ControlLogix Controllers Overview

Click to enlarge - 1756-L65 Ctrl Lgx in Chassi_ BW


The ControlLogix controller provides a scalable controller solution that is capable of addressing a large amount of I/O points.

The controller can be placed into any slot of a ControlLogix I/O 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, as well as over I/O links. ControlLogix controllers can communicate over EtherNet/IP, ControlNet, DeviceNet, DH+, Universal 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.


Available controllers include: ControlLogix controllers, GuardLogix safety controllers, and ControlLogix -XT extreme environment controllers.

ControlLogix-XT controllers function in the same way as the standard ControlLogix controllers. ControlLogix-XT products also include control and communication system components that, when used with FLEX I/O-XT products, provide a complete control system solution that can be used in environments where temperatures range from ‑20...70 °C (‑4...158 °F).

When used independently, a ControlLogix-XT system can withstand environments where the temperature ranges from ‑25...70 °C (‑13...158 °F).

GuardLogix Controllers

Click to enlarge - GuardLogix_in_chassis_GS


A GuardLogix controller is a ControlLogix processor that also provides safety control. The GuardLogix system is a dual processor solution — you must use a GuardLogix L6 controller with a 1756-LSP safety partner or a GuardLogix L7 controller with a 1756-L7SP safety partner to Achieve SIL 3 and Cat. 4/PLe. A major benefit of this system is that it is still a single project, safety and standard together. The safety partner is a part of the system, is automatically configured, and requires no user setup.

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 is then 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 allowed.


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 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 a single GuardLogix controller can use remote distributed safety I/O between different cells/areas.

For additional information see Safety Programmable Controllers, GuardLogix Integrated Safety System.

Accessories—Controllers

Memory Cards

Memory cards offer nonvolatile memory to permanently store a user program and tag data on a controller. The ControlLogix 5570 controllers come with a 1784-SD1 Secure Digital card already installed. ControlLogix 5560 controllers support an optional CompactFlash card purchased separately. Through RSLogix 5000 software, you can manually trigger the controller to save to or load from nonvolatile memory or configure the controller to load from nonvolatile memory on powerup.

1756 Energy Storage Modules

Instead of a battery, ControlLogix 5570 controllers ship with a 1756-ESMCAP energy storage module (ESM) already installed. The ESM eliminates the need for a battery.

Attribute 1756-ESMCAP 1756-ESMNSE 1756-ESMNRM
Description Capacitor-based Energy Storage Module Energy storage module without WallClockTime back-up power Nonremovable capacitor-based energy storage module
Use Ships with the controller Use this ESM if your application requires that the installed ESM deplete its residual energy to 200 mJoule or less before transporting it into or out of your application. Additionally, you can use this ESM with a 1756-L73 (8 MB) or smaller memory-sized controller only. Secures the controller by preventing the USB connection and access to SD card removal. If the SD card is installed prior to insertion of the 1756-ESMNRM module, the SD card
remains functional, but not removable.
Supported controllers ControlLogix 5570 controllers

Replacement Batteries

Each ControlLogix 5560 controller ships with a battery. The controller can be used without a battery if you install a 1784-CF128 industrial CompactFlash card. Without a battery, current tag data will be at the state it was when the nonvolatile memory was saved.

The 1756-BATM includes one 1756-BATA lithium battery assembly and a 1 m (3.28 ft) cable to connect housing to controller.
‡ The 1756-L55M22, 1756-L55M23, and 1756-L55M24 controllers have nonvolatile memory and can be used without a battery.
