Abstract: CAN (Controller Area Network) is one of popular field bus and a new kind of network based on micro control unit. The paper introduces the CAN node based on the industrial instruments controlling system and node design of hardware and software. The paper design different CAN nodes which can communicate each other in several modes. The node can be applied in control network which is composed of many special sites or industrial workshops. The system can be monitored through personal computer which connected the CAN bus through special CAN device.
