enregistrement d'une entrée analogique lors d'un changement d'état d'une entrée numérique.

[jacob20]

Dans mon application, je dois contrôler si un manocontact de pression pneumatique est bien réglé. C’est-à-dire,  je dois visualiser sur « la face avant » la valeur d’une entrée analogique du module NI 9203 à laquelle une entrée numérique du module NI 9422 change de valeur (passe de 24Vdc à 0).

SVP, Je préfère un exemple pour mieux comprendre.

Hi Jacob,

Sorry it took me some time to respond but if you still have problems with this. I would suggest you take a look at the example i attached. You can also find this example with the NI Example finder because it comes standard with Labview.

There you will also find the description of what the example will do. But in short you are going to have to configure your analog measurement to be triggered on a digital edge change.

In the NI Example finder are perhaps also other examples that can help you. Try it out. You can find the example finder on the bottom right when you are in the getting started screen or when you are in a vi, go to help and then select find examples.
Once the example finder is open navigate to Hardware input and output -> DAQmx -> Analog Measurements -> Voltage, there you will find the example i attached with a description. Good luck and keep me posted.
