基于Ethernet的全开放工业控制网络

摘要

本文从信息发展的进程出发，总结了现场总线在发展中存在的问题，阐述了以太网进军工业自动化领域的必然性，说明了以太网将最终连接大多数的传感器和执行器，并由此形成一种基于以太网的全开放的扁平化工业控制网络结构。%Acccording to the process of information development,this paper summarizes the current problems existing in fieldbuses, and describes the inevitability that can promote Ethernet to march towards the industrial automatic control field. Ethernet is sure to be albe to connect itself with all transducers and actuators at working fields so as to form an open and complanate network architecture for industrial control.
