GPIB drivers running simultaneously in a sub-vi ??

[Dennis_Knutson]

There's really nothing there in that program. I have no idea how you have to program the controller. Do you just pass it a set point and ramp rate? You have nothing there to read the current temperature. That would also be a controller function. You have nothing there for a delay and checking for a stable temp. That could be a loop with a shift register that compares the current reading with the previous reading. Exit the loop when the delta is within some sort of range. All of this code would be done before you call the VI that you posted.

If you want to repeat, then you could wrap all of this inside a for loop. From outside the for loop, connect an array that has your different set points and an array that has your different ramp rates. The for loop with autoindex the arrays and it will run each segment that you define.

I did not put my main VI there, because you probably don't have the drivers i used, installed in your pc. What i attached was a little scratch, in order to explain me better, i'm new in LV and i'm even more in GPIB conections..so i prefer that people, send me some short example vi's that will lead me..instead of a text tips, that some of them i can't even understand or i don't know where to begin.

Still, many thanks for your help. I will try to decode what you just told me to do.
