save to series of files resets to single file

I'm attempting to save six channels of dynamic data using the Write To Measurement File Express VI, and wanting to separate large amounts of data into multiple files. When I modify the module properties, click on the 'save to series of files' option and click ok, the module closes but resets to 'save to one file'  -  ie, it only saves to one file, and if I reopen the properties menu the 'save to one file' option is selected.

How can I get it to save to multiple files?

Hi Starstrike,

 

I am assuming that you are using LabVIEW 2009. Unfortunately there is a bug in LV 2009 that does not allow you Save to a Series of files. This bug was not present in previous versions of LV and has been addressed in LV 2010.

 

The official workaround for this is to convert the Express VI to a standard subVI by selecting 'Open Front Panel' using the short cut menu (right click) for the Write to Measurement File Express VI.

In the generated SubVI, go to the block diagram and change the constant "multi_file" to True.

 

I hope this helps you out.

 

Best Regards,
