摘　　要：将CANopen通信子协议DS301作为CAN网络实现基础,设计了一种基于DSP TMS320F28335的CANopen通信协议从站。构造CAN通信的主从节点总线网络硬件平台,并按照协议的规定完成从节点软件编写任务,实现该从站与主站PLC通信数据,在此平台上测试数据传输对象的基本功能。结果验证了主从节点之间数据收发的有效性,实现了CANopen协议的基本要求。Regarding CANopen communication sub protocol DS301 as the foundation of CAN implementation network,a CANopen communication protocol based on DSP TMS320F28335 is designed. The hardware platforms were constructed between the master and slave node. Complete software development tasks in accordance with CANopen Protocol,implementing the PLC communications data from the station and the main station,testing a variety of basic communication object functionality. Results demonstrate the effectiveness of data to achieve the basic requirements of the CANopen Protocol.
