摘要
介绍了分散控制系统中一种显著改善数据传输性能的组网方式。针对当前DCS应用出现的网络通信问题与不足,说明了在DCS应用中增加第三条专用网络的技术与思路,使DCS中工业以太网的功能得到更进一步的增强,从而更好地满足大中型规模的DCS工程项目的需求。
The effective method of constructing network in distributed control system is introduced.The method prominently improves the performance of data transmission.Aiming at problems and deficiencies of network communication in current applications of DCS, the technique and idea of adding the third dedicated network in application of DCS are illustrated. Those enhance the function of industrial Ethernet in DCS, thus it can meet the requirements of the medium-or-large-scale DCS projects.
