Communication with CompactRIO

[a.luque]

Hello,

I have an application in LabView and I need that before starting the application, check that I have communication with the compacRIO, if not, I should avoid this startup, but if the communication is correct, you should start the program. Is there any function to do that check? Or some way of doing a "ping" to the IP of the CompactRIO and getting an answer, knowing that the communication is correct?

Thank you!

Hi a.,

the RTExe on your cRIO should run anyway.

So you can have your host PC exe to start a network communication with your cRIO exe (where the needed code is implement!) and when your cRIO answers the host PC exe can go to "normal" working mode.

I use UDP communication with my cRIO devices, mainly based on the UDP examples coming with the example finder in LabVIEW…
