The Vision Master Calibration processing item may send three
parameters to the PLC: [Axis movement required for sampling],
[Origin return], and [Completion Timing of Calibration].
Each parameter is output after a reference of the calculation for
the Vision Master Calibration processing item is made.
With the PLC Master Calibration processing item, it is not neces-
sary to send data to the PLC, so Data Output processing items
are not necessary.
