Error 1073807253

[Student81]

Hi guys!

I´m back with another question. When I try too recieve my my signal in the waveform chart a get an error It says: "Error 1073807253 occured at VISA Read in Basic Serial Write and Read.vi Possible reason(s): VISA: (HEX 0xBFFF006B) A framing error occurred during transfer". I recieve the signal but every now ang then this messeage comes up. I read from the serial port. I´m using the example "Basic serial Write and Read" from "Hardware Input and Output". I´ve tried to put a flush buffer in this example after the Visa configuaration but this won´t help. And I´ve already checked that the configuaration (baud rate, stop bit, flow controll etc) is matched  I hope someone can help me.

Thanks

Hi,

This might help explain your problem. http://digital.ni.com/public.nsf/allkb/F3E0621CB71AA16786256F970000FC57

You will probably have to split up the VI's so that you only configure the device once then do you writing and reading.

Hi

What do you mean with:"split up the VI"? I´ve already tried to put the flush buffer after the dely so this doesn´t help my problem...Any other ideas?

Thanks

Hi,

Sorry, what I meant to say you will have to resturcture your main VI, eg

Begin

      Do Config

      Begin Loop (until stop press or error occurred)

          if Send Button pressed

               Perform Send

          end if

          if bytes at receive port

               Perform Read

        end if

     End loop

end

 Hope this explains it

Hi

Ok...let my explain to you of what we are trying to do..

we have a signale comming through the serial port (this signale is good and confirmed so the problem is not there), anyway,,,, we would like to recieve the signale in LabVIEW and then preform some signalprocessing.  So the problem is when we recieving the signale we gett a framing error massage. WHAT IS THE REASONE?

Thanks

Hi again...I send you the code and give you a picture of the front panel...

Thank you for your time!

Hi.

We´ve solved the problem...We putted the flush buffer directly after the property node....And that was yust what you told us...but instead of puting it ther, we putted it directly after the delay...

Thank you for your help!

Hello Student81,

can you post a picture of the code, where it is possible to see the solution of the problem with error -1073807253? At the moment I find with this error, too.
