[dazza]

Hey,just wondering if i can run a data acquistion program to get data from an instrument and make a change to an analog output device at the same time.Basically wot im doing is this,im reading a pressure from a gauge using AI, but wot i want to then is change a setpoint on another device and notice the change in the AI gauge.

Any help would be greatly appreicated

Hey Dazza,

All you need to do for this is simulteneous analogue input/output. This can be done easily in LabVIEW, by configuring the output channel and input channel parallel to eachother, and then begin the while loop with both a read and a write function in. The order of execution is controlled by the error handling string which is passed from each sub-vi to the next.

Check out these examples attatched below. These are part of the examples that ship with LV itself. I found these by selecting: LV help > Find Examples, then performing a search on the word: simultaneous.

Let me know if these help you out.

Ryan.
