The FPGA Desktop Execution Node can return the following error codes. Refer to the KnowledgeBase for more information about correcting errors in LabVIEW.

Code Description
−61449 The FPGA VI has finished executing. The Desktop Execution Node attempted to update the simulation, but the FPGA VI has already finished executing. Ensure that Desktop Execution Node updates only occur while the FPGA VI is running. Additionally, if you want to simulate your code continuously, you must place your LabVIEW FPGA code inside a While Loop.
−61448 The simulation is not running. The FPGA simulation is not running. This can occur when the Desktop Execution Node tries to write to or read from a resource after the FPGA VI finishes executing. Verify that the FPGA VI is still running when the Desktop Execution Node attempts to interact with it.
−61447 LabVIEW cannot locate the VI. The Desktop Execution Node is configured to execute a VI that LabVIEW cannot locate. You must reconfigure the Desktop Execution Node to point to a valid VI.
−61446 The execution mode is invalid for the Desktop Execution Node. The selected target is set to execute in an execution mode that does not support the Desktop Execution Node. Change the execution mode to Simulation (Simulated I/O) to use the Desktop Execution Node.
−61444 The Desktop Execution Node is misconfigured. The Desktop Execution Node is set to write to or read from a control, indicator, or I/O resource that either does not exist or has changed data types. Reconfigure the Desktop Execution Node and run the simulation again.
−61443 The simulation has exceeded the maximum simulated time. The simulation has exceeded the maximum simulated time of 9223372036854775807 ps. LabVIEW will now abort the simulation.
−61442 The FPGA Desktop Execution Node cannot run the configured VI. The FPGA Desktop Execution Node cannot run the configured VI because it or another VI is already running under the selected FPGA target. Stop all executing VIs under the FPGA target to run the FPGA Desktop Execution Node.
−61441 Another FPGA VI for this target is already executing on the development computer. Stop the other VI before running this VI.
