Distillation system DCS control system design
Abstract: Application integration technology, design a distributed control system, the completion of the rectification process control system. DCS (Distributed Control System, DCS) microprocessor-based, using decentralized control, centralized display operation, taking into account the pide and autonomy and overall coordination of the design principles of a new generation of instrument control system. It is a process by the process control level and composition of the monitoring level communications network as a link to a multi-level computer systems, integrated computer (Computer), communication (Communication), Display (CRT) and control (Control) et 4C technology, which the basic idea is decentralized control, centralized operation, hierarchical management, flexible configuration, easy configuration. This design requires the application of system integration technology, the choice of distributed control system design, system test system to complete the rectification process control system.
