Understanding the I/O Image

The terms input and output are defined from the scanner’s point of
view. Therefore, Output I/O is data that is output from the scanner
and consumed by the EtherNet/IP module. Input I/O is status data
that is produced by the module and consumed as input by the
scanner. The I/O image table will vary based on the:

Configuration of the Operating Mode Switch (SW1) on the module
and parameter 22 (MDI I/O Cfg). The image table always uses
consecutive words starting at word 0.
