摘要
首先介绍了现场总线标准在经过长达１５年争论之后，终于形成一个由多部分组成的ＩＥＣ ６１１５８国际标准。随后较全面地论述了该标准所包括的八种类型现场总线的背景、特点、协议和结构。在此基础上，作者认为：当前的现场总线之争是国际上各大公司为瓜分市场而展开的保卫各自“庄园”的争斗，它已阻碍工业自动化领域网络技术的发展和产品的更新换代，并预见Ｅｔｈｅｒｎｅｔ／ＩＰ技术将会十分迅速地进入工业控制系统的各级网络。
The International Standard of IEC 61158 which is composed of several parts is introduced. The standard of field bus is generated after contention for nearly 15 years. The background, features, protocol and structure of eight kinds of field buses are described comprehensively. On this basis, the author stated that the contention on the field bus shows the competition between all the companies in this field for getting bigger market share. Thus it hinders the development of the networking technology in process automation area and the upgrade of products. It is forecasted that the Ethernet IP technology will enter each layer of the network in process control area rapidly.
