Chapter 5 Using the I/O
Understanding the
ControlLogix Controller 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).
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.
Table 2 shows the I/O image when using all of the 32-bit Datalinks.
