Power line current must flow through the Switch contact in order to turn ON the load Lamp In fact there should be a second vertical line on the right end of the ladder diagram to provide a return path for the current flow but this is omitted to simplify the circuit diagram Now if instead of wiring the switch to the lamp directly as suggested in the above diagram you could connect the switch to the PLC s input and connect the lamp to the PLC s output and then write the above ladder program to perform the same job Of course it makes little sense to use a PLC if that is all you want to do We will see how a PLC can simplify wiring shortly Note The contact Switch shown in the above diagram is termed a Normally open N O contact Now let s say if there are 3 switches that must work together to control the lamp A Master switch must be ON and one of the two control switches controlsw1 and controlsw2 must be ON while the other must be OFF in order to turn ON the lamp think of two way switches in your house and you will get the idea We can wire all 3 switches to 3 inputs of the PLC and the lamp to the output of the PLC We can write the following ladder program to perform this task Master control2 WW controls Lamp OUT controlSwi control Sus A contact with a across its body is a Normally Closed N C contact What it means is that the ladder program is using the inverse of the logic state of the input to interpret
