generqte a PWM signal with LabVIEW using digitals outputs

hi i2dx, sorry to disturb you again.
Thank you again for your 50 Hz program, it's precisely what I need. But unfortunatly, it doesn't work yet. The problem comes from the link between NI-DAQmx and the PXI 6070E device. In fact, it works with the test panel, but I can't configure the VI "DAQ configuration" with LabVIEW, and when I lunch your program (or any other programs containing DAQmx VIs), the error 200220 occures. Have you ever had this kind of problem ? Isn't that a problem with software's versions ? (NI-DAQmx 3.1)
Otherwise, is it possible to create the same progam you have ever done (50Hz) but without using DAQmx VIs, just tradionnal DAQ VIs ? (I don't want you to create it, I just want to know if it's feasible in theory).
Thanks
Have a nice weekend end.
