The full form of SCADA in the electrical field is Supervisory Control and Data Acquisition. It is a computer system that gathers and covers real-time data. SCADA systems are deployed in a wide range of industries to track production processes and equipment. These computerised systems were first deployed in the 1960s. These are used by production companies to regulate the industry in remote places and globally. A SCADA system is based on a human-machine interface (HMI) to communicate with different parts of machinery such as pumps, valves, motors, sensors, etc. In this blog, you will learn more about SCADA, its applications, and how it works.
How Does SCADA Operate?
A SCADA system is an amalgamation of two electronic devices- programmable logic controllers (PLCs) and remote terminal units (RTUs). These devices communicate with multiple objects like industrial machinery, end devices, sensors, and HMIs. RTUs and PLCs transport data from the aforementioned objects to computer systems using Supervisory Control and Data Acquisition software. The software then analyses, transports, interprets, and displays data to related operators, helping them make decisions.

Features of SCADA
Some of the critical features of a Supervisory Control and Data Acquisition system are:
- It can extract data from the past, store real-time data, and present the data graphically.
- It can handle alarms to intimate operators about salient features of the current system of a factory or production facility.
- It helps in report generation after getting a report template manually.
What is SCADA Used for?
SCADA software is used in various industries to assess old data, enhance efficiency, reduce outages, and manage industrial processes. Its common applications include controlling, monitoring, and analysing different devices and processes. This software has become a quintessential part of the following industries:
- Transportation
- Manufacturing
- Energy
- Oil and Gas
- Food and Beverage
- Wastewater Treatment
