with integrated decoders for all current bar codes used for automatic object recognition.
The modular hoods with integrated connectors MS 34 103/MS 34 105 are intended for the
easy connection of barcode readers of type BCL 34 in a PROFIBUS system and for the
setting of the respective PROFIBUS address (see chapter 7.3 "Address setting").
The modular service display MSD 1 101, which is optionally available, displays operational
data of the BCL 34 and is used as a simple means of access to the service interface.
In particular, unauthorised uses include:
• rooms with explosive atmospheres
• operation for medical purposes
Areas of application
The barcode reader BCL 34 is intended especially for the following areas of application:
• labelling and packaging machines
• space-critical barcode reading tasks
• storage and conveying engineering, in particular for object identification on fastmoving conveyor belts
• pharmaceutical industry

On the barcode readers BCL 34
The bar code readers BCL 34 are high-speed scanners with integrated decoder for all bar
codes currently in use, e.g. 2/5 Interleaved, EAN etc.
The many possible configurations of the device via PROFIBUS modules permit its adaptation to a multitude of reading tasks. Due to the small dimensions of the unit and the short
minimum reading distance, the BCL 34 may also be used in highly constrained spaces.
A special barcode reader with optics version J is available for all ink jet applications. This
reader has been optimised for low contrast barcodes that generally feature gaps. Furthermore, device variants with integrated heating are available.
Information on technical data and characteristics can be found in chapter 5.
AutoReflAct
AutoReflAct stands for Automatic Reflector Activation and permits an activation without
additional sensors. This is achieved by directing the scanner with reduced scanning beam
towards a reflector mounted behind the conveyor path. As long as the scanner is targeted
at the reflector, the read gate remains closed. If, however, the reflector is blocked by an
object such as a container with a barcode label, the scanner activates the read procedure,
and the label on the container is read. When the path from the scanner to the reflector has
cleared, the read procedure has completed and the scanning beam is reduced and again
directed onto the reflector. The reading gate is closed.

Modular hoods with integrated connectors MS 34 103/MS 34 105
The modular hoods with integrated connectors are necessary accessories for connecting
a BCL 34 in a PROFIBUS system. They are used to feed through the PROFIBUS connections, set the PROFIBUS address, and supply voltage to the BCL 34.
MS 34 103
The MS 34 103 offers the following interfaces:
• PROFIBUS In (HOST/BUS IN)
• PROFIBUS Out (BUS OUT)
• Voltage supply (PWR) and 1 switching input and output each (SW IN/OUT)
Figure 4.2:

In addition, the MS 34 105 offers the following interfaces:
• Service interface (SERVICE)
• 1 further switching input and output each (SW IN/OUT)

Modular Service Display MSD 1 101
The modular service display is used to display the reading and operational data on the one
hand, and as simple access to the service interface on the other. The RS 232 service interface of the BCL 34is tapped in this case and is made available at the 9-pin sub D connector
of the MSD (for further information see page 30).
Figure 4.4:
MSD 1 101
The MSD can be operated in different display modes which are stored in the parameter set
of the BCL. The required parameter for setting up the display mode can be altered via the
service interface. The LCD display contains two lines with 16 characters each. There are
3 display modes:
1.
Single line:
a result is output in one line. If the information is longer than 16 characters, the characters > 16 are cut off. This means that two results may be output on the LCD display.
Double line:
a result is displayed over both lines. Thus, only one result is visible in the display.
Depending on the size:
if a result is > 16 characters, both lines are used
if a result is < 16 characters, one line is used and two results are displayed

To connect to the MS 34 105, an 8-pin cable (M12) with a length of 2m is used (see
chapter 6 "Accessories / Order Designation").
Description
The input can be specified as a PT commentary or in the BCL Config parameter list, e.g.,
PT0001610x.
Using the maintenance display, new settings for the BCL can be tried quickly and easily,
without having to project these settings via the PROFIBUS. If these settings are to be
accepted for standard operation, these must be configured via PLC.
Notice!
With very few exceptions, the BCL 34 is configured via the PROFIBUS connection
group.Parameters which were set via the service interface are, therefore, overwritten in
PROFIBUS operation by the parameters stored in the project. If parameters in the project
were not explicitly changed, the corresponding default parameters are transferred.
In the BCLConfig configuration software, the parameter input fields which can be overwritten by the PROFIBUS are displayed with a blue background. Parameter input fields which
are not overwritten by the PROFIBUS are displayed with a white background.
If these parameters were changed, they are stored in one of the available parameter memories in the MS 34. They are, thus, safely stored even if a BCL 34 is replaced.

Device Construction and Components
A modular hood of type MS 34 103 or MS 34 105 with integrated connectors is part of
every BCL 34. The two hoods with integrated connectors are used to connect the BCL 34
to the PROFIBUS. For this, they feature one HOST/BUS IN and BUS OUT connection each,
as well as an internal switch for address setting.
If only the connection to the PROFIBUS is intended, type MS 34 103 is sufficient.
If, in addition, switching input and output or a modular service display are to be connected,
an MS 34 105 is required. Although switching inputs and outputs are available on the
voltage supply connector, the switching inputs of the MS 34 105 have the advantage that
a standard sensor connector can be used.

Automatic reflector activation "AutoReflAct"
The AutoReflAct function uses the scanning beam to simulate a photoelectric sensor and
thus permits an activation without additional sensory mechanism. This is achieved by
directing the scanner with reduced scanning beam towards a reflector mounted behind the
conveyor path.
As long as the scanner is targeted at the reflector, the read gate remains closed. If,
however, the reflector is blocked by an object such as a container with a bar code label,
the scanner activates the read procedure, and the label on the container is read. When the
path from the scanner to the reflector has cleared, the read procedure has completed and
the scanning beam is reduced and again directed onto the reflector. The reading gate is
closed.
Notice!
autoReflAct does not function if the bar codes which are to be read are put on reflecting
surfaces, e.g. foils.

Specifications
Our recommendation:
• Use BCL 34 R1x100
• AutoRefl mode with or without reading gate control (single)
The maximum distances between the reflector and the BCL depend on the reflector used.

7.2.1
Arrangement of devices
Selecting a mounting location
In order to select the right mounting location, several factors must be considered:
• Size, orientation, and position tolerance of the barcodes on the objects to be
scanned.
• The reading field of the BCL 34 in relation to the barcode module width.
• the resulting minimum and maximum reading distance from the respective reading
field
For specific information, please refer to chapter 5.4.
Notice!
The best reading results are obtained when
• the barcode is moved in a plane that is parallel to the reading window
• the reading distance lies in the middle area of the reading field
• you do not use high-gloss labels.
Notice!
TNT 35/7-24V
On the BCL 34, the beam is not emitted perpendicular to the cover of the housing, but with
an angle of 10° towards the top. This angle is intended in order to avoid a total reflection of
the laser in the case of glossy labels. For highly reflective surfaces, this angle may be widened by tilting the BCL.

Mounting location
ª When selecting a mounting location, pay attention to
• maintaining the required environmental conditions (humidity, temperature),
• possible soiling of the reading window due to liquids, abrasion by boxes, or
packaging material residues,
• lowest possible chance of damage to the scanner by mechanical collision or
jammed parts.
Mounting outdoors/devices with integrated heating
When mounting outdoors or for devices with integrated heating, also observe the following
points:
• Mount the BCL 34 in a way which provides maximum thermal isolation to the
machine foundation plate, e.g. using rubber-bonded metal.
• mount in such a way that the device is protected from draughts; mount additional
shields if necessary.
• when using outdoors, we recommend mounting in an additional protective housing.

Connection
Attention!
Do not open the device yourself under any circumstances! There is otherwise a risk of uncontrolled emission of laser radiation from the device. The housing of the BCL 34 contains
no parts that need to be adjusted or maintained by the user.
Before connecting the device, be sure that the supply voltage agrees with the value printed
on the nameplate.
Connection of the device and maintenance work while under voltage must only be carried
out by a qualified electrician.
The power supply unit for the generation of the supply voltage for the BCL 34 and the respective connector units must have a secure electrical insulation through double insulation
and safety transformers according to DIN VDE 0551 (IEC 742).
Be sure that the functional earth is connected correctly. Unimpaired operation is only guaranteed when the functional earth is connected properly.
If faults cannot be corrected, the device should be removed from operation and protected
against possible use.

General Information
The BCL 34 with MS 34 103/MS 34 105 was developed as a PROFIBUS device. The functionality of the device is defined via parameter sets which are clustered in modules. These
modules are included in a GSD file, which is supplied as an integral part of the device. By
using a user-specific project tool, such as, e.g., Simatic Manager for the programmable
logic control by Siemens, the required modules are integrated into a project during
commissioning and its settings and parameters are adjusted accordingly. These modules
are provided by the GSD file.
All input and output modules described in this documentation are described from the
controller's perspective:
• Input data arrives at the controller
• Output data is sent out by the controller
Preparing the control system for consistent data transmission
During programming the control system must be prepared for the consistent data transmission. This varies from control system to control system. The following possibilities are
available for the Siemens control systems.
S7
The specific function blocks SFC 14 for input data and SFC 15 for output data must be integrated in the program. These are standard function blocks and are used to facilitate
consistent data transmission.
S5 with IM 308C
• Up to Release 5 together with Comprofibus software up to Release 2 and
• Release 6 and above together with Comprofibus software Release 3 and above
Here, the function block FB 192 must be integrated, which is used to transmit the
consistent data.
S5 with IM 308B
With the IM 308B consistent data transmission must be programmed via load transfer
commands.

GSD File
The GSD file can be found on the disc supplied with this documentation. It is named
Leuz05d8.GSD.
This file stores all the data required for the operation of the BCL 34. These are device
parameters for reading barcodes, PROFIBUS operation parameters, and the definition of
the control and status bits. If parameters are changed in the project, for example, these
changes are stored in the project, not in the GSD file.
The GSD file is a certified part of the device and must not be changed manually. The file is
not changed by the system either.
8.1.2
Permanently defined parameters (device parameters)
On the PROFIBUS, parameters may be stored in modules or may be defined permanently
in a PROFIBUS participant.
The permanently defined parameters are called "common" parameters or device-specific
parameters, depending on the project tool.
Hilscher Master Controller
In SyCon, the permanently defined parameters are set via "slave configuration" Ö
"parameter data" Ö "common".
The module parameters are set via "slave configuration" Ö "parameter data" Ö "module".
Simatic S7 Controller
In Simatic Manager, the permanently defined parameters are set via object properties of
the device.
The permanently defined parameters in the BCL 34 which are available independently of
the modules, are listed below.
Notice!
In the following detailed descriptions of the modules you will find cross references (CR) to
device parameters (#) and to parameters and input/output data of other modules in
the last column of the tables. These are directly related to the parameter described. These
cross references must be observed during configuration.
The individual modules are numerically labelled from 1 … 50.
The parameters and input/output data within a module are alphanumerically labelled
from a … z .

Structure of the project modules
In the current version, a total of 50 modules are available for use. A "Device Module" ( see
"Permanently defined parameters (device parameters)" on page 45) is used for basic
scanner configuration and is permanently integrated into the project. A further 50 modules
may be included into the project according to requirements and application.
The modules fall into the following categories:
• Parameter module for the scanner configuration
• Status or control modules that influence the input and output data.
• Modules that may include both parameters and control or status information.
The category of each module is marked with a cross in the overview.

Module 5
The module permits the definition of barcode types with a different number of digits and/or
code type in the reading gate and provides the necessary input data.
If several barcodes are read in a reading gate, these barcodes are transmitted in sequence
in order to save memory in the controller. This requires a handshake, which is achieved by
using the input and output data.
50
BCL 34
Leuze electronic
PROFIBUS
Example:
3 barcodes are to be transmitted. Accordingly, the parameter "number of barcodes" is set
to the value 3. After a reading gate activation (module 18) and the reading of 3 barcodes,
the first barcode is transmitted automatically. This barcode is available from the decoding
results module (module 21 - 27).
In the input byte "number of decoding results" of module 5, the BCL indicates that there
are still 2 decoded barcodes in the BCL's buffer memory. If the first barcode in the
controller has been processed or stored, the BCL receives an acknowledgement via the
output bit "acknowledge". This bit is a toggle bit, i.e., each edge transition ( 0->1 and 1->0)
is an acknowledgement.
The BCL now immediately tries to transmit the next barcode from the buffer memory. On
the one hand, the controller recognises the successful transmission by the change of the
input byte from 2 to 1, on the other hand, it is essential that the "new result" bit and the
associated toggle bit in the decoding results (module 21 -27) are evaluated. Only if a new
barcode is actually present in the decoding results and has been processed or stored, the
next acknowledgement should be carried out via the acknowledge bit. If this is not taken
into account, decoding results may be lost.
It is also important that all transmitted barcodes are really acknowledged. It is better to
acknowledge the last barcode one time too many than not at all. Otherwise, the buffer of
the device (module 20 -27) may overflow quickly.

Pharmacode Properties
Module 10
The module defines additional properties of the code type Pharmacode.
As a matter of principle, the parameters described in the following should be changed only
if you are familiar with the characteristics of the Pharmacode, as incorrect settings may
cause a misinterpretation of barcodes. The difficulty is that the bar widths of the narrow and
wide bars used in the Pharmacode are not defined as fixed widths, but feature a relatively
high tolerance range. This means that even within a barcode, deviations may occur, e.g.,
when wide bars of different widths are used.
Parameters
Parameter
Description
Rel.
addr.
The parameter specifies the minimum width ratio
between wide and narrow bars of the code type Pharmacode.
Bar width
A standard value of 185 means that a wide bar must be
ratio
1.85 times wider than a narrow bar.
The parameter specifies the minimum ratio of bar and
b
gap width for the code type Pharmacode.
Verification
A standard value of 75 for wide bars means that a wide
of bar widths
bar must be 0.75 times wider than a gap.
The parameters specifies the size of the safety distance
c
in per cent in the width value of narrow and wide bars.
At a standard value for the verification of bar width of 75
Bar width
(see above) and a bar width distance of 5, a wide bar
distance
must be at least 0.8 times as wide as a gap, and a narrow bar must be not more than 0.7 times as wide.
The parameter specifies the maximum width relationd

AutoReflAct (automatic reflector activation) Module 15
The AutoReflAct function uses the scanning beam to simulate a photoelectric sensor and
thus permits an activation without additional sensory mechanism. This is achieved by
directing the scanner with reduced scanning beam towards a reflector mounted behind the
conveyor path. As long as the scanner is targeted at the reflector, the read gate remains
closed.
If, however, the reflector is blocked by an object such as a container with a bar code label,
the scanner activates the read procedure, and the label on the container is read. When the
path from the scanner to the reflector has cleared, the read procedure has completed and
the scanning beam is reduced and again directed onto the reflector. The reading gate is
closed.
Notice!
The AutoReflAct function should not be used in connection with Module 46 (Alignment
Mode 1) as this may lead to erroneous functionality.

Explanations regarding the parameter "Sequence"
Generally, there is a distinction between the following reference barcode comparisons:
• Comparison in the decoding sequence:
Each currently decoded barcode is compared with all RBCs (starting with the first).
• Comparison in the sequence of the activated RBCs:
The first decoded barcode is compared only with the first RBC, the second decoded
barcode only with the second RBC and so on.
The possible comparison sequences are described in the following table:
Value Meaning
1
Comparison in the decoding sequence –
The comparison result is positive if at least one barcode corresponds to one RBC.
2
Comparison in the decoding sequence –
The comparison result is positive if each decoded barcode corresponds to at least one RBC.
3
Comparison in the sequence of the activated RBCs –
The comparison result is positive if at least one barcode corresponds to one RBC.
4
Comparison in the sequence of the activated RBCs –
The comparison result is positive if each decoded barcode corresponds to the RBC it was
compared with.

First decoded barcode with RBC6
17
First decoded barcode with RBC7
18
First decoded barcode with RBC8

22
Comparison in the decoding sequence –
The comparison result is positive if each decoded barcode corresponds to at least one RBC.
(Number of the received barcodes must correspond to the number deposited in the parameter
"number of barcodes per reading gate" (Module 5)).
23
Comparison in the sequence of the activated RBCs –
The comparison result is positive if at least one barcode corresponds to one RBC. (Number of the
received barcodes must correspond to the number deposited in the parameter "number of barcodes
per reading gate" (Module 5)).
24
Comparison in the sequence of the activated RBCs –
The comparison result is positive if each decoded barcode corresponds to the RBC it was compared with. (Number of the received barcodes must correspond to the number deposited in the
parameter "number of barcodes per reading gate" (Module 5)).

8.3.18 Decoding Result
Modules 21 to 27
The following describes various modules for the output of decoding results. They have the
same structure but different output lengths. The PROFIBUS module concept does not cater
for modules of variable data length. Accordingly, the modules are to be regarded as alternatives.
The module defines the transfer of the actually decoded reading results. The data are transmitted consistently over the entire range. If one of the modules 21 to 27 is used, the status
information of the selected module must also be used. The modules only work consistently
or synchronously in themselves.

8.3.19 Interlinked read result
Module 33
If this module is configured, several decoding results are interlinked into a single read
result. A condition for linking is the increase of the number of barcodes in the Module 5
multilabel. In this case, the additional information regarding the barcode in Module 33
toModule 45 always refers to the last decoding result in the interlinked read result. Unless
all barcodes are decoded, the most recent decoding result may be a non-reading, i.e., the
additional information regarding the barcode refers to the non-reading. An application of
the interlinked read result is, for example, in the disc application. In this application, several
discs are located on top of a box and labelled with short (e.g., two-digit) barcodes. Only
one barcode is visible for each disc and can be decoded. To avoid having to transfer these
short barcodes individually to the control, an interlinking into a single read result can make
sense. The decoding results can be partitioned with the configurable delimiter.
Parameters
Parameter
Description
a
A configured delimiter (value not equal to 0) is inserted
between the decoding results.
For example, if a dot is configured as a delimiter, the following read result could be transmitted to the control:
“02.10.2008“; without delimiter (value 0) this read result
would be transmitted to the control as “02102008“.

Fragmented Reading Result
Module 34
The module defines the transfer of fragmented reading results. To occupy few i/o-data, the
reading results may be split into several fragments with this module. The fragments can
then be transmitted one after another with a handshake.
Notice!
The modules 21 to 27 are designed to transmit data of a length of up to 28 bytes only. If you
would like to transmit longer data, this can be achieved by using Module 34.

However, parameters are only reset permanently if they have been altered via BCL-Config,
or if the device is connected to a hood with integrated connectors using the wrong parameter set.
After the reset function has been activated, the device carries out a reset and is freshly
configured on the PROFIBUS. Potentially incorrect parameter settings via PROFIBUS

8.3.35 Switching output expansion
Module 49
This module defines additional parameters for the switching output (Module 14) and should
only be used in conjunction with this module. The parameters permit the new event counter
function for the switch-on function [EF] of the switching output to be used.
If, for example, the switching output is to be activated after four invalid read results, the
"comparative value" is set to 4; in Module 14, the respective switch-on function must be
configured as "invalid read result".
The comparison mode parameter can be used to define whether the switching output is
activated only once in the case that the event counter and comparative value fulfil the
"parity" condition, or if it is activated multiple times, on each successive event after the
"parity" condition is met.
The event counter can always be reset by using bit 1 in the output data of Module 14. In
addition, the parameter "reset mode" permits an automatic reset once the "comparative
value" is reached. Automatic resetting upon reaching the comparative value always results
in the switching output being switched once independent of the comparison mode parameter.
The standard switch-off function [AF] at "reading gate start" is unsuited for this application
since it causes the event counter to be reset on each reading gate start. It is recommended
that all switch-off functions be deactivated.
Parameters
Description
a
If the number of activation events of the
selected switch-on function reaches this
comparative value, the switching output is
activated. A deactivation event of the selected
switch-off function resets the counter.
Specifies whether the switching output
switches only on parity (once) or also in the
event of greater or equal to (multiple times)
after the comparative value is reached.
Specifies whether the counter (Event Counter)
is reset only by the reset bit and the selected
switch-off function, or if the counter should
be automatically reset after the comparative
value is reached.

Commissioning
10.1
Measures to be performed prior to the initial commissioning
ª Before commissioning, familiarise yourself with the operation and configuration of the
device(s)!
ª Before switching on, recheck all connections and ensure that they have been properly
made.
Loading and Configuration of Modules
Gather the required modules for the BCL 34 in your PLC software and configure them as
necessary. Further information regarding the individual modules is provided in chapter
"PROFIBUS" on page 44.
Configuration examples together with the required modules and flow diagrams may be
found in chapter "Example configurations" on page 88.
Setting the device address
The device address is set via switches in the modular hood. For setting instructions refer
to chapter 7.3.
ª Set the device address according to the address previously selected in the configuration.
10.2
Function Test
"Power On" test
After connecting the operating voltage, the BCL 34 performs an automatic "Power On"
function test. Subsequently, the green LED lights up in the optics window of the BCL 34.
Interface
A red/green LED for checking the interface function is located on the underside of the
modular hood. The significance of the individual LED states may be found in table 5.2 on
page 18.
Problems
Should a problem persist after checking all electrical connections and settings on the
devices and host, please contact a Leuze service office near you (see the back page of this
operating manual).

Maintenance
10.2.1 Service Operating Mode
If the BCL 34 is operated with a modular service display, its functioning can be checked
with the help of the operating mode Service. The following operational parameters are
made available on a separately wired RS232 interface via the 9-pin sub-D connector of the
MSD – independent of the BCL's configuration for standard operation:
•
•
•
•
•
•
transfer rate 9600 baud
no parity
8 data bits
1 stop bit
prefix: STX
postfix: CR, LF
Service interface active
The service interface is activated via a switch in the modular service display or via
Module 50 (RS 232).

Maintenance
11.1
General Maintenance Information
TNT 35/7-24V
To test the functioning of the BCL 34 with the user software "BCL-Config (V4.0)" (V3.22),
connect the device to a PC or terminal via the serial interface. For this, you need a crossed
RS 232 connection cable (null modem cable) that provides the connections RxD, TxD and
GND. A hardware handshake via RTS, CTS is not supported at the service interface.
Usually, the barcode reader BCL 34 does not require any maintenance by the operator.
Cleaning
Should it become soiled, clean the glass window of the BCL 34 with a soft cloth.
Notice!
Do not use aggressive cleaning agents such as thinner or acetone for cleaning the device.
11.2
Repairs, servicing
Repairs to the device must only be carried out by the manufacturer.
ª Contact your Leuze distributor or service organisation should repairs be required.
For addresses, please refer to the back page of this operating manual.
