Calling NIST from Labview

[Kim_Shrewsbury]

Does anyone have any experience using NIST software with Labview.  I am wanting to call NIST to get properties of two different gases, and not exactly sure how to accomplish this.

Can anyone point me in the right direction?

I use a TCP connection to get NIST time.  Not sure if something like this is available for what you are looking for.  Hope it helps.

NISTime-32.exe is shareware and available here

Their is a command line hook so you can just call it with the system exe from LabVIEW

I guess that you want to use the NIST refprop library.
The NIST software comes with a DLL.
You can call the functions in the DLL by using the "Call Function Library Function Node".
In LabVIEW 2010 it is located in the functions palette under "Connectivity".
