Explanation:
As regards languages, we have to distinguish between the UI languages (the language in which menus and commands are shown), the languages in which system error messages are displayed and the configuration languages (in which buttons and graphics are labeled).

• The ProTool interface (configuration interface) can be set to any of 9 languages.
  The choice covers German, English, Spanish, Italian, French, Chinese (traditional), Chinese (simplified), Japanese and Korean..
  You can change them - if they are installed - in ProTool Setup ("Start > SIMATIC >  ProTool Pro CS V6.0 > ProTool Setup > Change ProTool Language")
• There are 21 permanently installed languages available as standard for system messages on CE panels (e.g. TP/OP170,...) or Runtime (ProTool/Pro) for PC systems:
  German, English, Spanish, Italian, French, Chinese (traditional), Chinese (simplified), Japanese and Korean, Czech, Danish, Greek, Finnish, Hungarian, Dutch, Norwegian, Polish, Portuguese (Brazilian), Russian, Swedish and Turkish.
• An offline project can be created offline in up to 32 different standard Windows languages, provided the required language was loaded in the Windows country setting.
  ("Start > Settings > Control Panel > Regional Settings > Regional Settings Properties")
• There is a panel on which you can load up to five languages from the offline configuration. But it depends on the panel used (e.g. TP170A max. one online language)
• Online keyboards or virtual alphanumeric keypads always have the English font with CE panels. Other languages are not available at the moment.

Note:
If you load a language onto a panel that is not a standard language, the system error messages for this language are given in English.
Languages that write from right to left cannot be used with Windows-based devices. (e.g. Arabic, Hebrew etc..)
