Slow Power Ramp Up

Hello, 

I have a high power voltage supply.  I need to slowly ramp up the voltage of the power supply, say 20 V per second, up to 1000 V.  

I can control the power of the supply manually. For example I can set the power supply to be 100 V run the program, then 120 V run the program, etc. Is there a way to have the program do this automatically?

Attached please see my code.

Thanks for the help.

Respectfully, 

Andre
