Hello,
DaqMx Vis only works when the NI Device Loader service is running.
If this windows service is not running, DaqMx functions generates error like "Device not found..., undefined board, undefined hardware ...."
For some week, i get such an error and it take me a long time to point the real cause !
A windows or software update had changed the service startup sequence ... and the Ni device loader service was no more starting.
The solution to this problem was to configure the NI Device Loader service in order to force restart on start failure.
It should be nice if daqMX functions could generate the "right error".
An error like : "Ni services are not running please check their current state ... The DaqMx devices could not be accessed when Ni Device Loader service is not running".
This problem also generates problem in MAX ! (The device treeview takes a long time to expand ... and the device autotest fail)
Thanks for kudossing this idea which could help understanding windows services problems.
