The performance of a CompactLogix controller on a ControlNet network degrades significantly if you use the
controller as a bridge. Target bridging over a CompactLogix controller on a ControlNet network toward
applications that are not real-time dependent, such as Logix Designer software program downloads.
In the example shown above, you can transfer messages from the DeviceNet
network through the Logix 5000 controller to an RSView32 operator
interface. With a CompactLogix controller as a bridge, you can map the data
into the DeviceNet I/O image and then use RSLinx OPC to send the data to
the Logix 5000 controller over the ControlNet network. This method
conserves the limited bridging resources of your CompactLogix controller.
The following example shows how a DeviceNet bridge links to an
EtherNet/IP network in RSLinx Classic software.

The following tables list the possible bridges between communication
networks. Note that you can bridge from a ControlNet network to an Ethernet
network and from an Ethernet network to a ControlNet via a SoftLogix
virtual chassis. However, the products and methods you must use to do so are
more detailed than can be effectively described in the following tables. For
