IVI for NI USB-6501

[MemoFonseca]

Hello:

I am trying to create an IVI driver for the NI USB-6501, at the time I am creating the "instrument diver software module", I do not know which .dll I have to reference to specify the "Module Path (32 & 64 bit)". (See attached for more info).

Thanks in advance,

Memo

A 6501 is programmed with DAQmx and not IVI. Why are you trying this?

I want to create an IVI so I can use it with TestStand.

That does not make any sense. There is no IVI class for digital I/O. You can use a call module, the daq assistant, or a DAQmx step.

Hello Dennis, thaks for your attention.

When you say to "call a module" you mean to use the "call executable" step in testand? Because I do not want to use the device "test pannel" I would like to call the various fuctions thru testand. About the DAQmx stem you mention, can you give me more info about it?

You must be extremely new to TestStand if you don't know what a code module is. I would suggest reading the tutorial that comes with TestStand. A code module is a step that you write with LabVIEW, c, etc.

Sorry I might misunderstood about what you try to mean by calling the module. But that is the part I want to skip, I have used IVI's for DMM's and Switches thru testand, without the necessity of CVI or LabView. The specs of the NI-6501 specifies the use of IVI's so that is why I am looking forward for this solution, I will keep digging into it.

Thanks for your help Dennis!

Where do you see IVI mentioned in the specs? Please provide a link and the page number.

A custom step is an advanced technique. I created dozens and did not use code modules. I had a basic one for some DAQmx functions but no longer have the code, sorry. Search the forum as this has been asked before.
