In 2001, Rockwell Automation first shipped the L43 CompactLogix (Bulletin 1768) controllers, targeted at small- to medium-size automation solutions. At launch, the CompactLogix Controller was intended as the long-term replacement for the SLC-500 controller family. The CompactLogix control platform was designed with an emphasis on the controller software. As the CompactLogix hardware evolves with improved performance and additional features, the logic can easily be migrated to new hardware and firmware versions.
