How do I make my waveform send one point per iteration in a loop?

[lhoising]

Hello,

I am trying to create a demonstration/lab for a future course at my university.  I am trying to send data from a wind turbine to a third party DAC in order to run a motor.  I have found out that when I send a wave form to the DAC I must send one point per iteration if I use the arbitrary signal generator.  I would like to be able to send a file to the DAC without manually loading it as the arbitrary signal generator does.  I was wondering how to send the data using one point per iteration using the build waveform or other waveform function that can have the waveform built from a file that is added on the front panel.  I am using labview 8.0.

Thanks,

Laura

Maybe I am asking the wrong question.  Maybe I should be asking why it is that when I send a waveform to the the DAC (using active x controls) the signal that is sent to the DAC is just the final value.  I probed the wire connected to the data input of the DAOUTPUT node and it shows the entire waveform graph and not just the last value.

Thanks,

Hi Laura,

I'm a little confused.  Could you post your VI so I can take a look at it?  It may be the case that this is just a limitation of the device driver that you have.  However, if I see something wrong with your VI I can help you out.
