Configure session and fallback locales

Set the session locale to determine the language for text, format or data, and measurement system for values. The session locale at runtime is based on the user locale or the Session UI object.

If there is no locale for the user or Session UI object, the project uses the first locale in the Locales property. Configure fallback locales in case the user-defined session locale is not configured at runtime, or translation is not available for a session locale.

  1. In Project view, select the project node.
  2. In Properties, expand Localization, and then in Locales, type one or more locales separated by commas. For example, it-IT, Fr-FR, en-US.
    Tip: FactoryTalk Optix Studio adds a column in the Translation Editor table of the LocalizationDictionary object for each new locale.
  3. In Translation fallback locales, enter additional locales, separated by commas, such as it-IT, Fr-FR, and en-US.
Tip: At runtime, FactoryTalk Optix uses the first locale in Locales property that is set for the project or the locale that is set for the current user. If the list of locales contains an unsupported locale or a translation is missing the LocalizationDictionary, the project uses the first fallback locale.
