8.3 Understanding the I/O Image
The DeviceNet specification requires that the terms input and
output be defined from the scanner’s point of view. Therefore,
Output I/O is data that is output from the scanner and consumed by
the DeviceNet 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 Mode Jumper (J2) on the module and
parameter 15 (DSI I/O Cfg). The image table always uses
consecutive words starting at word 0.
Figure 8.5 illustrates the Multi-Drive I/O image with 16-bit words.
