Communication with the Code Reader over EtherNet/IP Connec
tion
You can use an EtherNet/IP Tag Data Link to communicate between the PLC and the code reader.
The PLC can control the code reader with Command/Response communications and the code reader
can output data after executing a Read.
To connect to OMRON Controllers and communicate through EtherNet/IP, you can use Sysmac Stu-
dio, or Network Configurator to set up the Tag Data Links (tags, tag sets, and connection settings).
For more detailed information on Tag Data Link settings, please refer to the following manuals.

Types of Communication Areas
For EtherNet/IP, communication with a PLC, the communication is performed using two
communication areas on the PLC, the Input Field and the Output Field. The
V430-F
has 6 types of
Input Field Assemblies and 2 types of Output Field Assemblies, and one can be selected for each.
