Description

1. Product Title

YOKOGAWA CP471-00 – CENTUM VP Processor Module

2. Product Overview

The YOKOGAWA CP471-00 is a high-performance 32-bit processor module designed specifically for the CENTUM VP Distributed Control System (DCS). It serves as the primary intelligence unit within Field Control Units (FCU), such as the AFV30 and AFV40 series. The module is responsible for executing real-time control logic, managing process data, and ensuring high-speed communication across the Vnet/IP control network.

In mission-critical industrial environments, the CP471-00 addresses the need for extreme reliability and system longevity. It provides a significant performance boost over legacy processors like the CP461, offering larger memory capacity and faster execution cycles. By supporting dual-redundant configurations, the CP471-00 ensures that process control remains uninterrupted even in the event of a hardware fault, making it a cornerstone for safety and efficiency in complex industrial plants.
