VISA: (Hex 0xBFFF006C) An overrun error occurred during transfer.

[HarshRaj18]

Hi wise NI LabVIEW people,

I am getting the following error and I am a learner in LabVIEW so please suggest a solution.

Error - VISA: (Hex 0xBFFF006C) An overrun error occurred during transfer. A character was not read from the hardware before the next character arrived.

I am reading Temperature, Pressure and Flow value from a TSI flow meter. For your reference, I attached the vi that controls the flow meter.

I hope I could explain the issue. Please feel free to ask questions for more discussion. Thanks for your time.

No, you did not attach your VI to the message…

Read from VISA more often or request more bytes per read.

All the inportant stuff is explained in this excellent video!

Hi,

How do you do buffer flushes? I am also facing same type of issue but not able to resolve it.

Hi Raj,

please keep your discussion in one place…

Flushing the buffers is only a bandaid!

I repeat: all the important stuff is explained in the video linked in my previous message!

Hi GerdW,

Thanks for the video, I'll check it. I hope you can see the Vi now.

Hi Raj,

did you notice my signature line?

Could you please dowconvert your VI for an older LabVIEW version and attach again - I prefer LV2019 (File->Save for previous).

Do you have a link to the manual of the device you are trying to communicate with?  We need something to reference to make sure you are talking to it correctly.  I suspect you need to add a button to conditionally write your command and then still try to read every loop.  But, again, I need to manual to verify this.

Hi,

Thank you for your suggestions. Here is the manual of the instrument 4100.

On the page 7, it mentions that both the buffers are 50 bytes, if that is helpful.

Hi GerdW,

Here is the 2019 version of the vi for your kind look into it.

Nope, you saved for LV2023 now…
