Product Introduction
The Yokogawa AFG84D Duplexed Field Control Station Migration Toolkit is a highly specialized system toolkit designed to facilitate the migration, configuration, and maintenance of duplexed field control stations (FCS) within Yokogawa’s CENTUM distributed control system (DCS) architecture. This toolkit provides a comprehensive solution for upgrading and transitioning from legacy control stations to modern, high-performance duplexed FCS platforms without disrupting plant operations.
The AFG84D toolkit ensures seamless migration of control logic, I/O configurations, and communication parameters, reducing engineering time and minimizing operational risks during system modernization. It supports advanced redundancy features that ensure continuous process control even in the event of hardware or communication failures.
Designed for reliability and compatibility, the AFG84D integrates effortlessly with Yokogawa’s CENTUM VP and CENTUM CS 3000 systems, ensuring data integrity, synchronization, and smooth system operation. Its flexible design allows for both partial and full system migrations, enabling process industries to adopt modern control technologies while retaining existing assets.
