check the progress of DAQmx waveform output

[MadMark666]

Hello,

I'm outputing a waveform via DAQmx. The waveform is a decaying sine wave over a variable time period, normally 10 seconds or a number of minutes. I display the waveform to be output on a graph display but I would like to give the user an indicator as to the progress of the output. Is it possible to get a property node to tell how many seconds into the total output you are?

I have looked at the properties and can find nothing that looks like it could do this.

I use the 'DAQmx Task Is Done.vi' to check when it has finished within a loop.

Thanks in advance.

Okay I'm a twit .

All you need is the property: DAQmx Write>TotalSampPerChanGenerated. This tells you the number of samples output of the input Waveform at the time you request the information.
