Error -1074126826 occurred at niSwitch Initialize.vi

I'm getting an intermittant error with my switch card:

Error -1074126826 occurred at niSwitch Initialize.vi
Possible reason(s):
Max time exceeded.

Device: SWT1-DUTSwitching

Status Code: -200221

It happens about 25% of the start-ups (fixed with a restart).  I can't find the error codes in any documentation - has anyone got any ideas please?

Hi crelf,

May I ask what version of the NI-Switch driver you are using?  If you are not using NI-Switch 3.3.1, the solution to your problem will be to upgrade to this version (or the latest available).

Recently, we found that a hard reboot could cause intermittent switch module operation similar to your description.  It didn't always occur on the same switches every time, and a soft reboot would often fix the issue.  This issue was noted to occur with DAQmx 8.1 / NI-Switch 3.1 and DAQmx 8.3 / NI-Switch 3.3 driver versions.  We incorporated the fix with NI-Switch 3.3.1.

Please let me know if you have further questions or if this does not resolve your issue!

G'Day Chad - thanks for your answer: after several weeks of testing I haven't had the error message since I upgraded to 3.3.1!  Well done 🙂
