EtherCAT Slave Information Files (ESI Files)

The setting information for an EtherCAT slave is provided as ESI file (EtherCAT Slave Information).
In EtherCAT, its various communication settings are defined based on the ESI definition information
and the network connection information for the connected slaves.
Installing ESI files into the network setup software (configuration tool) can generate the network con-
figuration information.
Downloading the generated network configuration information to the EtherCAT master enables you to
setup the EtherCAT network.
ESI files
ESI files for the FH/FHV can be downloaded from the OMRON website.
*1: If you are using Sysmac Studio, it is not necessary to install the ESI files in the network setup soft-
ware (configuration tool). The ESI files for OMRON EtherCAT slaves have already installed in the Sys-
mac Studio. Auto-update function in the Sysmac Studio enables you to get the ESI files for the latest
models.
