ESI file extension - EtherCAT slave information

What is esi file? How to open esi files?

File type specification:

Configuration file type icon Configuration file type

The esi file extension is related to the EtherCAT Configuration Tool and used to store slave information (some kind of configuration data).

EtherCAT is master - slave network developed by Beckoff.

Help how to open ESI files:

This file type is not meant to be opened directly, there is no software that could open and work with it directly, or there is no information available in public sources about opening this file type. This is usually the case of some internal data files, caches, temporary files etc.

How to convert file with extension ESI:

As far as we know, this .esi file type can't be converted to any other file format. This is usually the case of system, configuration, temporary, or data files containing data exclusive to only one software and used for its own purposes. Also some proprietary or closed file formats cannot be converted to more common file types in order to protect the intellectual property of the developer, which is for example the case of some DRM-protected multimedia files.
