Example Network
After the adapter is configured, the connected drive and adapter will be
a single node on the network. This section provides the steps needed to
configure a simple EtherNet/IP network (see
). In our
example, we will configure a SLC 500 controller to communicate with
a drive using Logic Command/Status, Reference/Feedback, and 32
Datalinks (16 to read/16 to write) over the network.

Configuring Parameters for Network I/O
Since the I/O for the drive is message-based, there is no need to
configure any I/O inside the RSLogix 500 (v7 or higher) project until
using the I/O as described in
.
However, to get the adapter to operate with the I/O created in
,
we need to configure the adapter to accept the I/O and drive to point to
the appropriate Datalinks.
Since the adapter always uses the 32-bit Logic Status and 32-bit
Feedback, at least two 32-bit words must be accounted for in the
controller input image. The adapter also uses the 32-bit Logic
Command and 32-bit Reference, requiring at least two 32-bit words that
must be accounted for in the controller output image. If any or all of the
drive’s sixteen 32-bit Datalinks are used (see
Custom Peer I/O Configuration on
•
An additional 32-bit word for each [DL From Net xx] Datalink used
to write to drive or peripheral parameters must be accounted for in
the controller input image.
•
An additional 32-bit word for each [DL To Net xx] Datalink used to
read data must be accounted for in the controller output image.
