how to use Write to LavView measurement file

[NI9233]

Hi,

      Can you tell me details about the Write to LabView Measurement file ? How to use it ? Can i make the direction for the file myself or auto directory? In which application can i use? and how to change the microsoft excel format to labview measurement(.lvm) ? Can i need to use something like array for using write to labview measurement file? Thanks a lot.

Best Regards,

Su

Hi,

you cannot connect an array directly to the Write to LabVIEW Measurement file.vi. If you try to connect it, LabVIEW will automatically use the Convert to Dynamic Data VI which is the datatype all the Express VI's use.

The dynamic data type will include the original array data plus timing information. If you want to ignore the timing information, double-click on the Write to LabVIEW Measurement file.vi and choose 'Empty Time Column'.

Then you can ignore this Empty Time Column whn you open the file in Excel. You don't need to worry about the microsoft exel format, you can open the file generated by LabVIEW straight into Excel.

Double click on the Write to LabVIEW Measurement file.vi and select the path where you want to save the file.

Hi,

perhaps the systems administrator has not given you the rights to save files on that directory. Try to choose a valid directory by double-clicking on the Express VI and selecting a valid directory.
