摘要
论述了目前应用很广的EtherNet／IP协议，并选择具有RS485接口的断路器为应用对象，设计了一种外挂式的通信协议转换器，给出了基于AT91SAM7X256的软硬件设计方法。实际测试表明该转换器可使主控机与现场断路器之间正常通信，符合低压电器的网络化的发展趋势。
EtherNet/IP protocol applied very broad is present in this article, and choose a circuit breaker which has RS485 interface as the object,the communication protocol converter which used the outside of the circuit breaker is designed,and give a design method of software and hardware of communication protocol converter based on AT91SAM7X256.The communication is normal between the main control machine and the circuit breaker through the actual test, meanwhile the design conforms to low-voltage electrical equipment＇s network trend of development.
