• Each individual instruction including parameters and data as well as each reply
are terminated with CR LF (Code: hex 0x0D and 0x0A) and have a maximum
lenght of 80 characters.
• The decimal separator in a floating point number is the point. (Code: hex 0x2E)
The above statements largely correspond with the recommendations of the
NAMUR-Assocation (NAMUR-recommendations for the design of electric plug
connections for the analog and digital signal transmission to labortory - MSR
individual units. Rev. 1.1).
Overview of the NAMUR-instructions
Abbreviations:
X,y = numbering parameter (integer number)
m = variable value, integer
n = value of variable, floating point number
X = 1 Pt1000 medium temperature (external temperaturesensor)
X = 2 temperature (incubations room)
X = 3 safety temperature
X = 4 speed
X = 6 safety speed
X = 50 Pt1000.60 medium temperature sensor offset in K
(-5.0 <= n <=+5.0)
X = 52 incubations room temperature sensor offset in K
(-5.0 <= n <=+5.0)
NAMUR instuctions Function

IN_TYPE Input laboratory unit ID
NAMUR instuctions Function
OUT_NAME name Output description name. (Max. 10 characters,
default: KS4000 ic)
OUT_SP_12@n Setting the WD safety temperature with the
echo of the set value
OUT_SP_42@n Setting the 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 occurs,
the heating and shaking functions are shutdown
and message PC 1 is displayed.
Set the watchdog time to m (20...1500)
seconds, with echo of the watchdog time. This
instruction starts the watchdog function and
must be sent within the set watchdog time.
OUT_WD2@m Watchdog mode 2: When a WD2 event occurs,
the speed setpoint will be set to the WD safety
setpoint speed and the temperature 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 watchdog 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
