Product Overview

The CP471-01 S1 is a high-performance central processing unit (CPU) engineered for the Yokogawa CENTUM VP Distributed Control System (DCS). Operating as the core intelligence within Field Control Units (FCU), it executes real-time process control, advanced logic calculations, and high-speed data acquisition with deterministic performance.

Designed for large-scale industrial automation, the CP471-01 S1 delivers a substantial performance improvement over previous-generation processors. It is optimized for AFV30S/D and AFV40S/D control units, ensuring fast synchronization and stable control across the Vnet/IP plant network.

FAQ

What differentiates Style S1 from later CP471 revisions?
Style S1 represents the initial hardware release of the CP471 series. While later styles (e.g., S2) may offer component or lifecycle improvements, the S1 provides the same core control functionality for CENTUM VP R6 systems.

Can the CP471-01 S1 replace a legacy CP461 module?
Yes. The CP471-01 S1 is the designated successor to the CP461. Verify that the installed CENTUM VP software version supports the CP471 hardware profile before replacement.
