ControlLogix and CompactLogix (including the newest 5080 and 5069 family controllers) use Studio 5000 software, which is different from RSLogix 500 and the SLC-500/MicroLogix family.
While the ControlLogix operating system and controller family has been on the market since 1998, you asked what the "latest" Allen-Bradley controllers are. The new CompactLogix 5069 series are the most recently introduced controller and I/O platform.
If you are unfamiliar with ControlLogix and CompactLogix, you can learn the basics on any member of that family, with RSLogix 5000 (prior to v21) and Studio 5000 (v21 and later) software.
Studio 5000, even in its smaller CompactLogix-only editions, is a relatively expensive software toolset.
