Receiving Error -1074118656 when Running NI-DMM VIs

  • NI-DMM

Issue Details

When I run an NI-DMM example VI in LabVIEW, I receive the following error:

Error -1074118656 occurred at niDMM

Possible reason(s):
Error: (Hex 0xBFFA4000) ERROR: Device was not recognized. The device is not supported with this driver or version.

How can I resolve this error?


The most common cause of this error is having an incorrect Instrument Descriptor entered on the front panel of the VI. A valid instrument descriptor for a National Instruments DMM should have one of the following formats:
  • NI-DAQmx name 
  • DAQ::NI-DAQmx name[::INSTR] 
  • DAQ::Traditional NI-DAQ device number[::INSTR] 
  • IVI logical name

This error also happens if you try to call the Initialize with Options VI in driver simulation mode, without first setting Simulate = 1 in the Option String control.

The NI-DAQmx name or Traditional NI-DAQ device number for your DMM is listed in Measurement & Automation Explorer (MAX) under the Devices and Interfaces listing. For more information, refer to the niDMM Initialize or niDMM_Init topics of the NI Digital Multimeters Help at or at Start»Programs»National Instruments»NI-DMM»Documentation»NI Digital Multimeters Help.

Refer to the National Instruments IVI™ Driver Help to create IVI logical names for your DMM. In this help file, refer to the IVI Driver Help Introduction»Configuring Your System Using MAX»Measurement & Automation Explorer Help for IVI section.

Additional Information

If NI TestStand, LabVIEW or CVI is being used with an IVI-DMM driver session, use the DAQmx names for the Resource Descriptor under the hardware tab in MAX if the device is National Instruments hardware. (e.g.,  PXI1Slot6).

A less common cause of this error could be caused by the NI-DMM 3.0.6 version of the driver when using a NI 4050 or NI 4060 DMM device. With the release of this driver, the support for these devices was broken on Windows XP machines. However with the release of NI-DMM 3.0.6 f1, this issue has been fixed and normal operation of the NI 4050 and NI 4060 devices is restored.

You can download the patch from the following link: NI-DMM 3.0.6 f1.
