Module Data, Status, and Channel Configuration
Input Image
The input image file represents data words and status words. Input words
0 through 5 hold the input data that represents the value of the analog
inputs for channels 0 through 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 4-5.
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 B. For CompactLogix and RSLogix 5000, see Appendix C. For
1769-ADN DeviceNet Adapter and RSNetworx, see Appendix D.
Input Data File
The input data table allows you to access RTD input module read data for
use in the control program, via word and bit access. The data table
structure is shown in table below.
NOTE
Not all controllers support program access to the
configuration file. Refer to your controller’s user manual.
