error 2147220719

I have a compiled LabView 2013 dll to read and write to a USB daq 6501. This works well until I get error -200088 ... see

https://forums.ni.com/t5/Digital-I-O/Error-200088/m-p/3097920/highlight/true#M19785

Then after the -200088 error I then restart the program and then get the error 2147220719.

It would appear that the original error -200088 occurs when reading/writing to a specific ethernet device (not DAQmx) inbetween reading and writing to the Daqmx. This I am guessing ethernet traffic upsets the tasks in MAX somehow.

Then when restarting the program and trying to configure the ports again via the dll I get the error 2147220719.

MAX:  (Hex 0x80040311) The client process has been disconnected from the configuration server. If this problem persists, please note the steps you performed that led to this error and contact technical support at http://ni.com/support.

Task Name: _unnamedTask<5> DIO24 DAQmx  Device 1

 

See attached NItrace file

I am guessing ethernet traffic upsets Max tasks somehow; is there a fix for this error?

NI Daqmx 14.0

Max 14.0

Labview runtime 2013 sp1

Windows 7

Looks similar to a problem we have encountered, although using XP.

Seems you never got any response? Did you find a solution?

I have not had a reply from this. All I know is that the daqmx & visa use a NI server that runs in the background of windows. This NI server uses some of the (65000 plus)ports that windows has for TCP/UDP coms. When another third party program that uses some of these ports then closes some of the ports that the NI server is using (whether it needs to or not) it causes the daqmx/visa errors giving the error code 2147220719.

I think the only solution is to find out (from NI?) which specific ports do the daqmx/visa NI server use, then try and make sure the third party program does not close these specific ports.

I am hoping someone from NI can tell us which ports the NI daq/visa server actually uses in Windows; no responce as yet.

 

regards

OK thanks. Turned out our problem was not related to yours at all, I have no clues for you.

Good luck...
