The Simulink® Real-Time™ Explorer environment consists of the property settings you define for the Targets pane. You can save your settings for the next session.
Set properties in the Targets pane.
After you change one or more properties and press Enter, the Save button and menu item are available.
To save your environment properties, click the Save button in the toolbar.
If you do not explicitly save the environment settings, Simulink Real-Time Explorer asks on exit if you want to save them.
When starting, Simulink Real-Time Explorer loads the last-saved set of environment properties.
