基于DSP的CANopen通讯协议的实现

CANopen是一种开放的应用层协议,其应用可以进一步提高系统的可靠性、通讯效率及灵活性,而且可以使产品具有很好的兼容性。本文采用CANopen通讯协议实现了CAN总线DSP系统与上位机CAN卡之间的通讯,并通过测试实验验证了信息传递的可靠性,保证了全数字网络化伺服驱动系统中对电机控制的准确性和实时性。

CANopen protocol is an open application protocol, the use of it enhances the agility and efficiency in communication andimproves interoperability and interchangeability among products from different manufacturers. This paper describes its implementationon the communication system between CAN- bus DSP system and CAN card in PC system. The reliability of communication is veri-fied by testing experiment and the results illustrate that this solution can ensure the veracity and real time feature of motion controlsystem.
