I have a Reset RT App variable showing under the Chassis I/O in my FPGA target in my LabVIEW project. What is this variable for?

The Reset RT App is an I/O node that will allow you to reset the RT program from your FPGA. Writing TRUE to this I/O node restarts the LabVIEW RT runtime engine while allowing the FPGA program to continue to run.

To use it, simply drag and drop this variable onto your block diagram in your FPGA code.
