YOKOGAWA CP471-00 | Processor Module for CENTUM VP Field Control Units
CP471-00
The YOKOGAWA CP471-00 is a high-performance processor module designed for CENTUM VP Field Control Stations (AFV30, AFV40, A2FV50, and A2FV700). It delivers reliable execution of control functions with support for dual-redundant configurations to ensure continuous and stable industrial operations.
High-Performance Processing for CENTUM VP DCS Systems
The YOKOGAWA CP471-00 Processor Module is designed to provide high-speed, high-reliability computation for Yokogawa CENTUM VP Distributed Control Systems (DCS). Operating with CENTUM VP R6.05 or later versions of Field Control Station functions, the CP471-00 module ensures fast signal execution, advanced process logic evaluation, and stable system performance across complex automation environments.
Dual-Redundancy & Hot-Swappable Design
System reliability is paramount in industrial process automation. The CP471-00 supports a dual-redundant hardware architecture, allowing two CP471 processor modules to be mounted together on a duplexed field control unit. In the event of a module check or failure, control seamlessly transitions without interrupting active process loops. Furthermore, in dual-redundant configurations, online module replacement can be performed while the system is live, significantly enhancing maintenance efficiency and preventing unplanned operational shutdowns.
Seamless Integration and Compatibility
Engineered for exact field control unit integration, the CP471-00 standard non-explosion protection basic model is compatible with multiple Yokogawa Field Control Units, including AFV30, AFV40, A2FV50, and A2FV700 series. It operates efficiently in combination with style code S3 or later of the EC401 ESB bus coupler module, ensuring smooth high-speed communication within the DCS network.
Upgrade Path for Legacy Systems
The CP471 processor module serves as a direct hardware upgrade path for existing field control stations using CP461 modules. When updating system software to CENTUM VP R6.05 or later, existing CP461 modules can be replaced with the higher-capacity CP471 to meet increased processing demands and improve overall DCS capability.

FAQ
Q: What control software version is required to run the CP471-00 module?
A: The CP471-00 requires CENTUM VP R6.05 or a later version of the Control Function for Field Control Stations.
Q: Can CP471-00 be installed alongside an older CP461 module in a dual-redundant unit?
A: No, CP471 cannot co-exist with a CP461 module in the same dual-redundant pair. However, a full pair of dual-redundant CP461 modules can be online-replaced with a pair of CP471 modules.
Q: Which bus coupler module is compatible with CP471-00?
A: The CP471-00 can be combined with style code S3 or later of the EC401 ESB bus coupler module.
Q: Can the CP471-00 be replaced while the system is running?
A: Yes, in a dual-redundant configuration, online replacement of the CP471 module can be safely performed.
