SCADA APPLICATION


SCADA is the abbreviation for Supervisory Control And Data Acquisition. The
term SCADA usually refers to centralized systems which monitor and control entire
sites, or complexes of systems spread out over large areas (on the scale of kilometres
or miles). Most site control is performed automatically by remote terminal units. A
PLC may control the temperature of a furnace through part of an industrial process,
but the SCADA system may allow operators to change the set points for Temperature,
and enable alarm conditions, such as loss of flow and high temperature, to be
displayed and recorded.
