Have you thought about using internal pulses? Have a look in the manual and see if you can find them.

two quick suggestions... you could use a status bit, or you could click on downloads and check out how others got the crosswalk light to blink. hope this helps

Few ways to do it:
1. Use a self resetting timer and then use the timer done to drive a flip flop.
2. Use a self resetting timer and the LIM instruction.
3. Use 2 timers, one for the on time, and one for the off time.
Either method can be used to generate an on/off pulse.
You will have to decide how the pulse is used in your application.
