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 option module. Input I/O is status data that is produced by the option
module and consumed as input by the controller. The I/O image will vary based
on the following:
•
How many of the drive’s 32-bit Datalinks (
Host DL From Net 01-16 and
Host DL To Net 01-16) are used.
• ControlLogix/CompactLogix Controllers only
—The drive profile used
in RSLogix 5000 software (drive Add-on Profile in version 16.00 or later,
or Generic Profile in all versions).
ControlLogix Controller Image
Since the drive Add-on Profile in RSLogix 5000 software, version 16.00 or later,
provides descriptive controller tags, the I/O image (tag size and location) is
automatically configured based on the drive being used. When using the RSLogix
5000 Generic Profile, however, controller tags are not descriptive or defined.
shows the I/O image when using all of the 32-bit Datalinks.
