"Watchdog" functions; monitoring of the serial data flow
If, once this function has been activated (see NAMUR commands), there is no retransmission of the command from the computer within
the set time ("watchdog time"), the heating and stirring functions are switched off in accordance with the set "watchdog" function or

The data transmission may be interrupted by, for example, a crash in the operating system, a power failure in the PC or an issue with the
connection cable between the computer and the device.

safety speed limit and the temperature target value is changed to the WD safety temperature limit value. The warning WD is displayed.
