NAMUR Instructions Function
IN_NAME Input description name
IN_PV_X Reading the real value
X=1;2;3;4;
IN_SOFTWARE Input software ID number
date, version
IN_SP_X Reading the set rated value
X=1;2;3;4;6;12;
42;50;52;53;
IN_TYPE Input laboratory unit ID
OUT_NAME name Output description name. (Max. 10
characters, default: KS3000 ic)
OUT_SP_12@n Setting the WD safety temperature with
the echo of the set value
OUT_SP_42@n Setzen der WD safety speed with
the echo of the set value
OUT_SP_X n Setting the rated value to n
X=1;2;4;50;52
OUT_WD1@m Watchdog mode 1: When a WD1 event oc-
curs, the heating and shaking functions are
shutdown and message PC 1 is displayed.
Set the watchdog time to m (20...1500) se-
conds, with echo of the watchdog time.
This instruction starts the watchdog func-
tion and must be sent within the set
watchdog time
OUT_WD2@m Watchdog mode 2: When a WD2 event oc-
curs, the speed setpoint will be set to the
WD safety setpoint speed and the tempera-
ture setpoint will be set to the WD safety
setpoint temperature. The PC 2 warning is
displayed.
The WD2 event can be reset with OUT_
WD2@0-resetting also blocks the watch
dog function. Set the watchdog time to m
(20...1500) secondes, with echo of the
watchdog time. This command starts the
watchdog function and must be sent
within the set watchdog time.
RESET Switching off the instrument function.
START_X; X=1;2;4 Starting the instrument's (remote) function;
(display additionally: PC)
STATUS Display of status
1S: mode of operation A
2S: mode of operation B
3S: mode of operation C
S0: manual operation without fault
S1: Automatic operation Start
S2: Automatic operation Stop
(without fault)
(without fault)
STOP_X Switching off the instrument - (remote)
X=1;2;4 funktion. Variables set with OUT_SP_X are
maintained.
Contains the instruction RMP_STOP.

"Watchdog" function, monitoring the serial data flow
The following applies to situations where the watchdog function
is enabled (see Namur instructions). If no new transmissions
of these commands from the PC take place within the preset
watchdog time, the heating and shaking functions will be
shutdown according to the watchdog mode selected or will be
controlled using the preset setpoints. An operating system
crash, a PC power failure or a fault in the connecting cable to
the instrument can cause an interruption in data transmission.
"Watchdog"– Mode 1
If an interruption in data transmission occurs which is longer than
the preset watchdog time, the heating and shaking functions
will be shutdown and the error message PC 1 will be displayed.
"Watchdog"– Mode 2
If an interruption in data transmission occurs which is longer than
the preset watchdog time, the speed setpoint value will be set to
the WD safety speed setpoint and the temperature setpoint will
be set to the WD safety temperature setpoint.
The PC 2 warning message will be displayed.
