AFV10D-S41401 S2 | Yokogawa | CENTUM VP Field Control Unit

Product Description

Product Overview

YOKOGAWA AFV10D-S41401 S2 is a duplexed Field Control Unit (FCU) designed for the CENTUM VP Distributed Control System (DCS). It serves as the core field-level controller responsible for executing control logic, managing I/O communications, and maintaining system availability in mission-critical industrial environments.

This model adopts a fully redundant architecture, enabling continuous operation even in the event of hardware or communication failures. Its modular, rack-mountable design supports hot-swappable components, making it well suited for plants requiring uninterrupted operation and long-term system stability.

Functional Description

The AFV10D-S41401 S2 operates as a field control processor within the CENTUM VP architecture. It communicates with Field I/O (FIO) modules, executes control strategies, and exchanges real-time data over Yokogawa’s high-speed control network.

Key functional responsibilities include:

• Field-level control execution and I/O scanning

• Redundant communication with control networks and I/O subsystems

• Fault detection, diagnostics, and automatic failover

• Stable operation in high-availability system configurations
