Hi EneFoto,
as you told it's not possible to use Datasocket Connection feature from front panel because VI Logger publishes data over DataSocket that is a 2-D array of singles data type, whereas front panel DataSocket connections are looking for a 1-D array of data, and thus cannot recognize the data that is being published. So the solution is to use the DataSocket VIs instead of the front panel DataSocket connection.
You can find Datasocket examples searching from Help>>Find Examples in Labview.
However you have to use simply the "Datasocket Read.vi" function with the string "dstp:\\<remote PC Name>\<VI Logger Task Name>" as "connection in" input and a 2-D numeric Array as "Type" Input.
I hope this help you.
