Testing the probe function
You can test the switching function of the probe by manually deflecting it and checking the
following PLC interface signals:
DB2700 General signals from the NC
NC -> PLC interface

To test the switching behavior and the measured value transfer, use an NC test program with,
for example, the following NC commands:
MEAS Measurement with deletion of distance-to-go
$AC_MEA[n] Check the switching operation, n = measurement input number
$AA_MW[axis name] Measured value of the axes in workpiece coordinates
$AA_MM[axis name] Measured value of the axes in machine coordinates
