The Allen-Bradley CompactLogix 1768 series (1768-L43, 1768-L45) is a discontinued mid-range Logix controller. The current path is CompactLogix 5380 (5069-L3 series), programmed in Studio 5000. To avoid re-engineering an existing line, Edmundson Industrial sources new-surplus, used-tested, and reconditioned 1768 processors and 1769 I/O.

No. The 1768 L4x was superseded within the CompactLogix line by the 5370 and 5380 series. We source surplus 1768 processors and 1769 I/O to keep installed systems running, and quote the CompactLogix 5380 path when you plan to upgrade.
