search for FPGA boards ( VI_ATTR_MODEL_CODE )

[FritzFranz]

I used the "Visa Find Resource" and the VI_ATTR_MODEL_CODE to search for a specific board. VISA resource names are no longer supported to connect to a RIO device. Instead the RIO Resource should be used.

I have customers that have different types of boards (PCI-7831 and PCI-7833) simultaneously in the computer.  

1) How can I get the reference to the correct board or how can I check which cards are installed?

2) What is the VI_ATTR_MODEL_CODE of the PXI-7831R?

Hi Mr Rychen,

I don't really understand what you said when you say "VISA ressource name are no longer supprted..."

I run the attached VI and could see the ressource description of my RIO card on my computer.

Can you try this VI and check if it works on your computer.

Can you send me the lsit of the software that you have on your computer?

Have a great day.

Regards.

Thanks Matthieu for the reply

In LV8.5 NI says that the VISA reference to open a FPGA reference is no longer supported and the RIO reference should be used instead.

I still use the search VISA and then I convert it to a string and then I still can use the open FPGA reference.

I was just wondering what is the difference between the RIO reference and the VISA reference. And how I should do in the future.

Meanwhile I found the the attr_model_code of the PXI-7831R. It is in the resource.xml under

C:\Program Files\National Instruments\LabVIEW 8.2\Targets\NI\FPGA\RIO\R Series\78XXR\783XR\7831R\PXI-7831R\resource.xml
