Hi, Tamas!
You can translate the "default texts":(the string library 1 can't be translated but all others can be.
So the solution:
1; in your ladder place a "Set.Str.lib" (found in strings- set strings library), select library 2. (triggered by SB2, to run it at power up).
2;translate the texts in library2 (if you already have strings in library 1 you can export them and import as library 2). If you need spezial hungarian characters like "éá.." you can also modify the font type to a font where the spec .sharacters are enabled.
3; the alarm HMI screens will be in your language.
