If memory serves me correct, you can have up to 44 digital ports and I don't believe the vm counts as part of that. However, I also seem to remember that you can't put in more than 2 station boards. You may have to switch out the 2nd dtib 12 with a dtib 24 and you may have to re-number your vm ports in fl. 30 and fl. 65.Hopefully someone else will chime in.
