Solution
You can control a VI or RT EXE running on an NI Linux Real-Time controller from several sources. For example, control can be established from a development PC running a VI interactively, through Remote Front Panels, via remote debugging tools, or directly from the controller's embedded UI.
However, control is exclusive and can only be held by one source at a time. When the Remotely Controlled message appears on the embedded UI, it indicates that another source has already obtained control of the VI or RT EXE. As a result, the embedded UI becomes read-only until control is released by the active client.
If you want to regain control from the embedded UI, stop or disconnect the active client that currently has control of the application. Once the client releases control, the embedded UI will be able to interact with the VI or RT EXE again.
For example, if you are deploying a VI to an RT target from a development PC, complete the following steps to transfer control of the front panel to the embedded UI:
- Run the VI from the host computer to display the front panel on the embedded UI.
- Disconnect from the target by right-clicking the RT target in the LabVIEW Project Explorer window and selecting Disconnect.
At this point, observe that the Remotely Controlled message previously on the Embedded UI panel is now gone.
