What the CENTUM CS 3000 Solution ContributedNot a single wire touchedYokogawa offered to migrate Nisseki Chemical to the world renowned CENTUM CS 3000 without touching a single wire in the field. This migration solution to a state-of-the-art control system was low cost, low risk, and cost effective. Due to the need for a rapid turnaround in this project, the cable switching was done within one day. No field re-wiring was required thanks to the use of a fully compatible field terminal assembly (FTA) board.A simple and cost-effective migration solutionWith Yokogawa’s migration solution, Nisseki Chemical’s legacy controllers and process interface units were replaced with CS 3000 I/O and processors utilizing special marshalling panels and adapter cables that connected to the existing terminal panels. Auto conversion of user applications was not necessary since the applications in use were simple and easily understood.Dramatic Reduction in Process DowntimeNone of the existing field wiring was disturbed and no new cabinets needed to be wired, achieving a dramatic reduction in process downtime. In fact, thanks to the compact design and high density of the CS 3000 cards, the number of cabinets required was reduced and valuable space was freed up for other uses.ResultsThe actual replacement of Nisseki Chemical’s legacy system took just one day and the entire project was completed with just five months of preparation. This project achieved the following results:Faster commissioningThe elimination of field rewiring and the resulting rapid switchover from the legacy system to the CENTUM CS 3000 meant that Nisseki Chemical plant could minimize the opportunity cost incurred by having production lines shut down. Productivity Improvement and Cost Effectiveness AchievementThe state of the art capabilities and high reliability of the CENTUM CS 3000 control system has reduced operating costs and improved uptime at the Nisseki Chemicals plant.Customer’s SatisfactionNisseki Chemicals has been very impressed at the speed and cost-effectiveness of the switchover from its legacy system to the CENTUM CS 3000 and is more than satisfied with the system’s performance and functionality. They are pleased to have made the right choice in going with a Yokogawa migration solution.Central control roomSuccess Story Collection52Nisseki Chemical Texas Inc. / USA
