Using the I/O
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 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 16-bit Datalinks (
Host parameters C161 [Opt
Data In 1]
through C164 [Opt Data In 4] and C165 [Opt Data Out 1]
through C168 [Opt Data Out 4]) are used.
Device parameters 02 [DLs From Net Act] and 03 [DLs To Net Act]
must also be configured accordingly if Datalinks are used.
• ControlLogix/CompactLogix Controllers only
—The drive Add-On
Profile (AOP) used in RSLogix 5000 (version 17 or greater) or Logix
Designer (version 21 or greater) software, or the Generic Profile (all
versions).
•
If Multi-drive mode is enabled, and the number of daisy-chained drives
that are present.
I/O Controller Image
Since the drive Add-On Profile in RSLogix 5000 (version 17 or greater) and
Logix Designer (version 21 or greater) software 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 or Logix
Designer, however, controller tags are not descriptive.
I/O Image for PowerFlex 525 Drives on page 64
shows the I/O image when using
all of the 16-bit Datalinks.
I/O Image for PowerFlex 525 Drives
(16-bit Logic Command/Status, Reference/Feedback, and Datalinks)
Single drive mode is the typical configuration, where one node consists of a
PowerFlex 520-series drive with a 25-COMM-E2P adapter.
For Multi-Drive mode, where one node can consist of up to five drives, see
