The Yokogawa CP345-S1 is a high-performance Processor Module engineered for the CENTUM CS 3000 and CENTUM VP Distributed Control Systems (DCS). As the central processing core of a Field Control Station (FCS), this module executes user-defined control programs, manages real-time process data, and facilitates high-speed communication between I/O modules and the system network. The "S1" designation signifies a specific hardware revision (Style 1), optimized for unparalleled reliability in demanding industrial automation environments.
To ensure maximum system availability, the CP345-S1 supports dual-redundant configurations, allowing for seamless failover in mission-critical applications. This module is built with large onboard memory to handle complex regulatory control and sequence algorithms with ultra-low latency. Its ruggedized physical design is specifically tailored to withstand industrial challenges such as electromagnetic interference, vibration, and temperature fluctuations. Whether deployed in a refinery or a power generation facility, the CP345-S1 provides a stable foundation for continuous process operations and advanced diagnostic monitoring.
