The CP461-10 (Model: CP461-10) is a high-availability control processor module engineered for Yokogawa’s CENTUM VP and CS 3000 Distributed Control Systems (DCS). Specifically designed for use within AFV300 and AFV400 Field Control Units, the CP461-10 (Style S1) serves as the central processing core, executing regulatory control functions and managing complex process automation strategies.
To ensure maximum plant uptime, the CP461-10 (Part Number: CP461-10) supports a 1:1 dual-redundant configuration. In this setup, two modules operate in synchronization; if the primary unit detects an internal fault, the backup module assumes control instantaneously via a "bumpless" transfer. This deterministic execution and fault-tolerant architecture make it a critical component for large-scale operations in power generation, chemical processing, and oil refining.
The CP461-10 (Model: CP461-10) is optimized for high-speed Vnet/IP communication and real-time control logic execution.
