AB 1400A more questions

Thanks to the generous contributions of the forum members, I'm making real progress. I only have one or two remaining issues. The big one is, after I store multiple pulse delays as integers in files N10 and N11, I compare them to a master pulse count. When they are equal, it is time to open the gate on the conveyor. I have the ouput in a subroutine followed by an IOM instruction. The output goes true but then I can't get it to turn false again. I need it true for about 100ms. I've tried the output unlatch followed by IOM and that doesn't work. If any of this makes any sense and you can help......I'd really appreciate it.

Can you post your code, pdf or logix file (pdf will get more help possibly)
