PLC-5 Controller Example 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 DeviceNet network (see
Figure 4.2 ). In our example, we
will configure a PLC-5 controller with 1771-SDN scanner to communicate
with a drive using Logic Command/Status, Reference/Feedback, and
Datalinks over the network.

Configuring Parameters for Network I/O
Because the I/O for the drive is defined in the next subsection Use
RSNetWorx for DeviceNet to Configure and Save the I/O to the
Controller on page 4-21
, there is no need to configure any I/O inside the
RSLogix 5 project, version 7.20 or later, until using the I/O as described in
Chapter 5 .
However, to get the adapter to operate with the I/O created in Chapter 5 , you
need to configure the adapter to accept the I/O and the drive to point to the
appropriate Datalinks.
1. Set adapter Parameters 13 - [DPI I/O Cfg], 25 - [M-S Input], and 26 -
[M-S Output] to values that meet your application requirements.
For this example, the adapter I/O parameters are set to these values.
2. Reset the adapter (see Resetting the Adapter on page 3-12 ), or power
cycle the drive.
The drive speed reference and Datalink parameter values, and the
adapter setup parameters for this example are shown below.
Adapter Parameter No. Setting
13 - [DPI I/O Cfg] xxxx xxxx xxx1 1111
25 - [M-S Input] xxxx xxxx xxx1 1111
26 - [M-S Output] xxxx xxxx xxx1 1111
