SCADA
SCADA is a supervisory system used to monitor and, where authorised, control industrial equipment using data from PLCs, RTUs, sensors and other field devices.
SIMPLE EXPLANATION
Supervisory Control and Data Acquisition in context
SCADA software collects selected device data, displays it in operator screens, records history and manages alarms. It normally supervises control systems rather than replacing the local PLC logic.
Example
A water treatment operator can use SCADA to see pump status, tank levels and alarms from several sites in one interface.
