Online DCS migration system (IST-203)

The IST-203 facilitates a DCS migration during active process conditions to eliminate downtime, also known as a online DCS migration. The tool takes over and simulates 0(4)-20 mA loops allowing the user to perform an online control system migration without any disturbance of the process, while increasing efficiency, control and safety.


Efficient and safe DCS migration process

Many distributed control systems in process plants are reaching the end of their product lifetime. With today’s requirements in the field of safety, efficiency and control, a control system migration to a modern system is in many cases inevitable.

A couple of factors are of great importance to plant managers and DCS migration managers during a migration project. They prefer a reliable and solid migration solution for all critical loops to improve efficiency and safety. They are also looking for a quick and easy process because in the case of a DCS migration; downtime cost a lot of money!
