Yokogawa CP471-00 | Vnet/IP Field Control Unit Processor Module

Product Overview

The CP471-00 (Model: CP471-00) is a high-performance Field Control Unit (FCU) processor designed for the Yokogawa CENTUM VP and CS 3000 Distributed Control Systems (DCS). As a central processing component within the S1 hardware series, this module is engineered to execute sophisticated regulatory control, complex arithmetic functions, and sequential logic with microsecond-level determinism.

A standout feature of the CP471-00 is its integrated Vnet/IP capability via dual-redundant Ethernet ports. This allows for high-bandwidth, reliable data exchange between Field Control Stations and Operator Human Interface Stations (HIS). The module utilizes a "Pair & Spare" hardware architecture, where two processors run simultaneously to provide a bumpless, instantaneous transfer of control should a hardware error occur. This ensures 99.9999% availability for mission-critical operations in oil refining, chemical processing, and power generation.
