J'ai l'erreur suivante venant de mon DAQ :
"
L'erreur -200022 s'est produite à : DAQmx Start Task.vi:7220001
Raisons possibles :
La ressource demandée par cette tâche a déjà été réservée par une tâche différente.
Périphérique: cDAQ1Mod2
Nom de tâche : _unnamedTask<FC>
"
Cette erreur apparait lorsque je lance un autre VI (voir l'image - com10) qui fait appelle à une instrument connetecté en USB (port série)
Si je ne lance pas ce VI, mon autre VI avec le DAQ fontctionne normalement
Mais c'est embêtant de ne pas pourvoir lancer mes deux VI en parallèle
Merci d'avance pour vos suggestions

May be your DAQ device does not support more than 1 task to run at a time. The first task that runs has already taken control of resources which are also required by the second task.

Thanks for your answer, but no it not a question of number of tasks.
Because i don't have this error message when i run this VI alone.
It appears when i start a second VI which uses a usb communication by serial port.
I have the feeling that when Labview use the DAQ , it has an problem for the other serial port....
So i haven't still solved my problem
