The YOKOGAWA CPU451-10 Processor Module is a part for an industrial automation system.

A Distributed Control System (DCS) is a computer-based system used to automate, monitor and control complex industrial processes. It is typically used in large plants such as refineries, power plants, chemical plants, and paper mills.

A DCS consists of several components that work together to control the process. These components include:

• Controllers:These are devices that receive input from sensors and send output signals to actuators. Controllers use pre-programmed logic to control the process.
• Sensors:These are devices that measure physical quantities such as temperature, pressure, flow, and level.
• Actuators:These are devices that control physical processes such as opening and closing valves, starting and stopping motors, and adjusting dampers.
• Operator stations:These are human-machine interfaces (HMI) that allow operators to monitor the process, make changes to setpoints, and troubleshoot problems.
• Communication network:This network connects all of the components of the DCS together.
