VI stops saving data to file

[CoastalMaineBird]

The total amount of files per day is about 15,000.

OK, I would suspect that.  What OS are you on?

Any OS will have a certain amount of trouble with that many files in one folder.

Consider implementing an hourly folder to reduce the number of files in one place.

I see no popup dialog in case of an error in either of your VIs.  I see where you do your error checking after the file write for your analog data, but the "error out" terminal in your file writing VI never exits the VI into your main program!  In fact, your main VI doesn't even contain an "error out" indicator.  Where, exactly, is the code containing your pop-up message?  The only error cluster in your main VI is connected to your queue functions.

So I still don't see how you know whether or not an error occurred.

Take the "error out" cluster of your file writing VI and wire that to the terminal of your upper "While" loop instead.  That way your loop will stop if an error occurs during your file write.

Or, as I suggested earlier, put a probe on the "error out" terminal of your file write VI and monitor that while your program is running.

We implemented this daily breakup about three weeks ago, before that we had many days worth of data in the same folder, about 100,000 files.

Again, we started noticing this about a week ago.

The OS is "Server 2003 ". I mentioned XP, but I made a mistake.

Why wouldn't the VI give an error?

[DianeS]

The VI will indeed give an error if one occurs.  The issue is that, in your main VI, you have no way of seeing it.

[CoastalMaineBird]

It's not really an error, but it could slow things down enough so that your logic stops working (I haven't looked into detail at your code).

Hi Diane,

I know there is no proper error handling for the analog file save, but for the digital, if you look into the "Write To Spreadsheet File" block diagram you will see that there is a "general error handler.vi" which will produce a popup message.

DianeS is right - your subVI goes through a lot of trouble to pass an error message out, but your main VI ignores it.

Perhaps you have an error and cannot see it. 

[DianeS]

Suppose the error is occurring in your analog write?

Hi Steve,

What do you mean with "your logic stops working"?

I noticed that the front panel continues to update with new data.

I had a feeling it had to do with the amount of files in the folder, but I could not find anything that states the limit of that number.

Diane,

Should'nt it generate the digital file anyway?
