Some basic questions...

[aqua_life]

Hi,

I am doing a simple program in Labview, but I have some doughts...

- My program has 2 analog inputs, so I have put in the front panel 2 DAQ channels. Is this enought to read them?

- I want to read this 2 values and then save them to use later (in the next cycle). How can I make this?

- As I want the program to read the 2 analog inputs from 200ms to 200ms I have put in the block diagram a Time Delay. Is this good?

Thanks for your help.

Hi aqua,

some basic tutorials are to be found here Have you looked at the examples coming with LabVIEW?

"in the front panel 2 DAQ channels. Is this enought to read them?"

Surely not. You need some DAQmx-Read-commands...

"use later (in the next cycle)."

Use a shift register...

"a Time Delay. Is this good?"

What could be bad with a Time Delay?

To your DAQ question:

Make a single (1) task for both AIs. After the read DAQmx, use a index array function. Resize the IndexArray to show two indices, don't wire the indices. They are automagically set to index 0 and 1.

We can point out more issues when you post code/screenshots.
