Hi malayalam,

  Ofcourse you can control valve while acquisition is going on,but to have proper results,you need to code some logic and use proper datacquisition techniques.Please refer to LabVIEW programming manuals available on ni.com.

Thanks and regards,

srikrishna.

can you please give some example code

Thank you,

what kinda acquisition you want to do and what should be outcome, I have answered another post of yours, are both same post or is this any different?

[malayalam]

i want to do the automation  which will acquire the pressure as inpressure reaches 250 bar valve should closed and lock up for 2 sec and the open.and once pressure reaches 235ar it has to closed for 2 sec and then open this process has to be repeted till atmosph pressure reaches.

this is what i want to do in auto loop. now we are doing in manual

There is nothing wrong in your 2 seconds logic, See the attached program, this is simple on-off reaction based on your pressure output. I assume that transducer is 1-1. YOu can modify the VI to suit your app.
