200996

[phuech]

Hi I converted DAQmx assistant (coversion attached below). I get the following error:

Error 200996 (DAQmx Write Wfm NChan NSamp.vi)

Possible reason(s):

Measurements: Data Transfer Mechanism is not set to Programmed I/O, which is the only value supported when the Sample Mode is Hardware Timed Single Point.

Set your Data Transfer Mechanism to Programmed I/O or change the Sample Mode.

Property: AO.DataXferMech
Corresponding Value: DMA
Property: SampQuant.SampMode
Corresponding Value: Hardware Timed Single Point

Task Name: _unnamedTask<12>

I have not touched the above vi. Could someone tell me how to change one of the above parameters? Could this error occur for another reason, something I inadvertantly canged?

Hi Phuech,

Please can you tell me what DAQ card you have?
Also the code you sent doe not look as if the DAQ assistant created it and that was it; you must have modified some of the original code.

The DAQ assistant for a simple AO operation will look like DAQ Assistant2.vi,
The DAQ assistant for a multiple AO operation will look like DAQ Assistant3.vi.

Please can you tell me what you have done to the generated code, and what you want your code to actually do?

Hi,

Thanks for your reply, I managed to fix it in the end though. I can't quite remember what the problem was. I was working with a PXI-6723 AO card.
