  • Central Station (Master station)
  • Remote Terminal Units or RTU
  • Communication lines for sending and receiving data and commands or Data Link

Control and monitoring performed by SCADA ivs done through collecting information of remote terminals and sending them to the central computer via communication lines for processing and perform necessary operations. After processing and decision-making, the central computer sends necessary commands to remote terminals via communication lines, they adjust the system by received commands. Communication between terminals and the central computer can be in various ways such as public phone systems, VHF, UHF, Fiber Optics, Radio and Satellite network.
