ETHERNET/IP ORIGINATOR
The ControlNet Router module can operate as an EtherNet/IP originator. In this mode the
module can exchange data from the ControlNet network with EtherNet/IP devices using
either the input and output assemblies of the Class 1 EtherNet/IP connection to the device or
using explicit (Class 3 or UCMM) EtherNet/IP messages.

ONNECTIONS
In the example below, the ControlNet Router is owned by a Logix controller over ControlNet
while the ControlNet Router is owning some EtherNet/IP IO. The data from the Logix
controller is exchanged with those of the EtherNet/IP IO.
Once the EtherNet/IP Class 1 connections are setup and established then any Internal Map
copying to an EtherNet/IP device will be written to the output assembly of the selected
EtherNet/IP device (Originator to Target). In the Internal Map the user will specify which
device instance is the target and at what offset the data must be written in the output
assembly.
