Understanding the I/O Image The CANopen specification requires that the terms input and output be
defined from CANopen network’s point of view. Therefore, Output I/O is
data that is output from the CANopen network and consumed by the
CANopen adapter. Input I/O is status data that is produced by the adapter
and consumed as input by the CANopen network. The I/O image table will
vary based on:
•
Size (either 16-bit or 32-bit) of the Reference/Feedback words and
Datalink words used by the drive. To determine the size of the
Reference/Feedback and Datalinks, view adapter Parameters 07 - [Ref/
Fdbk Size] and 08 - [Datalink Size]. For information to access
parameters, see
•
Configuration of I/O (Parameter 12 - [DPI I/O Config]) in the adapter.
If any I/O is not enabled, the image table is truncated. The image table
always uses consecutive words starting at word 0.
The controller I/O image changes depending on the size of the drive’s
Reference/Feedback and Datalinks.
Table 5.C , Table 5.D , and Table 5.E
show the I/O image when using various PowerFlex 7-Class drives.
