Yokogawa CP471-00 S1 Field Control Unit Processor Module
The CP471-00 (Model: CP471-00) is a high-performance Field Control Unit (FCU) processor module engineered for the Yokogawa CENTUM VP and CS 3000 Distributed Control Systems (DCS). As a cornerstone of the S1 series hardware, this module is designed to execute complex regulatory control, advanced math functions, and sequence logic with deterministic timing.
Equipped with dual Ethernet bus ports for Vnet/IP communication, the CP471-00 (Part Number: CP471-00) facilitates seamless data exchange between the field control station and the human interface station (HIS). To ensure maximum process uptime, the module supports a 1:1 dual-redundant configuration. In this setup, the primary and backup processors operate in a synchronized "Pair & Spare" mode, allowing for an instantaneous, bumpless transfer of control if a hardware anomaly is detected. This robust architecture is essential for mission-critical applications in oil refining, chemical processing, and power generation.
