Simulation drivers

[Shivapriya]

Hi All,

       Actually i have installed the NI DAQ so i happened to get a "sim" folder in C:\Program Files\National Instruments\IVI\sim location. I didn't understand what are the drivers present in this folder are for?? and how they exactly differ from the IVI drivers which can be run in simulation mode (by setting a parameter in initialize method)...I want the difference between the "simulation drivers" and normal IVI drivers which can be run in simulation mode...

Thanks in advance.

Regards,

Priya.

Priya,

You didn't mention whether you're using LabVIEW or LabWindows/CVI, but it looks like those drivers are the instrument simulation drivers for use with LabWindows/CVI.  Are you using simulated IVI instruments in LabVIEW?

Hi Chad,

Thanks for ur reply...Actually i am using LabWindows/CVI. I want to know how to run those simulation drivers. There are 5 simulation drivers provided by NI. So please explain me the step by step process (using anyone of them) how to run them??

Also, i want to know if the data for simulation can come from some input stream - ASCII text files,database or DataSocket. For example, instead of generating the simulated output (in measurement instruments) as a random number, can we get the input from some input stream source and playback the response that was previously recorded?? This would be helpful when one has already run a particular test on a instrument and recorded the output data...and during simulation we just playback the data which was already recorded...

Can u tell me more about this record/playback concept when data is stored in some stream...I am actually a fresher in this field, so i have a vague idea..kindly help me out...

Thanks in advance!!!

Priya.

Here is the document that explains what simulation drivers are and how to modify them:

Note: The IVI Driver Toolset has been discontinued and therefore these simulation drivers are now distributed with the IVI Compliance Package.
