In this paper, a scheme for closed loop speed control of DC motor in four quadrants using Programmable Logic Controller (PLC) is discussed. The armature voltage is varied using a Class E chopper circuit. The individual switches in the chopper circuit are switched using Pulse Width Modulation (PWM) control signals generated by PLC. Duty cycle of PWM...

... The SCADA system design starts through programmable logic controllers (PLCs) or remote terminal units (RTUs), which link various components including manufacturing equipment, human machine interfaces (HMIs), sensors, and end devices. 1 This reduces human error, also addressing issues such as data tampering. A SCADA system is a data collection system with supervisory control for local industrial processes, however, an IoT system is the next step in connectivity and communication technology. ...
