The Yokogawa CP471-00 S1 serves as the high-performance computational core for Field Control Stations (FCS) within the CENTUM VP and CENTUM CS 3000 R3 (and later) environments. This Communication Processor Unit (CPU) executes complex regulatory control strategies, sequential logic, and advanced batch applications. We provide this module as 100% Brand New and Original, ensuring high-availability performance for continuous process industries such as oil and gas refining, power generation, and chemical processing.

Optimized Computational Throughput: The 64-bit RISC architecture accelerates the execution of thousands of function blocks simultaneously. This allows the DCS to handle massive I/O counts without compromising scan-rate consistency.
Deterministic Network Management: By utilizing Vnet/IP, the CP471-00 S1 ensures secure and deterministic data exchange between the field control unit and engineering stations. This prevents network jitter from affecting time-sensitive control loops.
Zero-Downtime Maintenance: The module supports full hot-swap capability in duplex (redundant) configurations. Engineers can replace a failed unit while the plant remains operational, eliminating the need for costly scheduled shutdowns for hardware maintenance.
Long-Term Asset Protection: This processor offers a direct replacement path for older CP461 modules. This compatibility allows facility managers to upgrade the processing power of existing AFV30D/AFV40D units without a full system overhaul.
Ruggedized for Process Stability: Forced air cooling and industrial-grade components allow the module to operate reliably in control rooms experiencing temperatures up to 55°C, ensuring stability in non-ideal environmental conditions.
Can the CP471-00 S1 replace an existing CP461 module?
Yes, in many Field Control Units (FCS) such as the AFV30D or AFV40D, the CP471-00 S1 serves as a high-performance upgrade or replacement for the CP461. Always confirm your current software revision supports the CP471 hardware.
What precautions should I take during installation?
Ensure the Field Control Unit (FCU) power supply remains stable and that you seat the module firmly into the backplane. In a redundant setup, wait for the "Standby" LED to indicate synchronization before performing any further hardware changes.
Does this module require a separate battery?
The CP471-00 S1 utilizes 512 MB of onboard Flash memory for non-volatile storage of the operating system and control parameters, reducing dependence on traditional battery-backed RAM for data retention.
Is this a genuine Yokogawa Japan product?
