• Interval: Global update rate [ms] for refreshing the HMI server symbols.
• Subscription Mode: Update mode between server and client.
• Change: The client is only informed of changes to the symbol values.
• Poll: The client receives the symbol value cyclically, even if no change has taken place.

• Project File: The name of the project file.
• Project Folder: Absolute storage location of the project.
• Default Language: Default language that is loaded for the HMI project. This setting can be overwritten by the settings per user or switched in the client.
• Time Format Locale: Time format of the currently set time zone that is loaded for the HMI project. This setting can be overwritten by the setting per user.
