Yokogawa CP701 | CENTUM CS 3000 | Field Control Station CPU Module

Product Overview

The CP701 (Part # CP701) is a high-availability processor module serving as the computational core for Yokogawa’s CENTUM CS 3000 and CENTUM VP Field Control Stations (FCS). Designed for the S1 hardware generation, this module is purpose-built to execute real-time regulatory control strategies, complex sequence logic, and advanced math functions with high-speed determinism.

Reliability is central to the CP701 (Style S1) architecture. It facilitates seamless communication across the Vnet/IP or VL-net system bus, ensuring synchronized data flow between the field level and the Human Interface Station (HIS). To eliminate process downtime, the CP701 supports 1:1 dual-redundant pairing, enabling instantaneous failover without affecting active control loops. This makes it a standard choice for mission-critical industries such as oil and gas refining, chemical manufacturing, and power generation.
