Yokogawa developed marshaling boards/cards and special cables so that the CENTUM
CS 3000 could be connected to Honeywell TDC2000/3000 components without having to modify the existing field wiring.

• Minimization of construction costs

Field wiring and I/O terminals (FTAs) of the existing system remained intact, preserving the customer’s investment.

• Reduction of process downtime

With no need for changes to the field wiring and I/O terminals (FTAs), the need for loop checking was eliminated. Furthermore, all control logic could be debugged in advance by using a standard software tool, the CENTUM virtual test function. Therefore, downtime and test runs could be kept to a minimum.

Migrating from an existing control system to the latest CENTUM CS 3000 system presents an opportunity to achieve operational excellence, introduce new information technology, pursue new automation strategies, and go in a new business direction.
