Modbus TCP Connection Watchdog Register
The 0xFA04 register contains the time for the Modbus TCP connection
watchdog. Time base is 10 ms. This enables the time to be set up to 655350 ms.
If the register contains a value > 0 s when a new TCP connection from a Modbus
master is accepted, the watchdog for this connection is started. Later changes to
the register have no effect on the monitoring of existing connections. If the
watchdog is started and no telegram is received from the connected Modbus
master within the set time, this connection is closed from one side with a reset.
