【Abstract】 The open CNC system’s real-time control sub-system is introduced in this paper. MCT8000F4 movement controller is used as the down location device of this system. The main contents include the integral structure and work principle of the system hardware, the software structure, the main function on the real-time control software and the interrupt server function. Because the key technologies have been applied in this system, such as collecting of real-time data, real-time monitoring, PLC controlling by software and programming skills of C language, this system realizes the real-time task control of the down location device.更多还原
