Modular ESI files
An ESI file involves a device description file that is made available to the EtherCAT master, i.e. a controller, for the
configuration of the EtherCAT network. Each controller accepts a maximum of one ESI file per drive controllers series for
configuring the corresponding EtherCAT network.
In order to guarantee maximum flexibility regarding PDO transmission options, STOBER ESI files have a modular structure.
A STOBER ESI file contains specified configurations for PDO transmission for every application in the form of default
modules. You can add to the standard configurations of any application or configured PDO transmission freely as desired
and add your STOBER ESI file as a new module. The number of expandable modules is unlimited.
