摘要
随着网络技术的高速发展,以太网通信技术在工业控制领域获得了飞速发展,并渗透到工业自动化系统的底层网络,与现场总线技术展开竞争。本文探讨了一种采用以太网实现控制系统通信的方法,并成功地实现了和利时公司CPU24x系列PLC和西门子公司S7-300/400系列PLC的相互通信。
With the high development of network technology, Ethernet communication technology got a very quickly develop speed in the industrial control area. It has penetrated into the network bottom of industrial automation system, and competed with the fieldbua technology. In this paper a kind of method with Ethernet that realized the communication of control system was discussed. And it realized the interconnected communication successfully between CPU24x series PLC of HOLLYSYS Company and S7-300/400 series PLC of SIEMENS Company.
