Exception 0E

Hi there.

I�ve been having problems with a SCXI-1000. I am using a SCXI-1000, with a SCXI-1200 (controlling the chassis), a SCXI-1120 and a SCXI-1163. I developed a program in LabVIEW to take temperature readings (through the SCXI-1120) and send digital signal through the digital outputs of the SCXI-1163. The SCXI-1200 is only used to control the chassis.

The problem occurs after some time running (which is variable, it can be one day, two days or a few hours), when that infamous blue Windows screen is displayed with the following message (translated from portuguese) :
" Windows

An Exception 0E occurred at 0028:C980C906 in VxD NIDAQK(01) + 00007906. It was called from 0028:C23DA3D0 in VxD NIPALK(01) + 00026330. It may be possible to continue normally. ..."
Hitting any key the program continues normally, and at a random time later, the problem repeats.

Let me trace the history of this development.
I was having a lot of problem using the SCXI. After some time, the data acquisition always died with a timeout error message.
I then tried to disable every energy saving feature on both BIOS and Windows. Then the program was working fine for a few weeks, until the problem of the timeout started again.
Then I tried to reset the SCXI-1200 everytime a timeout was detected. Again, it worked for a few weeks, but then that blue screen described above started to appear. When this blue screen problem appeared, I was using LabVIEW 5.1 with NI-DAQ 6.9.1f28. After some unsuccessful attempts, I decided to install LabVIEW Base 6.1 and NI-DAQ 6.9.2 over the previous installation. Again, it didn�t worked. Finally, I tried to change the computer. I installed on this new computer LabVIEW 6.1 and NI-DAQ 6.9.2, and the same blue screen problem still happens.

I am in a hurry to finish a project and this problems won�t let me do it.
I just don�t know what else I can try. I am sending attached a stripped version of my program (only with the DAQ part and a few variables). The main control routine is the daq_control.vi. There are the workarounds I mentioned to get the best reliability from the system.

PS : The first problems I described were successfully fixed disabling the Energy saving and reset the SCXI-1200 whenever necessary. Only the blue screen problem I wasn�t abel to fix yet.

Hello Willy,
When you encounter a system crash while using National Instruments products (for example if the crash only happens when you are using NI hardware and/or software or the crash indicates a software module named "ni..."), I strongly recommend that you contact National Instruments Technical Support as they are best prepared to assist you in resolving this type of issue. Unfortunately support for the 1200 series has been dropped from NI-DAQ 7.0, so upgrading to NI-DAQ 6.9.3 seems to be your only hope. If that still fails, then I would recommend contacting National Instruments Technical Support at http://www.ni.com/ask to see if any other solutions or workarounds can be determined.

Sincerely,
