There is a network watchdog present on the cRIO. The system watchdog has everything to do with network communication.

A specific quote about the system watchdog from that article:
System Watchdog
The system watchdog (always enabled) ensures the wireless and Compact RIO system are behaving properly. This is a watchdog built into the Compact RIO FPGA that is fed TCP packets through the Ethernet connection (wired or wireless) from the driver station to the cRIO-FRC. This happens by default and requires no additional setup from the user beyond normal IP address setup of the cRIO and driver's station. If anything disrupts the connection between the drivers station and the cRIO (such as a loss of wireless network connection) the FPGA turns off all PWM and actuator outputs. This immediately stops the robot and prevents a run-away robot. Additionally, the system watchdog will trigger if the competition dongle is not attached to the drivers station in the enabled position. Teams do not have any way to access or modify this watchdog. Ideally, this watchdog is entirely transparent to the user and just works.
