Siemens SINUMERIK 840D sl Programming Manual page 297

The calculated offsets are entered in the active D number of the active tool. The offset
strategy is defined via _CHBIT[3] as for measurement.
The measuring cycle generates the approach blocks to the probe and the transverse
motions to measure length 1, length 2 and for the milling cutter, the radius too. A correctly
selected start position is needed.
