Distributed Control System
Distributed control system (DCS) is a sophisticated control system for a plant or a process consisting of many controller loops that are usually autonomous controllers distributed throughout the process without any central operator supervisory control.

Conclusions

The distributed control system is one of the popular control systems specially designed with diagnostic and redundancy capabilities to enhance the controller performance and reliability. This system provides greater flexibility to control operating stations and field devices with high productivity and minimize production costs.
It is the era of technology, and the industrial automation system requires an advanced automation control that should have more control over the old age used complex processes.
The distributed control system is specially designed for the industrial complex, geographically distributed, and extensive processes. In this system, the controllers are distributed throughout the entire plant.
These controllers are connected with the operating PCs and field devices with the help of a high-speed communication system.
Communication buses are used to connect the input devices such as sensors and actuators to the output controller modules such as pumps, heaters, valves, etc. The sensors, actuators, or smart devices can communicate with the other controllers or program logical control systems.
