A SCADA system typically includes the following components:
Human-Machine Interface (HMI): The HMI is the interface through which operators interact with the SCADA system. It displays process data and allows control commands to be issued. Remote Terminal Units (RTUs) and Programmable Logic Controllers (PLCs): These are field devices that interface with sensors and actuators to gather data and control processes. Communication Infrastructure: This includes the network and communication protocols that allow data to be transmitted between field devices and the central SCADA system. SCADA Software: The software is responsible for data acquisition, processing, and visualization. It also handles alarm management and historical data storage.
