can the NLS xml be extracted in excel and automaticall filled and reuploaded in NLS ASpect. Will 800xA support it
I believe translations are made in .DLL files.
Login to ABB Library and download this old user's guide 3BSE025113R201. The tool mentioned in section 5 exists on the PPA\bin folder (afwnls something) and can be used to extract DLLs.
There exist tools (e.g. Visual Studio) that can edit these strings inside the DLLs.
Dissect an existing official translation package, e.g. Swedish and observe how installation injects a new folder PPA\SVE where .DLL files with translated texts are put.
With an SDK support contract you can file a support case and ask for help.
