Application of CANopen protocol in industrial control system

Kaiyuan Meng

Abstract

CANopen,as a well-known application protocol of CANbus,is widely applied in field bus control system.Based on the analysis of the characteristics of CANopen protocol,the communication control module and the I/O control module are developed using AT91SAM7X256 microprocessor according to the actual situation in oilfields,and an oilfield network communication system based on CANopen protocol is designed,which improves greatly the efficiency and reliability of oilfield communication.
