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
Byte
DBB0
DBB1
To test the switching behavior and the measured value transfer, use an NC test program with,
for example, the following NC commands:
MEAS
$AC_MEA[n]
$AA_MW[axis name]
$AA_MM[axis name]
