EtherNet/IP is an Ethernet-based fieldbus. EtherNet/IP was developed by Allen-Bradley (Rockwell Automation) and later transferred to the Open DeviceNet Vendor Association (ODVA) as an open standard. In 1998, a working group at ControlNet International developed a procedure for setting the published Common Industrial Protocol to Ethernet. EtherNet/IP was published in March 2000 as an open industrial automation standard based on this procedure.

This bus controller makes it possible to connect X2X Link I/O nodes to EtherNet/IP. The bus controller can be operated via interface module X20IF10D1-1 or by 3rd-party systems with EtherNet/IP scanner functionality.

Additional X2X Link I/O nodes (X67 modules or other modules based on X2X Link) can be connected using the integrated X2X Link connection.

Only the standard function model (see the respective module description) is supported when the bus controller is used together with multi-function modules it has automatically configured itself.

Automation Studio V4.3 or later can be used to easily create configuration files (e.g. EDS files, binary files). All other function models are also supported by transferring configuration data to the bus controller (e.g. using the scanner via a "configuration assembly").

Automation Studio can be downloaded at no cost from the B&R website (www.br-automation.com). The evaluation license is permitted to be used to create complete configurations for fieldbus bus controllers at no cost.
