SCADA (Supervisory Control and Data Acquisition) is a control system architecture that allows industrial organizations to monitor, gather, and process real-time data from various types of sensors and devices. The SCADA system provides a graphical user interface that allows operators to view and control the entire system from a central location.
A SCADA system typically consists of a human-machine interface (HMI), remote terminal units (RTUs), programmable logic controllers (PLCs), communication networks, and data servers. The HMI allows the operator to view and interact with the system through a graphical user interface. The RTUs and PLCs are responsible for collecting data from sensors and controlling the system. The communication networks allow data to be transmitted between the RTUs, PLCs, and data servers.
SCADA systems are widely used in various industries, such as water treatment plants, power plants, oil and gas refineries, and manufacturing plants. These systems provide real-time monitoring and control of critical processes, allowing operators to make informed decisions and respond quickly to changing conditions. They also help to improve system efficiency, reduce downtime, and enhance safety.
Overall, SCADA systems are an essential component of modern industrial control systems, providing a high level of automation and control that is critical for maintaining the smooth operation of complex processes.
