Timing and counting are two different functions. If you need to time, you need a time base of some description. If you can create that in logic, and then count the events, well, then you have a timer using counters, but it is going way out of your way to accomplish something that is easier to do with a timer in the first place. There are some fixed rate toggling bits in the LogixPro S:2 file that might be used as some kind of timing base, so go for it and post your results.
