4 analog signal to read

[Newbie92]

Hai guyz,

How do I configure my DAQmx or coding so that it would be able to  read four signal at once. Im trying to read 4 analog voltage signal from my sensor. I appreciate any help.

Don't make it so complicated! All that you needed is a single task with one Create Channel, Timing, and DAQmx Read. The channels can be selected by clicking on Browse or entering Dev1/ai0:3. You then change the DAQmx Read to N channels.

Hai Dennis_Knutson,

Could you show me the code example for it?

You've got the code. You just need to delete the extra tasks you have. Look at the examples as well.

Hai Dennis_Knutson,

I tried what you recommended but I don't know how to connect this new Read task to the multiple formula block. One more thing, I forgot to mention that I want it to take the reading simultaneously from the 4 different sensors I've placed. Can that be done as well in the method you recommended above?

Could you be kind to show me how it is done using the code I've attached?

Anyone?

Hi Newbie,

Dennis told you what to do. Have you even tried to change your code?

When you need examples: open the example finder! Look for DAQmx example VIs showing how to handle more than one channel…

Hi GerdW,

I did try to find example in the Find Example in help but can't find one. Maybe I missed them. If you have one that is similar I'll be glad to study it. The attachment I sent was the unedited one. Here I'll show you what I tried. I got stuck on how to set the Reader task. Sorry for posting the wrong code.

Regads,

Here's a quick example.
