Help please: Conquest T42 bar feed macro variables

[MadMax]

We're having problems with our bar loading macro not recognizing when the loader wants to load a new bar. The first bar loads fine, but the lathe is not seeing the new bar signal between parts on subsequent loads. Feeding part to part works fine, but bar loading is buggered. At the end of the bar, the lathe misses the end of bar signal from the loader and goes into the part feed routine.

We're getting the right signal outputs from the loader, but it looks like the load macro isn't recognizing the new bar signal.

Our equipment:

-Conquest T42 Fanuc 18-T
-LNS Quickload S3 loader

Poking around in the macro, we see that a #1008 variable must greater than 0.5 to call M61 so it looks like the #1008 condition isn't being met.

Does anyone know how the #1008 variable is set? Is there a listing of system variables and what hardware pins they point to?
