Centum: 30 years of excellence

Supplier News

YOKOGAWA Electric Corporation has launched its Centum 30th Anniversary website - at: www.yokogawa.com/iab/centum30th.

In June this year, Yokogawa commemorated the 30th anniversary of the Centum series production control system, a core product of its industrial automation (IA) business.

Yokogawa released the world’s first distributed control system (DCS), the initial version of Centum, in June 1975. This version employed multiple microprocessors, each of which was assigned to different areas of the plant for effective risk distribution.

By enabling plant operation and monitoring to be performed via CRTs, Centum helped operators work far more efficiently while reducing both labour costs and instrumentation room space requirements. Before the DCS was employed, plant control and monitoring was done via analogue panel instruments. As a control and monitoring instrument had to be mounted on the display console for each control loop to facilitate testing, measurement and the issuance of commands in response to test and measurement results, such consoles took up a lot of space and required many operators.

The total number of Centum systems installed for customers worldwide since 1975 has exceeded 10,000.

The new website includes an interactive flash movie that looks back at 30 years of performance, a web-exclusive free trial of Yokogawa’s latest alarm management and property estimation solutions, and a section entitled “The Future of Performance”. This provides highlights relating to the fact that, as a key enabler of the VigilantPlant vision, Centum is evolving into a collaborative process automation system.
