Supervisory control and data acquisition (SCADA) is a control systemarchitecture that uses computers, networked data communications andgraphical user interfaces for high-level process supervisory management, but uses other peripheral devices such as programmable logic controllersand discrete PID controllers to interface to the process plant or machinery. The operator interfaces which enable monitoring and the issuing of process commands, such as controller set point changes, are handled through the SCADA supervisory computer system. However, the real-time control logic or controller calculations are performed by networked modules which connect to the field sensors and actuators.
