IN_NAME
Title request
IN_PV_X
X=1;2;3;4;;
Current value reading
IN_SOFTWARE
Software ID number, date, version request
IN_SP_X
X=1;2;3;4;12;42
52;54;
Set target value reading
IN_TYPE
Lab device identification request
OUT_NAME name
Output of identification name. (Max. 6 characters; default: IKAHBR)
OUT_SP_12@n
Setting WD safety limit temperature with set value echo
OUT_SP_42@n
Setting WD safety limit speed with set value echo
OUT_SP_X n
X=1;2;4;52; 54;
Setting of target value to n
OUT_WD1@m
Watchdog mode 1: if event WD1 should occur, the heating and stirring func-
tions are switched off and Er2 is displayed. Set watchdog time to m (20 -
1,500) seconds, with watchdog time echo. This command launches the
watchdog function and must be transmitted within the set watchdog time.
OUT_WD2@m
Watchdog mode 2: if event WD2 should occur, 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 dis-
played. The WD2 event can be reset with OUT_WD2@0 - this also stops
the watchdog function. Set watchdog time to m (20 - 1,500) seconds, with
watchdog time echo. This command launches the watchdog function and
must be transmitted within the set watchdog time.
RESET
Switches off the device function.
RMP_CONT_X
X=1;4
Continuaton of ramp function (After prior RMP_PAUSE_X).
RMP_IN_X
X=1;4
Reading the real segment number of ramp. With ramp not started: 0
RMP_IN_X_y
X=1;4
Reading the accumulated value and the ramp segment duration of ramp seg-
ment y.
RMP_LOOP_SET_X
X=1;4
Ending of ramp loop.
RMP_LOOP_RESET_X X=1;4
To work off the ramps in one loop.
RMP_OUT_X_y n
hh:mm:ss
X=1;4
Setting the accumulated value (n) and the ramp segment duration (hh:mm:ss)
for ramp segment y.
RMP_PAUSE_X
X=1;4
Stopping the ramp function. Freezing of real rated value and real ramp seg-
ment time.
RMP_RESET_X
Switching off ramp functions and deleting of all set ramp segments
RMP_START_X
X=1;4
Starting the ramp function, beginning with ramp function No.1 (Only possible
after prior START_X. After RMP_STOP_X START_X is not necessary.)
RMP_STOP_X
X=1;4
Switching off ramp function. Rated value = 0. (Ramp is maintained, that
means, ramp can be restarted with RMP_STARTX_X).
START_X
X=1;2;4;5;7
Starting the instrument’s (remote) function.
Remote
PC 2.1 cable
The PC 2.1 cable is used to connect the 9-pin plug to a computer.

STOP_X
X=1;2;4;5;7
Switching off of device - (remote) function The variables set with OUT_SP_X
remain saved. Includes command RMP_STOP.
Remote
“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 cable between the computer and the device.
“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 Er2 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.
