3 Configuration

Note Along with the interactive configuration with the aid of SOPAS ET, you can also configure the

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.).

Chapter 3

Configuration

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 genera tion 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 co nnection 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 subject please read the chapter “Level Control” of the LMS400 operating instructions.

If you select the Level Control application, additional and different parameters will be displayed:

 see section 3.3 “Position” on page 9

 see chapter 4 “Level Control” on page 26

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.
