution is normal, but no equipment motion occurs. ON or OFF
OPTIONAL_STOP Program execution is stopped after a specific program block is executed. ON or OFF
TOOL_CHANGE_STOP Program execution is paused when a command is executed requesting a tool change. ON or OFF
COUPLED_AXES Refers to the set of associated axes. The value will be a space delimited set of axes names.
DIRECTION The direction of motion. CLOCKWISE or COUNTER_CLOCKWISE
ROTARY The rotational direction of a rotary device using the right hand rule convention as defined in Appendix B. CLOCKWISE or COUNTER_CLOCKWISE
LINEAR The direction of motion of a linear device. POSTIVE or NEGATIVE
DOOR_STATE The opened or closed state of the door. OPEN, UNLATCHED, or CLOSED.
END_OF_BAR Indicates whether the end of a piece of bar stock has been reached. YES or NO
PRIMARY If one or more locations on a piece of bar stock are referenced, the main or most important must be designated as PRIMARY.
AUXILIARY When multiple locations on a piece of bar stock are referenced, additional locations must be designated as AUXILIARY.
EMERGENCY_STOP The current state of the emergency stop actuator. ARMED (the circuit is complete and the device is operating) or TRIGGERED (the circuit is open and the device MUST cease operation).
EQUIPMENT_MODE An indication that a piece of equipment is performing specific types of activities.
LOADED Equipment is under load. ON or OFF
WORKING Equipment is performing any activity. ON or OFF
OPERATING Equipment is powered or performing any activity. ON or OFF
POWERED Primary power is applied to a piece of equipment. ON or OFF
DELAY Equipment is waiting for an event or action to occur. ON or OFF
EXECUTION The execution status of the Controller. READY, ACTIVE, INTERRUPTED, FEED_HOLD, STOPPED, OPTIONAL_STOP, PROGRAM_STOPPED, or PROGRAM_COMPLETED
