generqte a PWM signal with LabVIEW using digitals outputs

I have checked out, Device 1 is the correct nomber for the 6070E installed on my computer. I looked at the error codes, but it didn't help me more.
I 'll try to uninstall all and install the new version you gave me. Thanks again, I'll tell you on monday if it's worked.

hi i2dx
I am installing the last NI-DAQmx version, however, it's important for me to know if the same PMW signal is feasible with tradional DAQ VIs.
thanks

yes, it is possible to programm the PWM with traditional DAQ, but I would not recommend it, anyway!

ok, I have installed the last version of NI-DAQmx but it doesn't work neither. I don't understand, I can communicate with the 6070E card using the Measurement & Automation's Test panel without any problem. But it doesn't work with Labiew. I tried to configure it with DAQ assistant but I always received the same message "No supported devices found". You have to know that I use a remote system, with PXI chassis. I attached a screenshot of my MAX page, maybe you could see where I have done a mistake.

if the device is in the PXI, you have to switch your traget to the PXI-System and work with the RT-Module ...

Thanks, I found the switch and I can now communicate from LabVIEW to my PXI-6070E card through the digital output. But it still doesn't work with both your programs because of a sample problem. I attached the error message box. So, I' d like to know if you have ever tried your programs with DAQ devices, and if it worked. Which devices did you use? And which version of LabVIEW?
Thanks again

i have tested it with a M-Series NI-PCI-6251,

i used LV 7.1 for this example ...

Hi i2dx, it's me again.
Last time, I had told you I had an error (-200077) and I found what was the problem : your program can't work with my 6070E because, I have found a exemple in LabVIEW (Cont Write Dig Port-Ext Clk.vi) with use the same VI as your program, and I get the same error. I ckecked out, the 6251 card that you used is in the list of hardware compatible with the exemple, but not the 6070E card. So I have to find another solution to generate a PWM signal to the DO line. I would like to know if you think that I can use the exemple "Write Dig Chan.vi" in replacing "Data to write" by a waveform which will be a PWM signal waveform and how can I do that ?
Thanks

sorry, but this wont help.

take a look at the specifications of the card and you will see, that the PXI 6070E is only capable of 50 Hz DIO Input / Output.

And the write Single Chanel Solution will be slower, because it's software timed and you get an maximum resolution of 1 kHz, but it's not recommended to use software timing at this "high" sample rates anyway.

it seems, that you are not able to get this running with your card. The new M-Series DAQ-Boards are capable of 10 MHz DIO operations ... maybe you should contact your local NI sales representative?

Hi i2dx, I hope you're still here because I have a problem and I need your help again. that's about the VI you gave me last time (DIO PWM 50Hz). As you told me, I had troubles because of the incompatibility of my hardware. But know, I received a new PSI and a new DAQ card ysterday. This is a PXI8187 embedded controller with a PXI 6229 multifunction DAQ. But I still have a problem, a new one. The error code is -200462 and it appears after the "create task VI" (see attached picture). Actually, it seems to be a software problem in opposition to my previous problems. But you told me, this VI works with you, isn't it ?
Please could you help me again, I am desperate 'cause of this project.
Thanks.
