Fast commissioning
Leuze electronic GmbH + Co. KG BCL 208i 9
3 Fast commissioning
Below you will find a short description for the initial commissioning of the BCL208i. Detailed explanations
for all listed points can be found throughout these operating instructions.
3.1 Mounting
The bar code reader can be mounted in the following ways:
• Mounting with four M4x5 screws on the rear side of the housing.
• Mounting with mounting devices on the fastening groove on one side of the housing.
3.2 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 bar code reader in relation to the bar code module width.
• The resulting minimum and maximum reading distance from the respective reading field with the re-
spective module width (see chapter 13.2 "Reading fields").
• alignment of the bar code reader for avoiding reflections.
• Distance between bar code reader and host system with respect to the interface.
• The correct time for data output. The bar code reader 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 should be highly visible.
• For configuring and commissioning with the webConfig tool, the HOST interface should be easily ac-
cessible.
For further information, see see chapter 5 "Mounting" and see chapter 6 "Electrical connection".
The best read results are obtained if the following prerequisites are fulfilled:
• The reading distance lies in the middle area of the reading field.
• There is no direct sunlight and protect against ambient light effects.
• The bar code labels are of good print quality and have good contrast ratios.
• You are not using high-glossy labels.
• The bar code is moved past with an angle of inclination of ±10°…15° to vertical.
NOTICE
Avoid direct reflection of the laser beam!
The beam on the bar code reader is emitted at 105° to the housing base. An angle of incidence
of 15° of the laser to the label has already been integrated in the deflecting mirror so that the bar
code reader can be installed parallel to the bar code (rear housing wall).
3.3 Electrical connection
The bar code reader is equipped with two connection cables, each with an M12 connector.
• PWR/SWIO: M12 connection for supply voltage and switching input/output, 5-pin, A-coded, cable
length 0.9m (unshielded)
• HOST: M12 connection for Ethernet, 4-pin, D-coded, cable length 0.7m (shielded)

NOTICE
The shielding is connected using the M12 connector of the Ethernet cable.
Details on the connectors see chapter 6 "Electrical connection".
3.4 Preparatory settings
ÄConnect the +18…30 VDC supply voltage (typically +24VDC).
ðThe bar code reader starts up.
First, you must now set the communication parameters of the BCL208i. Make the necessary settings via
the webConfig tool, see chapter 8 "Starting up the device - Configuration".
3.4.1 Manually setting the IP address
Set the IP manually if your system does not include a DHCP server or if the IP addresses of the devices
are to be set permanently.
ÄHave the network administrator specify the data for IP address, net mask and gateway address of the
BCL208i.
ÄSet the values on the BCL208i.
In the webConfig tool:
Configuration > Communication > Ethernet interface
NOTICE
ÄAfter making the setting via the webConfig tool, restart the BCL208i.
ðThe set IP address is only accepted and active after a restart.

Fast commissioning
Leuze electronic GmbH + Co. KG BCL 208i 11
3.4.2 Automatically setting the IP address
Set the IP address automatically if a DHCP server assigns the IP addresses in the system.
ÄActivate the DHCP Client mode in the BCL208i.
In the webConfig tool:
Configuration > Communication > Ethernet interface
ÄActivate the DHCP=ON setting there.
3.4.3 Ethernet host communication
You can configure the connections to an external host system via the Ethernet host communication.
You can use both the UDP protocol as well as the TCP/IP protocol – in either client or in server mode. Both
protocols can be activated simultaneously and used in parallel.
• The connection-free UDP protocol is used primarily to transfer process data to the host (monitor opera-
tion).
• The connection-oriented TCP/IP protocol can also be used to transfer commands from the host to the
device. With this connection, the data is backed up by the TCP/IP protocol itself.
• If you would like to use the TCP/IP protocol, you must also define whether the device is to operate as a
TCP client or as a TCP server.
UDP
The device requires from the user the IP address and the port number of the communication partner. In the
same way, the host system (PC/control) also requires the set IP address of the device and the selected
port number. By assigning these parameters, a socket is formed via which the data can be sent and re-
ceived.
ÄActivate the UDP protocol.
ÄSet the following values:
ðIP address of the communication partner
ðPort number of the communication partner
The corresponding adjustment options can be found in the webConfig tool:
Configuration > Control > Host > Ethernet > UDP
TCP/IP
ÄActivate the TCP/IP protocol.
ÄSet the TCP/IP mode of the device.
ðIn TCP client mode, the device actively establishes the connection to the superior host system, e.g.,
PC/control as server. The device requires from the user the IP address of the server (host system)
and the port number on which the server (host system) accepts a connection. In this case, the de-
vice determines when and with whom a connection is established.
ðIn TCP server mode, the superior host system (PC/control) actively establishes the connection and
the connected device waits for the connection to be set up.
The TCP/IP stack must be informed by the user as to the local port of the device (port number) on
which connection requests from a client application (host system) are to be received.
If there is a connection request and a connection is established by the superior host system (PC/
control as client), the device – in server mode – accepts the connection. Data can then be sent and
received.
ÄWith a device as TCP client, set the following values:
ðIP address of the TCP server, normally the IP address of the control or the host computer
ðPort number of the TCP server
ðTimeout for the wait time for an answer from the server
ðRepetition time for renewed communication attempt following a timeout
ÄWith a device as TCP server, set the following values:
ðPort number for the communication of the device with the TCP clients
The corresponding adjustment options can be found in the webConfig tool:
Configuration > Control > Host > Ethernet > TCP/IP

Operating the bar code reader
After connecting a supply voltage of +18…30VDC 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 (PLC/PC) via Ethernet.
3.7 Bar code reading
ÄTest the device with the following bar code in format 2/5 Interleaved. The bar code module here is 0.5.
Modul 0,5

The PWR LED goes off briefly and then turns green again. Simultaneously, the read information is for-
warded to the superior system (PLC/PC) via the Ethernet.
ÄCheck the incoming data of the bar code information.
Alternatively, you can use a switching input for read activation (switching signal of a photoelectric sensor or
24 V DC switching signal).

Integrated fieldbus connectivity
The integrated fieldbus connectivity contained in the bar code readers of the BCL200i series facilitates the
use of identification systems which function without connection unit or gateways. The integrated fieldbus in-
terface considerably simplifies handling. The Plug-and-Play concept enables easy networking and very
simple commissioning: Directly connect the respective fieldbus and all configuration is performed with no
additional software.
CRT decoder
For decoding bar codes, the bar code readers of the BCL200i series make available the proven CRT de-
coder with code reconstruction technology.
The proven code reconstruction technology (CRT) enables bar code readers of the BCL200i series to read
bar codes with a small bar height, as well as bar codes with a damaged or soiled print image.
With the aid of the CRT decoder, bar codes can also be read without problem in other demanding situa-
tions, such as with a large tilt angle (azimuth angle or even angle of rotation).

Fig.4.1: Possible bar code orientation
Configuration
Configuration of the BCL208i usually takes place via the HOST interface using the integrated webConfig
tool. Alternatively, the bar code readers can be configured via the host/service interface using configuration
commands.
The bar code reader needs a suitable activation to start a read process as soon as an object is in the read-
ing field. This opens a time window ("reading gate") in the bar code reader 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 bar code reader 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.

4.5 Reading techniques
4.5.1 Line scanner (single line)
The scan line scans the label. Due to the optical 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 lim-
its. These are dependent on the transport speed, the scanning rate of the scanner and the bar code proper-
ties.
Areas of application of the line scanner
• With the bars of the bar code arranged lengthwise with respect to the conveying direction ("ladder ar-
rangement")
• With bar codes having very short bar lengths
• When the ladder code is turned out of the vertical position (tilt angle)

4.5.2 Raster 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 lim-
its. These are dependent on the transport speed, the scanning rate of the scanner and the bar code proper-
ties. In most cases, everywhere a line scanner is used, a raster scanner can be used.
Areas of application of the raster scanner
• With the bars of the bar code arranged perpendicular with respect to the conveying direction ("picket
fence arrangement")
• With bar codes with low height displacement
• With very glossy bar codes
NOTICE
There may not be two or more bar codes in the raster detection range simultaneously.

4.6 Fieldbus systems
Various product variants of the BCL200i series are available for connecting to different fieldbus systems
such as PROFINET, Ethernet, and EtherNet/IP.
4.6.1 Ethernet
The BCL208i is designed as an Ethernet device (acc. to IEEE 802.3) with a standard baud rate of
10/100Mbit. On delivery, each BCL208i comes with a unique MAC-ID; this ID cannot be changed.
The BCL208i automatically supports the transmission rates of 10Mbit/s (10BaseT) and 100Mbit/s
(100BaseTX), as well as auto-negotiation and auto-crossover.

Device description
Leuze electronic GmbH + Co. KG BCL 208i 20
The BCL208i features multiple M12 connectors / sockets for the electrical connection of the supply volt-
age, the interface and the switching inputs and outputs. For further information on electrical connection,
see chapter 6 "Electrical connection".
The BCL208i supports further protocols and services for communication:
• TCP / IP (client/server)
• UDP
• DHCP
• Telnet
• HTTP
• ARP
• PING
For communication with the superior host system, the corresponding TCP/IP protocol (client/server mode)
or UDP must be selected.
Further information on commissioning: see chapter 7 "Starting up the device – Leuze webConfig tool".
4.6.2 Ethernet – star topology
The BCL208i can be operated as a single device (stand-alone) with an individual IP address in a star
topology. The IP address can either be set permanently via webConfigtool or assigned dynamically via a
DHCP server.

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
Suitable reflectors are available, see chapter 14.5 "Accessories – Reflectors and reflective
tapes".
