5.1.3 Watchdog function
The Watchdog function monitors a device connected to an output and restarts it if necessary.
The device needs to be accessible over the network using the ping command (it needs to have an IP
address assigned). If the monitored device is inaccessible, the specified output is power-cycled.
A device is considered inaccessible if it fails to respond to Ping requests within a specified interval.
(Ping is a service that allows checking the connection between two network interfaces.) To avoid
infinite switching if the monitored device is faulty, the maximum number of restart attempts can be
set.
