Further Information
Measuring job status
If an evaluation of whether or not the probe has been triggered is required in the program,
status variable $AC_MEA[n] (n= number of the measuring probe) can be checked:
Value
0
1
Note
If the program is deflected in the program, the variable is set to 1. At the start of a
measurement block, the variable is automatically set to the initial state of the probe.
Reading measured values
The positions of all traversing path and positioning axes of the block are acquired (maximum
number of axes depending on the control configuration). In the case of MEAS, the motion is
decelerated in a defined fashion following the triggering of the probe.
Note
If a GEO axis is programmed in a measurement block, the measured values are stored for all
current GEO axes.
If an axis participating in a transformation is programmed in a measurement block, the
measured values for all axes participating in this transformation are recorded.
