ETHERNET/IP TARGET
A controller (e.g. Logix controller) can own the ControlNet Router over EtherNet/IP using a
Class 1 EtherNet/IP connection when the ControlNet Router is operating as an EtherNet/IP
target. This will allow the ControlNet Router to exchange data with the controller using the
input and output assembly of the Class 1 EtherNet/IP connection.

ONNECTION
When the module uses EtherNet/IP (as a Target) the Logix controller will establish a cyclic
Class 1 EtherNet/IP communication connection with the ControlNet Router. An input and
output assembly is exchanged at a fix interval (RPI). The UDTs provided will convert the input
and output arrays into tag-based assemblies. Refer to the additional information section in
this document for the input and output UDTs.
