Fast commissioning
Leuze electronic GmbH + Co. KG BCL 248i 11
3 Fast commissioning
Below you will find a short description for the initial commissioning of the BCL248i. 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/PROFINET, 4-pin, D-coded, cable length 0.7m (shielded)

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 need to assign its individual device name to the BCL248i. The PLC must communicate this de-
vice name to the participant during the "device naming". Further information may be found below and in
see chapter 8.3.5 "Step 5 – Set device name – device naming".
3.4.1 Commissioning the BCL 248i on the PROFINET-IO
ÄComplete the necessary steps for commissioning a Siemens-S7 control as described below.
Further information regarding the individual commissioning steps is provided in see chapter 8.3 "Configura-
tion steps for a Siemens SimaticS7 control".
3.4.2 Prepare the control
ÄIn the first step, assign an IP address to the IO controller (S7 PLC) and prepare the control for a consis-
tent data transmission.
NOTICE
ÄWith the S7 control, make sure that at least Simatic Manager Version5.4 + Service Pack5
(V5.4+SP5) is used.

Fast commissioning
Leuze electronic GmbH + Co. KG BCL 248i 13
3.4.3 Installing GSD file
For the subsequent configuration of the IOdevices, e.g., BCL248i, the corresponding GSD file must be
loaded first. In this file, all data necessary for operating the BCL248i is described in modules. These are in-
put and output data and device parameters for the functioning of the BCL248i and the definition of the con-
trol and status bits.
ÄInstall the GSD file associated with the BCL248i in the PROFINET-IO Manager of your control.
3.4.4 Configuration
ÄConfigure the PROFINET-IO system with the HW Config of the SIMATIC Manager by inserting the
BCL248i into your project.
ðHere, an IP address is assigned to a unique "device name".
Fig.3.2: Assignment of the device names to IP addresses
3.4.5 Transmit the configuration to the IO controller
ÄTransmit the PROFINET-IO configuration to the IO controller (S7 PLC).
After correct transmission to the IO controller (S7 PLC), the PLC automatically carries out the following ac-
tivities:
• Check of device names
• Assignment of the IP addresses that were configured in the HW Config to the IOdevices
• Establishment of a connection between the IOController and configured IOdevices
• Cyclical data exchange
NOTICE
Participants that have not been "named" cannot be contacted yet at this point in time.

Fast commissioning
Leuze electronic GmbH + Co. KG BCL 248i 14
3.4.6 Setting the device name – device naming
PROFINET-IO defines the "naming of the device" as the creation of a name-based relationship for a
PROFINET-IO device.
Assigning the device name to the configured IO devices
ÄSelect the respective BCL248i bar code reader for the "device naming" based on its MAC address.
ðThis participant is assigned the unique "device name." This must match the device name in the HW
config and must not be longer than 255 characters.
Fig.3.3: Assigning the device names to the configured IOdevices
NOTICE
Multiple BCL248i can be distinguished by the MAC addresses displayed. The MAC address
may be found on the name plate of the respective bar code reader.
Assignment of MAC address – IP address – individual device name
ÄAssign an IP address (suggested by the PLC), a subnet mask and, if required, a router address, and
assign this data to the named participant ("device name").
ðFrom now on, and when programming, only the unique "device name" is used.

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 PROFINET-IO.

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 PROFINET-IO.
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).

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
With the BCL248i, configuration is generally performed with the aid of the GSD file.
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 or via PROFINETIO.
An alternative option for activation is 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.
