摘　　要：针对于CAN总线成本低、数据传输距离远和传输速率快等特点。本文以DSP作为主节点,变频器为从节点,利用CAN应用层协议CANopen实现了变频器的远程控制。通过对CCS开发平台上程序的调试,完成了DSP和变频器的通信。同时介绍了变频器RCAN-01适配器参数配置、通信参数含义及通信程序。通过该模块用户可以由DSP向变频器发送控制命令或者获取一些实时参数值,进而对现场工作状态进行控制监测。CAN通信的实现对于现场总线控制具有较强的操作性和实用性。In view of CAN Bus with the low cost, long distance and fast rate of data transmission, this paper takes Digital Signal Processor（DSP） as the main station, and the converter is the Slave station, realizes the remote control of inverter by utilizing CAN application layer protocol CANopen. Communication is completed by debugging on CCS development platform between DSP and ABB driver. This paper also introduces parameter configuration, implication of communication parameters and communication program of RCAN-01 in ABB driver. Users can send control commands, or get the values of real time parameter from DSP to ABB driver by this way, and then control and monitor the field state. The implementation of CAN communication has strong operability and practicability for the field bus control.
