Ethercat Slave Information Files (Esi Files) - Omron NX-ECC201 User Manual

8-2 EtherCAT Slave Information Files
(ESI Files)
The setting information for an EtherCAT slave is provided in an ESI file (EtherCAT slave information).
The EtherCAT communications settings are defined based on the ESI files of the connected slaves and
the network connection information.
You can create the network configuration information by installing ESI files into the network setup soft-
ware (configuration tool).
You can download the network configuration information to the EtherCAT master to configure the Ether-
CAT network.
ESI files
ESI files for the EtherCAT Coupler Unit and NX Units can be downloaded from the OMRON website.
*1. Installation of the ESI files is not necessary if you are using the Sysmac Studio. The ESI files for OMRON
EtherCAT slaves are already installed in the Sysmac Studio. You can update the Sysmac Studio to get the
ESI files for the most recent models.
