CompactLogix Controllers Overview
The CompactLogix system is designed to provide a Logix solution for small and mid-size applications. Typically, these
applications are machine-level control applications. A simple system can consist of a standalone controller with one bank of I/O
modules and DeviceNet communication. In a more complex system, add other networks, motion control, and safety control. As
part of the Integrated Architecture™ system, the CompactLogix controllers use the same programming software, network
protocol, and information capabilities as all Logix controllers, providing a common development environment for all control
disciplines.
• The CompactLogix 5370 L3 controllers deliver scalable, affordable control ideal for applications from small standalone
equipment to high-performance indexing tables, process skids, case packers and erectors, and packaging. The
CompactLogix 5370 L3 controllers also provide a truly integrated motion solution.
• The CompactLogix 5370 L2 controllers combine the power of the Logix architecture with the flexibility of Compact I/O
modules. From small standalone equipment to higher performance applications, these controllers are ideal for assembly
machines, hoisting systems, process skids, indexing tables, and packaging.
• The CompactLogix 5370 L1 controllers combine the power of the Logix architecture with the flexibility of POINT I/O. Ideal
for small to mid-size machines, these controllers offer value to customers looking for the benefits of Integrated
Architecture in a lower cost system.

CompactLogix Controllers
The CompactLogix platform brings together the benefits of the
Logix platform— common programming environment,
common networks, common control engine—in a small
footprint with high performance. Combined with Compact I/O
modules, the CompactLogix platform is perfect for tackling
smaller, machine-level control applications, with or without
simple motion, with unprecedented power and scalability. A
CompactLogix platform is ideal for systems that require
standalone and system-connected control over EtherNet/IP,
ControlNet, or DeviceNet networks.

(1) IMPORTANT: Typically, you can use any of the new controllers listed in each row as replacements for any of the previous controllers listed in the corresponding cell to the right. For example, you can replace a 1769-L32E with
a 1769-L30ER, 1769-L30ERM, or 1769-L30ER-NSE controller.
In some rare cases, system configuration prevents controller replacement as shown above. For example, if your system uses a 1769-L32E controller with 12 expansion modules, you cannot replace that controller with a
1769-L30ER, 1769-L30ERM, or 1769-L30ER-NSE controller. Those controllers support no more than 8 expansion modules. You must replace the 1769-L32E controller with a 1769-L33ER, 1769-L33ERM, or
1769-L36ERM controller.
We recommend that before you upgrade your controllers, consider your application requirements to verify that the replacements listed above apply.

ControlNet Communication Options for 1768 CompactLogix Controllers
The ControlNet network is an open, control network for real-time, high-throughput applications. The ControlNet network uses
the Common Industrial Protocol (CIP) to combine the functionality of an I/O network and a peer-to-peer network providing
high-speed performance. The ControlNet network gives you deterministic, repeatable transfers of all mission-critical control
data and supporting transfers of non-time-critical data. I/O updates and controller-to-controller interlocking take precedence
over program uploads and downloads and messaging.

Compact GuardLogix Integrated Safety
The Compact GuardLogix controller is a 1768-L4xS CompactLogix controller that provides safety control to achieve SIL 3/PLe
according to ISO 13849. A major benefit of this system is that it is still one project, safety and standard together.
Application
Description
SIL 1, 2, 3
The Compact GuardLogix controller system is type-approved and certified for use in safety applications up to and including SIL 3 according to IEC 61508, and
applications up to and including PLe/Cat.4 according to ISO 13849-1. For more information, see:
• GuardLogix Controllers Systems Safety Reference Manual, publication 1756-RM093.
• Compact GuardLogix Controllers User Manual, publication 1768-UM002.
• GuardLogix Safety Application Instruction Set Reference Manual, publication 1756-RM095.
During development, safety and standard have the same rules, multiple programmers, online editing, and forcing are all
possible. Once the project is tested and ready for final validation, you apply the safety application signature and safety-lock the
application to set the safety task to a SIL 3 integrity level, which is enforced by the GuardLogix® controller. When safety memory
is locked and protected, the safety logic can't be modified and all safety functions operate with SIL 3 integrity. On the standard
side of the GuardLogix controller, all functions operate like a regular Logix controller. Thus online editing, forcing, and other
activities are all possible.
With this level of integration, safety memory can be read by standard logic and external devices, like HMIs or other controllers,
eliminating the need to condition safety memory for use elsewhere. The result is easy system-wide integration and the ability to
display safety status on displays or marquees. Use Guard I/O modules for field device connectivity. For safety interlocking
between GuardLogix controllers use Ethernet or ControlNet networks. Multiple GuardLogix controllers can share safety data for
zone to zone interlocking, or one GuardLogix controller can use remote distributed safety I/O between cells/areas.
The Compact GuardLogix controller has these safety-related features and the standard features of a CompactLogix controller.

family is ideal for applications where flexibility and
low-cost of ownership are key for successful control
system design and operation.
The base (A) mounts onto the DIN rail and provides
the backplane. The POINT I/O module (B) snaps into
the base. The removable terminal block (C) also
snaps into the base and provides the wiring and

As an alternative to buying removable terminal blocks (RTBs) and connecting the wires yourself, you can buy a wiring system of:
• interface modules (IFMs) that provide the output terminal blocks for digital I/O modules. Use the pre-wired cables that
match the I/O module to the IFM.
• analog interface modules (AIFMs) that provide the output terminal blocks for analog I/O modules. Use the pre-wired
cables that match the I/O module to the AIFM.
• I/O module-ready cables. One end of the cable assembly is an RTB that plugs into the front of the I/O module. The other
end has individually color-coded conductors that connect to a standard terminal block.
