Dear valentin.
There is a library available in the Eaton downloadcenter with functions for connecting/disconnecting,
read/write, etc.
The site is "downloadcenter.moeller.net" and you have to look for EASY_COM library.
Maybe this link is working
downloadcenter.moeller.net/en/software.203a88e9-36ea-425c-956f-71b528162ec3
