PLCs assignment 2 Explain how a steppe a stepper motor could be driven by a PLC. What type of interface is Xplain how a shaft encoder is used to provide a digital input to a PLC. Why a number represented in different forms in a PLC i.e. why are some numbers represented in different forms in a PLC. Give example of the use of: Hexadecimal, binary, and BCD.
