we want to turn a lamp on and off continually on and off period are 2 seconds and 3 seconds simultaneously ,all this process is controlled by a toggle switch , when the switch is on the flasher lamp is flashing when the toggle is off the flasher is too off

we have two inputs , high and low both are toggle switches ,when the low input is true the flasher light shall be flashing 1 second on and 1 second off. if the high input is true then it will be flashing 0.5 second on and 1 second off . if both inputs are true then the flasher shall work for 0.5 second on and 0.5 second off
3-
simple motor starter operation using the traditional star/delta connections changing it is required that the motor start (star) connection and after 5 seconds it automatically should switch into the (delta)connection
here we are using two normally open push buttons to start and stop the motors. we use two PLC outputs to operate the contactors of star/delta connection
