This chapter explains how the Weigh Scale module and the processor communicate
through the module's input and output image.
For CompactLogix / RSLogix™ 5000 setup, please refer to Appendix A
With RS Logix500 software, verify the module ID code.

No special I/O configuration (SPIO CONFIG) information is required. The module ID code
automatically assigns the correct number of input and output words. The following memory map
shows how the output and input image tables are defined.
The 8 word output image (output from the CPU to the module) contains
Information that you configure to define the way a specific channel will work.
Output Image
Example – If you want to configure channel 2 on the module located in slot 4
in the SLC chassis, your address would be O:4.2.
