The functional test for the probe is conducted via an NC program.
The measuring signal can be controlled after the end of the program via the
diagnostics menu “PLC status”.

Data block Signal(s) from axis/spindle (drive_PLC)
Edge evaluation: no Signal(s) updated: cyclically Signal(s) valid as of SW: 1.1
Signal state 1 or edge
change 0 - - ->1
Probe 1 or 2 is activated.
Signal state 0 or edge
change 1 - - -> 0
Probe 1 or 2 is not activated.

Note The above mentioned signal states correspond to the default setting (non-deflected 0 V;
deflected 24 V). Otherwise, the measurement input No. must be entered as a negative
number.
