editing device PDO assignment using the API

[Sgilk]

I am not seeing a method of editing device PDO assignment using the API client libraries. Am I correct that this is not supported?

Also, will this type of configuration always require the ctrlX I/O application, or might it be possible to accomplish this via REST API calls to EtherCAT Master app?

Moved to own topic from here.

As the configuration of the IOs is done via a XML file and this one is generated by the ctrlX IO Engineering you will have to use this tool or generate the file on your own and put in the corresponding folder (ActiveConfiguration/comm.ethercat.master/config/<name of your masterinstance>/ethercat.XML) on the ctrlX CORE e.g. via WebDAV.

I will check PDO edit functionality via REST API with our R&D.

I successfully modified the ethercat.xml file using a WebDav client written in C#. This will work for now, but it would be nice if this file could be modified via REST API as well.
