Im not expert for this but using chatGPT and google i found this:
This error indicates that the GSDML file (Generic Station Description Markup Language) being used is not compatible with the current version of your software or hardware configuration.
in version history of GSD package is mentioned that GSDML V2.25 is included.
Conclusion:
You have to contact official B&R support and request update
Hello, B&R does not offer a newer file with a newer GSDML version (as there is no benefit of this new version)
Therefor you have to get in contact with the software manufacturer and ask why they need a GSDML version above 2.25 and why they are not compatible with older versions
As I mentioned, I’m not an expert on this topic. Oliver is. So if there is no benefit from the newer version, then the import limit to certain version makes no sense. Usually, software manufacturers try to keep backward compatibility.
