Siemens SINUMERIK 840D sl Programming Manual page 133

The workpiece probe is to be inserted as tool T9 with offset D1.
The radius of the probe ball and length 1
must be entered in the tool offset memory
under T9 D1, before the cycle is called.
Tool type (DP1):
Length 1 - geometry (DP3):
Radius - geometry (DP6):
Length 1 (L1) must refer to the center of
the probe ball: _CBIT[14]=0.
Careful when positioning! Radius R in
length (L1) is ignored. But the desired
calibration height can be entered directly
when calibrating in the abscissa or ordinate
(_MA=1, =2).

Explanation of example
The new trigger value in the minus Z direction is entered in the global data of workpiece
probe 1 in _WP[0,5].
