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

Code Description
−61506 The FPGA VI configured for running in simulation mode contains controls or indicators with duplicate names. The Read/Write function cannot read from or write to controls or indicators with duplicate names. Rename the controls or indicators.
−61460 Control and indicator names with newline characters are only supported when the VI execution mode is set to Simulation (Simulated I/O) and the FPGA VI reference is configured for Dynamic mode.
−61251 The bitfile is incompatible with the configuration of the FPGA interface reference wire.
−61221 Close and reset is not supported when the FPGA target execution mode is configured to Third-Party Simulation.
−61219 The number of elements requested must be less than or equal to the number of unacquired elements left in the host memory DMA FIFO. There are currently fewer unacquired elements left in the FIFO than are being requested. Use the Delete Data Value Reference function to release some acquired elements before acquiring more elements.
−61218 FIFO.Configure is not supported when configured with greater than 65536 elements and when the FPGA target execution mode is configured to Third-Party Simulation.
−61217 A session cannot be closed or reset and a bitfile cannot be downloaded while DMA FIFO region references are outstanding for the specified session. Use a Delete Data Value Reference function to delete any regions acquired from Acquire Read Region or Acquire Write Region before taking any of these actions.
−61216 A gated clock has violated the handshaking protocol. If you are using external gated clocks, ensure that they follow the required clock gating protocol. If you are generating your clocks internally, please contact National Instruments Technical Support.
−61215 Bitfiles that allow removal of implicit enable signals in single-cycle Timed Loops can run only once. Download the bitfile again before re-running the VI.
−61214 For bitfiles that allow removal of implicit enable signals in single-cycle Timed Loops, LabVIEW FPGA does not support this method prior to running the bitfile.
−61213 LabVIEW FPGA does not support Close and Reset if Last Reference for bitfiles that allow removal of implicit enable signals in single-cycle Timed Loops. Instead, right-click the Close FPGA VI Reference function and select Close.
−61212 LabVIEW FPGA does not support the Abort method for bitfiles that allow removal of implicit enable signals in single-cycle Timed Loops.
−61211 LabVIEW FPGA does not support the Reset method for bitfiles that allow removal of implicit enable signals in single-cycle Timed Loops.
−61210 There was an error initializing the LabVIEW FPGA Simulation.
−61209 This function is not supported when the FPGA target execution mode is configured to Execute VI on Third-Party Simulator.
−61208 This function is supported only when the FPGA VI reference is configured for Dynamic mode and the FPGA target execution mode is configured to Execute VI on Third-Party Simulator.
−61206 The configured item does not exist.
−61205 An item of the selected name is present but is a different data type than that configured in the Open FPGA VI Reference.
−61204 The operation could not be performed because the FPGA is busy operating in Simulation mode. Stop all activities on the FPGA before requesting this operation.
−61203 The operation could not be performed because the FPGA is busy operating in Interactive mode. Stop all activities on the FPGA before requesting this operation.
−61202 LabVIEW could not perform the operation because an FPGA VI reference to another VI is currently open. You must close the currently open FPGA VI reference before attempting to perform this operation.
−61201 The chassis is in Scan Interface programming mode. In order to run FPGA VIs, you must go to the chassis properties page, select FPGA programming mode, and deploy the settings.
−61200 The operation could not be performed because the FPGA is busy operating in FPGA Interface C API mode. Stop all activities on the FPGA before requesting this operation.
−61183 The transfer function order exceeds the maximum order allowed.
−61182 The transfer function is improper. The order of the numerator must be less than or equal to the order of the denominator.
−61181 The notch width or Q factor must be greater than zero.
−61180 All frequencies, f, within the notch region must meet: 0<f< fs/2, where fs is the sample rate.
−61170 The real and imaginary input data arrays must be the same size.
−61169 The input parameter is not achievable on the FPGA at the given clock rate.
−61168 The channel index input is out of the range of the configured number of channels.
−61167 This function is not supported when the FPGA target is configured for Simulation.
−61165 You cannot execute this FPGA VI for Simulation because the FPGA VI is broken.
−61159 This function is not supported when the FPGA target is configured for Simulation with Real I/O.
−61141 The operation could not be performed because the FPGA is busy. Stop all activities on the FPGA before requesting this operation. If the target is in Scan Interface programming mode, put it in FPGA Interface programming mode. If RIO Device Setup or MAX is currently open for downloading a bitfile to flash memory on the device, wait until the download ends.
−61078 The requested memory could not be allocated.
−61077 Terminated DMA FIFO. The FPGA was reconfigured while the DMA FIFO was in use.
−61076 The DMA transfer did not complete within the timeout period.
−61075 The DMA transfer was aborted and did not complete.
−61074 The timeout parameter must be -1, 0, or a positive integer.
−61073 The number of elements to read or write must be less than or equal to the depth of the host memory DMA FIFO.
−61072 The requested FIFO depth is invalid. It is either 0 or an amount not supported by the hardware.
−61071 The selected DMA FIFO was not found in the bitfile or FPGA design or is out of sync with the bitfile.
−61059 The selected control was not found or is out of sync.
−61021 FPGA Interface is out of date with the FPGA VI. Right-click and select Refresh.
−61017 You must recompile the VI for the selected target.
−61016 You must compile the VI for this target.
−61015 No bitfile was found for download. You must compile the VI for this target.
61003 The FPGA VI specified by the Invoke Method function with the Run method is already running. The interaction of the FPGA VI and the host VI might produce unexpected results. For example, executing this host VI may modify front panel values on the running FPGA VI. User interaction with the front panel of the FPGA VI may affect the execution of the host VI. Terminating either the FPGA VI or the host VI may terminate the other.
61060 The Wait on IRQ method timed out before the specified interrupt was received.
61211 Multiple resources with the same name are present in this VI. The Dynamic Mode of the FPGA Interface can only access a single resource of a given name.
