that would mean that the first out put will be I:12/0 sorry before i used a fullstop the first input on the second card will be I:12/16 and the first output will be O:12/31
how does that sound?
try it when it is all working by wiring inputs to the cards ones that are all on the time, they should show up in the table
also put ones in the output datatable they should light up the LED's on the output card.
cheers
