ControlLogix Digital I/O Modules

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.

ControlLogix® digital I/O modules are input and output modules that provide

On/Off detection and actuation. By using the producer/consumer network

model, digital I/O modules can produce information when needed while

providing additional system functions.

I/O modules in a ControlLogix system can be owned by a Logix5000™

controller. An owner-controller fulfills these functions:

• Stores configuration data for every module that it owns

• Sends I/O modules configuration data to define module behavior and

begin module operation with the control system

• Resides in a local or remote chassis in regard to the I/O module position

Each ControlLogix I/O module must continuously maintain communication

with its owner-controller to operate normally.

Typically, each module in the system has only one owner-controller. Input

modules can have more than one owner-controller. Output modules, however,

are limited to a single owner-controller.

ControlLogix modules mount in a ControlLogix chassis and require either a

removable terminal block (RTB) or a Bulletin 1492 wiring interface module

(IFM)(1) to connect all field-side wiring.

Before you install and use your module, you must do the following:

• Install and ground a 1756 chassis and power supply. To install these

products, refer to the publications listed in 

• Order and receive an RTB or IFM and its components for your

application.
