Assigning bits to nputs and outputs

Hello all,
I recently received a copy of RSLogix 500 and have been messing around with it as time permits.
I'm extremely new to this so please be patient. My question is, is there a way to assign or associate the binary bits (B3's) to the inputs and outputs or do you have to include them in a rung to turn on when the input turns on? It seems like there would be a way, but I'm not seeing it.
Thank You.

Yes,, you perform the transfer in rungs. You can transfer them a whole word (16 bits) at once with a MOV

Thanks Bernie!
