save data in tdms

Hello EveryOne,

I used RT FIFO functions to acquired data from My Controller and read it, so far everyThing goes very Well. But when I tried to save data in TDMS'file, my data is saved in one column as  shown in picture "File2"

I attempted To read data without using RT FIFO process, and it works

I think I made a Mistake in RT FIFO Process. Did-I?

Thank you in advance
