Open valve digitally

[sheranko]

Ok, I am having trouble doing what I said I needed to do in the last post, Dennis can you help me out?

Do you want all of them to be the same state. In other words, all 8 on for a certain time and then all 8 off for a certain time? If that's the case, I wouldn't even use front panel controls. Just an array constant wired to the DAQ Assistant. Then a Delay function followed by another DAQ Assistant followed by another Delay.

This should work for my first experiment but I want to be able to hook up multiple valves and run them at different times, so I will need a time on and a time off for each one. Should I hvae the setup there you showed me but each one for a different channel?

[Dennis_Knutson]

Basically, yes.

Thanks for the replies - they are helpful.  I figure out my problem.  I am wiring global channel to physical channel but in fact all I need is the line constant.  I am attaching the screenshot of my vi here.
