1.2 Warning signs

The sign Caution warns against dangers to health which may occur if this advice is not observed

The sign Attention warns against possible damage to the device

The sign Information points to important information.

This sign indicates that special environmental protection guidelines must be observed when disposing of the device.

1.3 General information

The laser distance meters of the LLD-500 series have been designed for application in industrial facilities. Within the measuring range of 15 cm to 200 m the sensors work with a high accuracy of up to + 2.1 mm and at

a variably adjustable measuring frequency of maximally 100 Hz.

Due to the excellent optical measuring performance of the LLD the sensors can be used both indoors and outdoors, even in case of a high percentage of constant light. Moreover, they can be used for measuring very hot

surfaces such as glowing steel.

When great distances of more than 50 m need to be measured, the sensor can be used in combination with a reflector. Simple assembly and standard interfaces enable the quick integration of the device into complex

measuring and control systems.

Data can be displayed and parameters can be set using an internal keypad and display or an external communi-

cation program.

2. Safety advice

2.1 Basic safety advice

Please read the safety and operating advice carefully, and observe the advice when operating the LLD-500 laser distance measurement device.

Danger, laser radiation. The LLD-500 must not be opened unauthorized, otherwise laser radiation can be emitted that can cause injuries to the eyes. Please observe all information and guidelines for operating the laser.

Danger, electric shock The LLD-500 may only be opened for repair purposes by the manufacturer. If the device is opened arbitrarily without authorization, all warranty claims will expire.

The operating and storage conditions ( chapter 9) have to be observed. The non- observance of this advice and the adverse use of the device can lead to injuries of the user or to damage of the device.

Connectors may not be plugged or unplugged when voltage is applied. All installation work may only be carried out when no voltage is applied.

The device may only be operated as intended and in faultless condition. Safety installations must not be rendered ineffective.

Safety and warning signs must not be removed.

Protection degree: In accordance with the protection degree IP67, the LLD-500 is protected against jet water and dust, and against short submersion into water.

When operating the device under extreme outdoor environmental conditions, the use of additional weather protection is recommended (e.g. a cover plate with a short distance to the LLD-500). Rapid temperature changes can lead to humidity entering the device. If the device is exposed to humidity, the temperature difference between the de- vice and the environment may be ± 5K maximum.

The device is not shatter-proof. Do not let the device fall onto the ground, and avoid any agitation.

The device may not be used in explosive environments; otherwise there is the danger of damage to the LLD-500 and the surrounding equipment, and of injuries of the user.

2.2 Laser class

Based on the standard EN 60825-1:2014 the LLD-500 is in correspondence with laser class 2. When looking into the laser beam accidentally and for a short moment, the eye will be protected by the eyelid closing reflex. The eyelid closing reflex can be affected by pharmaceuticals, alcohol and

other substances.

2.3 Transport and storage

The LLD-500 laser distance meter is delivered in standard packaging. All kinds of transport are permitted. It is recommended to store the unit inside the transport packaging until it is used.

Please observe the storage conditions.

2.4 Cleaning and maintenance

The LLD-500 does not require any maintenance. To ensure trouble-free measurements, the optical surfaces through which the laser beam exits and enters must be free of deposits. Dust can be removed using an air

brush. In case of dirt that is hard to remove, please contact the manufacturer.

The device must not be cleaned using solvents or mechanical tools. Mechanical or electrical modifications of the device are not permitted.

2.5 Service

3. Intended use

3.1 Operating and storage conditions

Operating temperature

- 10 °C … + 60 °C (special type - 40 °C … + 60 °C)

Storage temperature

- 40 °C … + 70 °C

Humidity

15 % … 90 %, non-condensing

Depending on the type of device

Explanation: The values specified as operating temperature descripe the temperature range in which the LLD can be used according to the specification.

The operating temperature refers to the internal temperature of LLD and could be approx…. 10 kelvins above the ambient temperature (see EN 60204-1).

If LLD-500 operates near the upper limit of temperature range (ambient temperature > 40 °C), the probability of measuring errors will be increased.

A permanent operation of LLD-500 at higher temperatures (ambient temperature > 40 °C) shortens the lifetime of the sensor. For permanent operation of LLD-500 it is recommended not to exceed an operation temperature of 50 °C, which correlates to a maximum ambient temperature of 40 °C.

3.2 Improper use and possible error sources

• The unit may be used only as prescribed.

• Please do not remove any labels and type plates.

• Repair work must not be performed by the user. In case of questions or doubt, the manufacturer is to

be consulted. For contact data see section 2.5.

• In order to obtain correct measuring values the following advice is to be observed:

1. Measurements against the sun or onto surfaces with low reflectivity in very bright environments can result in faulty measurements.

Measurements through glass, optical filters, Plexiglas or other translucent materi

als are possible to

a limited extent but can result in measurement errors.

3.3 Warning signs and type plates

Laser label The LLD-500 works with a class 2 laser.

When looking into the laser beam accidentally and for a short moment, the eye will be protected by the eyelid closing reflex. The eyelid closing reflex can be affected

by pharmaceuticals, alcohol and drugs.

This device may be used without any additional safety

precautions when the following advice is observed:

► Do not look directly into the laser beam. ► Do not look at the laser beam using optical

instruments.

► Do not point the laser beam at other people.

5. Installation and commissioning

5.1 Mechanical installation conditions

There are two different ways to install the LLD-500 laser distance meter. 3 M6 socket cap screws are included in

the scope of delivery.

1. Fastening through one of the side faces

Two M6 screws + washer spring + washer

2. Fastening through the housing bottom

Three M6 screws + washer spring + washer

3. Cable connections

In order to ensure variability in the application of the device, connecting cables with straight or angular connectors are available (also see chapter 4.2). The cables are not included in the scope of delivery. Please order them as required.

4. Attaching the light protector (optional)

An optional light protector is available for application in very bright environments. Part number: 012890-250-12 The light protector is attached to the front face (laser beam emission point) using three M3x6 screws. The screws are included in the scope of delivery of the light protector.

When the device is used outdoors under extreme environmental conditions, an additional weather protector (e.g. cover plate in a small distance to the LLD) is recommended. Other-

wise, moisture may enter the device despite the IP67 due to rapid temperature changes.

5.2 Commissioning

5.2.1 Preparatory work prior to installation

► Remove the packaging of the LLD-500. ► Check the delivery for completeness. ► Examine the device and the accessories for damage. ► Examine the connections and cables for damage.

5.2.2 Installation work checklist

The following table suggests a commissioning procedure for the LLD-500, without claiming to be exhaustive. The user is responsible for the application-specific cabling and for the parameterization of the Profibus

(optional), particularly of the slave address. Thus, the latter are taken as a given.

Where the LLD-500 is taken into operation for the first time, we recommend carrying through the configuration

steps at a laboratory or office.

The device can be configured using either the display or a communication program. For example, the program

HyperTerminal (included in Win32 operating systems) or any other communication program can be used.

In order to parameterize the device using a communication program, the LLD-500 must be connected to supply

voltage and a PC (also see Fig. 2 in chapter 4.4). SSI and/or Profibus need to be set separately.

No.

Work step

1 Unpack the LLD-500, check it for damage.

2 Mount the LLD-500 at the target location (with 2 screws through the side face or 3 screws through the bottom) --> see 5.1. Roughly direct it at the target surface.

Final visual check

6. Parameter setup and measuring operation

6.1 General information

The LLD-500 is parameterized using the serial interface or the display. Precondition for programming via serial

interface is a connec-tion provided by a terminal program (e.g. HyperTerminal --> see chapter 7). The set parameters are stored in an EEPROM.

The last entered data will be available upon restarting.

The output values shown in the manual are examples. They may vary depending on the settings and environ-

mental conditions. Whenever an incorrect or incomplete command is entered, the following responses are shown:

The input does not contain any parameter or command. e.g.: HELLO<ENTER>

Parameter with current value Entry of a parameter with incorrect figure/ parameterization

e.g.: Input: SAxxx<ENTER> Output: SA 10 (where SA = 10 prior to input)

6.2 Measurement involving moving targets

Where measurements involve a moving object or the LLD-500 is moved during measuring, this will have an im-

pact on the accuracy of the measured value. This must be observed particularly when calculating average values (parameter SA).

Measurement jumps and/or considerable changes in the reflectivity of the target surface can prolong the measurement period.

In case of a fixed measuring frequency (parameter MF), this may result in no measured value being generated

within the predefined time. A warning or error message will be displayed instead.

6.3 Identification

6.3.1 ID recognition

When entering the command ID, the LLD-500 will respond by displaying the manufacturer’s data in the following order: Device type, serial number, manufacturer’s part number, firmware version, time stamp.

Example: LLD-500 130004 012890-001-22 V5.14.0422 13-10-02.13:59

6.5 Operating modes

6.5.1 DM – Individual distance measurement

The LLD-500 will perform exactly one measurement and then wait for new instructions. The duration of the measurement depends on the number of preset measuring values SA and the preset measuring frequency MF.

Input: DM

Typical parameter settings

MF0, SA1, DM

Execute single measurement, allowing for a sufficient period of time as needed to determine the distance to a static (during the measurement) target object.

MFx, SA1, DM

Execute single measurement, allowing for a period of time of maximally 1 / x seconds to reliably determine the distance to a static (during the measurement) target object.

6.5.2 DT – Continuous distance measurement (distance tracking)

The LLD performs a continuous measurement. The measurement can be interrupted by a command: Display STOP RS232/422/485 Escape = 0x1B RS232/422/485 command SDT = 0x53 0x44 0x54

The output frequency of the measured values depends on the selected parameters MF and SA. The DT mode works with high measuring stability in the collection of the measured values, even in case of

beam interruptions and discontinuous motion sequences of the target. Input: DT

Full measurement (new adjustment of frequencies to define the unambiguous range) will be forced after beam interruptions.

Remarks: In case of poor target reflectivity, it cannot be guaranteed at 100 % that the respective measurement will be

completed within a period of time of 0.01 s (100 Hz). Thus, a warning will be generated. --> w1910. The output frequency will remain constant. The frequency of warnings and error messages will increase if MF > 20 Hz. In addition an output of wrong distance values could be happen with bare probability. For optimal results the recommendation is to set MF to 20 Hz or lower in mode DT.

There are the following alternatives:

1) A variable output frequency can be selected for surfaces with low reflectivity. The LLD will keep measuring until a representative distance value can be determined. Normally, the measuring period ranges between 0.01 and 3 seconds (no average determination).

2) Where a measured value output of 100 Hz is not needed, a lower measuring frequency can be set via the parameter MF. While this parameter influences the output frequency, it has no impact on the internal measuring frequency. The output frequency can also be reduced by using the average determination function. For example, if an average determination covering 5 measured values (SA 5) includes a warning, only 4 measured values will be used for average determination. Where there is only one measured value, there will be one output. The output of warnings is avoided.

The table below shows exemplary the ranges and accuracies in relation to the target surface for outdoor applications. The conditions for the measurements were environmental temperature of +25°C and ambient light around the target of 1.2 kLux. The measuring range in an application depends on a large number of factors, e.g. target reflectivity, stray light, output frequency and other environmental conditions. Before integration of LLD in a whole system special tests are necessary, to get optimal application results.

1in consideration of parameterization in accordance with chapter 6.4.9 and 6.4.10 Measurements on targets with low reflectivity may cause error messages.

If the output frequency is over 20 Hz the fault rate will increase significantly.

w1910

Generating a measured value within the predefined period of time was impossible (laser searches for suitable parameterization after distance jump/surface change). MF too high.

e1201/e1203

No laser reflex received (unsuitable / poorly reflecting surface). Reduce the value of the measuring frequency MF.

e1206

Target surface too bright or ambient light too intensive.

e1207

Distance is outside of the measurement window MW.

6.5.3 CT – Continuous tracking

The LLD-500 performs an uninterrupted continuous measurement, adjusting the laser parameters (unambiguous ranges) in relation to the target only every 6 seconds or when an obvious distance measurement error has occurred. The measuring accuracy for frequencies > 20 Hz is higher in the mode CT as in the operation mode DT.

Areas of application:

► Scanning of static targets. ► Quick measurements on hot surfaces. ► Tracking of continuously quickly moving targets (e.g. crab [crane], vehicle)

The tables below show the ranges and accuracies in relation to the target surface for outdoor applications. The conditions for the measurements were environmental temperature of +25°C and ambient light around the target of 1.2 kLux. The measuring range depends on target reflectivity, stray light, output frequency and environmental conditions.

Distance jumps or laser beam interruptions can result in faulty measurements! The warning w1912 is issued.

6.6 Q1/Q2/Q3 – Switching output

The switching outputs Q1, Q2 and Q3 show distance information as logic switching information. They signalize when values are above or below a preset switching range subject to hysteresis. Hence, they are perfectly suitable for the direct further processing of monitoring variables such as filling level or object detection. Parameterization is done via the serial interface.

A load resistance of > 150 ohms/ 6W (30 V max. operating voltage: 0.2 A max. load current) must be switched against GNDpower at the switching output. It is essential that the load current of 0.2 A is not exceeded.

Typical resistance: 1 kOhm against GND

The LLD does not check the settings of Q1, Q2 and/or Q3 for plausibility.

6.7 QA – Analog output

The analog output enables the normed, analog transmission of distance data across large distances using a two-wire line. The current of 4...20 mA impressed in the line is proportional to the measured distance within an adjustable distance interval. Parameterization is done via the serial interface.

The current to be put out when faulty measurements occur is parameterized using the command SEx. Properties of the analog output:

► 4mA ... 20 mA ► Indication in case of an error: 3 mA or 21 mA or last measured value (selectable via the parameter SE) ► Resolution: 12 bit D/A converter

Where current/ voltage is to be converted, a load resistance of 100 ohms < R < 500 ohms/ 0.5 W is to be switched between current output QA and GND. Capacitive load < 10 nF Operating voltage > 12

The measurement window MW also applies to the analog output. The LLD does not check the QA settings for plausibility. The user is responsible for correct parameterization!

Example 1: A measuring range from 1 m up to 15 m shall be specified. 1 m should be the lowest current. -> x = 1 m = 4 mA / y = 15 m = 20 mA

6.8 TRI + TRO Trigger

6.8.1 Trigger function

The LLD-500 Trigger could be used as input or output.

1. Trigger input / external trigger function: External trigger signal will be sent → start of measurement DM in accordance with parameter TRI.

2. Trigger output / e.g. connection between 2 LLD-500: The output trigger signal of the 1. LLD-500 (parameterized with TRO) starts a single measurement DM of the second LLD-500 (parameterized with TRO).

Differences between trigger input and trigger output

Important is the parameter y of TRI and TRO.

TRI y > 0 / TRO y = 0 Trigger input

The measurement starts after an external trigger impulse.

TRI y = 0 / TRO y >0 Trigger output

LLD-500 sends a trigger impulse to the second device.

The parametrization of the trigger connection is carried out via the serial interface or the internal display.

Voltage levels for the trigger signals Low level 0 – 1.5 V

High level 3 – 30 V Threshold 2.25 V Hysteresis 0.1 V

Maximum frequency of external trigger signal: 1 Hz If the trigger frequency is too high, no measurement value can be determined. The output is E1203.

The trigger frequency must be reduced.

Measurement frequency should be set ≠ 0 (for MF = 0 the measurement frequency is variable).

6.9 Direct controlling of the LLD-500

The LLD-500 can directly be parameterized and set for measurements without an additional PC. Precondition is that it is supplied with voltage through the interface cable. The LLD-500 is ready for operation when the green STATUS LED is lit.

The individual menu items can be selected using 4 membrane keys, each 2 above and 2 below the OLED display. The user language is English.

The display can be deactivated during the measurement. It can be switched on again by pressing key T3 or T4.

Because of internal processing time it can be not guaranteed that all parameter changes will displayed after parameterizing of parameters (e.g. MF, SF, SA) via display input and a following check of the setup with command PA. An action such as start/ stop of a measurement or input of command ID will update the values of parameter PA.

7. Serial interface and communication software

7.1 Transmission protocol

► Interface settings: Asynchronous, 8 data bits, no parity, 1 stop bit ► Transmission protocol format / syntax: 7 bit ASCII ► Proprietary transmission protocol ► Commands are case-insensitive (NO differentiation between lower and upper case). ► Decimal separator in the output of figures is the dot “.” (0x2E). ► The terminator of a command (sending command) is the enter key (0x0D, 0x0A) or Carriage Return

(0x0D) or Line Feed (0x0A)

► Where parameters have several values, they are separated by a space (0x20). ► The response to commands with parameters is the respective command including the parameters. ► The response to commands without parameters is the respective command including the current

parameters.

► The response to commands with parameters outside of the valid value range is the respective

command including the current parameters. The response to unknown commands and faulty parameter formats is a “?” (ox3F).

7.2 Installation of the communication program

HyperTerminal is a terminal program generally included in Win32 operating systems. It can be used as a communication program to parameterize the LLD-500.

Enter the name of the new connection in the dialog box. You can select any name. Confirm with [OK].

Select the serial COM interface in the second dialog box. Upon confirming with [OK] a third dialog box will appear where

the parameter settings for the current HyperTerminal session can be selected.

LLD-500

At this point, baud rate (bits per second) and flow control must be initialized correctly. As soon as the settings in the third dialog box are confirmed with [OK], the terminal window will open.

The status indication in the left bottom corner reads “Connected” when the pre- conditions for communication have been set correctly. As soon as the LLD-500 is ready for operation (power supply, connection with PC), the commands can be entered - e.g.: ID.

A command just entered will be displayed only when the “Local echo” function has been activated.

The function can be parameterized via the menu “File”.

|File | Properties | Setting |

|ASCII-configuration...|

Please note:

Do not tick the check box “Sent lines end with line feed”.

…

End the session with |File | Quit|.

A small window will appear where you are asked if the connection should really be terminated. This question must be responded to by pressing the [Yes] button.

If the current HyperTerminal session has not been saved yet, a small window will appear where you are asked if the session

should be saved. Confirm with “Yes”. HyperTerminal will not have

to be configured again upon restart.

8. Profibus

8.1 ID-Number

The LLD-500 is registrated under ID number 0E36 (HEX) by PROFIBUS Nutzerorganisation e.V.

8.2 Connecting conditions

The LLD-500 can be connected to any Profibus-DP structure. The connected Profibus-DP master has to be able to send a parameterization. The master configuration tool (usually configuration software) must support the parameters of the GSD file (GSD = General Station Description).

8.3 GSD-File

The GSD file is named LDM50E36.GSD. It is a part of the CD LLD User Manual. The current GSD on request. The inclusion of the GSD file into the master configuration tool should be carried out to the documentation of the configuration tool.

LLD-500

8.4 Slave address

The Profibus slave address can be set under consideration of the other Profibus slaves in the range of 0 … 126. The address can be set with command SSAx via the serial interface or via the LLD-500 keys and the GUI (graphical user interface)  see chapter 6.4.21.

The documentation of the master configuration tool will inform how the slave address has to be changed via the master configuration tool. The default address is 4. The slave address will be stored permanently in the EEPROM and will be available even after power failure.

If several slaves are operated on a Profibus master they must have different addresses and have to connect one by one.

8.5 Profibus termination

The Profibus termination is to realize externally. The supply voltage of 5 VDC will be supplied via Profibus OUT. The 5 VDC are isolated galvanically from the power supply (VCC). The maximum load is 100 mA.

The terminator could be ordered with order number 94145.

8.6 Baudrate

The LLD Profibus has an automatic baud rate for the following baud rates: 9.6 / 19.2/ 93.75/ 187.5/ 500 kBaud and 1.5/ 3/ 6/ 12 MBaud.

8.7 Length of segment

The maximum segment length between two Profibus participants depends on the selected baud rate. The following segment length must be observed:

Baudrate

Length of segment

9,6 kBaud …. 93,75 kBaud

1200 m

Cable type A is strongly recommended for connection of different Profibus units. Cable type A has the following properties:

Characteristic wave impedance

135 ... 165 Ω

Capacitance

< 30 pf / m

Loop resistance

< 110 Ω / km

Wire diameter

> 0,64 mm

Wire cross-section

8.8 Profibus Interface

The Profibus interface of LLD is a standard Profibus-DP V0 interface (local peripherals). V0 is the version number. The telegrams are byte-oriented. Bytes are also referred to as Octets in Profibus

standard terminology. From the user’s angle, the description can be restricted to a few telegram types:

► Cyclical data exchange telegrams (DataEx) ► Diagnostic telegrams ► Parameter setting telegrams.

The different Profibus-slaves of the same or similar function are described in profiles. The profiles make it easier for the user to use PB slaves having the same function but coming from different suppliers. For using LLD at the Profibus, the encoder profile of the Profibus is supported. For this LLD serves as linear encoder. Under the encoder profile, LLD can work as Class1 or Class2 (recommended) encoder. All versions are implemented via GSD file. In addition to profile-specific data, the LLD provides specific settings which refer to the control of the laser and to diagnostics.

8.10 Cyclical data exchange – input (slave -> master)

Position data supplied by LLD-500 is signed. The sign can be inverted in the parameter SF (scale factor). The resolution is also defined by SF. The arrangement of octets in the telegrams conforms to the Profibus (big endian), i.e., the MSB comes first, the LSB comes last.

8.14 Tips for start-up (Siemens STEP7)

The programming software must be made familiar with the possibilities of the LLD-500:

► Open the Simatic Manager ► Open HW Config ► Extras – install new GSD file ► Select LDM50E36.GSD

After that LLD-500 can be integrated at the Profibus:

Select DP slave at ‘Other field devices‘– ‘Encoder’ – LLD-500

A Profibus address must be assigned to LLD-500 (in SSA Set Slave Address):

Target system – Profibus – Assign Profibus Address

8.15 Error display

External errors are not displayed at the module.

8.16 Monitoring

Set to a trigger time of 500 ms, a watchdog internal to the PU monitors the functioning of the module. The following functions are monitored:

► the main loop with Profibus request processing ► the laser control ► the update function.

In case of transient errors (ESD, program error…) the module can be started again after a watchdog reset. Each reset increments the watchdog counter by one.

Other reset causes are also counted:

► Spike detection reset ► SW reset ► Programming and debug reset ► Brownout reset (monitoring of the operating voltage) ► External reset ► Power-on reset

8.17 Service program SL5.exe

8.17.1 Overview

The service program SL5.exe supports the commissioning. All settings are made into a SPS directly have to perform according to the specifications of the manufacturer of SPS.

The service program can be purchased along with an USB master of softing. Order number: 95831

After installation of a Profibus master, product of softing, the related drivers (also see 2.4.), the service program for lasers LLD-150-PROF and LLD-500 (SL5.EXE) can be started. The program as such does not need an installation (it is linked statically). Only the papi.dll for the Profibus must be placed in the folder.

Copy the service program SL5.EXE and the papi.dll file in any network folder and execute SL5.EXE.

In the SL5.EXE program, confirm the four big buttons on the left one after the other, starting from top. If a computer contains several PB masters, a master module on the right of the word “Board” can be selected

with the combo-box. The selected master module will be analyzed and its type displayed on the right of it, e.g. PROFIboard PCI or PROFIcard.

1. Press the Connect button The selected board is activated and – if successful - the ‘Go Online’ button enabled. If a problem occurs, open ‘Trace’ with a mouse-click on the ‘Trace’ tab (in the middle of the dialog) for more information on the Profibus. On the right of the word ‘Master:’ an address can be assigned on the Profi- bus with the combo- box of the PB master module. Every address must be unique! Depending on what type of Profibus is connected, different PB masters and PB slaves with ad- dresses in the range 0…125 can be available. Normally, the preset 0 as address of the PB master is okay. The baudrate should be set as a function of the length of the line or masters already active on the bus

2. Press the Go Online button

The PB master will become active on the bus (exchanges the token). If everything is okay, the ‘Scan for

Slave’ button will be enabled after about 2 seconds. Now the bus can be searched for slaves. The

search always begins at address 0. The master address is skipped. To cut the search short, the highest address to be used can be defined.

3. Press the Scan for Slave button A search of the bus is made and the first LLD-500 found is selected as slave. If the slave address (‘se- lect addr :’) is changed, a diagnosis request is sent to the slave and the PNO Ident of the slave dis- played when the reply is received.

4. Press the Data Exchange button The master adopts Operate state, sends a data exchange request to the LLD-500, whereupon the latter activates its laser. The distances measured can be viewed at Distance.

8.17.2 Setting a Profibus slave address at the LLD-500

Perform steps 1 to 3 in chapter 8.17.1. One LLD-500 PI-LB module must have been found at the bus. The Profibus slave address of that module can now be changed to between 0 and 125 but the addresses of other bus users must not be assigned to the module. For this, select ‘old addr:’ the current address and the required new address at ‘new addr:’ Then press ‘Set Addr’. ‘Set Slave address’ (SSA), a Profibus global control, transfers the new ad- dress to the PB slave, which uses the new address henceforth. The new address is stored permanently in the EEPROM and is the new slave address also after a power outage

8.17.3 Parameter-Dialog

The SL5 generates a complete encoder profile specific parameter record, which is transmitted to the slave immediately when a datum is changed (provided it is active on the bus).

(Profibus) parameters cannot be read back. Therefore, the setting of the parameters may not agree with the parameters active in the slave when the SL5 is started.

► Class 2 function: Selection of the slave type according to the encoder profile ► Commissioning diagnostic: Send more than the 6 Byte standard diagnostic (16 Byte as Class1 slave, 61

Byte as Class 2 slave)

► Tracking mode: Mode (trigger) of the laser (DT,CT,TDM) ► Trigger input flank and time spacing: Values are transferred directly to the TRI x y command ► Trigger output flank and time spacing: Values are transferred directly to the TRO x y command ► Averaging: Value is transferred to the SAn command ► An offset can be applied to the measuring value (correction). ► Scale factor: Scaling factor –1000,000... +1000,000. Up to 3 decimal digits are processed. ► Error mode: Selects the distance value in case of an error ► Measure frequency: Measuring time output, 0 means no firm frequency, range 0.0 ...

200.0 with up to 4 decimal digits

► Measure window: Setting of the valid measuring window ► Diagnostic interval: 0=Send diagnostic data only in case of alarm, 1..10000 : Send diagnostic data every

n x 100 ms

► Switched output Q1/2/3: Switching threshold for output n in units of distance – is transferred to Q1/2/3

command

► Analog switched output: min. and max. distance values for 4 and 20 mA

8.17.4 Diag Common

The (general) diagnostic data is in full agreement with the profile standard and is updated by every Profibus diagnostic request. The Common Diag data requires Class2 functionality and the Commissioning diagnostic function. In case of error (Ennnn) or warnings (Wnnnn) an alarm message with all diagnostic data is sent as extended diagnostic. To view temperature and operating time, set the diagnostic interval other than 0. A diagnostic interval of 100 causes an update every 10 secs.

8.17.5 Diag Alarm

Alarm messages of the laser module are sent once as EXT. DIAG. Active alarms are marked X instead of –. Alarms are counted but not stored anywhere. If an error occurs, it is reported as Ext. Diag and then an attempt at reactivating the laser is made. Thus, permanently active errors increment the appropriate error count.

8.17.6 Trace

Here, certain messages will be displayed for diagnostic purpose if problems occur with the Profibus or the PB master in the PC.

8.17.7 Log-File

If required, the SL5 program can write distances and temperature in a log file in regular intervals. The log file

can have a firm name. For this, uncheck the ‘automatic’ box. Select a target folder and a file name with the

Browse button (‘...’). Data will then be written in that file continuously. For longer recording times, the log can be

split into day files. For this, check the ‘automatic’ box. This generates a file by the generic name ‚ L5_yymmdd’

(yy=year, mm=month, dd=day). That file is closed at midnight and a new file generated for the next day. The system time (UTC, GMT) is used as file time.

The file is written with special ‘share’ attributes so that it can be read by other programs (data- bases, control systems...) at the same time. Also see tail programs. Under Values, select the values to be written. Under Time, enter the time spacing between 2 values in minutes and/or seconds.

The log can be started or stopped at any time with Start and Stop.

The message in the messages window contains additional information whether the module is supplying distance or temperature data.
