Rif.: Problem with Toellner Drivers

[domcorrado]

Hello. I have this VI where i use a Toellner TOE8870 driver to set voltage and current and then read it. Now this is my problem: wether i set my output to be ch1 or ch2, when i read it its always displayed as ch1, and ch2 values are always 0. Could this be a driver problem? or what could this be?

Im using labview 2021 sp1

Hi domcorrado, 

could you down version your code to LV20, my labview version ist LV20, can not open your VI.
