Write to new TDMS file each time program runs
Hi Superjurg…,
create a filename on your own each time your program starts, maybe using FormatDateTimeString and BuildPath!
Wire this filepath to your TDMS save function.
That's pretty simple. When you're new to LabVIEW I recommend to take all those FREE online courses offered by NI on their website…
Hi Super,
right now you create a new filename each second…
- You should create file name before the loop starts. That way you only deal with the same filename as long as your loop runs.
- I would advise to use a more suitable format for your date/time string. Something like "%y%m%d-%H%M%S.tdms"…
- You should open the TDMS file before the loop starts and close it after the loop has finished. No need to open and close it in each iteration…
- What kind of filepath is generated and wired to TDMSOpen? Did you try to debug that?
Adding to Gerds comment, if you look at the output of the Get Date/Timestring-function, it'll result in 16:32, causing an invalid filename as you cant have colons in the name. You probably also want the seconds active, and you dont need the Get current time, as it's the default for the get date/time string.
Format into string is the solution. 🙂
