ALLEN-BRADLRY ControlLogix Digital I/O Modules 1756 输入输出模块

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.
