How can I import a voltage profile from labview to multisim

[goodtimesblues]

Hi there,

    I am using Labview and Multisis student edition, and I am trying to use the voltage I record from my DAQ unit as a source voltage in my Multisis circuit.  I just can't figure out how to do it.  I hope the student editions can do it!  Any help would be great.

Thanks,

David

Hello,

You can save the acquired data in LabVIEW using the LVM (LabVIEW Measurement file) format. Look for this Express VI in the File I/O palette: 'Write to Measurement File'. Then in Multisim use the LVM source in order to import the data. Take a look of the following tutorial:

Importing Data from LabVIEW Measurement (.LVM) Files into Multisim

I hope this helps.

That is very handy to do! Can you take your finished Multisim circuit and put it into LabVIEW as a VI?

Hi Ryan,

Moreless.... you can use the Automation API (ActiveX) of Multisim to control Multisim from within LV, so you can send data to your circuit for simulation, then get the output data back. All from within LV and without opening Multisim.

So, you can bundle all this inside a subVI and call it from LV...

In Multisim 10.1 check the Help file you will see a section for the automation API...

BTW... I'm currently working on building a complete LV library as a wrapper for the automation API so you will already have all the functions ready in LV... we will be posting it in about two months maybe once they are tested, added express VIs, documentation and examples...
