Instrument descriptor not recognised

[Bazza]

I have a PXI-4060 DMM in a PXI chassis connected to a desktop PC via MXI-3, running LabVIEW 7.0. My intention is to use the NI-DMM IVI driver to read from the 4060. I have used MAX to setup the Logical Name and Driver Session. To do this I followed some instructions I found on this site with regard to setting up and using MAX to configure IVI instruments (although the instructions were for MAX 2 and I am using MAX 3, so there were/are some confusions). The soft front panel for NI-DMM succesfully reads the resistance from the 4060, but when trying to use the iviDMM Initialize.vi I get error "Error -1074118655 occurred at IviDmm Initialize With Options.vi"?! Anyone got any ideas? Even the example VI supplied with the LabVIEW inst
allation gives this error so im sure that its a MAX configuration thing. My setup is: simulation = unchecked, Hardware Asset = PXI-4060, Resource Descriptor = PXI6::13::INSTR, Software Module = NIDMM. Virtual Name/Physical Name are elft empty as I couldnt really find any info as to what exactly they are - maybe this is the problem? Initial settings isn also empty.

I hope someone can shed some light on this problem.
Thankyou, Barry.

The Resource Descriptor in the set up is not valid. More specifically, the valid syntax for NI-DMM instruments is:

DAQ::n[::INSTR]

where 'n' is the NI-DAQ device number of the NI-DMM device (in this case the PXI-4060) in MAX.

If you change the Resource Descriptor to:

DAQ::1::INSTR

you should not see the error, assuming that the PXI-4060 is device 1 in MAX.

I am also having the same problem.

I have tried changing the Resource Descriptor to the suggestion, now I get, "Error - 1074118656. Device was not recognized. The device is not supported with this driver or version"


I have installed the latest NI-DMM driver (2.2) but still no answer."

Anybody have any insight or answers to this question

Anybody has the solution?

Hi,

Have you tried this KnowledgeBase article? It lists different resource desriptor names you can use.

Hope this helps!

We are having the same problem.

Even the example vi from NI does the same thing.

We tried installing many versions of NI DMM too.

The driver initializes once and makes a reading then every subsequent run of the VI produces this error.  Re-booting the PC makes it work one more time.

Hi TAS1,

Are you closing the reference to your DMM at the end of your program?  If the reference is still open then you cannot open another reference to it.  This could be a reason why you can run it once and not subsequent times.

[TAS1]

Yes, reference was supposedly closed by the demo VI I was trying.  The problem ended up being somewhere in the drivers that come with LabView 7.1.  Even after uninstalling everything and re-installing, I still had the same problem.  I tried upgrading the driver to several newer versions but had to go all the way up to the latest drivers to get things working
