SYSTEM FOR SHARING DATA BETWEEN MANAGEMENT PC AND CONTROL APPARATUS IN MONITORING-CONTROL SYSTEM

摘要

A data sharing system between a computer and a control device in a monitoring control system in accordance with the present invention can allow data sharing between a field and a central control tower by automatically performing a differential transmission processing depending on whether the status value of data in field devices has changed, and dualizing the object for transmission so that the transmission speed and traffic efficiency could be optimized for a field condition.
