Writing data to file in a timed loop

[bbentelin]

I am editing a previously made block diagram, and I'm having trouble writing my data to a file.

I want to have the mean histogram value recorded every 5 minutes into a data file

Do I need to worry about error? 

Here is the vi attached as well.

Thanks

Not much info to go on here.

What error are you getting?

[bbentelin]

Indeed that was vague.  I'm completely new at labview, do I need to route error wires through my file saving operations?  If I set it up for a save file prompt, will the time loop save to that same file on each of its iterations?

[RavensFan]

It is always a good idea to wire up the error wires.

For a file save, it all depends on how you program it.  If you have a prompt that you ask for a filename before starting your loop, it will always write to the same file.  If you put the prompt inside the loop, it is going to ask you for a filename each and every time which will be a pain to the user.  If you wire it up as a file path control inside the loop, it will give the user the option to change the file path during execution.

If you want to have the ability to prompt for a new filename anytime during execution, but perhaps only when the user hits a button on the front panel such as New File?, you can put the dialog prompt function inside a case structure.  Then by putting the filepath wire into a shift register, that file path will be available for later iterations.

Since you are completely new to LabVIEW, you may not have seen these.  I would recommend looking at the online LabVIEW tutorials
