Error 0x80040311 -2147220719

Hi!

So 2 stations just got Error 0x80040311 -2147220719 after working well for a several years, as far as my Google Fu works i can say it's a rare error, i could only find 2 threads on it, the last 2 years ago.

Is there much else i can do but reinstall DAQmx and possibly reset MAX db?

Hi  Yamaeda,

Without more information it would be difficult for any of our forum users to say the exact cause of error. Reinstalling DAQmx would be a good start just in case its corrupted. Also your message suggests that you have been running the programme for a long time (several years) have you tried restarting LabVIEW. If this doesn't solve your issue it would be helpful to know details such as:

-What version of LabVIEW are you using

-What hardware are you using

-What changed on your system recently e.g a windows update or did you download any new software (even if its not LabVIEW related)

-Are you using any third party hardware or drivers

Kind Regards,

Bernadine

I seem to have solved it.

They haven't been constantly running for years, they're typically up for a week at a time, but the program itself is old, the latest version is ~1 year old so it's not a recent code change that's the issue.

What seems to have happened is a IT department update which created a VISA port conflict in MAX that then disabled a COM port. The error message in the program was as mentioned.

I've just fixed it over a remote desktop and on one computer i could access MAX and simply solve the conflict. On the other one the MAX db was corrupted so bad i couldn't access MAX-reset but had to use the external ResetMaxDb. After a MAX import of Tasks it seems to have solved the issue.
