Aiming to the characteristics existing in the laser cutting production line, such as many I/ O points, large amount of information exchange, high requirements for real-time and the reliability, the application of CAN (Control Area Networks) bus in high-power laser cutting production line had been researched. The upper computer used PLC1131-3 and VC++software for developing application,all the communication module of the lower machine utilized STM32 processor as the main chip,including soft and hardware design, the upper computer and all the communication module of the lower machine achieved communications with each other via the CAN bus. Practical application in a high-power fiber laser cutting CNC system shows that the communications is stable and reliable with strong real-time and anti-jamming capability,and this application has good scalability in the field of industrial process automation.
