Hi,
My hardware is a PXI-6723 with 32 AO, my software is LabView 8.6 my OS is Windows XP.
I would like to update the AO buffer at any time during the generation without interruption of it. I try to stop the task, to update the AO buffer and then to restart the AO generation but I get the following error:
Error -200288 occurred at DAQmx Write (Analog 1D Wfm NChan NSamp).vi:1
Possible reason(s):
Measurements: Attempted to write a sample beyond the final sample generated. The generation has stopped, therefore the sample specified by the combination of position and offset will never be available.
Specify a position and offset which selects a sample up to, but not beyond, the final sample generated. The final sample generated can be determined by querying the total samples generated after a generation has stopped.
Attempted to Write Sample: 0
Property: RelativeTo
Corresponding Value: Current Write Position
Property: Offset
Corresponding Value:
Task Name: Volt_Gen
I tried many things with the DAQmx Write property node but in fact, I do not really understand how the buffer works and how it can be properly updated !
Thanks for your help.
Eric
