Hi all,
I am using cDAQ-9137 to acquire some analog voltage on NI-9220. The acquisition would stop when the application receives a command via a TCP/IP connection and also via a signal wired to the PFI0.
I created an event structure to handle the software command. However, I am having a problem detecting a PFI0 signal and then generate another event to perform the same thing. Can you show me an example on how to do this?
Thank you very much,
David

Hello DucPhung,
I recommend you check out the following document: Configuring a Stop Trigger using NI-DAQmx for LabVIEW.
I believe the easiest way to implement this solution is using a stop trigger with your PFI0 line, and use the DAQmx Stop Task VI with your TCP/IP connection. That way the task will end one way or another.
Other more complex option is creating a digital input tas and using the Register Events to use it as a Dynamic event in your event structure, which perhaps is more complicated to do the task you have in hand.
All the best!
