Did you try to check the inputs for ScanFromString using probes?

This way you can easily find the reason for that error…

Hi Gerdw,
Yes I tried the probe, I saw that it only takes commas as input and yet I have the values in the table that I use as input, but I still can't figure out why, I've tried many things but I'm still stuck on it.

I really don't know what you are talking about…

 

In your VI you initialize the shift register with an array of 10 empty strings.

In the timeout you try to parse that array, but ScanFromString fails because it cannot find the expected data in your array of empty strings!

 

Did you really use probes (and highlight execution) to find the problem?

Best regards,
GerdW

Hi GrdW,


Yes ScanFromString failed because the array is not filled it is empty.

Yes I did the probe.
Now how to make ScanFromString act only when the array is filled please?

IF array element is filled
THEN ScanFromString

 

Or implement some error handling to act appropriately upon that error…
