Now -- Can you do it with ONE timer, not two??

The tutorial is now updated after adding a tutorial for making the flasher with only one timer.

If you use Allen-Bradley RSLogix, you can replace the "Init" bit with a Timer 1 Done bit (T4:1/DN), then only two rungs are needed. The second rung gets deleted.

You are right but I'm using OMRON PLC, timers don't have a done bit.

Too bad for you!

Actually, the only bit they have is a done bit. It's the timer's contact. Therefore, what Lancie said is correct.

If you use mitsubishi you dont need a timer M8012/13/14 are special relays that are continually going on/off for a specified time

Maybe Omron has this capacity as well
