User locale configuration
    The user locale is personal data that specifies the session locale at runtime. Set the user locale in the 
Locale
 property of the User
 object. If the 
FactoryTalk Optix Studio
 does not support the main locale, use C# to have APIs return nodes and set multiple locales for the same user. The order of user locales determines the priority for the session locale.When the session locale is set automatically at runtime based on the user locale and no user locales are configured, the session uses a fallback locale. 
     TIP: 
    Use the 
Session UI
 object to manage the session locale for a multilingual project that does not have user locale information. The user must then select the locale at runtime. Provide Feedback
