3 General information on LMS2xx and LMI400
LMS2xx (laser measurement systems) can be configured for stand-alone operation or for
operation with the LMI400 (interface) with the LMSIBS Configuration Software.
One distinguishes between two different scanners:
LMS2xx with 10 mm resolution
and
LMS2xx with 50 mm resolution
LMS2xx units with 10 mm resolution offer programmable monitored zones with
corresponding switching outputs in stand-alone operation, i.e. without external evaluation.
The functions and options required can be configured within the scanner itself.
In the case of LMS2xx units with 50 mm resolution, the monitored fields and
corresponding switching outputs are only available through the LMI400. A system
diagnosis can, however, be carried out with the Configuration Software.

Communication Assistant
7 Communication Assistant
If no LMS2xx/LMI400 has been connected to the PC
when the program is started, or the wrong interface has
been selected, the opposite window appears.
The Communication Assistant will help to define the
correct PC data interface.
Select the LMS2xx type or LMI400.
Please note:
LMS2xx units with 50 mm resolution (types 1 ... 5) allow a
system diagnosis to be run, while monitored fields can only
be set-up with the LMI400.
The program attempts to find the LMS2xx/LMI400 at all
the serial interfaces (COM 1, COM 2, ...) available on the
PC, using a variety of transfer rates (baud rates).
The Status Bar on the PC monitor shows the current
situation.
This window appears after successfully
finding the LMS2xx/LMI400.
If the search has been unsuccessful, check that the
LMS2xx/LMI400 is correctly wired up and switched on
(see the Technical Descriptions for further information on
electrical connecting).

8009116/V4.1/2002-07
Chapter 9
The selected settings can be checked again in
page view.
The Configuration Software now suggests the
transfer of the settings to the LMS2xx:
Log in the authorised user group.
Password: SICK_LMS
Please note:
Only authorised users are permitted to transfer
configurations.
"Machine operator" status only allows reading.
The password can be changed at any time.
The basic settings of the LMS2xx are permanently saved in the LMS2xx after transfer.
The LMS2xx is switched to Monitoring Mode by pressing the "F3" key on the PC (or
selecting the function via the Menu Bar). The PC can remain attached for observation or
be removed at any time.
The LMS2xx automatically goes into Monitoring Mode when it is cold-started (power is
switched on).

Chapter 10
9.2 Preparation for field evaluation
1. Select:
LMS – Select function – Field configuration
from the Menu Bar.
(Menu selection is also available using the right mouse button)
2. A total of 2 field sets can be used.
The field types for both LMS2xx field sets are to be selected
here (fields A, B, C separately for each).
Please note:
The choice of segmented or rectangular can be changed again
later.
(see also Section "Converting fields", page 27)
3. This is where use of the optional restart input is defined. On
selecting Change field set one can change from one field set
to the other (only one field set is ever active at one time).
In addition, a time element for delayed restart after release
can be activated for the various fields.
The synchronisation of two LMS2xx (Master-Slave) is rarely
used in field applications (see Section "9.4 Synchronisation of
two LMS2xx units", page 22, for more details).
16
8009116/V4.1/2002-07
Chapter 9
4. The number of multiple readings is now defined in the
window opposite.
Higher values improve the filtering out of snow, rain, or
particles, though response times increase with the setting.
A blanking factor can also be entered (only in conjunction
with scan-oriented evaluation, however). This determines
the object size that the switching outputs will respond to.
Subtractive evaluation
Definition of whether evaluation is to be carried out
subtractively is made in the window shown opposite, i.e.
field B is subtracted from field A. The remaining area is then
treated as the monitored area (signalling at output Out A).
Use motor flap (only for LMS210/211):
An optional motor flap (a shutter) is available for the front
window of the LMS210/211. It is used wherever the
scanner is to carry out temporary monitoring tasks, to
improve the availability of the LMS210/211 (protecting it
against pollution, sabotage, etc.).
This function need only be activated for stand-alone
LMS210/211 units when the flap is contacted via external
data telegrams. Then the LMS210/211 unit's 24 V
switching output Out A is automatically used for shutter
movements. Out A is, of course, no longer available as a
signal output for monitored fields.
Alternatively, the flap can be moved via an external 24 V DC
control voltage. In this case the function must not be
activated and Out A continues to be available as a signal
output for monitored fields (see LMS2xx Technical
Description for further details).
5. The system now suggests accepting the configuration
and transferring the settings to the LMS2xx. All the settings
so far made can be checked again on the page view that
then follows.
If Edit fields straight away is selected the system switches
to field editing mode after transfer. The fields can then be
edited immediately, either graphically or numerically.

9.3 Editing/changing LMS2xx configuration
1. Select:
LMS – Configuration – Edit
from the Menu Bar to edit the LMS2xx configuration.
2. Six register cards appear in the window that opens.
Sensor:
The sensor type (scanning angle, angular resolution, units of
measurement) can be changed here.
Selectable "data flags" are available in a data string for
further processing of LMS2xx raw data. Their significance
can be selected here (see chapter on "12.
LMS2xx/LMI400 Measurement technique”, page 58, for
more information).
The flags are not necessary for field applications in standalone operation.
18
8009116/V4.1/2002-07
Chapter 9
Fields:
Every partial field (A, B, C) can be edited (Edit...) directly
here (see also Section 11.5 "Editing fields", page 46, for
more information).
In addition, a field can be laid down in the volatile memory.
This allows fields (A, B, C) to be changed online during
operation by externally supplied information. This function
can, for example, be used for AGVs for negotiating curves
or avoiding obstacles (see LMS2xx/LMI400 Telegram
Listing for more information).
Please note:
After switching off power supply the field information in the
volatile memory is lost and must be re-entered after the
system has been restarted.
Restart:
The parameters for
- restart input
- restart delay
can be changed or checked here.
8009116/V4.1/2006-07

Chapter 10
Contour as reference
Select:
from the Menu Bar.
Select the "Contour" register card.
Activate the function for the desired fields and select
Settings...
Please note:
The reference contour function is always linked to a
monitored field. If no field has been programmed the
system automatically creates a field within the selected
validity range.
The individual parameters are entered here (see also
Chapter "15. Glossary, page 73").
The contour loss [cm] entry determines the size up to which
contour infringements are to be suppressed (e.g. objects
that block the LMS2xx unit's view of the contour).
The pos./neg. tolerance entry determines the tolerance
corridor within LMS2xx measured values may be made
(measurement of distance to contour).
The position (validity range) of the reference contour within
the LMS2xx unit's scanning range is entered using angular
values (from x to y ).
Please note:
The start and stop angle for the position can be read off
directly using the mouse pointer and automatically entered:
Click with the mouse's pointer on one of the two symbols
next to the angular value entered (see arrows opposite).
The mouse pointer is then moved to the desired position in
the scanning range and a single click at the desired position
marks the angular value and enters it automatically in the
edit window.
20
8009116/V4.1/2002-07
Chapter 9
After entering the parameters please select Actualise.
The defined monitored field is displayed with the contour
area below the editing window. The tolerance corridor you
set is also visible after actualisation (pos. / neg. tolerance).
The field limit of the corresponding monitored field has now
been shifted within the validity range up to the contour itself
(zero point for the tolerance corridor).
Evaluation:
The parameters for:
- multiple evaluation,
- blanking,
- subtractive evaluation, and
- use of the motor flap,
can be changed or checked again in the window shown
opposite.
Blanking:
Select the option Scan-oriented under the blanking
function. You can now enter the blanking factor directly as
an amount in "cm" (object size for objects that are not to
be detected).
Evaluation of suppressed objects:
Objects that are smaller than the blanking factor entered
above can cause a shadow to be thrown in the sensor field
without being noticed (e.g. as an attempt at sabotage). A
supplementary evaluation can be implemented so that such
objects can nonetheless be detected: all detected objects
below the entered threshold are evaluated via a separately
adjustable reading cycle and their continuing existence is
reported.
In the window opposite you can enter the number of
reading cycles for this purpose.
Please note:
The number of reading cycles must always be higher than
the value entered under multiple evaluation.

Chapter 10
9.4 Synchronisation of two LMS2xx units
If two LMS2xx units are operated in close vicinity to each other, e.g. for measuring
packages, there may be mutual interference under certain circumstances. In order to
prevent this the rotating mirrors of the two LMS2xx units can be synchronised. The mirrors
are then maintained in a position displaced by 180 relative to each other.
In the process one LMS2xx is defined as the master, the other the slave.
LMS2xx units from software version 02.02 upwards and hardware above serial number
9919... are capable of synchronisation.
(See the LMS2xx Technical Description for more information on the wiring necessary).
Defining the LMS2xx as master:
1. Select:
from the Menu Bar.
2. Select the Restart register card
3. Activate the master function control box.
22
8009116/V4.1/2002-07
Chapter 9
Defining an LMS2xx as slave:
1. Select:
from the Menu Bar.
2. Select the Restart register card
3. Activate the restart input for slave function.
Extras:
Sensitivity may only be changed in exceptional
circumstances (see the LMS2xx Technical Description for
sensitivities/response behaviour).
The "High sensitivity" setting improves the detection of
black but also raises the sensitivity towards ambient light
and interference caused by environmental factors
(particles, etc.).
The "Low sensitivity" setting improves immunity to ambient
light but simultaneously reduces detection reliability for dark
objects.
4. The configuration must be transferred to the LMS2xx
again after editing:
Press the "F9" key (see page 15)
The page view displayed shows the corresponding settings.

9.5 Adjusting fields
1. Select:
LMS – Monitored field – Graphical edit
or
LMS – Monitored field – Numerical edit
from the Menu Bar.
Graphical editing is recommended.
After selection (graphic) a cross is visible above the mouse
pointer.
Please note:
Fields can also be automatically taught-in (see Section
"Teaching-in fields", page 26).
2. The field to be edited is selected from the pull- down
menu in the window shown opposite.
The LMS2xx scanning line is displayed for orientation (if
"Active sensor" is selected).
3. Monitored fields can be programmed within the scanning
range of the LMS2xx.
The appropriate field points are set (marked yellow) by
double-clicking in the desired position.
A single click on an existing field point selects the point.
Selected points can be deleted or moved. A cross on the
yellow square signifies selection.
4. The window opposite appears after all the desired fields
have been edited and the "Edit monitored fields" mode has
been left.
The Configuration Software now suggests transferring the
entire configuration.
Please note:
Only authorised customers can transfer configurations.
24
8009116/V4.1/2002-07
Chapter 9
5. The page view opposite appears before the
configuration is sent to the LMS2xx. It is again possible to
check the programmed fields and all the settings that have
been made.
Transfer can be stopped at this point so that the
configuration can be changed again.
6. The LMS2xx can be switched into "Monitor Mode" after
transfer. The "F3" key is used for this, or the Taskbar icon
below the Menu Bar can be activated.
The PC can remain connected for observation or be
unplugged from the LMS2xx at any time.
The LMS2xx automatically adopts Monitor Mode after a
cold-start (switching power supply on).
8009116/V4.1/2006-07
25
Chapter 10
Teaching-in fields
Fields can be automatically "learnt" using the teach-in method. The entire field of view of
the LMS2xx is defined as a field size. The teach-in function allows precisely positioned
fields to be set up, particularly where field limits are to end just before a solid immobile
object (e.g. a wall).
Please note: only segmented fields can be taught-in.
1. The fields to be "learnt" is selected from the pull-down
menu of the window shown opposite.
2. Select:
LMS – Monitored field – Teach-in
or
press the "F5" key on the PC
or
click on the icon in the Toolbar
3. The taught-in monitored field is displayed on the screen
during the teach-in process. Teach-in is completed by
pressing the F5 key.
The system adjusts the field in such a way that a tolerance
corridor is left between the field limit and the object contour
(surroundings). This corridor is:
• 70 mm for LMS2xx with 10 mm resolution or
• 130 mm for LMS2xx with 50 mm resolution
26

Converting fields
The selected field settings rectangular or segmented can be changed using the converter
function. Thus, for example, what was originally a rectangular field can be converted to a
segmented field, and vice versa, if it becomes apparent during programming that a
different field shape would be desirable.
Example: segmented to rectangular:
1. Select:
LMS – Monitored field –
Convert to – Rectangle
2. The system now suggests a size for the rectangular field.
The values can be changed as required.
3. After making the appropriate entries the converted
rectangular field appears on the screen.
4. The configuration must be transferred to the LMS2xx

LMI400 interface
Chapter 10
10 LMI400 interface
10.1 Evaluation principle
The LMI400 receives raw data from the LMS2xx connected. The LMS2xx units provide the
maximum values for their field of view.
All the monitored fields are laid down in the LMI400 and linked to the LMS2xx according to
their settings. The fields, adjusted as required, can be linked to any of the LMS2xx units
connected.
The linkage of the fields with the LMS2xx and the switching outputs is carried out in socalled evaluation cases.
The conditions under which it is to be active can be defined for each evaluation case. The
individual evaluation cases are contacted or activated via the static 24 V DC control inputs
(A, B, C, D).
The LMI400 fundamentally operates using double or triple fields (see diagram below). A
field set's component fields A, B, or A, B, C can be defined independently of one another,
though a field set can only be linked to an LMS2xx as a complete entity. It is, however,
irrelevant whether all component fields are used.
When a field set has been allocated an output, then component field A is firmly assigned
to switching output 1A or 2A, component field B to output 1B or 2B, field C to output 1C or
2C. Output 2C can be used for field evaluation or for reporting pollution.

This window appears. The 4 register cards are intended for
use with the standard application.
Linkages:
Each of the components in blue are linked to the current
evaluation case.
One sensor and one field set are available in the standard
application.
I/O definitions:
The input conditions (control inputs A, B, C, D) under which
the evaluation case is to be active are now defined here:
X – any state (always active)
0 – low (0 V)
1 – high (+24 V DC)
The output group to be activated in the case of a field
infringement is also defined here.
Evaluation:
Multiple evaluation:
Higher values improve the filtering out of snow, rain or
particles, though response times are also increased
proportionately.
Blanking:
Only in conjunction with scan-oriented evaluation.
Determines what object sizes are not to be reported.
Select Scan-oriented.
Enter the blanking factor in "cm" (object size that is not to
be detected).
Evaluation of suppressed objects:
Objects that are smaller than the blanking factor entered
above can throw a shadow into the sensor field without
being noticed (e.g. as a sabotage attempt).
A supplementary evaluation can be implemented in order to
8009116/V4.1/2006-07
33
Chapter 11
nonetheless be able to detect such objects:
all detected objects below the entered blanking threshold
are evaluated in separately definable reading cycles and
their continued existence is reported.
You can enter the number of reading cycles for this type of
evaluation in the window shown opposite.
Please note:
The number of reading cycles must be greater than the
value entered under multiple evaluation (recommendation:
2 x multiple evaluation).
Subtractive evaluation:
This defines whether the evaluation is to operate
subtractively or not, i.e. whether field B is subtracted from
field A. The remaining area is then the valid monitored area
(signalling at output Out A of the selected output group).
Use motor flap (only LMS210/211):
A motor flap (shutter) is optionally available for the front
window of the LMS210/211. It is used for increasing
LMS210/211 availability where the scanner has temporary
monitoring tasks, protecting it against pollution, sabotage,
etc.
If the function is activated the motor flap opens on selection
of the relevant evaluation case and the LMS210/211 is
ready for scanning. On changing the evaluation case
(control inputs) the flap closes automatically.
Alternatively the LMS210/211 flap can be moved directly
via an external 24 V DC control voltage (see LMS2xx
Technical Description for electrical connection). In this case
the function should not be activated.
Restart:
The component fields A, B, C can be programmed with
different restart characteristics after a field infringement has
occurred.
The parameter can be entered after selecting the Setup...
button for the particular field. For restart with delay the unit
used may be selected as seconds or 1/10 second.
3. On confirming with OK all parameters for the standard
application have now been defined.

Logging communication
This function can be used to check data or telegram traffic between the LMS2xx/LMI400
and PC.
After selection of the desired function, use of the "Change operating mode" button (see
dialog box below) results in the appropriate telegram being sent to the sensor.
Order of input (in the case of LMI400 applications select active sensor first):
- select Function,
- use the "Change operating mode" button,
- use the "Join" (connect) button.
- The output process is ended by using the "Stop" button.
1. Select:
Measurement technique – Log communication
from the Menu Bar.
The dialog box opposite appears.
2. The partial section or number of averagings to be read
(depending on the function selected) can be entered. All
replies from the sensor (measured values) can be saved
after display (log file "*.log").
Display of the measured values can be Cartesian or polar
(x/y values or radius/angle).
Minimum radial measured value on field infringement:
The sensor only supplies measured values after a field
infringement.
All measured values continuously:
The sensor provides a constant supply of measured values.
Minimum measured values continuously:
The sensor provides a constant supply of the shortest
measured distances (per field segment).
Continuous perpendicular distance:
Only in conjunction with a rectangular field. The sensor only
provides the smallest perpendicular distance to the object
in the corridor or the field's transient direction (also values
outside the field, no field infringement necessary).
Continuous averaged measured values:
Output of all measured values. An average value of the
individual measured values can be formed to smooth out
the values.
Continuous partition of measured values:
Constant output of all the measured values within the
defined field section.
Continuous partition of measured values and field values:
As above, but with the additional output of the distance to

the outer field limit. I.e. information is provided on the radial
distance to the LMS2xx for a measurement beam that
leaves the particular field (separate for fields A, B, C).
Continuous averaged partition of measured values:
Constant output of all measured values of a partial section
with average value formation for smoothing.
All measured values direct continuously:
Constant output of all raw measurement values.
Continuous measured values and reflectivity values:
Output of all measured values and their corresponding
object reflectivity values.

Glossary

15 Glossary
Blanking
Contour as reference
A so-called blanking factor is defined in "cm". The blanking factor defines the minimum
object size that leads to a message at the switching outputs.
Please note: blanking is only possible in conjunction with scan-oriented evaluation (not in
conjunction with pixel-oriented evaluation – see below).
This function additionally monitors the surroundings of a monitored field (background), i.e.
an object (e.g. a house wall) is constantly checked for its continued existence. If this
contour is missing the corresponding switching output is activated, even without a field
infringement. The validity range of the reference contour can be defined as required:
The minimum object size defines how many cm of a reference contour may be "missing"
before a switching signal is triggered.
The pos./neg. tolerance allows a corridor for LMS2xx measured values to take up their
tolerances or balance fluctuations in the contour (pos. = tolerance band for larger
measurement values = measurement of the contour's larger distance; neg. = tolerance
band for smaller measured values = measurement of the contour's smaller distance).
Measured values outside the corridor are evaluated as loss of contour.
This function can also be employed to prevent sabotage. Basically, the standard field
evaluation is valid outside the defined corridor.
Customer, authorised
All configuration settings can be transferred to the LMS2xx/LMI400 with authorised
customer status.
Customer, machine operator All settings can be checked but not changed or transferred with machine operator status.
Field evaluation
To prevent erroneous switching through particles, etc. fields are evaluated using different
processes (scan-oriented or pixel-oriented – see below).
Field evaluation,
pixel-oriented
With pixel-oriented field evaluation every single scanner beam is evaluated and stored
temporarily – unlike the scan-oriented process. The corresponding switching signal is
triggered if infringements are repeated sequentially at the same beam (pixel). This
method is best suited for increasing availability in rain and snow.
Field evaluation,
scan-oriented
With scan-oriented field evaluation a field infringement at a particular location is saved
and verified using multiple reading. If further infringements are reported in subsequent
scans (at the particular location) then, depending on the number of multiple readings
defined, the field's corresponding switching output is activated.
Field infringement
The detection of an object within a pre-defined monitored field.
Field set switching
Changing between different field sets. In the LMS2xx either field set 1 or 2 is active, in the
LMI400 2 field sets can be activated simultaneously. The change of field set in the
LMS2xx takes place via the restart input (24 V DC static), in the LMI400 through separate
control inputs (24 V DC static).
Alternatively, field sets can also be switched via software telegram.
Field sets
Consist of 2 or 3 individual monitored fields:
(fields A, B or fields A, B, C).
2 field sets can be saved in the LMS2xx, and up to 4 in the LMI400.
Field, dynamic
Only for LMI400; field shapes and sizes can be changed automatically dependant on
shaft encoder input (e.g. speed for an AGV application).
Field, volatile
A field form can be defined and activated by external data information online via the user
interface, transfer time approx. 200 ms (volatile [temporary] as the field is lost when
power supply turned off).
Fields, subtractive
Allows a zone to be monitored that is the "remainder" of field A minus field B.
8009116/V4.1/2006-07

Chapter 15
Glossary
Fields, teach-in
Fields can be taught-in, when set to "segmented fields" instead of their being
programmed. The LMS2xx or LMI400 defines the entire free scanner field of view as the
monitored area. This function is extremely helpful for large fields, e.g. securing building
facades. The field limits precisely follow the contour of the surroundings and ensure the
largest possible cover. Field sections that are not required (e.g. the outermost edges),
can be deleted (cut out) in the Configuration Software in a few easy steps.
Monitored fields
Freely programmable zones (areas); objects that are detected in a field by an LMS2xx
trigger a switching signal.
Reflectivity (remission)
Reflectivity is the amount of reflection from a surface.
The well-known photographic KODAK standard, among others, forms the basis for
reflectivity measurements (see also Technical Description).
Resolution
The resolution of a LMS2xx shows how precisely distance values are determined and
given out. For pulse time-of-flight measurements this is basically dependent on the
counter resolution (stop watch).
Restart,
with delay
The corresponding switching output is active only after the defined delay has elapsed (if
the field is free).
Restart,
with button
The corresponding switching output is active only after the external button has been
pressed (if the field is free).
Restart, automatic
The corresponding switching output is active immediately after the field is released as
free.
Synchronisation
If LMS2xx are employed in close proximity to one another (< 6 m), under certain
unfavourable conditions scanners may cause mutual interference. Synchronisation
ensures that the mirror wheels of the two LMS2xx units correspond to one another. The
mirrors then rotate synchronously displaced by 180 . The LMSIBS Configuration Software
is used to define 1 LMS2xx as a master and the other as a slave (see Technical
Description for cable connections).
