摘　　要：E-Link是一种廉价、方便、小巧的串口以太网接口模块。随着Internet的蓬勃发展,人们在各个地点都可通过互联网来交换信息。各种智能仪器和设备都应具备入网的功能,通过E-link数据传输器,只需拥有串行口就可以使现有设备方便地接入网络,不再需要PC+网卡+设备接口卡,直接通过E-Link就可方便地接入以太网。利用廉价的"E-Link网络数据传输器",利用互联网取代现场总线,使原现场总线的分布式控制系统方便地转换成基于以太网的分布式控制系统。E-Link is a kind of low-price, convenient, small and exquisite bunches of Ethemet interface module. As flourishing development of Intemet, people can exchange information through Intemet anywhere.Various kinds of intelligent instruments and equipment should possess function of network access.Only using a serial port,the existing equipment can be obtained access to network easily through E-Link data transmission.In this way the equipment no longer needs the PC ＋ network card ＋ equipment interface card,and can be inserted into Ethemet conveniently through E-Link directly.The DCS based on original field bus can be converted conveniently to DCS based on Ethemet web by using ＂ E-Link network data transmission device＂ and replacing of field bus by intemet.

关 键 词：以太网 E—link 串行接口 网络 数据传输器
