I am not sure I (and probably others too) understood your problem properly.
1) Do you have a difficulty capturing data ?
2) Do you have a difficulty saving the data ?
3) Do you have a difficulty converting string data to integer data ?
Can you give a sample string of the data coming from the machine.

I capturing data properly as format string (the data is wieght from balance), In my VI I have too acquisition for thermocouple and sensor and I save the all of them in "Write on file of mesurment", my problem is: "Write on file of mesurment" support juste the Integer format, then I must convert the signal string to Integer (is my solution) maybe you have other solution
best regards

Hello hmed.
I dont really work with the labview file format for my data storage, hence I wouldn't be able to answer you on that.
But I build softwares for my machines (Tensile Testers) which have load vs deflection data coming from the machine.
I split the string and separate the load and deflection values.
I then plot a graph and put this all on a PDF report.
In some variants, I have to save the data or user inputs for which I use a simple Text file which allows me to save data in Alphanumeric format. So your string could directly go into the TEXT File.
I am almost certain that the LVM (Text) format should allow usage of alphanumeric strings and not restrict it to numbers / integers only.
I think we used the LVM in the past to store the same data that we now store in a TXT.
For all purposes, I feel that the write to text file option is more convenient. Its so much easier to read and write to a TXT file or a Spreadsheet XLS,
Ofcourse if the application is simple (like mine).
For a lot of data and database type application, I guess TDMS / LVM file may offer better control.
