摘要
本文讨论CANopen总线的原理,并在结合施耐德M340系列PLC基础上采用CANopen总线对施奈德ATV71变频器的实时控制,给出了该控制系统的详细硬件配置,软件程序,提供了基于CANopen总线的控制方案,实际结果表明控制系统运行稳定,效果良好。
The principle of the canopen bus is introduced in the paper, and ATV71 converter is controlled used canopen bus by M340 PLC. The control system＇ full hardware constructions is given, and software programmer and control design based on CANopen bus are given in the paper. The results show that the control system is stability and have a good performance.
