Many industrial automation machines and robots are built using PLCs, ladder, SCADA and some also interface with other software applications using C# and Dot Net using Visual Studio.
To learn about SCADA one can use the internet and then buy some PLCs, inverters, electric motors, relays and relay driven values (if it is to be used with hydraulics or compressed air). In large factories they also use UPS, Panels, switch boards and transformers to give the right voltage to each PLC, inverter, mot…
