Use Counter as Timer in Omron Zen PLC Programming

Make Counter to Work as Timer in Omron Zen PLC :-

If it is required to use more than 16 timers and counters are free than we can make the plc logic in such a way that counter will work as timer. Suppose that we need a timer of 10 seconds , another timer of 15 seconds and third timer of 20 seconds. Then first of all make a timer with preset value as 1 second. Note :- Take the timer as flashing type i.e the timer will remain on and off simultaneously for the value set until the input condition is true.

After that make 3 counters and in the preset value put 10 , 15 and 20 seconds. And in the input condition of all the counters put the Timer Done bit. So in this way these counters will behave as timer of 10 second , 15 second and 20 seconds.
