Yokogawa is unmatched for our extreme commitment to asset reliability. At the heart of the Yokogawa systems is the unique "Pair and Spare" controller architecture, consisting of a redundant set of CPU modules, while each in turn contains two micro processors. These two continuously compare the output of the other, initiating a bump-less switchover if any mismatch is detected. Through this kind of reliability, Yokogawa CENTUM CS 3000 DCS has an availability of 99.99999% (seven 9s).
