Module processeur CENTUM VP Yokogawa CP471-00

Description

The Yokogawa CP471-00 is a high-performance Processor Module designed for deployment within CENTUM VP distributed control systems (DCS). This module mounts directly onto compatible field control units (FCUs) and serves as the primary processing core executing field control station functions. The CP471-00 supports high-availability operations, allowing dual-redundant configurations where two units are installed side-by-side in a duplexed field control unit to ensure continuous process automation and zero-downtime failover. It offers modern hardware architecture for executing complex logic, sequencing, and continuous control loop configurations required across industrial automation environments.

Features

• Dual-redundant configuration compatibility for uninterrupted control station failovers.
• Supports on-line replacement capabilities when deployed in active dual-redundant configurations.
• Directly replaces older CP461 modules via verified migration paths.
• Standard non-explosion protection basic design layout optimized for standard technical spaces.
• Native integration with ESB bus coupler module configurations for field peripheral connectivity.

Applications

• Distributed Control Systems (DCS) for continuous process industries.
• Petrochemical, chemical, and refining facility automation.
• Power plant control and infrastructure utility networks.
• Factory automation control loops and field-level sequence processing.

Installation Guidelines

• Module Mounting: The device must be mounted strictly on compatible field control units, including AFV30S, AFV30D, AFV40S, AFV40D, A2FV50S, A2FV50D, A2FV70S, and A2FV70D units according to regional regulations.
• Bus Coupling: Must be combined exclusively with style code S3 or later of the ESB bus coupler module EC401.
• CP461 Upgrades: While a pair of CP461 modules in an active dual-redundant layout can be on-line replaced with a pair of these modules, they cannot co-exist with a CP461 unit within the same dual-redundant configuration slot.
• Personnel Restrictions: Upgrading an existing field control installation from a CP461 to this module must be executed exclusively by a Yokogawa authorized service engineer.
• Replacement Constraints: Once a station has been updated, replacing the active module back with an older CP461 unit is strictly prohibited.

Compliance and Certifications

• System Standards: Complies with applicable standards as an integral part of field control units AFV30, AFV40, A2FV50, and A2FV700. Refer to CENTUM VP System Overview (GS 33J01A10-01EN) for general environmental compliance and specific standards.
