A supervisory control and data acquisition (SCADA) system is an industrial control system that allows organizations to collect, analyze, and visualize real-time asset data in order to monitor and control industrial processes at local or remote locations. A SCADA system is typically made up of the following components:

  • Sensors, actuators, and other field devices
  • Field controllers that interact directly with sensors, actuators, and field devices, such as programmable logic controllers (PLCs) and Remote Telemetry Units (RTUs)
  • Human machine interfaces (HMIs) that graphically or visually displays data to operators in an understandable way
  • A communications network that connects field hardware to the SCADA system
    SCADA software
