Ladder logic is one of the basic programming language in plc, In general we use electrical wires to do the control circuit of any equipment by connecting stop, start, timers or contactors etc..to control the output. on the same way if we want to control the motor action by PLC, we use ladder logic which is written in plc programme between two vertical lines called phase & neutral or bus bar. where we draw the lines by inserting NC, NO contacts by joining timers or counters or output coils which means a motor or any load which u want to control it.

what is the different betweem earthing and neutral?
