Making a USB-6009 output a preset voltage characteristic

[aparker]

I'm trying to get my USB-6009 to output a preset voltage characteristic automatically. It should follow a preset function for a certain period of time (say 120 seconds) and then after that, return manual voltage control to the user. I've created a rough idea of what I'd like the desired voltage characteristic to look like in the image shown below. Thanks for your help.

How do you want to enter the desired voltage profile?  What do the VIs you posted have to do with your question?

voltron_simulated device Clk-Timed Loop_d11.vi is the program that I want to modify. Right now, the program has a slider bar that allows the user to manually control the voltage coming out of channel ao1. That's the part I'd like to modify. I looked in the DAQ assistant that controls the ao1 channel and I didn't see anything that would allow me to do such a thing. With regard to the other VI, Gen Voltage Update-1, that shouldn't have been posted. I should've posted the VI that I'm posting now because it is the dependency for voltron_simulated device Clk-Timed Loop_d11.vi

The slider simply produces a number. So what you want to do is produce a number which varies in time in accord with your profile.  You can generate this programmatically if you have a function of time repeseneting the votlages you want. Or you could create an array with the voltages and index through the array.  With the array method you could get the values for the array from a file.
