If any three inputs are on, am alarm siren sounds.If any two inputs are on, the red pilot light goes on.If one input is on, the green pilot light goes on, nothing happens.
There are three hazard inputs to the alarm systems that go on as some operational malfunction occurs. If any one of the stop button is turned ON the conveyor will stop.ģ.
#Contador omron cx programmer series#
Write a Logic to control a conveyor which has to ON when any one of the 3 start buttons is pressed, and it should stop when any one of the 3 stop buttons is pressed. To turn OFF the output Q100.00 we have to use RST coil, hence I0.01 Stop Button connected to the RST coil Output with address Q100.00.Ģ.Start button I0.00 is a Push button and it gives a pulse signal to the right side rung hence by using the SET coil we can hold the output Q100.00 in the high state, and it will be in ON state until it reset.When we are using the push button either we need to use latch to hold the output or else we can use SET and RST coil function. I0.00, I0.01 are the inputs considered as Start and Stop Button. b) Write the same ladder logic without latches.
