Data storage, add name to single value of a channel

[FM82]

Good day to all.

In my application i use data storage VI's to enable data collecting abilities. I have multiple test wich i have to run on a board, every single test give an integer value as output. I use a TDM file where i put all the value, coming from different board, in a single channel. Channel are already divided in group wich represent the type of the board were i run the test (part number). All the board have a serial number. Later, when i need to review the collected data, i need to know the value given by a single board, identify by it's serial number. So i need to add an identificator, maybe the serial number, to the value i store in the TDM file. How can i do this?

Thank you, Francesco.

Use another channel for serial number.  As long as it is an actual number, there shouldn't be any issues.

And so i can recover the value by its position on the vector, right? And if i have a serial number that is a text string?

A string can't be channel data.  So what you might have to do is make the serial number a metadata name and the value of that metadata the index of that serial number.

To be honest, I don't think TDMS is the right format for your data.  TDMS is great for waveforms.  But single data points, not so much.  What you really need is a database.
