Fast commissioning
3 Fast commissioning
Below you will find a short description for the initial commissioning of the BCL248i. 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 respective 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 accessible.
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 0.9m (unshielded)
• HOST: M12 connection for Ethernet/PROFINET, 4-pin, D-coded, cable length 0.7m (shielded)

Device description
CRT decoder
For decoding bar codes, the bar code readers of the BCL200i series make available the proven CRT decoder with code reconstruction technology.
The proven code reconstruction technology (CRT) enables bar code readers of the BCL200i 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 situations, such as with a large tilt angle (azimuth angle or even angle of rotation).
Fig.4.1: Possible bar code orientation
Configuration
With the BCL248i, 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 reading 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 PROFINETIO.
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.

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 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
• With the bars of the bar code arranged lengthwise with respect to 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)
• No connection established
• No communication possible
Leuze electronic GmbH + Co. KG BCL 248i 22
Device description
4.5.2
Fig.4.4: Deflection principle for the line scanner
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 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
• 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.

4.7 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".
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.
Leuze electronic GmbH + Co. KG BCL 248i 26
Device description
Fig.4.7: Reflector arrangement for autoReflAct
The autoReflAct function uses the scanning beam to simulate a photoelectric sensor and thus permits an
activation without additional sensors.
4.8 Reference codes
The bar code reader offers the possibility of storing one or two reference codes.
It is possible to store the reference codes via the webConfigtool, via online commands or via PROFINETIO.
The bar code reader can compare read bar codes with one and/or both reference codes and execute userconfigurable functions depending on the comparison result.
4.9 autoConfig
With the autoConfig function, the bar code reader 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 bar code
reader.
Afterward, bar codes with the same code type and number of digits are recognized and decoded.
NOTICE
The settings made via the webConfig configuration tool only temporarily push the parameters
set in the PROFINET-IO into the background. The settings are overwritten during integration
into the PROFINET-IO or after deactivation of service mode of the PROFINET master with
those settings made via the GSD file.
Device settings for operating the BCL248i on the PROFINET-IO are managed and configured
exclusively by the PROFINET-IO controller (PLC).
Ä Make permanent changes in the PROFINET-IO controller.
For further information, see chapter 8 "Starting up the device - Configuration".

5.3 Selecting a mounting location
NOTICE
The size of the bar code module influences the maximum reading distance and the width of the
reading field.
Ä When selecting a mounting location and/or the bar code label, take into account the different
reading characteristics of the bar code reader with various bar code modules.
NOTICE
Observe when choosing the mounting location!
Ä Maintain the permissible environmental conditions (humidity, temperature).
Ä Avoid possible soiling of the reading window due to liquids, abrasion by boxes, or packaging
material residues.
Ä Ensure that there is the lowest possible chance of damage to the bar code reader by me-
chanical collision or jammed parts.
Ä Avoid possible ambient light influence (no direct sunlight).
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 respective 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 accessible.

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).
Ä Mount the bar code reader with deflecting mirror parallel to the bar code.

Mounting
Reading angle between bar code reader and bar code
The optimum alignment of the bar code reader 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.
α Azimuth angle (tilt)
β Angle of inclination (Pitch)
γ Angle of rotation (skew)
Fig.5.2: Reading angle for the line scanner
In order to avoid total reflection, the γ angle of rotation (skew) should be greater than 10°.
5.4 Cleaning
Ä Clean the glass window of the bar code reader with a soft cloth after mounting.
Ä Remove all packaging remains, e.g. carton fibers or Styrofoam balls.
Ä In doing so, avoid leaving fingerprints on the front screen of the bar code reader.

8.1 PROFINET-IO
The PROFINET-IO communication profile defines how participants serially transmit their data via the transmission medium.
The PROFINET‑IO communicationprofile is designed for efficient data exchange on the field level. Data
exchange with the devices occurs primarily cyclically. For configuration, operation, observation and alarm
handling, acyclic communication services are, however, used as well.
Depending on the communication requirements, PROFINET-IO offers suitable protocols and transfer methods:
Real Time communication (RT) via prioritized Ethernet frames for
• Cyclical process data (I/O data stored in the I/O area of the control)
• Alarms
• Clock synchronization
• Neighborhood information
• Address assignment/address resolution via DCP
TCP/UDP/IP communication via standard Ethernet TCP/UDP/IP frames for
• Establishing communication
• Acyclic data exchange, and also for the transfer of various information types such as:
• Parameters for the module configuration while communication is being established
• I&M data (Identification & Maintenance functions)
• Reading diagnostic information
• Reading I/O data
• Writing device data
8.2 Starting the device
NOTICE
Before commissioning, familiarize yourself with the operation and configuration of the BCL248i.
Before connecting the supply voltage, recheck all connections and ensure that they have been
properly made.
Ä Connect the +18…30 VDC supply voltage (typically +24VDC).
ð The BCL248i starts up, the PWR, NET and LINK LEDs indicate the operating state.
First, you need to assign its individual device name to the BCL248i.

8.3 Configuration steps for a Siemens SimaticS7 control
The following steps are necessary for commissioning with a Siemens S7 control:
1. Preparation of the control system S7 PLC
2. Installation of the GSD file
3. Hardware configuration of the S7 PLC
4. Transmission of the PROFINET-IO configuration to the IO controller (S7 PLC)
5. Device naming
• Configuration of the device name
• Device naming
• Assigning the device names to the configured IOdevices
• Assignment of MAC address – IP address – individual device names
6. Check device name
8.3.1
8.3.2
Step 1 – Prepare the control
The first step involves the assignment of an IP address to the IO controller (S7 PLC) and the preparation of
the control for consistent data transmission.
NOTICE
Ä With the S7 control, make sure that at least Simatic Manager Version5.4 + Service Pack5
(V5.4+SP5) is used.
Step 2 – Installing GSD file
For the subsequent configuration of the IOdevices, e.g., BCL248i, the corresponding GSD file must be
loaded first. In this file, all data necessary for operating the BCL248i is described in modules. These are input and output data and device parameters for the functioning of the BCL248i and the definition of the control and status bits.
GSD files
The term GSD stands for the textual description of a PROFINET-IO device model. For this purpose, the
XML-based GSDML (Generic Station Description Markup Language) was introduced. In the following, the
terms "GSD" or "GSD file" always refer to the GSDML-based format.
The GSDML file can support an arbitrary number of languages in one file. Every GSDML file contains a
version of the BCL248i device model. This is also reflected in the file name.
File name structure
The file name of the GSD file is constructed according to the following rule:
GSDML-[GSDML-schema version]-Leuze-BCL248i-[Date].xml
Explanation:
• GSDML schema version:
Version identifier of the GSDML schema version used, e.g., V2.2
• Date:
Release date of the GSD file in the format yyyymmdd.
This date also stands for the release date of the file.
Example:
GSDML-V2.2-Leuze-BCL248i-20090503.xml
The GSD file is located directly in the product area under Downloads, i.e., for the BCL248i:
www.leuze.com > Products > Identification > Bar code identification > Stationary bar code readers >
BCL200i > BCL248i… > Downloads > Software/Driver
If parameters are changed in the project tool, for example, these changes are stored by the PLC 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. The file is not changed by the system either.
Leuze electronic GmbH + Co. KG BCL 248i 41
Starting up the device - Configuration
The functionality of the BCL248i is defined via parameter sets. The parameters and their functions are
structured in the GSD file using modules. 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 BCL248i on the PROFINET-IO, 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.
For the default settings of the BCL248i, please refer to the following module descriptions.
8.3.3
Step 3 – Hardware configuration of the S7 PLC: Configuration
Ä Configure the PROFINET-IO system with the HW Config of the SIMATIC Manager by inserting the
BCL248i into your project.
ð Here, an IP address is assigned to a unique "device name".
Fig.8.1: Assignment of the device names to IP addresses
8.3.4
Step 4 – Transmit the configuration to the IO controller
Ä Transmit 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 activities:
• Check of device names
• Assignment of the IP addresses that were configured in the HW Config to the IOdevices
• Establishment of a connection between the IOController and configured IOdevices
• Cyclical data exchange
NOTICE
Participants that have not been "named" cannot be contacted yet at this point in time.
Leuze electronic GmbH + Co. KG BCL 248i 42
Starting up the device - Configuration
8.3.5
Step 5 – Set device name – device naming
The PROFINET-IO device has a unique MAC address that is part of the factory settings. You can find this
on the name plate of the bar code reader.
This information is used to assign a unique, plant-specific device name ("NameOfStation") to the device via
the "Discovery and Configuration Protocol" (DCP).
The PROFINET-IO also uses the "Discovery and Configuration Protocol" (DCP) for the IP address assignment during each system boot-up if the IO device is located in the same subnet.
NOTICE
All BCL248i participants in a PROFINET-IO network must be located in the same subnet.
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
Ä Select the respective BCL248i bar code reader for the "device naming" based on its MAC address.
ð This 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.8.2: Assigning the device names to the configured IOdevices
NOTICE
Multiple BCL248i can be distinguished by the MAC addresses displayed. The MAC address
may be found on the name plate of the respective bar code reader.
Leuze electronic GmbH + Co. KG BCL 248i 43
Starting up the device - Configuration
Assignment of MAC address – IP address – individual device name
Ä Assign 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").
ð From now on, and when programming, only the unique "device name" is used.
8.3.6
8.3.7
Fig.8.3: MAC address – IP address – individual device name
Step 6 – Check device name
Ä After completing the configuration phase, recheck the "device names" that have been assigned. Ensure
that these are unique and that all participants are located in the same subnet.
Manually setting the IP address
If you would like to directly access webConfig, the IP address must be set manually.
On delivery, the device has the following network address:
• IP address: 192.168.60.101
• Subnet mask: 255.255.255.0
Setting the IP address via PC/laptop

8.3.8
MAC address
The MAC address (Media Access Control address) of the device may be found on the name plate.
Address Link Label
The "Address Link Label" is an additional stick-on label that is affixed to the device.
Fig.8.4: Example: "Address Link Label"
• The "Address Link Label" contains the MAC address (Media Access Control address) of the device and
makes it possible to enter the IP address and the device name manually.
The area of the "Address Link Label" on which the MAC address is printed can be separated from the
remainder of the stick-on label if necessary using the perforation.
• The "Address Link Label" can be removed from the device and affixed in the installation and layout diagrams to designate the device.
• Once it is affixed in the documents, the "Address Link Label" establishes a unique reference between
the mounting location, the MAC address or the device, and the associated control program.
There is no need for time-consuming searching, reading, and manually writing down of the MAC addresses of every device that is installed in the system.
Leuze electronic GmbH + Co. KG BCL 248i 45
Starting up the device - Configuration
NOTICE
Each device with Ethernet interface is uniquely identified via the MAC address assigned during
production.
The MAC address is also listed on the name plate of the device.
If multiple devices are commissioned in a system, the MAC address of each installed device
must be correctly assigned, e.g., during programming of the control.
Ä Remove the "Address Link Label" from the device.
Ä If necessary, add the IP address and the device name to the "Address Link Label".
Ä Affix the "Address Link Label" in the documents, e.g., in the installation diagram, according to the posi-
tion of the device.
8.3.9
8.3.10
Ethernet host communication
This chapter is only of interest if an additional IP address independent of the device name is to be established for an additional communication channel, e.g. TCP/IP.
The control generally also assigns an IP address to the actual device name. The Ethernet host communication enables the configuration of connections to an external host system. Both UDP as well as TCP/IP (in
either client or server mode) can be used. The connection-free UDP protocol is used primarily to transfer
process data to the host (monitor operation). 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 in your application, you must also define whether the BCL248i
is to operate as a TCP client or as a TCP server. Both protocols can be activated simultaneously and used
in parallel.
Ä Contact your network administrator to determine which communication protocol is used.
TCP/IP
Ä Activate the TCP/IP protocol.
Ä Set the TCP/IP mode of the bar code reader.
TCP client mode
In TCP client mode, the bar code reader actively establishes the connection to the superior host system
(PC/PLC as server). The bar code reader 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 bar code
reader determines when and with whom a connection is established.
Ä With a bar code reader as TCP client, set the following values:
• IP address of the TCP server (normally the PLC/host computer)
• Port number of the TCP server
• Timeout for the wait time for an answer from the server
• Repetition time for renewed communication attempt following a timeout
TCP server mode
In TCP server mode, the superior host system (PC/PLC) actively establishes the connection and the connected bar code reader 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 bar code reader (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/PLC as client), the bar code reader (in server mode) accepts the
connection. Data can then be sent and received.
Ä With a bar code reader as TCP server, set the following values:
• Port number for the communication of the bar code reader with the TCP clients
The corresponding adjustment options can be found in the webConfig tool under Configuration > Com-
munication > Host communication.
Leuze electronic GmbH + Co. KG BCL 248i 46
Starting up the device - Configuration
8.3.11
UDP
The bar code reader requires from the user the IP address and the port number of the communication partner. In the same way, the host system (PC/PLC) also requires the set IP address of the bar code reader
and the selected port number. By assigning these parameters, a socket is formed via which the data can
be sent and received.
Ä Activate the UDP protocol
Ä Set the following values:
• IP address of the communication partner
• Port number of the communication partner
The corresponding adjustment options can be found in the webConfig tool under Configuration > Com-
munication > Host communication.
All other parameters required for the reading task, such as setting the code type and number of digits, etc.,
are set using the engineering tool of the PLC with the aid of the various available modules (see chapter 8.4
"Commissioning via the PROFINET-IO").
8.4 Commissioning via the PROFINET-IO
8.4.1
General information
The BCL248i is designed as a modular field device. The PROFINET-IO functionality of the device is defined via parameter sets that are combined in modules (slots) and sub-modules (sub-slots). The further addressing within subslots is then accomplished via an index. The modules are included in a XML-based
GSD file, which is supplied as an integral part of the device. By using a user-specific configuration tool,
such as, e.g.SIMATIC Manager for the Siemens PLC, the required modules are integrated into a project
during commissioning and its settings and parameters are configured accordingly. These modules are provided by the GSD file.
NOTICE
All input and output modules described in this documentation are described from the viewpoint
of the control (IO controller):
- Input data arrives at the control.
- Output data is sent out by the control.
Detailed information on how to prepare the control and the GSD file see chapter 8.3 "Configuration steps
for a Siemens SimaticS7 control".
For the default settings of the BCL248i, please refer to the following module descriptions.
NOTICE
Ä 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 BCL248i.
From the perspective of the device, a distinction is made between PROFINET‑IO parameters and internal
parameters. PROFINET-IO parameters are all parameters that can be changed via the PROFINET-IO and
are described in the following modules. Internal parameters, on the other hand, can only be changed via a
service interface and retain their value even following a PROFINET-IO configuration.
During the configuration process, the BCL receives parameter telegrams from the IO controller (PLC). Before this is evaluated and the respective parameter values are set, all PROFINET‑IO parameters are reset
to default values. This ensures that the parameters of modules that are not selected are set to the default
values.

8.4.2
Permanently defined parameters/device parameters
On the PROFINET-IO, parameters may be stored in modules or may be defined permanently in a
PROFINET-IO participant.
Depending on the configuration tool, the permanently defined parameters are called "common" parameters
or device-specific parameters.
These parameters must always be present. They are defined outside configuration modules and are thus
connected to the base module (DAP: Device Access Point) that is addressed via Slot0/Subslot0
In SIMATIC Manager, the permanently defined parameters are set via object properties of the device. The
module parameters are configured 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 device parameters that are permanently defined in the BCL248i (DAP Slot0/
Subslot0) but are configurable. These parameters always exist and are available independent of the modules.

8.5 Overview of the project modules
When using PROFINET-IO modules, the parameters are assembled dynamically, i.e., only the parameters
that were selected by the activated modules are changed.
The BCL has parameters (device parameters) that must always be present. These parameters are defined
outside of modules and are thus linked to the base module (DAP).
In the current version, a total of 58modules are available for use. A device module (DAP, see chapter 8.4.2
"Permanently defined parameters/device parameters") is used for basic configuration of the BCL248i and
is permanently integrated into the project. Further modules may be included into the project according to
requirements and application.
The modules fall into the following categories:
• Parameter module for configuring the BCL248i.
• Status or control modules that influence the input/output data.
• Modules that may include both parameters and control or status information.
A PROFINET-IO module defines the existence and meaning of the input and output data. In addition, it defines the necessary parameters. The arrangement of the data within a module is defined.
The composition of the input/output data is defined via the module list.
The BCL248i interprets the incoming output data and triggers the appropriate reactions in the BCL248i.
The interpreter for processing the data is adapted to the module structure during 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 IO controller.
During the startup or initialization phase, the BCL248i sets the input data to an initial value (usually = 0).
NOTICE
The modules can be grouped together in any order in the engineering tool. Note, however, that
many BCL248i modules contain linked data (e.g., the decoding result modules 20-41). It is important to maintain the consistency of these data.
The BCL248i offers 58different modules. Each of these modules may only be selected once;
otherwise, the BCL248i ignores the configuration.
The BCL248i checks its max. permissible number of modules. The control also reports an error
if the input and output data across all selected modules exceed a total length of 1024bytes.
The specific limits of the individual modules of the BCL248i can be found in the GSD file.
The following module overview shows the characteristics of the individual modules:

If this parameter is set, a decoded bar code is only completely decoded after the scanning beam
has exited the entire bar code. This mode is useful if the quality of the bar code is to be assessed, since more scans are now available for the quality evaluation of the bar code.
This parameter should be set if the AutoControl function is activated (see chapter 8.15.3 "Module 92 – AutoControl"). If the parameter is not set, the bar code is immediately decoded and processed further as soon as all necessary bar code elements are available
If this parameter is set, a decoded bar

8.7.1
Module 10 – Activations
PROFINET-IO module identifier
Module ID: 1010
Submodule ID:1
Description
The module defines the control signals for the reading operation of the bar code reader. It is possible to select between standard reading operation and handshake operation.
In handshake operation, the control must acknowledge the data reception via the ACK bit before the new
data is written into the input area.
After acknowledging the last decoding result, the input data is reset (filled with zeros).

Output data length

NOTICE
If several bar codes are decoded in sequence without the acknowledge mode having been activated, the input data of the result modules are overwritten with the respective most recently read
decoding result.
If a data loss in the control is to be avoided in such a case, mode 1 (with ACK) should be activated.
If multiple decoding results occur within one reading gate, it is possible - dependent on the cycle
time - that only the last decoding result is visible on the bus. In this case, the acknowledge mode
MUST be used. There is otherwise a risk of data loss.
Multiple, individual decoding results may occur within one reading gate if module12 – Multi-label (see chapter 8.7.3 "Module 12 – Multi-label") or one of the identifier modules (see chapter
8.10 "Identifier") is used.
Data reset behavior
If the data reset control bit is activated, the following actions are carried out:
1. Deletion of decoding results that may still be stored.
2. Reset of module13 – Fragmented read result (see chapter 8.7.4 "Module 13 – Fragmented read result"), i.e., even a partially transmitted read result is deleted.
3. Deletion of the input data areas of all modules.
Exception: The input data of module60 – device status (see chapter 8.11.1 "Module60–Device status") is not deleted. For the status byte of decoding result modules20…27 (see chapter 8.8.2 "Modules 21-29 – Decoding result"), the two toggle bytes and the reading gate status remain unchanged.

This module is used to set the maximum and minimum number of bar codes which are to be decoded
within a reading gate.
If parameter "minimum number of bar codes" = 0, it is not taken into account at the decoder control. If it is
not equal to 0, this means that the bar code reader expects a number of labels within the set range.
If the number of decoded bar codes is within the set limits, no additional "No Reads" are output.
NOTICE
When using this module, the ACK mode should be activated (see chapter 8.7.1 "Module 10 –
Activations", "Mode" parameter). Otherwise there is a risk of losing decoding results if the control is not fast enough.

If this criterion has been activated,
the bar code direction is used to
determine whether the bar codes
are identical.
If this parameter is not equal to 0,
the bar code position in the scanning beam is used to determine
whether identical bar codes have
already been decoded. In this
case, a +/- bandwidth must be
specified in 1/10degrees, within
which the same bar code is permitted to be in the scanning
beam.
If this parameter is not equal to 0,
the decoding time (time at which
the bar code was decoded) is
used to determine whether identical bar codes have already been
detected. For this purpose, a time
difference in milliseconds is specified. It ensures that identical bar

8.12 Switching inputs/outputs SWIO1/2
These modules define the mode of operation of the two digital switching inputs and outputs (I/Os). They are
separated into individual modules for configuring the individual I/Os and a shared module for signaling the
status and controlling all I/Os.
8.12.1
Parameters for operating as an output
Start-up delay
With this setting, the output pulse can be delayed by the specified time (in ms).
Switch-on time
Defines the switch-on time period for the switching input. Any activated switch-off function then no longer
has any function.
A value of 0 causes the output to be set statically; this means that the selected input function(s) activates
the output, and the selected switch-off function(s) deactivates it again.

Fig.8.6: Example2: Start-up delay >0 and switch-on time >0
In example2, the activation duration of the output is only dependent on the selected switch-on time; the
switch-off signal has no effect.
1 Switch-on signal 4 Start-up delay
2 Switch-off signal
3 Output
Fig.8.7: Example3: Start-up delay >0 Switch-off signal prior to lapsing of the start-up delay
If the output is again deactivated via the switch-off signal before the start-up delay lapses, only a brief pulse
appears at the output following the start-up delay.
Comparison functionality
If, for example, the switching output is to be activated after four invalid read results, the comparative value
is set to 4 and the switch-on function is configured to "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 fulfill 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 with the I/O data in the I/O status and control module; furthermore,
the reset mode parameter enables automatic resetting upon reaching the comparative value. 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 at reading gate start is rather unsuited for this module since it causes the
event counter to be reset on each reading gate start. Suitable as switch-off function for this example is the
valid read result function; otherwise, all switch-off functions are deactivated.
8.12.2
Parameters for operating as an input
Debounce time
Parameter for setting the software debounce time for the switching input. The definition of a debounce time
extends the signal transition time accordingly.
If the value of this parameter = 0, no debouncing takes place; otherwise, the configured value represents
the duration in milliseconds for which the input signal must be present and stable.
1 Input signal 3 Start-up delay td_on
2 Output signal 4 Switch-on time ton
5 Switch-off delay td_off
Fig.8.8: Start-up behavior in input mode
Start-up delay td_on
If the value of this parameter = 0, no start-up delay occurs for the activation of the input function; otherwise,
the configured value represents the time in milliseconds by which the input signal is delayed.
Switch-on time ton
This parameter specifies the min. activation duration for the selected input function in milliseconds.
The actual activation duration is calculated from the switch-on time as well as the switch-off delay.
Switch-off delay td_off
This parameter specifies the duration of the switch-off delay in milliseconds.

comparison
If this parameter is set,
the basic condition for a
positive reference code
7.0 Bit 0: Completeness com-
comparison is that all
mandatory bar codes
that are to be read within
a reading gate were actually read. If this condition is not satisfied, no
positive reference code
comparison is achieved.

Input data
None
Parameter string describing
the content of the reference
bar code.
Note: You can also use the
two placeholder characters
that are stored in the "Wildcard character" and "Don't
care character" parameters.
If the string is empty, no
comparison takes place. If
the most recently stored
character is the wildcard
character, the comparison is
only carried out up to the
character before this wildcard character. In this way it
is possible to switch off a
comparison according to bar
code length.
