摘要
针对现场总线接入以太网时,实时性要求较高的问题,采用隧道技术,简化了接入路由器的结构,缩短路由转发所需时间,从而使现场总线通过以太网进行互联成为可能。
In view that it must satisfy real-time request when Fieldbus network is connected with Ethernet, this paper adopts the tunneling method to simplify the router's structure. With this method ,the time for thansmitting is reduced and it is possible for devices in different Fieldbus to communicate through Ethernet.
