SCADA is not a specific technology, but a type of application. SCADA stands for Supervisory Control and Data Acquisition  any application that gets data about a system in order to control that system is a SCADA application.


A SCADA application has two elements:

  1. The process/system/machinery you want to monitor a control this can be a power plant, a water system, a network, a system of traffic lights, or anything else.

  2. A network of intelligent devices that interfaces with the first system through sensors and control outputs. This network, which is the SCADA system, gives you the ability to measure and control specific elements of the first system.
