SCADA is an abbreviation created by reading the first letters of the words "Supervisory Control and Data Acquisition." SCADA, a comprehensive and integrated database control and monitoring system, provides automatic control, monitoring and reporting of all electronic units of a facility or operation. SCADA systems are expected to perform the functions of monitoring, controlling, collecting data, recording and storing data. The SCADA systems can operate in continuous, intermittent, repetitive or discrete modes in industrial processes, manufacturing, production, power generation, wastewater treatment, oil and gas pipelines, electricity transmission and distribution, wind generators, civil defense siren systems and major communication systems , water treatment and promotion centers in the sectors. May include public and private facilities, including space stations. Access to heating and ventilation systems (HVAC) and control and monitoring of energy consumption may be required. SCADA's maximum benefit will continue to be from the greatest needs of industrial installations in terms of safety and convenience.
