A SCADA system is a mix of hardware and software that allows for the collection of data and the automation of industrial processes. SCADA links sensors that monitor equipment such as motors, pumps, and valves to a local or remote server.
A PLC is a physical piece of hardware. SCADA, on the other hand, is a piece of software. A PLC is tangible in this regard. A PLC can be held and examined. SCADA, as software, operates on a computer system and is comparable to an operating system such as Windows.
While both are "control systems," SCADA, with the help of multiple components, provides higher capabilities than the PLC. To match design objectives while becoming more cost-efficient, you should ideally employ the capabilities of both types of control systems (in the long run).
SCADA systems are used to regulate and monitor physical processes, such as power transmission, gas and oil transit through pipelines, water distribution, traffic lights, and other systems that serve as the foundation of modern society.
SCADA is used in a variety of industries, including water and wastewater systems, electric generating, transmission and distribution systems, and oil and gas systems. SCADA is also used extensively in manufacturing plants, food processing facilities, and mass transit systems.
