About the Logix5000 ControlNet Communication Modules 1-9
Bridge Across Networks
Some ControlNet modules support the ability to bridge or route
communication to and from different networks, depending on the capabilities
of the platform and communication devices.
With unscheduled communication, you have a bridge when you have a
connection between communication devices on two separate networks. For
example, the bridge device shown below has both ControlNet and DeviceNet
connections so that Device 1 on ControlNet can communicate with Device 2
on DeviceNet through the bridge.
Communication can bridge these networks:.

To use RSNetWorx software to configure and schedule a ControlNet network, we recommend that you either: connect to an EtherNet/IP network and
bridge to a ControlNet network or use a 1784-PCC interface device to connect directly to a ControlNet network.

Typically, this is a point-to-point connection between a Logix5000 controller and another device, such as a PanelView™ Plus operator terminal.
