Product Overview

CP471‑00 S1 is a field control processor module for Yokogawa CENTUM VP distributed control system. It executes process control algorithms, manages I/O data exchange and handles system communication tasks. Dual‑redundant hot‑standby deployment allows online module replacement without process interruption. Dual‑Ethernet interfaces support plant‑system network communication. Large RAM and flash storage support complex control strategies and local data logging. Widely stocked as refurbished / new‑old‑stock spare parts for petrochemical‑plant, refinery and power‑plant DCS maintenance projects.

Application Notes

‑ Requires matching EC401 coupler module and R6.05 or later system software version. ‑ Cannot mix CP471 and CP461 in redundant pair configuration. ‑ Follow Yokogawa official hot‑swap operation procedures for redundant‑system maintenance. ‑ Typical deployment: oil‑gas processing plants, refineries, power‑generation DCS spare‑part stocking.
