Safety regulations
Observe the locally applicable legal regulations and the rules of the employer's liability insurance association.
Qualified personnel
Mounting, commissioning and maintenance of the device must only be carried out by qualified personnel. Electrical work must be carried out by a certified electrician.
Attention, laser radiation!
If you look into the beam path over a longer time period, the retina of your eye may be damaged!
Never look directly into the beam path!
Do not point the laser beam of the BCL 304i at persons!
When mounting and aligning the BCL 304i, avoid reflections of the laser beam off reflective surfaces!
The BCL 304i bar code readers correspond to the EN 60825-1 safety standard for a class 2 laser systems. They also comply with the U.S. 21 CFR 1040.10 regulations for a class II laser product except for deviations pursuant to Laser Notice No. 50, dated July 26, 2001.
Radiant Energy: The BCL 304i uses a low power visible laser diode. The emitted wavelength is 655nm. The average laser power is less than 1mW in accordance with the definition of laser class 2.
Adjustments: Do not attempt any adjustments to or alterations of this product.
Do not remove the protective housing of the bar code reader. There are no user­serviceable parts inside.
The glass optics cover is the only aperture through which laser radiation may be observed on this product. A failure of the scanner motor, while the laser diode continues to emit a laser beam, may cause emission levels to exceed those for safe operation. The bar code reader has protective devices to prevent this occurrence. If, however, a stationary beam is emitted, the failing bar code reader should be discon­nected from the voltage supply immediately.
CAUTION: Use of controls or adjustments or performance of procedures other than specified herein may result in hazardous light exposure.

Below you will find a short description for the initial commissioning of the BCL 304i. Detailed explanations for all listed points can be found throughout this technical description.
3.1 Mounting the BCL 304i
The BCL 304i bar code readers can be mounted in two different ways:
•Via four M4x6 screws on the bottom of the device.
•Via a BT 56 mounting device in the fastening groove on the bottom of the housing.
3.2 Device arrangement and selection of the mounting location
In order to select the right mounting location, several factors must be considered:
• Size, orientation, and position tolerance of the bar codes on the objects to be scanned.
• The reading field of the BCL 304i in relation to the bar code module width.
• The resulting minimum and maximum reading distance from the respective reading field.
• The permissible cable lengths between the BCL 304i and the host s on which interface is used.
• The correct time for data output. The BCL 304i should be positioned in such a way that, taking into consideration the time required for data processing and the conveyor belt speed, there is sufficient time to e.g. initiate sorting operations on the basis of the read data.
• The display and control panel should be very visib
• For configuring and commissioning with the webConfig tool, the USB interface should be easily accessible.
For specific information, please refer to chapter 6 and chapter 7.
le and accessible.
ystem depending
Notice!
The beam exits the BCL 304i as follows for the respective devices:
- line scanner parallel to the housing base
- deflection mirror 105 degrees to the housing base
- oscillating mirror perpendicular to the housing base. The black areas in figure 6.2 are the housing base. The best read results are obtained when:
• The BCL 304i is mounted in such a way that the scanning beam is incident on the bar code at an angle of inclination greater than ±10° … 15° to vertical.
• The reading distance lies in the middle area of the reading field.
• The bar code labels are of good print quality and have good contrast ratios.
• You do not use high-gloss labels.
• There is no direct sunlight.

result module (21-27) must be configured and the BCL 304i must be connected to the PROFIBUS.
If a code is led through the reading field, the code content is decoded and passed to the PLC via the PROFIBUS.

General information
The integrated fieldbus connectivity = i contained in the bar code readers of the BCL 300i series facilitates the use of identification systems which function without connector unit or
gateways. The integrated fieldbus interface considerably simplifies handling. The Plug-and­Play concept enables easy networking and very simple commissioning: Directly connect the respective fieldbus and all configuration is performed with no
For decoding bar codes, the bar code readers of the BCL 300i series make available the proven CRT decoder with code fragment technology:
The proven code fragment technology (CRT) enables bar code readers of the BCL 300i
series to read bar codes with a small bar height, as well as bar codes with a damaged or soiled print image.

additional software.
Device description
With the aid of the CRT decoder, bar codes can also be read without problem in other demanding situations, such as with a large tilt angle (azimuth angle or even twist angle).
Figure 4.2: Possible bar code orientation
With the BCL 304i, configuration is generally performed with the aid of the GSD file. The BCL 304i needs a suitable activation to start
the reading field. This opens a time window ("reading gate") in the BCL 304i for the read process during which the bar code reader has time to detect and decode a bar code.
Alternative activation options include online commands via the host interface and the In the basic setting, triggering takes place through an external reading cycle signal or via the PROFIBUS. An alternative option for activation is the autoReflAct function.
Through the read operation, the BCL 304i collects additional useful pieces of data for diag­nosis which can also be transmitted to the host. The quality of the read operation can be inspected using the alignment mode which is integrated in the webConfig tool.

4.4 Reading techniques
4.4.1 Line scanner (single line)
A line (scan line) scans the label. Due to the opt. opening angle, the reading field width is dependent on the read distance. Through the movement of the object, the entire bar code is automatically transported through the scan line.
The integrated code fragment technology permits twisting of the bar code (tilt angle) within certain limits. These are dependent on the transport speed, the scanning rate of the scanner and the bar code properties.
Areas of application of the line scanner
The line scanner is used:
• when the bars of the bar code are printed in the conveying direction ('ladder arrangement').
•with bar codes having very short bar lengths.
• when the ladder code is turned out of the vertical position (tilt angle).
• when the reading distance is large.
Device description

Device description
4.4.2 Line scanner with oscillating mirror
The oscillating mirror deflects the scan line additionally to both sides across the scan direc­tion at a randomly adjustable oscillation frequency. In this way, the BCL 304i can also scan larger areas or spaces for bar codes. The reading field height (and the scan line length useful for evaluation) depends on the re the oscillating mirror.
Areas of application of the line scanner with oscillating mirror
For line scanners with oscillating mirror, oscillation frequency, start/stop position etc. are adjustable. It is used:
• when the position of the label is not fixed, e.g. on pallets – various labels can, thus, be detected at various positions.
• when the bars of the bar code are printed perpendicular to the conveying direction ('picket fence arrangement').
• when reading stationary ob

4.4.3 Raster scanner (Raster Line)
Multiple scan lines scan the label. Due to the optical opening angle, the reading field width is dependent on the reading distance. Provided the code is located in the reading field, it can be read during standstill. If the code moves through the reading field, it is scanned by multiple scan lines.
The integrated code fragment technology permits twisting of the bar code (tilt angle) within certain limits. These are dependent on the transport
and the bar code properties. In most cases, everywhere a line scanner is used, a raster scanner can be used.
Areas of application of the raster scanner:
The raster scanner is used:
• when the bars of the bar code are perpendicular to the conveying direction ('picket fence arrangement')
•with bar codes with low height displacement
• with very glossy bar codes

4.7 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.
Notice!
Compatible reflectors are available on request.
Device description
As long as the scanner is targeted at the reflector, the reading gate remains clos 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.
Figure 4.12: Reflector arra
The autoReflAct function uses the scanning beam to simulate a photoelectric sensor and thus permits an activation without additional sensor system.
4.8 Reference codes
The BCL 304i offers the possibility of storing one or two reference codes. It is possible to store the reference codes via the webConfig tool or via the PROFIBUS. The BCL 304i can compare read bar codes with one and/or both reference codes and
execute user-configurable functions depending on the comparison result.

5.2 Heating models of the bar code readers
The BCL 304i bar code readers are optionally available as models with integrated heating. In this case, heating is permanently installed ex works. Self-installation on-site by the user is not possible!
Features
•Integrated heating (permanently installed)
• Extends the application range of the BCL 304i to -35°C
• Supply voltage 24VDC ±20%
•BCL304i enabling through an internal temperature switch (switch-on delay about 30min for 24VDC and minimum ambient temperature of -35°C)
•Necessary conductor cross-section for the voltage supply: at least 0.75mm²; the use of ready-made cab
Construction
The heating consists of two parts:
• The front cover heater
• The housing heater
Function
When the 24VDC supply voltage is applied to the BCL 304i, a temperature switch initially only connects the heating to current (front cover heater and housing heater). During the heating phase (around 30min), when the inside temperature rises above 15°C, the temper-
ature switch connects the BCL 304i to the supply voltage. This is followed by the self test and the changeover to read operation. The "PWR" LED lights
for operation. When the inside temperature reaches approximately 18 °C, another temperature switch
turns the housing heater off and, if necessary, back on again (if the inside temperature drops below 15°C). This does not interrupt the read operation. The front cover heater remains acti­vated until an inside temperature of 25 °C is reached. At tempera cover heater switches off and, with a switching hysteresis of 3°C, back on again at an inside temperature below 22°C.

Mounting location
Notice!
The mounting location is to be selected such that it does not expose the BCL 304i with heat­ing directly to a cold air stream. To achieve an optimal heating effect, the BCL 304i should be mounted so that it is thermally isolated.
Electrical connection
The required core cross section of the connection cable for the voltage supply must be at least 0.75 mm².
44 BCL 304i Leuze electronic
Attention!
The voltage supply must not be looped through from one device to the next.
Power consumption
The energy requirement depends on the model:
• the line/raster scanner with heating typically consumes a maximum of 17W power.
• the line scanner with oscillating mirror and heating typically consumes a maximum of 26W power.
• the line/raster scanner with deflection mirror and heating typically consumes a maximum of 19W power.

5.4.1 Bar code characteristics
Notice!
Please note that the size of the bar code module influences the maximum reading distance and the width of the reading field. Therefore, when selecting a mounting location and/or the bar code label, take into account the different reading characteristics of the scanner with var­ious bar code modules.
Figure 5.6: The most important characteristics of a bar code
The range in which the bar code can be read by the BCL 304i (the so-called reading field) depends on the quality of the printed bar code and its dimensions.
Therefore, above all, the module of a bar code is decisive for the size of the reading field.
Notice!
A rule of thumb: The smaller the module of the bar code is, the smaller the maximum reading distance and reading field width will be.

6.3 Device arrangement
6.3.1 Selecting a mounting location
In order to select the right mounting location, several factors must be considered:
• Size, orientation, and position tolerance of the bar codes on the objects to be scanned.
• The reading field of the BCL 304i in relation to the bar code module width.
• The resulting minimum and maximum reading distance from the respective reading field (see chapter 5.4 "Reading field curves / optical data").
• The permissib on which interface is used.
• The correct time for data output. The BCL 304i should be positioned in such a way that, taking into consideration the time required for data processing and the conveyor belt speed, there is sufficient time to e.g. initiate sorting operations on the basis of the read data.
• The dis
• For configuring and commissioning with the webConfig tool, the USB interface should be easily accessible.
For specific information, please refer to chapter 6 and chapter 7.
Notice!
The beam of the BCL 304i exits:
• parallel to the housing base in the case of the line scanner
• at 105 degrees from the housing base
• perpendicular to the housing base in the case of the oscillating mirror
In each case, the housing base is the black area in figure 6.2. The best read results are obtained when:
• The BCL 304i is mounted in such a way that the scanning beam is incident on the bar code at an angle of inclination greater than ±10° … 15° to vertical.
• The reading distance lies in the middle area of the reading field.
• The bar code labels are of good print quality and have good contrast ratios.
• You do not use high-gloss labels.
• There is no direct sunlight.
le cable lengths between the BCL 304i and the host system depending
play elements such as LEDs or the display should be highly visible.

Zero position
The bar code label must be positioned at an angle of inclination greater than ±10° … 15° from vertical in order to avoid total reflection of the laser beam (see figure 6.6)!
Total reflection occurs whenever the laser light of the bar code reader is directly incident on the surface of the bar code at an angle of 90°. The light directly reflected by the bar code may overload the bar code reader and thereby cause non-readings!
Installation and mounting

6.3.3 Avoiding total reflection – deflection mirror scanner
For the BCL 304i with deflection mirror, the laser beam exits at an angle of 105° to the rear housing wall.
An angle of incidence of 15° of the laser to the label has already been integrated in the deflection mirror so that the BCL 304i can be installed parallel to the bar code (rear housing wall).

The BCL 304i should be mounted in such a way that the scan- ning beam is incident on the bar code at an angle of inclination greater than ±25° to vertical.
6.3.4 Avoiding total reflection – oscillating-mirror scanner
For the BCL 304i with oscillating mirror, the laser beam exits at an angle of 90° to vertical.
For the BCL 304i with oscillating mirror, the swivel range of ±20° (±12° for devices with heating) is to be taken into account.
This means that in order to be on the safe side and to avoid total reflection, the BCL 304i with oscillating mirror must be inclined upward or downward 20° … 30°!
Notice!
Mount the BCL 304i with oscillating mirror in such a way that the outlet window of the bar code reader is parallel to the object. This will result in an angle of inclination of approx. 25°.
Figure 6.8:Total reflection – BCL 304i with oscillating mirror
6.3.5 Mounting location
ª When selecting a mounting location, pay attention to:
• Maintaining the required environmental conditions (temperature, humidity).
• Possible soiling of the reading window due to liquids, abrasion by boxes, or packaging material residues.
• Lowest possible chance of damage to the BCL 304i by mechanical collision or jammed parts.
• Possible extraneous light (no direct sunlight or sunlight reflected by the bar code).

6.3.6 Devices with integrated heating
ª For devices with integrated heating, also observe the following points:
•Mount the BCL 304i in a way which provides maximum thermal isolation, e.g. using rubber-bonded metal.
•Mount in such a way that the device is protected from draft and wind; mount additional shields if necessary.
Notice!
When installing the BCL 304i in a protective housing, it must be ensured that the scanning beam can exit the protective housing without obstruction.
6.3.7 Possible reading angles between BCL 304i and bar code.
The optimum alignment of the BCL 304i is accomplished when the scan line scans the code bars almost at a right angle (90°). All reading angles that are possible between the scan line and bar code must be taken account (figure 6.9).

10.1 General information on the PROFIBUS implementation of the
BCL 304i
10.1.1 Communication profile
The communication profile defines how participants serially transmit their data via the transmission medium. The BCL 304i supports the communication profile for automation systems and Decentral Periphery -> PROFIBUS DP.
DP communication profile
The PROFIBUS DP communication profile is designed for efficient data exchange on the field level. Data exchange with the decentral devices occurs primarily cyclically. The neces-
sary communication functions are defined in the DP base functions. The DP optionally offers acyclic communication services as well. These are used for configuring, operating,
observing and alarm handling. In order to be
differentiates between on the basis of the data access points transmitted in the telegram header.
The BCL 304i profile is based on the PROFIBUS profile for identification systems.
able to perform data exchange, services are defined which PROFIBUS DP
10.1.2 Bus-access protocol
The PROFIBUS communication profiles (DP,FMS) use a uniform bus-access process. It is implemented by layer 2 of the OSI model. The bus-access control (MAC) defines the process for specifying the point in time at which a network device can transmit data. It must ensure that no more than one participant has permission to transmit at any given time. The PROFIBUS bus-access process includes the token-pass process.
Process Description BCL 304i
With this process, the bus-access permission is distributed by means of a token. The participant obtains permission to
Token-passing process

transmit with the token. The token wanders between the master devices in the ring in a permanently defined time frame. This type of bus access is used for communication between the masters. Various slave devices are assigned to a master. The master can address the slaves which are assigned to it and fetch messages from them. The master always has the initiative.
ing process and the master-slave
No
Ye s
TNT 35/7-24V
Commissioning and configuration
The two processes can also be mixed in order to create a multi-master system. The BCL 304i functions both in a mono-master system as well as in a multi-master system.
Notice!
In 2007, the PROFIBUS DP was extended by the DPV2 specification. The specification will then also permit slave-slave communication. The BCL 304i does not support this type of communication.
10.1.3 Device types
With the PROFIBUS DP, there are two types of master and one type of slave:
Device type Description BCL 304i
Class 1 master (DPM1)
Class 2 Master (DPM2)
Slave
Table 10.2: PROFIBUS DP master and slave types
Notice!
The device is defined as a slave in the device master file (GSD file) of the BCL 304i!
10.1.4 Expanded DP functions
The PROFIBUS standard has been expanded (DPV1) and, in addition to the cyclic services, also offers acyclic services. These services operate in parallel with the cyclic user-data communication. Masters and slaves can use additional READ and WRITE functions as well as ALARM functions. This is intended especially for operation with
master class 2, DPM2) in order to change parameters and read out status information during normal operation.
The acyclic services operate with lower priority. The functions are different for the various master classes.
Class 1 masters are defined for the user-data communication. (e.g.PLC,PC) Class 2 masters are defined for commissioning purposes. Additional services facilitate easier configuration as well as device diagnosis. The slave is a peripheral device which makes ava data for the control and receives output data from the control.

10.4 Commissioning via the PROFIBUS
10.4.1 General information
The BCL 304i is designed as a PROFIBUS slave device. The functionality of the device is defined via parameter sets which are clustered in modules. The modules are included in a GSD file, which is supplied as an integral part of the device. By using a user-specific config- uration 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.
Notice!
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.
10.4.2 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.

10.4.3 General information on the GSD file
You can find the GSD file at www.leuze.com -> Download -> identify -> Stationary and hand-held bar code readers.
All data in modules required for operating the BCL 304i is described in this file. These are input and output data and device parameters for the functioning of the BCL 304i and the definition of the control and status bits.
If parameters are changed, e.g., in the project tool, these changes a side in the project, not in the GSD file. The GSD file is a certified and integral part of the device and must not be changed manually. The file is not changed by the system either.
The functionality of the BCL 304i is defined via GSD parameter sets. The parameters and their functions are structured in the GSD file using module. A user-specific configuration tool is
used during PLC program creation to integrate the required modules and configure them
appropriately for their respective use. During operation of the BCL 304i on the PROFIBUS, all parameters are set to default values. If these parameters are not changed by the user,
the device functions with the default settings delivered by Leuze electronic. For the default settings of the BCL 304i, please refer to the following mod
Notice!
Please note that the set data is overwritten by the PLC! Some controls make available a so-called "universal module". This module must not be activated for the BCL 304i!
From the perspective of the device, a distinction is made between PROFIBUS parameters and internal parameters. PROFIBUS parameters are all parameters that can be changed via
the PROFIBUS and are described in the following modules. Internal parameters, on the other hand, can only b a PROFIBUS configuration.
During the configuration phase, the BCL receives a parameter telegram from the master. Before this is evaluated and the respective parameter values are set, all PROFIBUS parameters are reset to default values. This ensure not selected are set to the default values.
Notice!
This does not affect modules 1-4 for the code table extension. By default, all but the first code table entry are locked. If "no code" is selected here, all subsequent code tables are deactivated (see chapter 10.6.1 "Modules 1-4 – Code table extensions 1 to 4").

10.4.4 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 configuration tool.
These parameters must always be present. They are defined outside of the modules and are perm
Simatic S7 Controller
In Simatic Manager, the permanently defined parameters are set via object properties of the device. The module parameters are set via the module list of the selected device. By selecting the project properties of a module, the respective parameters may be set if required.
The following list contains the parameters that are permanently defined in the BCL 304i but are config modules.

10.5 Overview of the project modules
In the current version, a total of 52 modules are available for use. A Device Module (see "Permanently defined parameters / device parameters" on page 94) is used for basic scanner configuration BCL 304i and is permanently integrated into the project. Further modules may be included into the project according to requirements and application.
The modules
•Parameter module for the configuration of the BCL 304i
• Status or control modules that influence the input/output data.
•Modules that may include both parameters and control or status information.
A PROFIBUS module defines the existence and meaning of the input and output data. In
ddition, it defines the necessary parameters. The arrangement of the data within a module
a
is defined. The composition of the input/output data is defined via the module list. The BCL 304i interprets the incoming output data and triggers the appropriate reactions in
the BCL 304i. The interpreter for processing the data is adapted to the module structure du
ring initialization.
The same applies for the input data. Using the module list and the defined module proper­ties, the input data string is formatted and referenced to the internal data.
During cyclic operation, the input data is then passed on to the master.
fall into the following categories:
Notice!
The modules can be grouped together in any order in the engineering tool. The BCL 304i offers 52 different modules. Each of these modules may only be selected once; otherwise, the BCL 304i ignores the configuration. The BCL 304i checks its max. permissible number of modules. In addition, it checks the max. permissible total length (244 bytes each) of the input and output data over all selected modules. The specific limits of the individual modules of the BCL 304i are declared in the GSD file.
