Error 200459

[abcdd]

Hi,

I am facing one error while creating a VI for signal acquisition.

I have attached a screenshoot of my VI

Error code is 200459

It says "Measurements: Write failed, because there are no output channels in this task to which data can be written."

Please suggest me solution to this problem.

Thank you.

Hi abcdd,

mind to use the cleanup button before posting pictures of your VI?

Hmm, let's think about your pic...

Ok, you want to output voltages. Fine.

You select "AI voltage" for setting up channels. Hmm, "AI" means AnalogInput. Hmm, you want to output voltages???

Further: you select "dev/ai0" as channel. Hmm, you want to output voltages. Hmm, on an AnalogInput channel???

Now you wonder on that error message? Really?

Oh sorry, when re-reading your post I notice you want to acquire a signal. So why do you use the DAQmxWrite function when you want to Read a signal value?
