How to Control the Valves and Pump with Labview?

[KRAZE4LV]

I have started a new project where I have to control the valves operation through Labview 2009,using PXI 1031, NI 5105(Digitizer) and NI 6251(M-series DAQ).

The valves I need to control using the labview are:

a) Pressure Reducing Valve (open & close)

b) Remote control Valve(On & Off) with in-built actuator

c) Flow control valve(open, semi open, partially open, semi close, partially close, fully close), 1%, 2%, 3%..etc

d)saftey valve (opening closing depending on increase in pressure from certian limit)

I hav eto control

a) Hydraulic pump operation with in built gear-box

Please let me know, how should l develop the VI for all? How to get started?, any helpful links? If there is any example code?

Its little urgent !

duplicate post

Don't post the same question to multiple boards. It's VERY irritating.

That message was for Anita..I think we have a right to post our query to the LV experts, until we find a satisfactory solutions.

If you feel irritated than pardon me.

The post was in no way intended for 'Anita'. You posted the exact same question multiple times and that would be considered rude in any forum. It is a waste of everyone's time. Most of us are volunteers, you know. Wasting the time of the LV Experts is not a way to get your question answered by a LV expert. I don't intend to spend any time on this or further questions of yours.

OP also has no issue with PM for help with this issue.

p.s. Dennis, he said "Experts", so technically, no time wasting has occured.

KRAZE4LV,

As far as setting up your system goes, we do have many good examples. You can find a few by going to Help>>Find Examples in LabVIEW, and then looking under the Hardware Input and Ouput folder under DAQmx. There are also some community contributed examples at ni.com/examples.

And although this tutorial is a little old, you may find it useful - Complete Industrial Digital I/O and Counter/Timer Tutorial.

If you have any more specific questions, feel free to post them on the forum.
