    Hello All,

    Do PLC's use logic gates or Logic Ladders?

    I've been asked to explain two different types of stop/start/retain relay control circuits for suitable for either the AC or DC

    I'm going to compare an electro-magnetic relay system with an electronic logic or PLC system but I'm not sure if I'm getting a PLC and Electronic logic system mixed up or they are both the same?

    Replies would be gratefully appreciated.

    PLC use logic ladders. However, logic gates can be implemented on PLC using ladder diagrams. the problem given to you can be solved using ladder logic with a proper flowchart to solve the problem
