Possible to make "one Shot" in LOGO8?

Is there any ways to make any one shot to protect the delay in the circuit?

In the Sim. all the delay i set are count again when i push input button twice,

What key i can use ,for example i make 2's delay on and after 15's off ,so this total 17's can it be protect by some key that even i push button twice in 17's??

thanks

Have a look at this one.

After selection from the push button for 2 sec. the Q1 is active and it can not be retriggered for another 15 sec.

The latching relay keeps the input of the timer off until the end of the timer

 Yes! It works!thanks!
