Reading the status of the output voltage

[Ibn7alal]

Hello, 

I am using a 6703 card which is a static analog voltage output card.  At some point in my program, once I write to the output voltage channels, I would like to read back this output voltage from the card.  How can I do that?  Is there a property node that spits out the value of the voltage output? I tried using the DAQmx read functionality, but without any success.  I also looked at the possiblity of using the DAQmx Channel property node, but I couldn't find what I am looking for.  Any ideas?  Thanks in advanced for your kind help.

Best wishes

Do you want to read back the voltage setpoint that you wrote?  Or, do you want to measure the actual voltage?

Hi, 

Do you want to read back the voltage setpoint that you wrote?  Or, do you want to measure the actual voltage?

Yes, I would like to read back the voltage setpoint.  I do not need to measure the voltage.

Hey Ibn7alal,

Unfortunately, since the 6703 is an AO device only, it isn't possible to read the internal value of the AO as this would require an AI channel. This forum may provide further information for reference:

If you simply wish to be able to access the value that you sent into the AO, then you may consider a local variable. Hope this helps!
