write file measurement

[hanumeshbujji]

Hello every one...iam facing a proble..i.e iam saving data using write to file measurement.in this iam connecting signal data and some caluculated data but it saving only time remaining things only saving in first row ofter rows nothing saving...so my need is to save all the reading continously until end of running aplication...

 Thankl you

Hi hanumesh,

the VI is working as "intended" aka "as you programmed it"!

You generate a sine wave signal with 100 samples per iteration. Then you join 3 scalar values as additional signals. Exactly this is written to your measurement file as can be seen in this snippet:

X_Value	Sinus	Untitled	Untitled 1	Untitled 2	Comment
0.000000	0.000000	1.000000	2.000000	3.000000
0.001000	0.634176			
0.002000	1.265799			
0.003000	1.892325			
0.004000	2.511234			
0.005000	3.120033
…

First column is time, 2nd is your sine, 3rd-5th contain the additional scalar values…

When you want to have "filled" columns you need to supply waveforms (of 100 samples) for your additional values too…

so for this any substitue method available..plese share

the above vi just a model of original design...iam givind daq data and calculatiob data to the measurement file...thank you

Hi hanumesh,

your "additional data" should have the same amount of samples as your DAQ data - simple as it is…

thank you sir...
