横河公司于1988年发表了CENTUM-XL系统,1989年又发表了μXL系统。每个新系统的出现,都给分散型控制系统带来新意,使分散型控制大跨一步。本文重点介绍CEN-TUM-XL系统和μXL系统。一、开发思想 CENTUM-XL是以1975年问世的分散型控制系统CENTUM为基础,运用了最先进的过程控制技术、电子技术、通信技术、人-机接口技术而完成的分散型控制系统。在工厂中,不仅要推进过程控制的自动化,而且要引进和市场需求直接相连的多品种小批量的生产方式,进一步使工厂管理计算机和其他控制系统构成密切的通信网络。CENTUM-XL是能适应这样的要求,面向90年代的新一代控制系统的杰出产品,特别是对于炼油、
Yokogawa issued the CENTUM-XL system in 1988 and the μXL system in 1989. The advent of each new system brings new ideas to decentralized control systems and enables decentralized control over a large span. This article focuses on the CEN-TUM-XL system and the μXL system. I. Development Thought CENTUM-XL is a decentralized control system based on CENTUM, a decentralized control system that came out in 1975. It utilizes the most advanced process control technology, electronic technology, communication technology and human-machine interface technology. In the factory, not only should automation of process control be promoted, but also the introduction of multi-species and small-batch production methods that are directly linked to market needs further enables the plant management computer and other control systems to form a close communication network. CENTUM-XL is an outstanding product that can meet such requirements and is oriented to a new generation of control system in the 90s, especially for refining,
