3-2 Module Data, Status, and Channel Configuration for the Input Module

1769-IF4I Input Image

The 1769-IF4I input image file represents data words and status bits. Input

words 0 to 3 hold the input data that represents the value of the analog inputs

for channels 0 to 3. These data words are valid only when the channel is

enabled and there are no errors. Input words 5 and 6 hold the status bits. To

receive valid status information, the channel must be enabled.

1769-IF4I Output Image

The 1769-IF4I output image file contains the clear alarm control bits for the

high- and low-alarm bits on each input channel. These bits are used to clear

alarms when alarms are latched.

1769-IF4I Configuration File

The configuration file contains information that you use to define the way a

specific channel functions.

The configuration file is explained in more detail in 1769-IF4I Configuration

Data File on page 3-6.

TIP

You can access information in the input image file using

the programming software configuration screen.
