Distributed Cement Plant Control - The Intelligent Approach

Rapidly evolving technology has made a broad variety of control system solutions available to industry. Most recently, microprocessors have formed the leading edge of the technology growth. The capability inherent in the present generation microprocessors will not only change the appearance of control plant-equipment, it will in fact change the methods for implementing wide control. The use of microprocessors in a distributed control mode is discussed. The system configuration consists of a central processing unit, intelligent operator's panel, and intelligent distributed field control multiplexers. Each device is described from an operational viewpoint. Special features are presented relative to the system and its applicability for control of a cement plant. In conclusion, intelligent distributed control offer the way to improved control, greater reliability, and lower installed costs.
