There is no extension with 0, even if the program number has less than 4 digits. A program number with more than 8 digits
leads to an alarm.

Measuring functions (G31)

Measuring with "delete distance-to-go" (G31)
With "G31 X... Y... Z... F... ;" the measuring with "delete distance-to-go" is possible. If the measuring input of the 1st probe is
present during the linear interpolation, the linear interpolation is interrupted and the distance-to-go of the axes is deleted.
The program is continued with the next block.
Format
G31 X... Y... Z... F_;
G31: non-modal G function (active only in the block in which it is programmed)
PLC signal "measuring input = 1"
With the increasing edge of the measuring input 1, the current axis positions are stored in the axial system parameters or
$AA_MM[<Axis>] $AA_MW[<Axis>]. These parameters can be read in Siemens mode.
$AA_MW[X]
$AA_MW[Z]
$AA_MM[X]
$AA_MM[Z]
Note
If G31 is activated, while the measuring signal is still active, the alarm 21700 is output.
Program continuation after the measuring signal
If in the next block incremental axis positions are programmed, then these axis positions refer to the measuring point. That is,
the reference point for the incremental position is the axis position, at which the distance-to-go deletion is executed through
the measuring signal.
If the axis positions are programmed absolute in the next block, then the programmed positions are traversed.

Macro programs

Macros comprise of several part program blocks and are completed with M99. In principle, macros are subroutines, which
are called with G65 Pxx or G66 Pxx in the part program.
Macros called with G65 are non-modal. Macros called with G66 are modal and are deselected again with G67.
