Save data in Real-Time when the CPU stops to work in the right way

[pasticciona]

Good morning!

I'm working in LabVIEW Real-Time on PXI Controller 8186 and I would like to know if it's possible to save continuosly data in a way that allows me to find data (and...than open them) on the hard disk even when the CPU stops to work when for example the file has not been closed or during writing operations. The OS Windows with file system NTFS should work (I suppose but I'm not sure) in a way that allows the creation of recovered files but LabVIEW RT need file system FAT32; the host doesn't see the second partition with NTFS that I have on my controller so I can't write data on it, for example. My problem is also that the writing operations have to be fast.

I know that this problem could be without solution however if someone has some suggestions..... I thank him in advance!

ciao ciao

Hi Simona,

sorry for the late reply. I don't understand vary well some parts of your post; for example:

• How fast do you have to write data? Do you need just a simple text file or it is necessary to adopt binary files? Refer to the following example: Logging Data with a FieldPoint FP-20xx to a Spreadsheet File;
• What do you mean by "..save continuosly data in a way that allows me to find data (and...than open them) on the hard disk even when the CPU stops to work when for example the file has not been closed or during writing operations." ? I need to verify that if the system hangs while writing into a text file then you will loose the written data;

I'll reply as soon as possible,

Best regards,

Fabio
