Active status of channel. See 7.2.4 for further description of possible states.

6.6.3.24 BlockMode

Block mode status (true in case of block mode is active, else false). With block mode active, individual program blocks are processed one by one. Each step has to be triggered by the operator.

6.6.3.25 CmdFeedrate

Feedrate setpoint value.

6.6.3.26 CmdOverride

Override setpoint value.

6.6.3.27 DryRunFeed

Feed status (true in case of feed hold active, else false).

6.6.3.29 Id

Unique numeric channel identifier.

6.6.3.30 PosTcpBcsA

Actual position of the tool center point in machine’s Cartesian base coordinate system. The tool center point is the reference point on a tool how it is considered by the CNC’s tool compensation function. If there is no tool present, the tool center point is the tool carrier zero point.

6.6.3.31 PosTcpBcsB

Actual position of the tool center point in machine’s Cartesian base coordinate system. The tool center point is the reference point on a tool how it is considered by the CNC’s tool compensation function. If there is no tool present, the tool center point is the tool carrier zero point.

6.6.3.32 PosTcpBcsC

Actual position of the tool center point in machine’s Cartesian base coordinate system. The tool center point is the reference point on a tool how it is considered by the CNC’s tool compensation function. If there is no tool present, the tool center point is the tool carrier zero point.

6.6.3.33 PosTcpBcsX

Actual position of the tool center point in machine’s Cartesian base coordinate system. The tool center point is the reference point on a tool how it is considered by the CNC’s tool compensation function. If there is no tool present, the tool center point is the tool carrier zero point.

6.6.3.34 PosTcpBcsY
