Issue Details

After replacing PXI chassis or modules, running the existing application in LabVIEW results in getting the following error:
Error -88705 occurred at DAQmx Reset Device.vi:4740001
Possible reason(s):
The specified device is not present or is not active in the system. The device may not be installed on this system, may have been unplugged, or may not be installed correctly.
This error is shown in the following dialog box.
The code previously worked correctly before the hardware change, how can I resolve it?

Solution

NI MAX automatically assigns a device name when hardware is connected to the system.

When a PXI chassis or module is disconnected and reconnected:

  • The previously connected device remains in NI MAX with a “Not Present” status
  • The newly connected hardware is assigned a new device name (e.g., PXI1Slot1_2)

If the LabVIEW application code references a fixed device name, it may still attempt to access the old device that is no longer present. This mismatch causes Error -88705.

To resolve this issue:

  • Open NI MAX (Measurement & Automation Explorer)
  • Identify the device name used in your application code
  • Rename the newly detected device to match the device name expected by the code (Alternatively, update the code to use the new device name)

Ensure that the device name in NI MAX and the one referenced in your application are consistent.
