6. Use the procedure in the subsection Use RSNetworx for ControlNet
Software to Save the I/O to the Bridge on page 4-13 to:
– Change the I/O Not Responding box in the upper-left of the
RSLogix 5000 window from flashing green to steady green.
– Remove the yellow warning symbols in the treeview under the I/O
Configuration folder and drive profile.
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 ControlNet network (see
Figure 4.5 ). In our example, we
will configure a PLC-5/40C controller 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 ControlNet Software to Configure the I/O and Save It to the
Controller on page 4-25
, there is no need to configure any I/O inside the
RSLogix 5 project, version 7.00 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.
