Compactlogix l43 system overview
CompactLogix L43 System Overview

CompactLogix L43 System

  • A configurable system consisting of

    • 2Mb Controller (1768-L43)

    • Motion Module (1768-M04SE)

    • Ethernet Module (1768-ENBT)

    • Power Supply (1768-PA3)

    • Combination of any local 1769 I/O

      • Max 8 on local rack

      • Up to 16 modules and 3 racks

  • Configure the system to meet the applications requirements

    • Motion system solution might consist of the L43 with the ENBT & MO4SE modules

    • Non-motion system solution might have the L43 & two (2) ENBT modules

  • The L43 Motion system completely supports the Logix Integrated Motion Architecture including all 38 Logix Motion Instructions.

    • The ONLY difference between ControlLogix Motion and CompactLogix L43 motion is the number of AXIS

      • L43 supports applications with up to 4 axes

  • SIL Safety, Redundancy and Kinematics are not currently supported

Some typical applications
Some Typical Applications

  • Vertical Form Fill and Seal

  • Smart Belt

  • Rotary Knife

  • Cartoner

Vertical form fill and seal
Vertical Form Fill and Seal

Vertical Form Fill and Seal

  • Typical standard VFFS will consist of one or two axis on the film roll, one axis on the feed servo axis and one on the crimp servo axis = total 4 axis

  • High performance and specialty VFFS machines requiring higher axis counts would be better served with ControlLogix Motion

Smart belt
Smart Belt

  • Speed, accuracy and product characteristics usually determine how many correction belts are used

  • Typical non-high speed smart belts will utilize 2 to 4 belts. A perfect fit for the CompactLogix Motion Solution

  • In feed belts can use VF Drives to further minimize the number of servo axis

Rotary knife
Rotary Knife

  • CompactLogix 2 Aux Feedback support provides the ability to easily input web material speeds

  • Supported Logix CAM profile provides smooth speed transitions and exact speed synchronization when the knife contacts the material.

  • Typical applications requires 1 motor axis and 1 encoder Feedback Axis, perfect fit for CompactLogix


  • Absolute feedback enables the cartoner to maintain position, eliminates expensive and time-consuming homing routines.

  • Synchronization of multiple axes through gearing and camming.

  • Generate virtual axes to use as references for synchronizing real axes.

Frequently asked questions
Frequently Asked Questions

  • Does the new L43 controllers require a Battery?

NO!!! The L43 uses internal flash to store the program during shutdown. Energy stored in the power supply provides the few seconds of hold time required to store the entire RAM image on to onboard Flash.

This is onboard flash and is NOT the front accessible CompactFlash. The CompactFlash card is still optional and continues to function identical to CompactLogix L3x operation.

Frequently asked questions1
Frequently Asked Questions

  • What is this new 1768 Bus and how does it compare to the 1769 bus?

The L43 controller still uses the 1769 bus for Digital, Analog, and Specialty I/O. In addition, the L43 controller will support a new high performance bus -1768.

This new 1768 bus provides the performance to support Integrated SERCOS Motion and multiple NetLinx Networks.

The L43 controllers support bridging from one bus to the other, so data can still seamlessly pass between the two buses

Frequently asked questions2
Frequently Asked Questions

  • What products will be initially released?

The following products will be available at initial release, April 2006

- 1768-L43 Controller

- 1768-ENBT EtherNet/IP Module

- 1768-M04SE 4 Axis SERCOS Module

- 1768-PA3 AC Power Supply

Supported in RSLogix 5000 V15

Frequently asked questions3
Frequently Asked Questions

  • What other L4x products will follow?

The ControlNet Module will be released with v16 release

The DC Power Supply will be released July timeframe

Since the existing 1769-SDN will work with the new L4x controllers, there are NO plans to create a new Devicenet Module for the 1768 Bus

Frequently asked questions4
Frequently Asked Questions

  • How is the L4x positioned relative to other CompactLogix Controllers?

The L4x is positioned at the top end of the CompactLogix Family.

The new L4x will bring improved performance, added memory and network capacity, modularity, and Integrated SERCOS Motion to the CompactLogix Family.

These improved capabilities will result in a price premium over the other L3x CompactLogix Controllers.

Frequently asked questions5
Frequently Asked Questions

  • How is the L4x positioned relative to ControlLogix Controllers?

The 1768-L45 Controller is positioned below the ControlLogix 1769-L61 controller

The new L4x controllers will support less memory, less module expansion, and less Motion Axis than a ControlLogix system. ControlLogix is the exclusive platform for Redundancy, SIL2/SIL3 Safety, RIUP, Advanced I/O Diagnostics, and multiple Controllers per chassis.

The L4x rackless design and reduced functionality will result in a price savings over the more advanced ControlLogix System.

Frequently asked questions6
Frequently Asked Questions

  • What are the target applications for the L4x?

The CompactLogix L4x is a very powerful modular controller and is positioned at customers that value a system linked, architecture solution.

  • Applications that require 4 or less Axis of integrated motion

  • Applications that require a combination of NetLinx Networks

  • Cost sensitive applications which do not require the advanced features, or increased capacity of ControlLogix.

  • OEM and end user installations that require less cabinet real estate
