Design of Machine Operating Panel Based on CAN Bus for the PC-Based CNC System

Machine operating panel is an important component of controlling machine and the human-computer interaction. As CAN bus has the remote and stable transmission characteristic, the remote IO board is designed. A design of machine operating panel based on CAN bus for the PC-based CNC system is introduced, including the overall architecture design and software design method. This paper focuses on the remote IO board, as well as the practical application in the CNC system of TDNC-H8.
