How to Import the ESI File into a Non-Delta Controller

The EtherCAT motion control fieldbus is an open standard that uses an ESI (EtherCAT Slave Information) file to configure the functions and associated object properties of each slave.
An ESI file is typically a standard XML file.

Integration with non-Delta controllers

Import the ESI file from the slave device into the controller software.
This allows the controller to recognize the device and control it according to the configuration in the ESI file.

An ESI file can contain data from multiple devices.

Download the ESI file from the article on our website.

After importing into the controller software, the ESI file is usually saved in the following locations (this may vary):

Beckhoff TwinCAT

• TwinCAT 2: C:\TwinCAT\IO\EtherCAT
• TwinCAT 3: C:\TwinCAT\3.1\Config\Io\EtherCAT

Omron Sysmac Studio

• C:\Program Files (x86)\OMRON\Sysmac Studio\IODeviceProfiles\EsiFiles\UserEsiFiles
