摘要
介绍了CANopen协议;针对具有CANopen通信接口的变频器,和没有CANopen通信接口的西门子PLC,提出了通过网关实现两种设备之间的数据通信的方法,说明了方法以及要解决的关键问题;通过网关实现西门子PLC与具有CANopen通信接口变频器的通信,扩展了采用西门子PLC作为控制器的系统功能,提高了具有CANopen通信接口变频器控制的灵活性。
CANopen protocol was introduced.For inverter with CANopen communication interface and Simatic PLC without CANopen communication interface,a method that data communication between two devices was finished by gateway was proposed.The way and the leading problems were explained.Data communication between Simatic PLC and inverter with CANopen communication interface was finished by gataway,the system whose main control was Simatic PLC natural capacity was expanded.Flexibility of controlling inverter with CANopen communication interface was improved.
