RIO is not all that hard to understand. Just remember where a bit ends up is dependent on your addressing scheme. If you've got the gear, there's no reason not to use it.
So as dmargineau said, word 0 is status because your ASB module is residing in slot 0 of your remote rack. If your first input module is in slot 1 (and the SN module is in Slot 6 of main chassis) then in the data table you would address it: I:6.1 with input 0 being bit 0, input 1 being bit 1, etc.
If slot 2 of the remote chassis has an output module, then you would address that: O:6.2.
(We'll not worry about complementary I/O for now).
Out of curiosity: How much I/O do you need? Does it all need to be in remote chassis (i.e. remote locations)? If your I/O doesn't need to be in a remote location you might consider something out of the MicroLogix line (1100, 1200, etc). In addition to the onboard I/O, they support varying levels of expansion I/O and are every bit as capable as the SLC's. More so, in many respects. They also use the same programming sofware (RsLogix 500) as the SLC's. Just a thought.
