Language switching

Language switching allows you to deploy an application in different languages. At design time, you can design an application with user-defined text strings in up to 40 languages. At runtime, you can switch between up to 20 application languages dynamically using a language switch button for each language.
The user-defined text strings that support language switching are those that an operator sees in an application at runtime, including:
  • Text objects created in graphic displays and global object displays
  • Graphic and global object display titles specified in the
    Display Settings
     dialog box
  • Labels and captions on graphic displays, including alarm trigger labels
  • Embedded time and date and numeric variables
  • Alarm, local, and information messages
  • Captions and shorter messages in the dialog boxes of
    User Management
     buttons and the
    Electronic Signature
    dialog box
  • Text strings defined in the extended properties of controller tags
    TIP:
    Make sure that you define the controller default language when multi-language is enabled.
    • If the requested language is not available in the controller, the application shows the default language defined and enabled in the HMI.
    • If the HMI default language is not defined in the controller, the application uses the controller default language or the single language that does not have an ID.
