3-2 Module Data, Status, and Channel Configuration

Input Image

The input image file represents data words and status words. Input
words 0 through 3 hold the input data that represents the value of the
analog inputs for channels 0 through 3. These data words are valid
only when the channel is enabled and there are no errors. Input
words 4 and 5 hold the status bits. To receive valid status information,
the channel must be enabled.

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 Configuration Data File on page 3-6.

Accessing Input Image File
Data

Six words of the processor input image table are reserved for the
module’s image data. You can access the information in the input
image file using the programming software configuration screen. For
more information on configuration using MicroLogix 1200 and
RSLogix 500, see Appendix B.

TIP

Not all controllers support program access to the
configuration file. Refer to your controller’s user
manual.
