摘要:
A data input/output system for an application system (AS) which is provided with a processor (6) and a memory (8) therefor and is connected to numerical control equipment (NC) to take partial charge of its NC functions. The data input/output system makes it possible for the application system (AS) to input thereinto and output therefrom a program via an input/output interface (5) provided on the NC side, and to command the NC from the application system (AS) side. A receiving circuit (9 to 15) receives a program delivered from an NC processor (3) and a transmitting circuit (9 to 15) transmits to the NC processor (3) the program stored in the memory (8) of the application system. Data is input to and output from the application system (AS) via the input/output interface (5) provided in the numerical control equipment (NC).
