What you are looking for is a Real-Time Startup Application or Executable.
You can create a new startup executable build by going to the very bottom of the project tree under the GPIC RT controller, then right-click on Build Specifications and go to New>Real-Time Application. Then, on the Source Files tab select the top level RT VI that you want to run at bootup. Typically you can use the default values for the rest of the settings.
Next Build your startup executable. When it completes, right-click on the Build Specification and go to Deploy. After deployment, right-click again and set it to Run as startup. It will prompt you to reboot the control system.
Finally, launch NI MAX, go Remote Systems, find the controller and go to the Controller Settings tab. Make sure Disable RT Startup App is NOT checked. This setting over-rides your LabVIEW Project setting to Run at Startup, so it must be unchecked for the application executable to run at boot.
See the GPIC Reference Design project (unzip to short path) for some examples of RT startup executable build specifications.
There are also build specifications under My Computer in the reference design that show you how to make a Windows installer and Windows application for your host graphical user interface application. That way, operators can use your power converter user interface without having the LabVIEW development environment installed on their computers. By using unique identifiers, you can make it so that only the correct GUI application for a particular RT application is able to connect to it.
You can also right-click on your FPGA application and go to Download VI to Flash Memory. Also, you'll typically want to set the FPGA build specification to Run when loaded to FPGA. In this way, the FPGA application can start running before the RTOS is booted- very quickly after power up.
