1. The Need for Upgrade
Many CENTUM V and CENTUM-XL systems – Yokogawa DCSes – have been sold worldwide
since 1983 and 1988, respectively, and quite a few of these systems have been in operation for
more than ten years. However, along with the years that have passed since the systems were
introduced,theefciencyofplantoperationisdecreasingforthefollowingreasons:
• Systemfailureoccursmoreoftenduetoaging.
• Functionsbecomeobsolete.
• Systemmaintenancecostincreases.
Accordingly, there is increasing demand among customers for a low-cost system upgrade
method that can improve company competitiveness.
