[Squeeze 10lbs Of Shi.. Into A 5lb Bag?]

Hi, I have 18 different jigs that go into a fixture (called a door), currently we have 4 different programs, due to the fact that only 9 jigs can fit into one program, we have 12 doors, some with light curtains and some with air operated doors that protect operators from operation. Eventually all the doors will have light curtains, so that there would only be two programs instead of four. I want to be able to have only one program in all the doors that will be able to run all the jigs (hopefully not wishfull thinking on my part) Now I'm no expert at omron PLC's, we have CJ1G-H, some have CPU42 and some have CPU43. Looking at memory view I see the total steps available are 11,264 with each jig on an avg use 1200 steps, I'm working on improving the logic to reduce this number, but even after that is done I don't think I will be able to get all 18 jigs into one program. Is there a way based on which jig is in the door (currently Binarys and nodes are used to determine this) to load up the logic needed from a datatable or something without having to be connected to ethernet? Or am I doomed to having to setup certain doors that use only certain jigs? The outfit that did all the eletronics and porgramming for these jigs and doors did a very good job, in no way am I knocking their accomplished work, I'm just trying to improve the logic a bit and see if I can get everything into one program. Thanks in advanced! Deke2006
