Prob to analog output and graphical visualization

Hi, i did make the modifications and now i'm using a timed loop. It is working perfectly and i now have the sampling frequency i want. The file result is TextFile.txt".
My problem is now that my analog output is not working and so the analog input (directly linked) which must be recorded is not good. The analog ouput corresponds to the digital ouput triggering my vibrators. To ouput an analog i'm using a case structure linking one digital to a voltage value like 1 for a digital of 253.
But when i'm watching  at the graph or in the text file, the voltage do not correspond to the one i'm outputting.
Why ? Can you somebody help  me ?
is there other things wrong in my VI ?

thanks

seq is the file to open for the second timed loop, this the is the sequence for the digital ouput.
Test is the VI.
