Programming example
Continuous measurement in mode 1
(evaluation in chronological sequence)
Measurement of up to 100 measured values
...
N110 DEF REAL MEASVALUE[100]
N120 DEF INT INDEX = 0
N130 MEAC[X] = (1,1,-1) G01 X1000 F100
Measure in mode 1 with active
measuring system, store measured
values under $AC_FIFO1, wait for
measuring signal with falling edge from
probe 1 on travel path to X = 1000.
N135 STOPRE
N140 MEAC[X] = (0)
Terminate measurement when axis
position is reached.
N150 R1 = $AC_FIFO1[4]
Store number of accumulated measured
values in parameter R1.
N160 FOR INDEX = 0 TO R1-1
N170 MEASVALUE[INDEX] = $AC_FIFO1[0]
Read measured values from $AC_FIFO1
and store.
N180 ENDFOR
