trigger mass flow controllers using a timed loop

[Vikrantrai01]

Hi,
Here is my question. Any kind of help will be appreciated.
I have a mass flow controller (MKS 647B) and have the drivers to do certain jobs such as setting up set point and manually opening or closing valves. But i need to open and close different sets of valves at different time intervals. For example, i want to open channel 1 at t=0 then close channel 1 and open channel 2 at t=10 sec. I am new to labview an can think of only one option. Generate a wavefront for dt=10 sec with output as (0-1-0-1) and even I cant implement it. If someone can help me out with this that would be great.
Thanks,
Vikrant

Hey Vikrant,
         There are numerous ways to accomplish this.  The easiest would probably involve using a timed loop with a case structure.  Send the iteration count to the case structure, and open and close valves based on how much time has elapsed.  If you'd like some simple example code, I could post some, but you'll probably get more help on this particular issue if you post in the LabVIEW forum instead of the counter/timer board.  This seems like more of a LabVIEW code issue than a hardware issue.
