IKA LR 1000 control Package - Manual (Page 31)

The above details correspond as far as possible to the rec-
ommendations of the NAMUR working party (NAMUR rec-
ommendations for the design of electrical plug connections
for analogue and digital signal transmission on individual
items of laboratory control equipment, rev. 1.1). The NAMUR commands and the additional specific IKA ® co-
mmands serve only as low level commands for communication
between the machine and the PC. With a suitable terminal or
communications programme these commands can be trans-
mitted directly to the equipment. The IKA
® software pack-
age, labworldsoft ® , provides a convenient tool for controlling
device and collecting data under MS Windows, and includes
graphical entry features, for motor speed ramps for example.
NAMUR Commands Function
IN_NAME Input description name
IN_PV_X
X=1;2;3;4; Reading the real value
IN_SOFTWARE Input software ID number date, version
IN_SP_X
X=1;2;3;4;6; Reading the set rated value
IN_TYPE Input laboratory unit ID
OUT_NAME Output description name. (Max. 10 characters, default: LR 1000)
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
X=1;2;4;6 Setting the rated value to n
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.
START_X
X=1;2;4 Starting the instrument’s (remote) function
