Whether you are new to automation or an experienced professional, this guide will help you understand the fundamentals of SCADA and make better choices for your applications.
What is SCADA?
SCADA stands for Supervisory Control and Data Acquisition. It is an industrial software system used to monitor, control, and analyze real-time processes in factories, plants, and large-scale infrastructure such as power grids, water treatment facilities, and oil & gas pipelines.
SCADA provides a centralized platform where operators can view live data from sensors and PLCs, receive alarms, control equipment remotely, and store historical data for performance analysis. In simple terms, SCADA connects machines, sensors, and controllers with humans, making complex processes easier to manage and safer to operate.
What is SCADA Software?
SCADA (Supervisory Control and Data Acquisition) software is an industrial automation tool that helps monitor, control, and analyze real-time processes. It connects to devices like PLCs, RTUs, and sensors to collect live data from machines, equipment, and plants.
The main role of SCADA software is to give operators a clear visualization of processes on their screens, generate alarms when something goes wrong, and store historical data for reporting. This makes it easier to manage large and complex industrial systems safely and efficiently.
