"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 are changed to the set target values.
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 table between the computer and RET control-visc.
"Watchdog" - mode 1
If there is an interruption in data communications (longer than the
set watchdog time), the heating and stirring functions are switched
off and ER 2 is displayed.
"Watchdog" - mode 2
If there is an interruption in data communications (longer than the
set watchdog time), the speed target value is changed to the WD
safety speed limit and the temperature target value is changed
to the WD safety temperature limit value. The warning WD is
displayed.
