How do i disable a polling daq process when a continuous one is running ?

[French LVer]

Greetings from France,

I'm almost new on NI forum and i already need your help 🙂

I'm currently on a software specification using data acquisition based on Labview.

Briefly, i have two daq processes running in same time on same channels :

- a polling acquisition (one sample per channel) recording data each 10 minutes,
- and a continuous acquisition (11 channels at 1kHz each) triggered by a digital input's edge front during near 10 seconds (retriggerable).

My question is :

- Is there a way to disable polling acquisitions when daq card is currently working on a continuous one ? (i assume NiDaq's error will occur if not disabled).

If not, i will have to continuously acquire channels and do triggering action by software.

Without daq hardware available right now, i can't test it by myself so i ask you all for some advice 🙂

Merci beaucoup pour ta réponse ManuelR

Je pense m'orienter vers une acquisition continue des 16 voies à 1 kHz puis d'effectuer les post-traitements de manière logicielle.

Cordialement,
