回复： Write a TDMS file with a web application

[Skeggy88]

Hi,

I built a web application that read data from a DAQ and visualize it in a waveform. Also turn on and off a light clicking a button.

Can I save acquired data in a file?
Thank you,
Veronica

Hi, do you use labview or other NI software to build your application? 

[Skeggy88]

Hi,

I use Labview and web ui builder.

I don't know if I can save data acquired by DAQ assistant.

According to corresponding experts, Web UI builder is a sandbox and can't access files in local file system. The only way to do IO is through other web services. Look's like there's no current TDMS function to do that.

So is impossible to save data in some way??? Also a txt file, I don't know!

Or do you know a tutorial in which I can see how to interface the web ui builder application with another application that allow me to save files?
I don't know what to look for.

If you use LabVIEW AND the WebUI Builder it should be possible to implement the logging in LabVIEW and the control and visualization with the WEB UI Builder.

Can you link me a tutorial?
When I run the application and the DAQ starts, the program doesn't create the file like usually does.
I think I have to give a command to start the creation of the file
