Abstract
Yokogawa’s 5 th generation of DCS (Distributed Control System) , CENTUM-XL will come to System EOS (End of Support) in September 2010. Maintenance support will have ended in 22 years since it was sold in 1988. Even Yokogawa has provided maintenance support service beyond EOS for customers who wish to continue to use our systems, this CENTUM-XL is hard to continue to support. In this paper, we would like to summarize the situation and let customers understand it.
Also, to get customer’s consensus and cooperation, we explain the tasks to solve and some solutions for them for longer usage of our system.
