Open Network of Control Systems, which connects controller level equipments with HMI(Human machine interface), is expanding its application as a standard Network of Control Systems depending to region and usage, since its advantage is acknowledged by active promotion, though Open Network of Control System was proprietary to equipment manufacturer for a long time. @Since the level of requirements such as high speed, high reliability and large capacity, etc. is severe in metal industry production system, the investigation of real situation and the examination of the measure for the Open Network of Control Systems application are urgent tasks. Technical Committee of Metal Industry Division of the Institute of Electrical Engineers Japan organized "Investigation Committee for Open Network of Control Systems Application in Metal Industry Production System". It made investigation of the actual conditions, extraction of the subjects, and examination of the requirements for Open Network of Control Systems application in typical iron and steel production facilities, for two years or more from JUNE 2006. Basic investigation results concerning Open Network of Control Systems application in metal industry production system were obtained through the committee activities. In this report, the investigation of Open Network of Control Systems application status, the extraction of subjects in application, the study of standardization trend, and the measure and its subjects for application expansion were brought together, and additionally its direction in the future was considered. |
