Learning RSLogix 5000 Programming
By :
In 2006, Rockwell Automation first shipped the (bulletin 1768) L43 CompactLogix controllers targeted at cost effective, small- to medium-size automation solutions. At the time of launch, CompactLogix controller was planned as the long-term replacement for the SLC 500 controller family. The CompactLogix control platform is designed with an emphasis on the controller software. As the CompactLogix hardware evolves with an improved performance and additional features, the logic will easily migrate to new hardware and firmware versions. Unlike the SLC 500 platform, the CompactLogix controllers can be programmed using the same RSLogix 5000 (Logix Designer) software suite that is used with ControlLogix. In 2006, CompactLogix L43 with integrated motion support was added to the family. It features a CompactFlash memory card, Ethernet port, Serial RS-232 port, 1769 / 1768 modules, and a power supply module. The following is an illustration of the L43 CompactLogix controller:

Modules on L43 can only be placed to the right of the power supply.
In 2008, Rockwell Automation released the low-cost CompactLogix L23 controllers (bulletin 1769) with embedded I/O. The L23 controller features a serial RS-232 port, Ethernet port (only on the E models), embedded I/O, and an embedded power supply. The following is an illustration of an L23 controller:

Also in 2008, Rockwell Automation released the (bulletin 1769) CompactLogix L3x modular controllers. The 1769 CompactLogix modules do not have a chassis like the ControlLogix modules. The 1769 CompactLogix modules can be connected together using a DIN rail or can be screwed in directly to a panel. CompactLogix L3x features a CompactFlash memory card, serial RS-232, ControlNet or Ethernet port, and a power supply module. The following diagram is an illustration of the CompactLogix L3x controller:

The L3x modules can be placed to the left or the right of the power supply.
In 2009, Compact GuardLogix, an SIL3 certified controller, with the L43S and L45S CPU supporting integrated safety, was added to the Logix family.
