Fast commissioning / operating principle
3Fast commissioning / operating principle
Below you will find a short description for the initial commissioning of the BCL 338i. Detailed
explanations for all listed points can be found throughout this technical description.
3.1Mounting the BCL 338i
The BCL 338i bar code readers can be mounted in two different ways:
• Via four M4x6 screws on the device bottom.
• Via a BT 56 mounting device in the fastening groove on the housing bottom.
3.2Device 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 338i 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 338i and the host system depending
on which interface is used.
• The correct time for data output. The BCL 338i 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 visible and accessible.
• 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.
Note!
The beam exits the BCL 338i as follows for the respective devices:
- line scanner parallel to the housing base
- deflecting 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 338i 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.

3.4BCL 338i on the EtherCAT
3.4.1Device description file
For EtherCAT, all process data and parameters are described in objects. The compilation
of all process data and parameters of the BCL 338i - the object directory - is stored in a socalled ESI file (EtherCAT Slave Information).
The ESI file contains all objects with index, sub-index, name, data type, default value,
minimum and maximum, and access possibilities. That means the ESI file describes the
entire functionality of the BCL 338i.
The ESI file has the name BCL338i.xml and is available for download on the Leuze home
page.
Vendor ID for the BCL 338i
The Vendor ID assigned by Leuze electronic for the BCL 338i is 121h = 289d.
Detailed information on the device description file and the object directory can be
found in Chapter 10.
3.4.2Device profile
The object designations and groupings of the generic device profile of the BCL 338i are
based on common bar code reader profiles.
Detailed information can be found in Chapter 11.4.
3.4.3Starting the BCL 338i in the EtherCAT system
As is common for EtherCAT, the BCL 338i runs through different states when starting up:
"INIT", "PREOP", "SAFEOP" and "OPERATIONAL".
Detailed information can be found in Chapter 11.
22BCL 338iLeuze electronic
Page 25
3.5Further settings
Note!
With the BCL 338i, the configuration of the device functionality is generally performed via
the webConfig tool (see Chapter 9). EtherCAT is only used to set the bus-specific parameters for communication.
A special option for device configuration via EtherCAT is the transfer of "PT sequences". Information on this topic is only available on request.
After the basic configuration of the operating mode and the communication parameters, you
need to carry out further settings:
• Decoding and processing the read data
Define at least one code type with the desired settings.
• Via webConfig:

If Reading Result is displayed, the device is ready.
Operation of BCL 338i
After voltage (18 … 30VDC) has been connected to the switching input, a read process is
activated. In the standard setting, all common code types for decoding are released; only
the 2/5 Interleaved code type is limited to 10 digits of code content.
If a code is moved through the reading field, the code content is decoded and forwarded to
the superior system (controller) via EtherCAT.

Provided your BCL 338i model has a display, the read information appears on this display.
The PWR LED goes off briefly and then turns green again. Simultaneously, the read information is forwarded to the superior system (PLC/PC) via the Ethernet.
Please check the incoming data of the bar code information there.
Alternatively, you can use a switching input for read activation (switching signal of a photo-
electric sensor or 24VDC switching signal).

4.1About the bar code readers of the BCL 300i series
Bar code readers of the BCL 300i series are high-speed scanners with integrated decoder
for all commonly used bar codes, e.g. 2/5 Interleaved, Code 39, Code 128, EAN 8/13 etc.,
as well as codes from the GS1 DataBar family.
Bar code readers of the BCL 300i series are available in various optics models as well as
line scanners, line scanners with deflecting mirrors and oscillating mirrors and also optionally as heated models.
Device description
Figure 4.1:Line scanner, line scanner with deflecting mirror and oscillating-mirror scanner
The many possible configurations of the device allow it to be adapted to a multitude of
reading tasks. Due to the large reading distance combined with the great depth of field, a
large opening angle and a very compact construction, the device is ideally suited for the
conveyor and storage technology market.
The interfaces (RS 232, RS 485 and RS 422) integrated in the various device models and
the fieldbus systems (PROFIBUS DP, PROFINET-IO, Ethernet TCP/IP UDP, EtherNet/IP
and EtherCAT) offer optimum connection to the superior host system.

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 connection 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 additional software.
For decoding bar codes, the bar code readers of the BCL 300i series make available the
proven CRT decoder with code reconstruction technology:
The proven code reconstruction 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.
28BCL 338iLeuze electronic
Page 31
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
The BCL 338i can be operated and configured using the integrated webConfig tool via the
USB service interface; alternatively, the bar code readers can be adjusted using configuration commands via the host/service interface.
The BCL 338i needs a suitable activation to start a read process as soon as an object is in
the reading field. This opens a time window ("reading gate") in the BCL 338i for the read
process during which the bar code reader has time to detect and decode a bar code.
In the basic setting, triggering takes place through an external reading cycle signal. Alternative activation options include online commands via the host interface and the autoReflAct
function.
Through the read operation, the BCL 338i collects additional useful pieces of data for
diagnostics 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.
An optional, multi-language display with buttons is used to operate the BCL 338i as well as
for visualization purposes. Two LEDs provide additional optical information on the current
operating state of the device.
The two freely configurable switching inputs/outputs SWIO1 and SWIO2 can be assigned
various functions and control e.g. activation of the BCL 338i or external devices, such as a
PLC.
System, warning and error messages provide assistance in setup/troubleshooting during
commissioning and read operation.

4.4Reading techniques
4.4.1Line 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 reconstruction 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
4.4.2Line 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 338i 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 reading distance due to the optical opening angle of
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 objects.
• when a large reading field (reading window) has to be covered.

34BCL 338iLeuze electronic
Page 37
4.4.3Raster scanner (raster line)
Multiple scan lines scan the label. Due to the optical opening angle, the reading field width
is dependent on the read 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 reconstruction 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. 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

4.5Fieldbus systems
Various product variants of the BCL 300i series are available for connecting to different
fieldbus systems such as PROFIBUS DP, PROFINET, Ethernet, EtherNet/IP and EtherCAT.
4.5.1EtherCAT
General information on EtherCAT
EtherCAT is an Ethernet-based fieldbus initiated by the Beckhoff corporation. The EtherCAT
Technology Group (ETG) is the official standardization partner of the IEC working groups.
EtherCAT has been an IEC standard since 2005.
• IEC 61158: Protocols and services
• IEC 61784-2: Communication profiles for the specific device classes
All EtherCAT-specific communication mechanisms are described in detail in the standards
mentioned above. This technical description will describe parts of the IEC standard if this
assists general understanding.
EtherCAT topology
EtherCAT permits a multitude of topologies such as line, tree, ring, star and combinations
of these. The bus or line structure known from the fieldbuses is thus also available for
EtherCAT.
Telegrams are sent on a wire pair in the "processing direction" from the master to the slave.
The EtherCAT device processes the frames only in this direction and passes them on to the
subsequent device until the telegram has passed through all devices. The last device sends
the telegram back to the master on the second wire pair of the bus cable in the "forward
direction". Here, the EtherCAT always forms a logical ring structure regardless of the topology installed.
From an Ethernet point of view, an EtherCAT bus segment is nothing more than a single,
large Ethernet participant which sends and receives Ethernet telegrams. Within the "participant", however, there is a multitude of EtherCAT slaves rather than one single Ethernet
controller.

4.6Heating
For low-temperature applications to min. -35°C (e.g. in cold storage), the bar code readers
of the BCL 338i series can optionally be permanently fitted with a built-in heating and these
bar code readers purchased as separate device models.
4.7autoReflAct
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.
Note!
Compatible reflectors are available on request.
As long as the scanner is targeted at the reflector, the reading 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.
Device description
Figure 4.13: Reflector arrangement for autoReflAct
The autoReflAct function uses the scanning beam to simulate a photoelectric sensor and
thus permits an activation without additional sensors.

Device description
4.8Reference codes
The BCL 338i offers the possibility of storing one or two reference codes.
It is possible to store the reference codes via the webConfig tool or via online commands.
The BCL 338i can compare read bar codes with one and/or both reference codes and
execute user-configurable functions depending on the comparison result.
4.9autoConfig
With the autoConfig function, the BCL 338i offers an extremely simple and convenient configuration option to users who only want to read one code type (symbology) with one number
of digits at a time.
After starting the autoConfig function via the switching input or from a superior control, it is
sufficient to position a bar code label with the desired code type and number of digits in the
reading field of the BCL 338i.
Afterward, bar codes with the same code type and number of digits are recognized and
decoded.

5.2Heating models of the bar code readers
The BCL 338i 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 338i to -35 °C
• Supply voltage 18 … 30V DC
• Enabling the BCL 338i through an internal temperature switch
(switch-on delay about 30 min for 24 V DC and minimum ambient temperature of
-35 °C)
• Necessary conductor cross-section for the voltage supply: at least 0.75 mm²; the use
of ready-made cables is, thus, not possible
Structure
The heating consists of two parts:
• The front cover heater
• The housing heater
Function
When the 24 V DC supply voltage is applied to the BCL 338i, a temperature switch initially
only connects the heating to electrical power (front cover heater and housing heater). During
the heating phase (around 30 min), when the inside temperature rises above 15 °C, the
temperature switch connects the BCL 338i to the supply voltage. This is followed by the self
test and the changeover to read operation. The PWR LED lights up, showing overall readiness for operation.
When the inside temperature reaches approx. 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 temperatures above this, the front cover
heater switches off and, with a switching hysteresis of 3 °C, back on again at an inside
temperature below 22 °C.
Mounting location
Note!
The mounting location is to be selected such that the it does not expose the BCL 338i with
heating directly to a cold air stream. To achieve an optimal heating effect, the BCL 338i
should be mounted so that it is thermally isolated.
Electrical connection
The required wire cross section of the connection cable for the voltage supply must be at
least 0.75 mm².
42BCL 338iLeuze electronic
Page 45
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 consumes a maximum of 27W power.
• the line scanner with oscillating mirror and heating consumes a maximum of 45W.
• the line/raster scanner with deflecting mirror and heating consumes a maximum of
27W power.
These values are based on operation with unconnected switching outputs.

5.4.1Bar code characteristics
Note!
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 5.7:The most important characteristics of a bar code
The range in which the bar code can be read by the BCL 338i (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.
Technical data
Note!
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.

6.3Device arrangement
6.3.1Selecting 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 338i 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 permissible cable lengths between the BCL 338i and the host system depending
on which interface is used.
• The correct time for data output. The BCL 338i 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 elements such as LEDs or the display should be highly visible.
• For configuring and commissioning with the webConfig tool, the USB interface should
be easily accessible.
For specific information, please refer to Chapter 6.
Note!
The beam of the BCL 338i exits:
• Parallel to the housing base in the case of the line scanner
•At 105 degrees from the housing base in the case of the deflecting mirror
• 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 338i 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.

6.3.2Avoiding total reflection – Line scanner
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 6.7)!
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!
Figure 6.7:Total reflection – line scanner
6.3.3Avoiding total reflection – deflecting mirror scanner
For the BCL 338i with deflecting 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
deflecting mirror so that the BCL 338i can be installed parallel to the bar code (rear housing
wall).

The BCL 338i should be mounted in such a way that the scanning beam is incident on the bar code at an angle of inclination
greater than ±25° to vertical.
6.3.4Avoiding total reflection – oscillating-mirror scanner
For the BCL 338i with oscillating mirror, the laser beam exits at an angle of 90° to
vertical.
For the BCL 338i 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 338i
with oscillating mirror must be inclined upward or downward 20° … 30°!
Note!
Mount the BCL 338i with oscillating mirror in such a way that the exit window of the bar code
reader is parallel to the object. This will result in an angle of inclination of approx. 25°.
Figure 6.9:Total reflection – BCL 338i with oscillating-mirror scanner
6.3.5Mounting location
When choosing the mounting location, observe the following:
• 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 338i by mechanical collision or
jammed parts.
• Possible extraneous light (no direct sunlight or sunlight reflected by the bar code).

6.3.6Devices with integrated heating
When mounting devices with integrated heating, also observe the following points:
• Mount the BCL 338i 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.
Note!
When installing the BCL 338i in a protective housing, it must be ensured that the scanning
beam can exit the protective housing without obstruction.
6.3.7Possible read angles between BCL 338i and bar code
The optimum alignment of the BCL 338i is accomplished when the scan line scans the bar
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 6.10).
In order to avoid total reflection, the skew should be greater than 10°

Attention!
For UL applications, use is only permitted in Class 2 circuits in accordance with the NEC
(National Electric Code).
The bar code readers of the BCL 300i … series are designed in accordance with protection
class III for supply by PELV (protective extra-low voltage with reliable disconnection).
Connecting the functional earth FE
Ensure that the functional earth (FE) is connected correctly. Unimpaired operation is only
guaranteed when the functional earth is connected properly. All electrical disturbances
(EMC couplings) are discharged via the functional earth connection.

Switching input/output
The bar code readers of the BCL 300i series are equipped with two freely programmable,
opto-decoupled switching inputs and outputs, SWIO_1 and SWIO_2.
The switching inputs can be used to activate various internal functions of the BCL 338i
(decoding, autoConfig, …). The switching outputs can be used to signal the state of the
BCL 338i and to implement external functions independent of the superior control.
Note!
The respective function as input or output can be set with the aid of the
webConfig configuration tool!
Described in the following is the external wiring for use as a switching input or output; the
respective function assignments to the switching inputs/outputs can be found in Chapter 10.
Function as switching input
Figure 7.1:Switching input connection diagram SWIO_1 and SWIO_2
If you use a sensor with a standard M12 connector, please note the following:
• Pins 2 and 4 must not be operated as switching outputs if sensors which function as
inputs are also connected to these pins.
If, for example, the inverted sensor output is connected to pin 2, and pin 2 of the bar code
reader is, at the same time, configured as an output (and not as an input), the switching
output malfunctions.
Each configured switching output is short-circuit proof! Do not load the respective switching
output of the BCL 338i with more than 60mA at +18 … +30VDC in normal operation!
Note!
Both switching inputs/outputs SWIO_1 and SWIO_2 are configured by default in such a way
that:
• Switching input SWIO_1 activates the reading gate.
• Switching output SWIO_2 switches by default on "No Read."
7.3.2SENSOR - direct connection of an external sensor (ME 338 xx4 only)
Connection hoods ME 338 104 and ME 338 214 are equipped with an M8 connection cable

7.3.5BUS OUT for the BCL 338i
To set up an EtherCAT network with other participants with linear topology, the BCL 338i
makes available another Ethernet interface. The use of this interface drastically reduces the
cabling requirements, as only the first BCL 338i requires a direct connection to the switch,
via which it can communicate with the host. All other BCL 338i are connected in series to
the first BCL 338i, see Figure 7.3.

For the BCL 338i as stand-alone device or as the last participant in a linear topology, termination on the BUS OUT socket is not mandatory!
7.4EtherCAT topologies
EtherCAT permits a multitude of topologies such as line, tree, ring, star and combinations
of these. The bus or line structure known from the fieldbuses is thus also available for
EtherCAT.
Telegrams are sent on a wire pair in the "processing direction" from the master to the slave.
The EtherCAT device processes the frames only in this direction and passes them on to the
subsequent device until the telegram has passed through all devices. The last device sends
the telegram back to the master on the second wire pair of the bus cable in the "forward
direction". Here, the EtherCAT always forms a logical ring structure regardless of the topology installed.
From an Ethernet point of view, an EtherCAT bus segment is nothing more than a single,
large Ethernet participant which sends and receives Ethernet telegrams. Within the "participant", however, there is a multitude of EtherCAT slaves rather than one single Ethernet
controller.

Electrical connection
Each participating BCL 338i is automatically assigned its address by a DHCP server. Alternatively, each BCL 338i can be assigned the respective network address via the
webConfig tool.
Information on the necessary configuration steps can be found in Chapter 10 and
Chapter 11.
7.4.1EtherCAT wiring
A Cat. 5 Ethernet cable should be used for wiring.
Connection hood "ME 338 214" is available for the direct connection to the BCL 338i. It is
equipped with 2 connection cables with RJ45 socket into which the standard network cables
can be plugged.
If no standard network cables are to be used (e.g. due to lacking IP… degree of protection),
you can use the "KS ET-M12-4A-P7-…" user-configurable cables on the BCL 338i (depending on the connection hood used), see Table 14.9 "Bus connection cables for the
BCL 338i" on page 180.
The connection between the individual BCL 338i devices in a linear topology with M12
connection technology is performed with the "KSS ET-M12-4A-M12-4A-P7-…" cables, see
Table 14.9 "Bus connection cables for the BCL 338i" on page 180.
For unavailable cable lengths, you can configure your cable yourself. When doing so, make
certain that you connect TDx+ on the M12 connector with RD+ on the RJ-45 connector and
TDx- on the M12 connector with RD- on the RJ-45 connector, respectively, etc.
Note!
Use the recommended plugs / sockets or the ready-made cables (see chapter 14 "Type
overview and accessories").
