How to rename the GSDML file?

The GSDML file can not be renamed. The file name of the GSDML file is also stored in the file itself. If you now rename the file, the original file name is retained in the file. Using this renamed GSDML file, the system reports that the inserted file can not be included because it does not correspond to the valid format.

Script with station name

Meaning, if the UNIGATE will be started in the config mode, the name will be taken from the file devname.txt. If a name is then set in the PROFINET Master it is effective from now on.
