Note
If a GEO axis (axis in the WCS) is programmed in a measuring block, the measured values
are stored for all current GEO axes.
13.3.2 Measurement results
Reading measurement results in the program
The results of the measuring command can be read in the part program via system
variables.
● System variable $AC_MEA[1]
Query measurement job status signal.
The variable is deleted at the beginning of a measurement. The variable is set as soon as
the probe fulfills the activation criterion (rising or falling edge). Execution of the
measurement job can thus be checked in the part program.
● System variable $AA_MM[axis]
Access to measured value in the machine coordinate system (MCS) Read in part
program. <axis> stands for the name of the measurement axis (X, Y, ...).
● System variable $AA_MW[axis]
Access to measured value in the workpiece coordinate system. Read in part program.
<axis> stands for the name of the measurement axis (X, Y, ...).

PLC service display
The measuring signal can be controlled via the "PLC status" menu in the "System → "PLC"
operating area:
IS "Probe 1 activated" (V2700 0001.0).
The current measuring status of the axis is shown by the IS "Measurement active"
(measuring block with this axis running).
