The EDS files for OMRON EtherNet/IP slaves are already installed in the Sysmac Studio and Network 
Configurator.
You can update the Sysmac Studio, CX-One, or from OMRON websites to get the ESI files for the most 
recent models.
Unit power supplies provide power for communications and the internal operation of EtherNet/IP Slave 
Term i nals .
I/O power supplies provide power for the I/O operation of the external devices that are connected to 
EtherNet/IP Slave Terminals.
There are several types of Support Software for network configuration. They are used as follows 
depending on the purpose.
When using an EtherNet/IP Unit as the EtherNet/IP master, use the CPU Unit configuration software 
(such as the Sysmac Studio or CX-Programmer) to set the basic settings, such as the IP address and 
subnet mask of the EtherNet/IP Unit. 
You can also use the CPU Unit configuration software to check data I/O for tag data links to see if they 
are performed normally.
