Understanding the I/O Image
The terms input and output are defined from the controller’s point of
view. Therefore, output I/O is data that is produced by the controller and
consumed by the adapter. Input I/O is status data that is produced by the
adapter and consumed as input by the controller. The I/O image will
vary based on:
•
How many of the drive’s 32-bit Datalinks (DL From Net 01-16 and
DL To Net 01-16) are used.
•
ControlLogix Controllers only — Specific drive profile used in
RSLogix 5000 (Add-On Drive Profile in v16 or higher or Generic
Profile in all versions of RSLogix 5000).
ControlLogix Controller Image
Since the Add-On Drive Profile in RSLogix 5000 (v16 or higher)
provides descriptive controller tags, the I/O image (tag size and
location) is automatically configured based on the drive being used.
When using the Generic Profile in RSLogix 5000, however, controller
tags are not descriptive or defined.
shows the I/O image when using all of the 32-bit Datalinks.

This is only required when the Generic Profile is used. The Add-On Profile automatically accounts
for this and, therefore, hides the Pad in the I/O input image.
