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.

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!

Switching off the voltage supply during configuration causes all parameters already configured to be lost.

Chapter 3

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

 PC/notebook (Windows 98, NT 4.0, 2000, XP, Vista, 7, 8 or 10) with Ethernet interface

(RJ45) and optional serial interface (RS232). Device not included in scope of delivery.

 Optional for configuration via serial interface (RS232): a threecore RS232 connection

cable (null modem cable) for connecting PC and LMS400. Cable not included in scope of delivery.

How to prepare the configuration:

 Ensure that the LMS400 laser measurement sensor has been correctly assembled and

that the electrical connections are also correct.

 Plan all required settings (operating modes, beam coding, resolution, measured value

filtering, trigger etc.).

3.3 Position

Note The POSITION device page is only displayed if you have activated the Level Control application

(see 3.2 on page 8).

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.

3.4 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 C

URRENT 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.

3.5 Advanced parameters

Note 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.

8011984/YSZ3/2016-02-04

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.

How to activate the extended RIS detectivity:

 Open in the PROJECT TREE, LMS400-XX00, PARAMETER, BASIC PARAMETER the device page

DVANCED PARAMETERS.

 Select there in the A

DVANCED 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.

Online help

LMS400 laser measurement sensor

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 C

Median filter

Note The median filter is not available if on the A

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.

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.

3.7 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 Operating principle of the LMS400

Note 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.

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”.

3.7.4 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

NPUTS/TRIGGER.

 In the G

ATE 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).

3.7.5 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.

 G

ATE 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).

 D

EPENDENT 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 G

ATE 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

NPUTS/TRIGGER, area LASER CONTROL.

 In the L

 In the case of independent laser control, in the S

 In the L

ASER TIMEOUT field enter the time in minutes after which the laser is to be

switched off.

 In the L

ASER OFF DISTANCE field enter the distance after which the laser is to be switched

off.

Note 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.

3.8 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 tak e up to 120 se conds. Not e 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.

Chapter 3

To significantly reduce the probability of mutual interference, the two LMS400 can synchronise with each other so that their rotating mirrors rotate offset from each other by a specific angle. This angle is termed the “Phase”.

Recommendation On the master set a phase of 35°. Then the mirrors will rotate offset by one half field of view.

On this subject please read the section “Master/slave operation” in the chapter “Product

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 C P

ARAMETERS TO DEVICE) or only the parameter that has just been edited with the aid of the

context menu of the right mouse button (menu C P

ARAMETERS TO DEVICE). With menu LMS400, PARAMETER, SAVE PERMANENT, the parameter set

OMMUNICATION, DOWNLOAD MODIFIED

OMMUNICATION, DOWNLOAD ALL

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 RS232 or RS422. 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 U

PLOAD 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.

Scan line

See line scanner.

SOPAS ET

Configuration software, can be used with Windows 98/NT 4.0/2000/XP/7. Is used for the offline configuration (adaptation to the read situation on-site) and the online operation of the LMS400 in the dialog box.

SOPAS ET setup help

Online help that supports the usage of the SOPAS ET configuration software. The functions of the parameters for the LMS400 are explained in the help and the related value ranges are given. Can be used with an HTML browser, e.g. Internet Explorer and can be opened from SOPAS ET setup.

Aux interface

Auxiliary data interface (RS232) 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.

Online help

Upload

Transmission of the parameter set from the LMS400 to the PC into the SOPAS ET configuration software. The values for the parameters are displayed on the file cards of the configuration software. Prerequisite for the modification of the current parameter set.
