Introduction of SCADA Prior to the introduction of SCADA, producing floors and modern plants depended on the manual control and screen utilizing press catches and simple hardware. As the size of the enterprises and assembling units developed in size, they began utilizing transfers and clocks, that gave administrative control to a limited degree. Shockingly, transfers and clocks had the option to tackle issues just with insignificant computerization usefulness and reconfiguring the framework was troublesome. Thus, a progressively productive and completely robotized framework was required by all enterprises.  PCs were produced for modern control purposes in the mid-1950s. Gradually, the telemetry idea was presented for virtual correspondence and transmission of information. Around the year 1970, the term SCADA was begotten alongside the development of Microprocessors and PLC ideas.
