Innovating distributed control system -The past and the future-

Distributed Control System (DCS) appears on the market as a substitution of a panel instrument or a distributed system of Direct Digital Controller. At the beginning stage DCS was growing based on the severe evaluation and the feedback from the customers of all process industries and finally DCS established the firm position as one of the indispensable equipments in the process industry. During this period the technical development of computers was remarkable and our office environment changed drastically however the basic architecture of DCS has not changed. This proves that DCS abstracted the necessary functions highly and integrated them from the beginning. Currently the production activity of the company regarded as one system. All the function in the company evaluated as the contribution of the profits of the company as a whole. Naturally, the expected role for DCS exceeds a limit as merely a distributed control system and it should be innovated as an important platform to operate the plant.
