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.

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

• Select ControlLogix products are available with a conformal coating that adds a layer of protection when exposed to harsh, corrosive

environments. Products with a conformal coating have a ‘K’ suffix at the end of the catalog number.

The ControlLogix controller is part of the Logix 5000™ family of controllers.

• 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.

• 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.

• To provide communication for a ControlLogix 5570 controller, install the appropriate communication interface module into the

chassis. ControlLogix 5580 controllers have a built-in EtherNet/IP port.
