DCS is widely used in industries such as oil and gas, chemical, and power generation, where precise process control is required for safety and efficiency. DCS provides advantages such as improved process control, increased production efficiency, reduced maintenance costs, and increased safety.
SCADA is a control system that is meant to monitor and control entire industrial processes or systems rather than individual pieces of equipment. SCADA systems are used to manage and control large-scale industrial processes such as water treatment plants, electricity generation plants, and transportation systems.
The RTUs or PLCs in a SCADA system are responsible for collecting data from various sensors and sending it to the central server for processing. The data is processed by the central server, which delivers real-time feedback to the operators through operator stations.
The SCADA system consists of several components, including −
Remote terminal units (RTUs) − RTUs are distributed throughout the plant or process and are responsible for collecting data from multiple sensors and sending it to a central server. Based on the commands received from the central server, RTUs are also responsible for controlling other process variables, such as valves and motors.
Programmable logic controllers (PLCs) − PLCs are similar to RTUs, but they control smaller plants or processes. PLCs are responsible for collecting data from sensors as well as controlling multiple process variables.
Sensors − Sensors are used to measure variables such as temperature, pressure, flow, and level in processes. Sensors send data to RTUs or PLCs for processing.
Communication network − The communication network connects all of the SCADA system's components, allowing data to be exchanged between RTUs or PLCs and the central server.
Central server − The data collected from the RTUs or PLCs is processed by the central server, which then delivers real-time feedback to the operators through operator stations. In addition, the central server maintains previous data for analysis and reporting.
