ControlLogix System Overview
The ControlLogix system provides discrete, drives, motion, process, and safety control together with communication and
state-of-the-art I/O in a small, cost-competitive package. The system is modular, so you can design, build, and modify it
efficiently with significant savings in training and engineering.
Example Configuration—ControlLogix System
A simple ControlLogix system consists of a standalone controller and I/O modules in one chassis. For a more comprehensive
system, use the following:
• Multiple controllers in one chassis
• Multiple controllers joined across networks
• I/O in multiple platforms that are distributed in many locations and connected over multiple I/O links

GuardLogix Safety System
A GuardLogix controller is a ControlLogix controller that also provides safety control. The GuardLogix system is a dual controller
solution—you must use a GuardLogix controller with the appropriate safety partner to achieve SIL 3/PLe/Cat. 4. A major benefit
of this system is that it is still one project, safety, and standard together. The safety partner controller is a part of the system, is
automatically configured, and requires no user setup.

ControlLogix I/O Modules
The ControlLogix architecture provides a wide range of input and output modules to span many applications, from high-speed
digital to process control. The ControlLogix architecture uses a Producer/Consumer model so that input information and output
status can be shared among multiple controllers.
Each ControlLogix I/O module mounts in a ControlLogix chassis and requires a removable terminal block (RTB) or a 1492
interface module (IFM) to connect all field-side wiring. RTBs and IFMs are not included with the I/O modules. They must be
ordered separately.
For detailed specifications, see 1756 ControlLogix I/O Modules Specifications Technical Data, publication 1756-TD002.

1756 Removable Terminal Blocks
Removable terminal blocks (RTBs) provide a flexible interconnection between your plant wiring and
1756 I/O modules. The RTB plugs into the front of the I/O module. The type of module determines the
RTB you need. You can choose screw-clamp or spring-clamp RTBs.
RTBs are not shipped with I/O modules. You must order them separately. The standard housing on the
front of the wiring arm is not necessarily deep enough for 2.5 mm2 (14 AWG) wiring. If you plan to use
2.5 mm2 (14 AWG) wiring, also order the extended housing. For more information on Extended-Depth
Housing, see Rockwell Automation Knowledgebase article #41488, Use of the 1756-TBE Extended
Terminal Housing. You can access the article at: https://rockwellautomation.custhelp.com/ (login is required).

Wiring Systems
As an alternative to buying RTBs and connecting the wires yourself, you can buy a wiring system of
the following:
• Interface modules (IFMs) that provide the I/O terminal blocks for Digital I/O modules. Use the
prewired cables that match the I/O module to the IFM.
• Analog interface modules (AIFMs) that provide the I/O terminal blocks for analog I/O modules.
Use the prewired 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.

Consideration
USB connection
The ControlLogix controllers have a USB port in place of the serial port.(1) If your application requires RS-232 functionality, see the many Encompass
Partners’ products at http://www.rockwellautomation.com/encompass.
DH-485 network
The controller serial port is compatible with DH-485 communication. The DH-485 connection does support remote programming and monitoring via the
Logix Designer application.
Or, add a 1756-DH485 communication module.
SynchLink™ network
The SynchLink communication module (1756-SYNCH) provides time synchronization and data broadcasting capabilities for distributed motion and
coordinated drive control. The module connects a ControlLogix chassis to a SynchLink fiber-optic communication link.
(1) The USB port is intended only for temporary local programming purposes and not intended for permanent connection. Do not use the USB port in hazardous locations.
Modbus Support
To access a Modbus TCP network, connect through the embedded Ethernet port of the CompactLogix 5370 controllers and
execute a ladder-logic routine. For more information, see Knowledgebase document 470365 at
http://www.rockwellautomation.com/knowledgebase/.
To access a Modbus RTU network, connect through the serial port (if available) and execute a ladder-logic routine. For more
information, see Using Logix5000™ Controllers as Masters or Slaves on Modbus Application Solution, publication CIG-AP129.

ControlLogix Controllers
The ControlLogix controller provides a scalable controller solution capable of addressing many I/O points.
The controller can be placed into any slot of a ControlLogix chassis and multiple controllers can be installed in the same chassis.
Multiple controllers in the same chassis communicate with each other over the backplane (just as controllers can communicate
over networks) but operate independently.
ControlLogix controllers can monitor and control I/O across the ControlLogix backplane, and over I/O links. ControlLogix
controllers can communicate over EtherNet/IP, ControlNet, DeviceNet, DH+, Remote I/O, and RS-232-C (DF1/DH-485 protocol)
networks and many third-party process and device networks. To provide communication for a ControlLogix controller, install
the appropriate communication interface module into the chassis.

ControlLogix-XT Controllers
The ControlLogix-XT controllers function in the same way as the traditional ControlLogix controllers, with an
extended temperature range, and have the same features as the ControlLogix L7 controllers.
The ControlLogix-XT products include control and communication system components that are
conformally coated to extend product life in harsh, corrosive environments:
• While the standard ControlLogix system can withstand temperatures from 0…60 °C (33…140 °F), the
ControlLogix-XT system can withstand temperatures from 25…70 °C (-13…158 °F).
Redundant ControlLogix Controllers
The ControlLogix controller supports controller redundancy. In a redundant controller system, you need these components:
• Two 1756 chassis each with the following the same:
– Number of slots
– Modules in the same slots
– Redundancy firmware revisions in each module
– Two additional ControlNet nodes(1) outside the redundant chassis pair.
• One 1756-RM2 or 1756-RM2XT module per chassis that supports the following:
– One or two ControlLogix or ControlLogix-XT controllers of the same family
– As many as seven ControlNet or EtherNet/IP communication modules in any combination
• One or two 1756-RMCx cables
For additional redundancy rules and restrictions, see the ControlLogix Enhanced Redundancy System User Manual,
publication 1756-UM535.
(1) For a ControlNet I/O drop, two more ControlNet nodes are required outside the redundancy chassis pair. Not applicable with Ethernet I/O control.

GuardLogix Controllers
A GuardLogix controller is a ControlLogix controller that also provides safety control.
Application
Description
SIL 1, 2, 3
The 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 the following:
• GuardLogix 5570 Controllers User Manual, publication 1756-UM022. Provides information on how to install, configure, and operate
GuardLogix 5570 Controllers in Studio 5000, Version 21 or later projects.
• GuardLogix 5570 Controller Systems Safety Reference Manual, publication 1756-RM099. Provides information on how to meet safety
application requirements for GuardLogix 5570 Controllers in Studio 5000, Version 21 or later projects.
The GuardLogix system is a dual controller solution. You must use a primary controller and a
safety partner to achieve SIL 3/PLe/Cat. 4.

1756-L7SP
1756-L73SXT
1756-L7SPXT
During development, safety and standard have the same rules, multiple programmers, online
editing, and forcing are all allowed. Once the project is tested and ready for final validation, you set the Safety Task to a SIL 3
integrity level, which the GuardLogix controller enforces. When safety memory is locked and protected, the safety logic cannot
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.
Use Guard I/O™ modules for field device connectivity on Ethernet or DeviceNet networks, and 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 different cells/areas.
The GuardLogix controller has the standard features of a ControlLogix controller and these safety-related features.
