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.
