Chapter 4 Module Data, Status, and Channel Configuration
Input Image
The input image file represents data words and status words. Input words 0…5
hold the input data that represents the value of the analog inputs for channels
0…5. These data words are valid only when the channel is enabled and there
are no errors. Input words 6 and 7 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 50.
Accessing Input Image File
Data Eight 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 1500 and RSLogix 500, see Appendix A. For
CompactLogix and RSLogix 5000, see Appendix B. For 1769-ADN
DeviceNet Adapter and RSNetworx, see Appendix C.
TIP Not all controllers support program access to the
configuration file. Refer to your controller’s user manual.
