5.4.16 NSIGWDG
It is possible to configure a maximal time without telegrams from the master before the
Modbus board triggers the configured signal loss action (busfault reaction). By default no
timeout is set.
Register NSIGWDG holds the signal loss watchdog time in milliseconds.
0 = Watchdog disabled (default setting)
1 ... 65535 = 1ms ... 65535ms
If the Modbus board is not addressed with telegrams from Modbus master for this time the
watchdog triggers and the signal loss action is executed (see NSIGACT).
