Case Study - ABB (Bailey)
Yokogawa developed special cables to directly connect ABB INFI 90 termination units to the Yokogawa CENTUM CS 3000 input and output modules.

•Minimization of cutover time & risk

The field wiring to INFI 90 I/O termination units and dip shunt settings could be used as is, eliminating the need to disconnect and reconnect field cabling and minimizing cutover time.

As changes to the field wiring and I/O terminations were not necessary, loop checking was eliminated. Furthermore, all control logic could be debugged in advance using a standard software tool, the CENTUM virtual test function. In so doing, process downtime and test runs could be minimized.

•Minimization of the construction costs & production losses

The field wiring and I/O terminations of the existing system remained intact, preserving the user’s investment and minimizing process downtime during the transition from the ABB
INFI 90 system to the Yokogawa CENTUM CS 3000 control system. Migrating from an existing control system to the latest CENTUM CS 3000 system presented an opportunity to upgrade to the latest information technologies, implement new automation strategies, and introduce new business packages.
