Read temperature of PXI-4461 card using .NET

[shuli]

Is it possible to read the current temperature of the PXI-4461 using .NET calls similar to the way Measurement & Automation Explorer does on the Calibration tab?

Hi Shuli,

Yes, you should be able to do that, that functionality is part of the DAQmx driver. A quick search of the .net help for “temperature” brings up the Device.Temperature Property. Take a look at the Device Class members list, this shows a lot of methods and property available on the Device class. Second from the bottom is Temperature. Hope this helps!

Matt,

Thanks for pointing me in the right direction. My initial quick search was only finding Task commands.

I couldn't figure out how to initialize Device until I fortunately found the solution in the help documentation. "You cannot instantiate the Device class directly. Instead, use the LoadDevice method to obtain an instance of the Device class."

Hi Tapiam,

What Matt suggested was you try something like this:

DaqSystem.Local.LoadDevice("Dev1").Temperature; Dev1 should be the name of whatever device you're using as specified in MAX or as appears in DaqSystem.Local.Device. 

Hope this helps!

Hi Sean

Thank you for the information, it works properly, but just a little problem, when I try to run the app in the PXI. show this error: Could not load file or assembly  'NarionalInstrumen.common'  Ver:8.7.35.131.     I was checking in my PC, where I did the app and did not find the this version.  Do you know something about, how to fix it or where can find this version to install in my PXI?

Thank you in advance for your help

Hi Tapiam,

Is that the full context of the error? I found a similar issue in another discussion forum (linked here) where two or more versions of an assembly are being called. If you could, go through the KB linked there and post any further questions on that thread. Thanks!

Thanks a lot Sean F, we find how to fix it. just  update the Ver in the PXI.
