----工业以太网是基于ieee 802.3 (ethernet)的强大的区域和单元网络。利用工业以太网，simaticnet提供了一个无缝集成到新的多媒体世界的途径。----企业内部互联网(intranet)，外部互联网(extranet)，以及国际互联网(internet)提供的广泛应用不但已经进入今天的办公室领域，而且还可以应用于生产和过程自动化。继10m波特率以太网成功运行之后，具有交换功能，全双工和自适应的100m波特率快速以太网(fastethernet，符合ieee802.3u的标准)也已成功运行多年。采用何种性能的以太网取决于用户的需要。通用的兼容性允许用户无缝升级到新技术。为用户带来的利益市场占有率高达80%，以太网毫无疑问是当今lan(局域网)领域中首屈一指的网络。以太网优越的性能，为您的应用带来巨大的利益：通过简单的连接方式快速装配。通过不断的开发提供了持续的兼容性，因而保证了投资的安全。通过交换技术提供实际上没有限制的通讯性能。各种各样联网应用，例如办公室环境和生产应用环境的联网。通过接入wan(广域网)可实现公司之间的通讯，例如，isdn 或internet 的接入。simaticnet基于经过现场应用验证的技术,simaticnet已供应多于400,000个节点，遍布世界各地，用于严酷的工业环境，包括有高强度电磁干扰的区域。工业以太网络的构成一个典型的工业以太网络环境，有以下三类网络器件：网络部件连接部件：fc 快速连接插座els(工业以太网电气交换机)esm(工业以太网电气交换机)sm(工业以太网光纤交换机)mc tp11(工业以太网光纤电气转换模块)通信介质：普通双绞线，工业屏蔽双绞线和光纤simatic plc控制器上的工业以太网通讯外理器。用于将simatic plc连接到工业以太网。pg/pc 上的工业以太网通讯外理器。用于将pg/pc连接到工业以太网。工业以太网重要性能 为了应用于严酷的工业环境，确保工业应用的安全可靠，simatic net 为以太网技术补充了不少重要的性能：工业以太网技术上与ieee802.3/802.3u兼容，使用iso和tcp/ip 通讯协议10/100m 自适应传输速率冗余24vdc 供电简单的机柜导轨安装方便的构成星型、线型和环型拓扑结构高速冗余的安全网络，最大网络重构时间为0.3 秒用于严酷环境的网络元件，通过emc 测试通过带有rj45
