YOKOGAWA CP471-00
Yokogawa CP471-00 Processor Module
Product Description
The Yokogawa CP471-00 is a high-performance processor module (CPU) designed for use within Yokogawa’s CENTUM VP Distributed Control System (DCS). As the central processing unit, the CP471-00 is the “brain” of the field control unit (FCU), responsible for executing control logic, managing process data, and facilitating communication with I/O modules and the broader CENTUM VP system.
This module is built for robust and reliable operation in demanding industrial automation environments, found across a wide range of industries including chemical, power generation, oil & gas, petroleum, and pharmaceuticals. It’s capable of handling critical tasks such as real-time process monitoring, data logging, sequence control, and complex control algorithms.
A key feature of the CP471-00 is its support for dual-redundant configurations. Two identical CP471 modules can be used together in a duplexed field control unit to provide high availability and fault tolerance, ensuring continuous operation even in the event of a primary module failure. It comes with built-in memory backup, typically via a battery, to protect data during power outages, and it includes LED indicators for easy status monitoring. The module also features dual Ethernet ports for robust network connectivity.
