Hi everyone,

I’m using an sbRIO-9638 with LabVIEW Real-Time, and I’ve configured a watchdog timer.
When the watchdog expires, I want the system to automatically restart my startup application.

I set my RT VI as the startup application in LabVIEW and deployed it successfully.
In the watchdog configuration, I selected “Restart LabVIEW Runtime”, but after the watchdog expires, the VI doesn’t start again.

I also tried rebooting the sbRIO manually — it reboots, but the application still doesn’t launch automatically.

Could someone please tell me what the correct watchdog expiration action should be, or what settings I might be missing?

Hi Ajay,

what's the point in creating multiple threads on the very same problem? (I merged them.)

The watchdog can be used to reboot the RIO automatically.

But when your application doesn't run on startup then the watchdog can't help with this problem!

You need to make sure your app is correctly set as startup exe, and you enabled the auto-start of that exe, and your exe is actually able to run…

This is explained in the sbRIO manual… (Or in some youtube videos.)
