If I'm understanding it correctly.
your DII is using 10h, which is Bit (0001 0000) in Slot 3. or I:3/4 to operate the inturrupt.
you can look at the help file in rslogix 500 and get info on what each of the items in the DII section of the processor file are doing. But I also found this, which explained a little differently.
