A-B ControlLogix System Bulletin 1756 digital I/O modules

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.
