I think it's in the start communications vi (called by Robot Main).
The default is 1000 ms.

I don't have a LabVIEW computer up to check.

P.S.
DS Occurrence (1 second timeout according to old CD post) in Get Robot Competition Mode vi sets mode to "Finish" and the Robot Main vi case statement causes the program to exit. That sounds like an eStop though. I don't remember how it all fits together without walking through the logic again.

These are just shadows or reporters of the System Watchdog though, not the watchdog itself.
Ultimately, I'd expect the duration and mechanism must be embedded in the protected vi's and the FPGA image which we don't have access to.
Probably PM Greg.
