摘　　要：介绍了modbus协议,并以EasyARM2131为硬件平台,在uCOS_Ⅱ系统上按照网络分层思想逐层实现RTU传输模式下modbus从站协议栈的过程。通过与组态王、力控组态软件通信连接,表明该实现实时性好、性能稳定。The modbus protocol is introduced briefly and how to implement its slaves protocol in RTU mode based on EasyARM2131 and the embedded real-time kernel uCOS_II with the thoughts of network layers is explained in detail. According to the result of connection with KingView and ForceControl software, it shows that the implementation has good real-time and stable performance.
