Function
Several probes and several measuring systems can be used for the axial measuring.
The MEASA or MEAWA command can be used to acquire up to four measures values for the
respective programmed axis; these are then saved in system variables in accordance with
the trigger event.
Continuous measuring tasks can be executed with the MEAC command. In this case, the
measurement results are stored in FIFO variables. The maximum number of measured
values per measurement is also four with MEAC.
