近年来，分散控制系统与工业色谱仪在过程控制中的应用已越来越广泛，逐渐成为大中型石油化工装置的主要仪表设备。两者如何接口是自控设计工程师们所关注的问题。该文就洞庭氮肥厂合成氨装置的6750工业色谱仪-CENTUM分散控制系统接口技术的有关问题作一介绍。
In recent years, decentralized control systems and industrial chromatographs have become more and more widely used in process control and have gradually become the main instrument and equipment of large and medium-sized petrochemical plants. How to interface between the two is a concern of design engineers. This paper introduces the related problems of 6750 Industrial Chromatograph-Centrum Distributed Control System Interface Technology of ammonia plant in Dongting Nitrogen Plant.
