You could have used either RSLogix Micro (only supports MicroLogix) or RSLogix 500 (also supports SLC)
As git noted, since this is a ML 1000 even the free "Micro Starter Lite" version can be used.
Thanks guys, I appreciate the help. I did get RSLogix installed and actually remembered the password on the first try! That video that drbitboy recommended really helped. Thanks again!
