# EtherNet/IP PLC Configuration

Cognex Designer supports EtherNet/IP, an application level protocol based on the Common Industrial Protocol (CIP).

EtherNet/IP provides an extensive range of messaging options and services for the transfer of data and I/O over Ethernet. All devices on an EtherNet/IP network present their data to the network as a series of data values called attributes. Attributes can be grouped with other related data values into sets, these are called Assemblies.

Enabling EtherNet/IP involves the following main steps:

1. Make sure you have the Rockwell Software tool on your machine.
2. Set up the Rockwell Software tool so that it recognizes your vision system.

3. Install the Electronic Data Sheets (EDS) for the Cognex Communication Card and the Cognex Vision Controller.

   Go to: Programs->Rockwell Software-> RSLinx->Tools->EDS Hardware Install Tool.

   The EDS files are located at: C:\Program Files\Cognex\VisionPro\ffp\eds.

Note: The C:\Program Files\Cognex\VisionPro\ffp\eds directory also includes a rung file that describes the layout of the input and output assemblies.
