YOKOGAWA CP451‑10 S2 Product Description

YOKOGAWA CP451‑10 S2 is a high-performance processor module for Yokogawa CENTUM VP DCS control stations (AFV10S / AFV10D). It serves as the core CPU unit responsible for executing continuous control logic, sequence programs, alarm management, data acquisition and inter-module communication via Vnet/IP. This S2 revision module delivers deterministic real-time processing for critical industrial processes, supporting redundant configuration to maximize system uptime and is widely used as spare replacement hardware for existing CENTUM VP systems.
