c. Transmission and reception of cutting data
The CNC reads the change amount data at intervals of 16 ms. If
the read data is not 0, the CNC successively reads the item to
change and the change magnification data, then writes 0 to the
change amount to complete data reception. So, after checking that
the change amount data is 0, the PMC sets data of the item to
change and the change magnification (if the data is the same as the
previous data, the setting can be omitted), then writes the change
amount at the end.
