I'm running an AOI on a CompactLogix L33ER.
In the AOI I trigger a TON (Local Tag) with a input parameter bit (HMI Enable Pushbutton). I have a coil (Output Parameter) that is branched around the TON. The coil is energized if the TON is not done.
However, this doesn't work. After troubleshooting the logic, it appears as if the TON (which has a preset of 3600000) is instantly done and therefore my Coil never gets energized (because it is only energized if the TON is not done). If I remove the XIO the Coil does energize but the TON does not time.
This is really simple logic. Is there some reason a CompactLogix cannot do a TON in an AOI? Does anybody see anything obvious that I'm missing (usually at this point I have a 'duh' moment)?
Thanks for any direction! I can't find anywhere in Rockwells 'support' that says this shouldn't work and I've done this logic only a million times over the years (although maybe not in an AOI).
