SCADA changed Industry

Supervisory Control & Data Acquisition is a computer system for gathering and analyzing real-time data. 

SCADA systems are used to monitor and control a plant or equipment in industries such as telecommunications, water and waste control, energy, oil and gas refining, and transportation.

SCADA is a system of software and hardware elements that allows industrial organizations to:

• Control industrial processes locally or at remote locations
• Monitor, gather, and process real-time data
• Directly interact with devices such as sensors, valves, pumps, motors, and more through human-machine interface (HMI) software
• Record events into a log file

SCADA systems are crucial for industrial organizations since they help to maintain efficiency, process data for smarter decisions, and communicate system issues to help mitigate downtime.

The basic SCADA architecture begins with programmable logic controllers (PLCs) or remote terminal units (RTUs). PLCs and RTUs are microcomputers that communicate with objects such as factory machines, HMIs, sensors, and end devices, and then route the information from those objects to computers with SCADA software.

Also, SCADA software processes distribute, and displays the data, helping operators and other employees analyze the data and make important decisions.

Lets have a look of SCADA application for a Boiler.

For example, the SCADA system quickly notifies an operator that a batch of products is showing a high incidence of errors. The operator pauses the operation and views the SCADA system data via an HMI to determine the cause of the issue. The operator reviews the data and discovers that Machine 4 was malfunctioning. The SCADA system’s ability to notify the operator of an issue helps him to resolve it and prevent further loss of product.
