invalid buffer error in traditional DAQ

[dragondriver]

Hi all,

  I have a question regarding the invalid buffer configuration for analog output on 6713Ecard. I think this might be too old to find a support but I still want a trial. I have a 6713card, Labview 7.1 and traditional DAQ 7.2 installed. I am using the "AO Generate Waveform.vi" to output the multiple samples (waveform) to one channel via PCI-6713E but it always report "10687 AO buffer error (invalid buffer or buffer not configurated)". I also tried to use use AO CONFIG to configure the device but it doesn't help. But if I use the same code but output to a 6711 card, nothing wrong. I think using AO Generate Waveform.vi is pretty simple, we set the device number, channels, update rate and the waveform, there is no option to configure the buffer so I don't know why it comes out that error code.

Since you have LabVIEW 7.1, why are you bothering with traditional DAQ instead of DAQmx. You would actually be able to get support.

The code is pretty old and becomes part of a big program, I currently cannot upgrade to DAQmx 😞

The only reference to this error I could find is in http://digital.ni.com/public.nsf/allkb/862567530005F09D862567CF007D8BDD. You could also post your block diagram so that other persons have a better look on how you program it.
