How can I get the actual value of 6071E analog output voltage?

[bartislartfass]

I'm trying to determine the actual output voltage of my 6071E analog outs without measurement. I have to avoid duplicate writing a high level if it is already set. The reason for this is because I write a special timed multichannel sequence for "set" and "reset" to the output. If it is already in the desired state the sequence must not be sent again. I could not find a property for this in the channel property node (using DAQmx 8.0) ...

UNfortunately there is no way to get this information from the DAQmx driver. You will have to store the last value you set the AO to in a variable or a shift-register, and use this variable/shift register to check the current stae of your analog output.
