摘　　要：为了更适合在工业控制通信系统中应用,根据设备(通信口)与协议解析分层的设计原则,采用Modbus协议转换模块,使标准RS485接口与上、下位机同时进行串行通信,网络信息透明传输,手动设置波特率,设计了一个基于W77E58单片机的modbus通信适配器,该适配器具有较强的可组态性和可扩展性。According to the design principle of equipment （communication port） and protocol stratification analysis, it designs a MODBUS communication adapter based on W77E58. The paper employs the protocol conversion module Modbus, enabling the standard port RS485 to conduct serial communication with the upper and lower computer, which results in the transparent transfer of network information and manual adjustment of the baud rate. The adapter can be better applied to industrial control communication system, possessing a strong configurability and scalability.
