What is DCS？

A Distributed Control System (DCS) is a computer-based system used to automate, monitor and control complex industrial processes. It is essentially a large network of controllers that are distributed throughout a plant or facility, all working together to keep the process running smoothly.

Here’s a breakdown of how a DCS system works:

1. Sensors:These devices collect data from the physical process, such as temperature, pressure, flow rate, and level.
2. Controllers:These are programmable devices that receive data from the sensors and send control signals to actuators.
3. Actuators:These devices take physical action based on the signals they receive from the controllers, such as opening or closing valves, starting or stopping pumps, or adjusting heater settings.
4. Operator stations:These are the human-machine interfaces (HMI) that allow operators to monitor the process, make changes to setpoints, and troubleshoot problems.
5. Communication network:This network connects all of the devices in the DCS system together, allowing them to share data and control signals.
