Reconfigurable controller for monitoring and controlling environmental conditions

摘要

A highly distributed direct digital process control system for use in controlling a fully distributed process includes at least one device controller independently monitoring and controlling a plurality of external devices for performing a complete process. One or more data concentrator units are connected to the controllers for collecting information from each controller as well as directing updated control information to specific controllers. A central information processing system is connected to the data concentrator for displaying information received from the data concentrator. The central information processing system is capable of updating control information used by specific controllers.
