Tango,
It is the old traffic light program. It has been solved, discusssed, debated, and condemmed on this site for years and years. Surely with a little searching, AnthonyWade can find what he needs.
I will give him some little hints anyway.
1. You can use 6 timers (1 will do), but remember it is a cycle, it should continue to loop. You never want your lights to stop working. When your timer T4:5 finishes, that is the end of cycle and T4:0 should be reset and start the cycle again at 0 seconds. The easiest way is to put a T4:5/DN XIO on Rung 0
2. Go back and do what you should have done first, that is to make a timing diagram showing what time each color light goes on, and what time it goes off.
3. Now look to see if some lights can be defined as combinations of other lights. For example, the red lights should be controlled by just two different timer DN (Done) bits (in series for one red light, in parallel for the other one), while all the others can be controlled by a different single TT (Timer Timing) bit.
4. You are shooting for a 26-second cycle, so set your timers for 80, 40, 20, 80, 40, 20. That gives a 28 second cycle, but the extra 1 second for each Delayed Green results in no crashes.
