摘要
本文从工业控制网络的发展要求以及以太网自身特点出发 ,具体论述了将以太网应用于工业控制网络所存在的三个主要问题 ,包括传输的不确定性、以太网的可靠性问题以及缺乏统一的应用层协议 .总结了上述问题的现有解决方法 ,其中比较详细地介绍了通过改进传输协议提高确定性的方法和现有的两种开放的应用层协议 .在文章的最后进一步阐述了对于工业以太网当前主要研究方向的个人观点 .
According to the development demand of industrial control network and the characteristics of Ethernet, this paper summarizes three main problems of industrial Ethernet, including the transmission indeterminacy, the reliability of Ethernet and the lack of unified application layer protocol. Furthermore, the authors summarize the solutions for the above problems. The methods to improve determination by adapting transmission protocol and two current open application layer protocols are discussed in detail. The individual viewpoint in the research direction of industrial Ethernet is aso presented.
