Configuration
The LMS400 laser measurement sensor is adapted to the on-site measurement situation
by means of the configuration. You can configure and test the measurement properties, the
analysis behaviour and the output properties of the sensor as required.
Note
Along with the interactive configuration with the aid of SOPAS ET, you can also configure the
LMS400 using configuration messages.
On this subject please read section “Data communication using messages” in the chapter
“Product description” of the LMS400 operating instructions.
Save parameters permanently
The data are initially saved in RAM in the sensor so that you can check the effect
immediately. On completion of the configuration, you must save the parameters in the
EEPROM of the LMS400.
Don’t switch off the voltage supply during configuration!
ATTENTION
Switching off the voltage supply during configuration causes all parameters already
configured to be lost.
How to save the parameters permanently in the LMS400:
 From the LMS400-XX00 menu, choose the command PARAMETER, SAVE PERMANENT.
In this way the parameters are saved in the EEPROM in the LMS400 and will also be
available after the device is switched off and on again.
3.1
Preparing the configuration
To configure the LMS400 laser measurement sensor, you need:

SOPAS ET configuration software (not included in scope of delivery).
See Internet under: www.sick.com/sopas


LMS400 laser measurement sensor
 Connect the PC/notebook with the aux interface of the LMS400. The connection of the
PC is described in chapter “Electrical installation” in the LMS400 operating
instructions.
 Install the SOPAS ET configuration software.
Note
The second generation of SOPAS ET (version 2.38.3) can continue to be used, although
support for it is no longer being provided. To receive updates or support, please use the
latest version, i.e., the third generation of SOPAS ET (version 3.xx).
Download and installation of SOPAS ET
The configuration software SOPAS ET, the current system prerequisites for the PC, and the
instructions for downloading the software and the device description file(s) can be found in
the Web at: www.sick.com/sopas.
1. Start PC.
2. Download and install version V3.x of the SOPAS ET configuration software from the
online product page for the software by following the instructions provided there.
Administrator rights may be required on the PC to install the software.
3. Start the “SOPAS ET” program option after completing the installation.
Path: C:\Program Files (x86)\SICK\SOPAS ET\SopasET.exe or via Windows search.
4. Install the device driver (SDD) in the device catalog using the wizard (gear symbol). The
*.jar file can be obtained from the online repository if an Internet connection is present.
5. In the device search list, establish a connection between SOPAS ET and the LMS400
using the search settings. To do this, select the LMS4xx family of devices and select the
default IP address 192.168.0.1 when connecting for the first time. The device is
detected and can now be integrated into a project for configuration purposes.
Note

The installation file for SOPAS ET and the *.jar file for the device driver can also be
exported to a data card in order to install them on another PC when there is no Internet
connection.

The LMS4xx does not support Automatic Private IP Addressing (auto-IP). For this reason,
the device is not detected by the default search. To ensure the device search is
successful, the correct IP address and a sufficiently precise address range must be
specified. It is possible to save a search setting that has been set up specifically for this
purpose under a separate name (default: IP address = 192.168.0.1, subnet mask =
255.255.255.0).
3.2
Application
The LMS400 can be operated in two modes:

as a laser measurement sensor for the acquisition and output of pure measured data,
e.g. to a host

using the Level Control application for completeness and contents checks, e.g. on
containers

On this device page you can enter the coordinates and angle of the LMS400 over the
conveyor system and in this way define the zero point for the system.
You can also define the relevant working area as the measurement area.
3.3.1
Coordinates
As delivered the zero point for the distance measurement is at the origin of the laser
(marked by a dot on the top and underside of the housing).
The Level Control application requires a global zero point to which all other settings refer
(e.g. right edge of the conveyor system as seen in the transporting direction). You can define
this zero point with the aid of the X, Y and Z coordinates.
As a rule this zero point is at the bottom right edge of the conveyor system as seen in the
transporting direction.

Basic parameters
To be able to perform measurements with the LMS400, the basic parameters must be
configured. For this purpose configure the size of the scanning area, the angular resolution
and the scanning frequency in the scan settings.
3.4.1
Current device parameters
The CURRENT DEVICE PARAMETER area indicates the scanning frequency and the angular
resolution actually set and the resulting measured value quality.
Note
Values are only displayed if you configure a device online, that is the PC is connected to the
device.
Measured value quality
You cannot configure the measured value quality directly. The sensor calculates the
measured value quality based on the configured angular resolution and the scanning
frequency.
The measured value quality should ideally be 7. A higher value corresponds to a better
measured value quality. If the measured value quality determined from the parameters is
lower than 7, the sensor is no longer compliant with the values given in the technical data.

Advanced parameters
The advanced parameters are only available in the “Authorised client” user level.
Enable extended RIS detectivity
If you want to measure objects with remission values smaller or higher than the values given
in the data sheet for the LMS400, you can extend the so-called Remission-InformationSystem (RIS) in the LMS400. In this way the RIS facilitates, e.g., the improved detection of
dark or lighter bodies with reduced accuracy.
On this subject please read the section “Extended RIS detectivity” in the chapter “Product
description” of the LMS400 operating instructions .
For measured values that are measured using extended RIS detectivity the following
applies:

The distance value may not have the defined measuring accuracy.

The same measurement point/the same object will not necessarily be detected by
another LMS400 because the remission value determined is dependent on the factory
calibration of the sensor, outside the specified range the calibration may be subject to
minor variations.
With extended RIS detectivity, your application must therefore evaluate, based on
additional criteria, whether the distance value is to be used or not.

 Select there in the ADVANCED DEVICE PARAMETERS area the option DARK or LIGHT.
3.6
Filter
The LMS400 has digital filters for the pre-processing and optimisation of the measured
distance values.
Notes

You can combine the filters as required.

If several filters are active, then the filters act one after the other on the result of the
previous filter. The processing in this case follows the following sequence:
– edge filter
– median filter
– range filter
– mathematical filter

Active filter functions change the measured values that are output. It is not possible to
convert filtered output values back to the original measured values.
3.6.1
Contour filter
Edge filter
The edge filter prevents incorrect/extreme distance values at edges that result from it not
being possible to determine a distance value for the previous or next point (e.g. if the
previous/next measured point was too dark or outside the measuring range of 3 metres).
With the edge filter enabled, the LMS400 also sets a distance value to 0 at each edge.
On this subject please read the section “Edge filter” in the chapter “Product description” of
the LMS400 operating instructions.
Note
Using the edge filter, points can be completely suppressed at the outer edges of the object.
In this case the width determined for an object is too narrow by up to 2 × the angular
resolution.
How to activate the edge filter:
 Open in the PROJECT TREE, LMS400-XX00, PARAMETER the device page FILTER.
 Select there in the CONTOUR area the option ACTIVATE EDGE FILTER.

LMS400
Median filter
Note
The median filter is not available if on the APPLICATION device page the LEVEL CONTROL option
was selected (see 3.2 “Application” on page 8).
The median filter reduces individual extreme values over the entire measurement line by
outputting the median for each measurement point (not: the mean/average) from a 3 × 3
matrix. The matrix comprises nine measured values: The distance values for the point and
its neighbouring points, as well as the distance values determined for these points in the
previous and subsequent scan.
On this subject please read the section “Median filter” in the chapter “Product description”
of the LMS400 operating instructions.
How to activate the median filter:
 Open in the PROJECT TREE, LMS400-XX00, PARAMETER the device page FILTER.
 Select there in the CONTOUR area the option ACTIVATE MEDIAN FILTER.
3.6.2
Note
Range filter
The range filter is not available if on the APPLICATION device page the LEVEL CONTROL option
has been selected (see 3.2 “Application” on page 8).
The range filter reduces the number of valid measured values by only outputting distance
values that are within a specific distance range. For other measured values the filter
delivers the distance value 0 and the remission value 0 as the result.
How to activate the range filter:
 Open in the PROJECT TREE, LMS400-XX00, PARAMETER the device page FILTER.
 Select there in the RANGE area the option ACTIVATE RANGE FILTER.
 In the MIN. MEASUREMENT DISTANCE field enter a value of at least 700 mm and maximum
3000 mm.
 Then in the MAX. MEASUREMENT DISTANCE field enter a value larger than the value in the
MIN. MEASUREMENT DISTANCE field and maximum 3000 mm.
3.6.3
Mathematical filter
The mean filter smooths the distance value. For this purpose the filter forms the arithmetic
mean over several scans. The number of scans can be configured.
On this subject please read in the LMS400 operating instructions chapter “Product
description”, section “Mean filter”.
Recommendation
Use the mean filter together with the median filter. In this way individual outliers will be
smoothed in advance by the median filter.
How to activate the mean filter:
 Open in the PROJECT TREE, LMS400-XX00, PARAMETER the device page FILTER.
 Select there in the MATHEMATICAL area the option ACTIVATE MEAN FILTER.
 In the NUMBER OF AVERAGED SCANS field enter a value of at least 2 and maximum 100.

 Open in the PROJECT TREE, LMS400-XX00, PARAMETER the device page FILTER.
 Select there in the LEVEL CONTROL area the option ACTIVATE Z-MEDIAN FILTER.
Interval distance
At large column lengths and low conveyor speed a quantity of scans will be obtained that is
inappropriate for the evaluation of a column in the X direction. For this reason with the aid
of an interval you can define the magnitude of the distance between two scans that are to
be used for the measurement.
How to configure the interval distance:
 Open in the PROJECT TREE, LMS400-XX00, PARAMETER the device page FILTER.
 Enter there in the LEVEL CONTROL are in the INTERVAL DISTANCE field the necessary value
in mm.

Digital inputs/Trigger
Using the settings on the device page you can define whether the start and end of the
measurement are defined by triggers.
You can select whether the settings for the triggering are to be time or distance controlled.
You can define the sources for the triggering and if necessary the logic and debounce for
the digital inputs.
You can also define whether the laser in the LMS400 is switched on by a trigger or remains
switched on continuously.
3.7.1
Note
Operating principle of the LMS400
You can only change the settings if the Level Control application is activated (see 3.2 on
page 8).
The settings define what determines the start and end of the measurement.


Free running
In case of free running operating mode, measured value messages are output after the
LMS400 has received the measured value request until the output of measured values
is stopped by a stop message. Measurements are performed continuously or with
internal gate between the reception of the measured value request and the reception
of the stop message (see 3.7.7 on page 22).

Triggered (gate)
If you use an external gate, then the start and end of the gate (that is e.g. switching on
and off a photoelectric switch on a digital input) define the length of the columns.

 In the COMMON SETTINGS area select whether the measurement is to be triggered time or
track controlled.
3.7.3
Digital inputs
The digital inputs 1 and 3 (IN1 and IN3) are used for triggering the LMS400, for example
using external switches or sensors. To bridge bounce times on external switches, you can
configure an input delay for the inputs. For both inputs you can also select whether they are
to be active high or active low.
You will find the pin assignment for the inputs in the LMS400 operating instructions in the
chapter “Electrical installation”.
Note
Depending on whether the measurement is triggered time or track controlled (see 3.7.2
“Common settings” on page 19), you must enter the debounce for the inputs in ms or mm.
How to configure the settings for the digital inputs 1 and 3:
 Open in the PROJECT TREE, LMS400-XX00, PARAMETER the device page DIGITAL

Gate
The LMS400 provides several trigger sources for gate control. These can start or stop the
measurement immediately or initiate a delayed start and/or stop of the measurement.
On this subject please read section “Control of the measurement process using a gate” in
the chapter “Product description” of the LMS400 operating instructions.
SOPAS ET provides several trigger sources for gate control:

digital inputs

software trigger

CAN BUS

test trigger (see 3.7.6 “Advanced I/O settings” on page 22)

triggering by the LMS400 master
The trigger sources can stop or start the measurement immediately, or trigger a delayed
measurement start and/or stop.
In addition, you can extend the gate produced by the triggering with a so-called expansion
distance.
Note
Depending on whether the measurement is triggered time or track controlled (see 3.7.2
“Common settings” on page 19), you can enter the delay and expansion as a distance or as
a time.
Example:
A photoelectric switch is mounted 1000 mm in front of the scan line. You initialise the start
of the measurement on the entry of the object into the photoelectric switch. You initialise
the measurement when the object leaves the photoelectric switch.
1000 mm are entered as the distance delay. In this way the measurement is actually only
started when the object reaches the scan line, and only stops when it leaves the scan line.
If an expansion distance of 50 mm is now entered, the measurement starts 50 mm before
the object reaches the scan line and stops 50 mm after it leaves the scan line.
You can start and stop the measurement using one trigger source or you can use one trigger
source to start and a second to stop the measurement.
How to configure a gate:
 Open in the PROJECT TREE, LMS400-XX00, PARAMETER the device page DIGITAL
INPUTS/TRIGGER.
 In the GATE SETTINGS area in the START TRIGGER SOURCE and STOP TRIGGER SOURCE selection
field select the source for the triggering.
 Configure as necessary DISTANCE DELAY and EXPANSION DISTANCE.
Gate for the Level Control application
In the Level Control application the start and stop of the gate (that is e.g. switching on and
off a photoelectric switch) define the length of the columns or the length over which
columns are generated (see 3.7.7 on page 22).
On this subject please read the section “Evaluation in X direction” in the chapter “Level
Control” of the LMS400 operating instructions.

Laser control
With laser control active, the switching on of the laser is controlled by the gate configured
or by a dedicated source.
On this subject please read the section “Laser control” in the chapter “Product description”
of the LMS400 operating instructions.

GATE CONTROLLED
The laser is controlled by start and stop trigger source configured in the Gate settings
area (see 3.7.4 “Gate” on page 20).

DEPENDENT ON SOURCE
The laser is controlled by the source configured in the SOURCE selection field. The control
is independent of the settings made in the GATE SETTINGS area.
Control of the laser by a dedicated source
As soon as the LMS400 has calculated, based on encoder pulses (see 3.8.2 “Increment
configuration” on page 23) that a certain distance (the laser off distance) has been
reached, it switches off the laser. In addition, a laser timeout ensures that after a certain
amount of time, the laser is switched off in all circumstances.
If, between switching on and off the laser, the start trigger is set again (for instance by a new
object passing a photoelectric switch), the distance calculation and the laser switch off
delay counter are set to zero and re-started. The laser therefore remains switched on.
How to configure the laser control:
 Open in the PROJECT TREE, LMS400-XX00, PARAMETER the device page DIGITAL
INPUTS/TRIGGER, area LASER CONTROL.
 In the LASER CONTROL area select the GATE CONTROLLED or INDEPENDENT option.
 In the case of independent laser control, in the SOURCE selection field select the DIGITAL
INPUT IN1 or DIGITAL INPUT IN3 option if the laser is to be triggered by switches or sensors
that are connected to inputs. Select the SOFTWARE TRIGGER option if the laser is to be
triggered using a message over one the interfaces.
 In the LASER TIMEOUT field enter the time in minutes after which the laser is to be
switched off.
 In the LASER OFF DISTANCE field enter the distance after which the laser is to be switched
off.
Note
8011984/YSZ3/2016-02-04
The LMS400 can count a maximum of 30000 encoder pulses from the time the trigger
is activated until the lasers are switched off. With the encoder resolution of 0.2
mm/incr. of the recommended encoder this results in 30000 × 0.2 mm = 6000 mm.

The INTERNAL GATE device page is only displayed if you have activated the application Level
Control (see 3.2 on page 8).
If you use an internal gate, the GATE ON parameter defines the length of the columns and the
GATE OFF parameter defines the gap between two columns.
The columns can be “generated” continuously by the internal gate or instead limited by an
external gate (see 3.7.4 on page 20).
If you use an external gate, the start and end of the gate define the start and end of column
generation. Between start and end the internal gate defines the length of the columns.

Encoder and synchronization
3.8.1
Master/slave configuration (synchronization)
If you use two LMS400 as master and slave over the “System” connection, then you must
configure one device as master and the other one as slave.
Notes

On master/slave operation, master and slave must be configured to the same scanning
frequency and angular resolution (see “Scan settings” on page 14).

Once the mirrors have run up, master and slave must synchronise with each other. This
can take up to 120 seconds. Note that until synchronisation is complete, the measured
values supplied by the two devices are not synchronised.
Phase
On the use of two LMS400 in a master/slave system it may occur that one LMS400 received
the beams from the other LMS400 and is affected by the beams.

Use the graphic scan view in SOPAS ET to verify the measured values generated and to
verify the measurement area online.
Notes

The scan view in the monitor is dependent on the available computing power of the
connected PC and is not output in real-time. For this reason not all measured values are
displayed. The same limitation also applies when saving measured values displayed in
a file.

The monitor displays the measured values unfiltered, i.e. the action of filters can not
be checked with the aid of the monitor.
In the scan view you have the following additional options:

You can display distance values, energy values or distance and energy values.

You can change the diagram display.

You can save the scan data to a file.

Glossary
Download
Transmission of the parameter set that has been modified offline in the SOPAS ET
configuration software from the PC to the LMS400. SOPAS ET transmits either always a
complete copy to the memory (RAM) of the LMS400 (menu COMMUNICATION, DOWNLOAD ALL
PARAMETERS TO DEVICE) or only the parameter that has just been edited with the aid of the
context menu of the right mouse button (menu COMMUNICATION, DOWNLOAD MODIFIED
PARAMETERS TO DEVICE). With menu LMS400, PARAMETER, SAVE PERMANENT, the parameter set
is saved permanently in the EEPROM of the LMS400.
Field of view 
Angle that defines the limits to which the read beam is deflected by the polygon mirror
wheel. A v-shaped area is formed radially in the scan direction in front of the laser output
opening; this area must contain the objects to be measured.
Host interface
Primary data interface for the LMS400 with configurable measured data output format. Is
used, among other tasks, for the output of the measuring result in message format to the
host/the PLC. Used to integrate the LMS400 in the SICK network. Can be connected
electrically as RS­232 or RS­422. Provides various transmission protocols.
Line scanner
Scanner that very rapidly deflects its focused laser beam with the aid of a polygon mirror
wheel with mirrors parallel to the axis. In this way the scanner generates a dot of light in the
measuring plane that repeatedly runs along a straight line and appears to be a “stationary”
scan line due to the relative slow response of the human eye.
Parameter set
Data set using which the functions implemented in the LMS400 are initialised and
activated. Is transmitted from the LMS400 to SOPAS ET and in the reverse direction using
UPLOAD or DOWNLOAD respectively.
Remission
Remission is the quality of reflection at a surface. The basis is the Kodak standard, known
worldwide in, among other areas, photography.
RIS
Remission Information System: The RIS value corresponds to the remission value without
application of the scaling factor. It states the reflectivity of the object in percent determined
by the system. A small RIS value signifies a low reflectivity (as a rule a dark object). Only
distance values with RIS values  5 (= 10%) are inside the specified range of the LMS400.
With RIS values < 5 the reliability of the measured result is low.
Scan
A scan encompasses all measured values determined referred to the scanning angle and
the speed of rotation of the mirror.

Aux interface
Auxiliary data interface (RS­232) on the LMS400 with fixed measured data output format.
Using this interface it is always possible to access the LMS400 using the SOPAS ET
configuration software. Is used, among other tasks, for the output of system messages and
error messages. Can be used with various functions.
