SCADA is a control and data acquisition interface software, installed on computers (often PCs) and used with industrial automation controls (PLCs). They are generally developed by automation product manufacturers, (Rockwell, Siemens, Invensys, by some independents) (often bought by larger automation industries, look at wonder ware, Citect, In-touch), and sometimes by individuals who like their own interfaces in Visual C, Delphi? Communications are carried out over specialized buses such as Modbus, Profibus, Fieldbus, Industrial Ethernet? and the sensors, drives, motor controllers are designed to exchange with the PLCs over such links.
