1. Digital motherboard: used for core control, calculation, storage, servo control, etc. The new motherboard integrates PLC control system functions.

2. PLC board: used for peripheral action control. The PLC board of the new system is integrated with the CNC main board.

3. I/O board: The early I/O board was used for switching signals between the NC system and the external. The I/O board mainly integrates display interface, keyboard interface, handwheel interface, operation panel interface and RS232 interface.

4. MMC board: man-machine interface board. Computerized board with CRT, standard keyboard, floppy drive, mouse, memory card and serial and parallel interfaces.

5. CRT interface board: used for display interface. In the new system, the CRT interface is integrated with the I/O board.
