描述

AS-I网——传感器和执行器通信的国际标准，扫描时间5ms，传输媒体为未屏蔽的双绞线，线路长度为300m，最多为31个从站。

PROFIBUS——工业现场总线，用于车间级和现场级的国际标准，传输率最大12m/s，传输媒体为屏蔽双线电缆(最长9.6km)或光缆(最长90km)，最多可接127个从站。

工业以太网——用于区域和单元联网的国际标准，网络规模可达1024站1.5km(电气网络)或200km(光学网络)。

在这一网络体系中，尤其值得一提的是PROFIBUS现场总线，PROFIBUS是目前最成功的现场总线之一，已得到广泛地应用。它是不依赖生产厂家的、开放式的现场总线，各种各样的自动化设备均可通过同样的接口交换信息。为数众多的生产厂家提供了优质的PROFIBUS产品，用户可以自由地选择最合适的产品。PROFIBUS已经成为德国国家标准DIN19245和欧洲标准pr EN50170，并在世界拥有了最多的用户数量。
