Issue Details

I get Error -1073807331 when using a VISA property in LabVIEW.



Error -1073807331 occurred at Property Node

Possible reason(s):

VISA:  (Hex 0xBFFF001D) The specified attribute is not defined or supported by the referenced resource.


There's two main reasons of why a VISA property will throw this error:


A) The Property is not supported by the serial bus being used.


Example A.1: The Is Port Connected VISA property is only supported with serial drivers developed by NI, and documented to support this feature with the corresponding NI hardware. Please see the documentation for your driver version and Serial device to verify if this feature is supported. Built-in serial ports or serial ports made by other hardware manufacturers will not work with the Is Port Connected property. Additionally, this property is not supported by RS-485 hardware.


Example A.2: The 1394 Dest Upper VISA property will just work with FireWire serial bus, which will cause error -1073807331 when used with other bus (USB, GPIB, RS-232, etc.).


B) The Property can't be modified at that point in the program.


Example B.1: I am trying to communicate with my HP 34401A Multimeter using my serial port. When I try to run the Initialize VI, I get Error -1073807331 occurred at Property Node (arg 9) in HP34401A This error is related to changing the Line DTR or Line CTS states of the serial port. We cannot modify the state of a line used for flow control while the hardware is in use.

Arguments 8 and 9 of the property node in the Set Serial Settings portion of the block diagram set the DTR and CTS states. With the flow control set to DTR/DSR in argument 3 of that Property Node, argument 9 throws the error. If the flow control was set to RTS/CTS, then argument 8 (dealing with the Line CTS setting) would be the one causing this same error.

To solve this, download the latest version of the HP34401A driver from the Instrument Driver Network.
