Watchdog enable
bit 8 Setting the Watchdog enable bit to “=1” causes the
Watchdog function to be enabled; setting the
Watchdog
enable
bit to “=0” causes the Watchdog function to be
disabled. When the Watchdog function is enabled, if the
device does not receive any message from the Server within
1 second, the system forces an alarm condition (the
Watchdog
alarm is invoked to appear as soon as the
Modbus network communication is restored). Watchdog
function is a safety timer that uses a time-out to detect
loop or deadlock conditions. For instance, should the serial
communication be cut off while a command is still active
and running Watchdog safety system immediately takes
action and commands an alarm to be triggered.
