SCADA system overview
A SCADA system, or Supervisory Control and Data Acquisition system, is a software and hardware combination used to monitor and control industrial processes and equipment in real-time. The system collects data from sensors and other devices, processes the data, and presents it to human operators who use the information to make decisions about how to manage the industrial process. SCADA systems are widely used in industries such as oil and gas, water treatment, manufacturing, and transportation. The SCADA system is made up of several components, including sensors, Programmable Logic Controllers (PLCs), Remote Terminal Units (RTUs), Human-Machine Interfaces (HMIs), and the central server or control room. The sensors are used to measure variables such as temperature, pressure, flow, and level. PLCs and RTUs are responsible for receiving the sensor data and carrying out control actions such as turning on or off a valve or pump. HMIs provide a graphical user interface (GUI) for operators
