摘　　要：提出了一种用AVR单片机及硬件协议栈芯片W 3100A实现MODBUS设备接入以太网的方法,基于此嵌入式WEB网关,建立了一个MODBUS/TCP监控网络,并给出了硬件设计思路,最后重点介绍了MODBUS/TCP网关软件的实现方法。在实际工程应用中体现了其灵活性、通用性、低成本等优点。Based on AVR MCU and embedded TCP/IP hardware protocol stack chip W3100A, the design of modbus gateway for linking to Ethernet is introduced. With the function of embedded web, the gateway is used to built a Modbus/TCP supervisal and control system. A hardware design is provided. At last, the method of software design is introduced. Meanwhile, its many advantages such as flexibility and commonality, low cost to be proven by practical application are introduced.
