Input Trigger - Starting a VI after receiving signal

[Daniel42]

Hello,

I would like to know if I can trigger a LabVIEW VI to start running after receiving a current signal. I have a NI 9208 current input module connected to a cRio-9074. I don't know what to add to my VI to make this work. Could someone help me with this, please? Thank you for your help!

Best Regards,

Daniel

Hi Daniel,

trigger a LabVIEW VI to start running after receiving a current signal.

Sounds like those 3 simple steps:

- read in signal in a loop

- end loop when "trigger condition" is met

- run your other VI…

Which of these is a problem to you?

Hello,

Thank you for your prompt response. My problem is that I don't know where to find these commands (I don't know the name of the function that I would pick from the functions palette). Could you help me with this? Thanks!

Hi Daniel,

in this case I suggest to take the free beginner tutorials to learn LabVIEW and to handle the cRIO programming!

You may start here and here!

All you need to start is a (while) loop with a ScanEngine IONode inside to read your signal…
