hi I am very new to labview, as a part of an experiment i need to control an agilent N6700B mainframe voltage controller using labview. I had established all the comm using GPIB . At the moment I am able to control the output voltage by using the attached labview program (this is a modified version of the example program i got from agilent). Whenever i give a voltage input in labview (marked as red in block diagram) I am getting the same voltage at hardware output.
Following are my questions
1) how I can change this manual voltage entry to an automatic mode . For example when i click run output should change to 5 V then without pressing anything it should change to 15 V after some seconds,later change to another Voltage.
2) when I press stop ,labview is stop working.but the hardware is stillgiving an output voltage, how can i reset my hardware (change voltage to zero) by pressing stop button
3) this program iscontrolling only one channel of my hardware. my hardware has multiple channel outputs. How I can controll all simoultaneaosly . I tries to copy and paste the block s to create another branch. But allchannels not working when I did so.
My quistions might be silly as I am really new in labview. But it will be really helpful if you can give a hand
