Yokogawa CP345 | CENTUM CS 3000 R3 | Dual-Port Processor Module

Product Overview

The CP345 (Style S1) is a high-availability processor card designed as the primary control engine for Yokogawa’s CENTUM CS 3000 R3 Distributed Control System (DCS). Operating within a Field Control Station (FCS), the module manages intensive regulatory control, sequence logic, and real-time data synchronization.

Equipped with a dual-port Vnet interface, the CP345 ensures redundant communication pathways across the system bus. This architectural redundancy prevents process disruptions during network failures or hardware malfunctions. When deployed in a 1:1 redundant pair, the CP345 provides seamless failover capability, maintaining deterministic control in high-stakes environments like petrochemical plants and utility power grids.
