LabVIEW creates an application instance for each target in a LabVIEW project. When you open a VI from the Project Explorer window, the VI opens in the application instance for the target. LabVIEW also creates a main application instance, which contains open VIs that are not part of a project and VIs that you did not open from a project. You can select the application instance for a VI by using the application instance shortcut menu.

Complete the following steps to select an application instance for a VI.

1. Navigate to the bottom left corner of the front panel window or block diagram. The application instance selection shortcut menu displays the current application instance of the VI.
2. Right-click the shortcut menu and select the instance in which to run the VI. The VI now runs in the selected application instance.

Note  Selecting a new application instance reopens the VI in the selected application instance. The VI also remains open in the original application instance.
