SCADA (Supervisory Control and Data Acquisition) is a system of hardware and software components used to monitor and control industrial processes and infrastructure such as manufacturing plants, power generation facilities, and water treatment plants. It allows operators to remotely monitor and control various aspects of the system in real-time, collect and analyze data, and make informed decisions to optimize operations, improve efficiency, and ensure safety. SCADA systems typically consist of sensors, controllers, communication networks, and a user interface for operators to visualize and interact with the data. These systems play a crucial role in the automation and management of complex industrial processes.
