Abstract
A CNC apparatus (10), wherein a PC circuit (300) for sequence control of a peripheral device is provided in addition to a PC circuit (200) for sequence control of a machine (60) to be numerical controlled. The sequence programs executed by the respective PC circuits are made capable of independently inputting to and outputting from EEPROMs (240, 340) and also made capable of independently editing and diagnosing. Further, signal transmission and reception between the PC circuits (200 and 300) so that both the sequence programs can be executed coordinately with each other.
