Fast commissioning / operating principle

3.4 Preparatory Ethernet settings

 Connect the +18 … 30VDC supply voltage (typ. +24VDC); the BCL 308i starts up.

As a first step, you need to set the communication parameters of the BCL 308i. You can make the necessary settings via the webConfig tool. Detailed information on this topic can be found in chapter 10.

3.4.1 Manually setting the IP address

If your system does not include a DHCP server or if the IP addresses of the devices are to be set permanently, proceed as follows:

 Have the network administrator specify the data for IP address, net mask and gateway

address of the BCL 308i.

 Set these values on the BCL 308i:

Via webConfig:

Configuration -> Communication -> Ethernet interface

Notice!

If the setting is performed via the webConfig tool, the BCL 308i must be restarted. Only after this restart is the set IP address accepted and does it become active.

3.4.2 Automatically setting the IP address

If your s ystem includes a DHCP server that is to be used to assign the IP addresses, proceed as follows:

 Activate the DHCP Client mode in the BCL 308i.

Via webConfig:

Configuration -> Communication -> Ethernet interface

Activate the DHCP = ON setting there.

Fast commissioning / operating principle

3.4.3 Defining Ethernet host communication

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, you must also define whether the BCL 308i is to operate as a TCP client or as a TCP server.

Both protocols can be activated simultaneously and used in parallel.

 Contact your network administrator to determine which communication protocol is used.

3.4.4 TCP/IP

 Activate the TCP/IP protocol

 Set the TCP/IP mode of the BCL 308i

In TCP client mode, the BCL 308i actively establishes the connection to the primary host system (PC / PLC as server). The BCL 308i 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 BCL 308i determines when and with whom a connection is established!

 With a BCL 308i as TCP client, also 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

In TCP server mode, the primary host system (PC / PLC) actively establishes the connection and the connected BCL 308i waits for the connection to be setup. The TCP/IP stack requires information from the us which the connection requests of a client application (host system) are to be accepted. If there is a connection request and a connection is established by the primary host system (PC / PLC as client), the BCL 308i (server mode) accepts the connection. Data can then be sent and received.

 With a BCL 308i as TCP server, also set the following values:

•Port n

umber for the communication of the BCL 308i with the TCP client

The corresponding adjustment options can be found:

3.4.5 UDP

The BCL 308i requires from the user the IP address and the port number at which the communication partner receives data. Correspondingly, the host system (PC / PLC) now also requires the set IP address of the BCL 308i and the selected port number. This assignment notifies both communication partners of which port the data is received on.

 Activate the UDP protocol

 Also set the following values:

•IP a

ddress of the communication partner

•Port number of the communication partner

The corresponding adjustment options can be found:

•Via webConfig:

3.5 Further settings

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:

Configuration -> Decoder

• Control of the decoding

 Configure the connected switching inputs according to your requirements. To do

this, first set the I/O mode to Input and then configure the switching behavior:

•Via webConfig:

Configuration -> Device -> Switching inputs/outputs

• Control of the switching outputs

 Configure the connected switching outputs according to your requirements. To do

Operation of BCL 308i

After voltage (18 … 30 V DC) 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 (PLC/PC) via the Ethernet.

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 308i can be operated and configured using the integrated webConfig tool via the USB service interface; alternatively, the bar code rea tion commands via the host/service interface.

The BCL 308i 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 308i for the read process during which the bar code reader has time to detect

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. Alternative activation options include online commands via the host interface and the autoReflAct func-

tion. Through the read operation, the BCL 308i collects additional useful pieces

nosis 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 display in English with buttons is used to operate the BCL 308i as well as for visualization purposes. Two LEDs provide additional optical information on the cu ating 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 308i or external devices, such as a PLC.

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.

In this way, the BCL 308i can also scan larger areas or spaces for bar codes. The reading field height (and the scan line length useful for evaluation) depends 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

• when a large reading field (reading window) has to be covered.

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

4.5 Fieldbus systems

Various product variants of the BCL 300i series are available for connecting to different fieldbus systems such as PROFIBUS DP, ProfiNet and Ethernet.

4.5.1 EtherNet

The BCL 308i is designed as an Ethernet device (acc. to IEEE 802.3) with a standard baud rate of 10/100 Mbit. A fixed MAC ID is assigned to each BCL 308i by the manufacturer; this ID cannot be changed.

The BCL 308i automatically supports the transmission rates of 10 Mbit/s (10BaseT) and 100 Mbit/

The BCL 308i features multiple M12 connectors / sockets for the electrical connection of the supply voltage, the interface and the switching inputs and outputs. Additional information on the electrical connection can be found in Kapitel 7.

The BCL 308i supports the following protocols and services:

For communication with the superior host system, the corresponding TCP/IP protocol (client/server mode) or UDP must be selected.

Further information on commissioning can be found in Kapitel 10.

4.5.3 Ethernet – linear topology

The innovative further development of the BCL 308i with integrated switch functionality offers the option of connecting multiple bar code readers of type BCL 308i to one another without direct connection to a switch. In addition to the classic "star topology", a "linear topology" is thus also possible.

Figure 4.12: Ethernet with linear topology

Each participant in this network requires its own unique IP address which must be ass via the display or webConfig tool; alternatively, the DHCP method can also be used.

The maximum length of a segment (connection from the hub to the last participant) is limited to 100m.

4.6 Heater

For low-temperature applications to min. -35°C (e.g. in cold storage), the bar code readers of the BCL 308i series can optionally be permanently fitted with a built-in heating and these

bar code readers purchased as separate device models.

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 4.13: Reflector a

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 308i 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 308i 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 308i 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!

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 308i, 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 308i to the supply voltage. This is followed by the self test and the changeover to read operation. The "PWR" LED light

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.

Mounting location

Notice!

The mounting location is to be selected such that it does not expose the BCL 308i with heating directly to a cold air stream. To achieve an optimal heating effect, the BCL 308i 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 308i 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.

These values are based on operation with unconnected switching output

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 308i (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.

Installation and mounting

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 308i 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 permissi on which interface is used.

• 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 and chapter 7.

Notice!

The beam of the BCL 308i exits:

• parallel to the housing base in the case of the line scanner

• at 105 degrees from the housing

• 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 308i 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.

6.3.2 Avoiding total reflection – Line scanner

Bar code

The BCL 308i should be 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.

…

Bar code

The BCL 308i with deflection mirror should be mounted parallel to the bar code.

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

Figure 6.6: Total reflection – line sca

6.3.3 Avoiding total reflection – deflection mirror scanner

For the BCL 308i 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 308i can be installed parallel to the bar code (rear housing wall).

Bar code

The BCL 308i 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 308i with oscillating mirror, the laser beam exits at an angle of 90° to vertical.

For the BCL 308i 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 308i with oscillating mirror must be inclined upward or downward 20° … 30°!

Notice!

Mount the BCL 308i 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 308i with oscillating mirror

6.3.5 Mounting location

 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 308i 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

 For devices with integrated heating, also observe the following points:

•Mount the BCL 308i 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 308i 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 308i and bar code.

The optimum alignment of the BCL 308i 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).

Figure 6.9:Reading angle for the line scanner

Up to 254 bar code readers can be networked. For this purpose, each participating BCL 308i is assigned the respective network address via the webConfig Tool. This address must be

specified by the network administrator. Alternatively, the BCL 308i can also be configured as a DHCP client and then automatically receive its address

Information on the necessary configuration steps can be found in chapter 10.

7.4.1 Ethernet wiring

A Cat. 5 Ethernet cable should be used for wiring. For the connection on the BCL 308i, a "KDS ET M12 / RJ 45 W - 4P" adapter is available

into which the standard network cable can be plugged. If no standard network cables are to be used (e.g. due to lacking IP… protection class), you

can use the "KB ET - … - SA" user-configurable cable on the BCL 308i, see table 13.9 connection cables for the BCL 308i" on page 141.

The individual BCL 308i devices in a linear topology are connected with the "KB ET - … - SSA" cable, see table 13.9 "Bus connection cables for the BCL 308i" on page 141.

For unavailable line lengths, you can configure your cables 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

This chapter describes basic configuration steps which you can carry out via the webConfig tool.

Via the webConfig tool

The most convenient way to configure the BCL 308i is via the webConfig tool. To use the webConfig tool, you need to establish a USB connection between the BCL 308i and a PC/laptop.

Notice!

Notes on the use of the webConfig tool can be found in chapter 9 "Leuze webConfig tool" on page 102

10.1 Measures to be performed prior to the initial commissioning

 Before commissioning, familiarize yourself with the operation and configuration of the

BCL 308i.

 Before connecting the supply voltage, recheck all connections and ensure that they have

been properly made.

The description of the electrical connections can be found in chapter 7.

92BCL308i Leuze electronic

Commissioning and configuration

10.2 Starting the device

 Connect the +18 … 30VDC supply voltage (typ. +24VDC); the BCL 308i starts up and

the bar code reading window appears on the display.

Notice!

The BCL 308i can decode the following code types in the standard setting:

• Code 128 Number of digits 4 … 63

• 2/5 Interleaved number of digits 10

• Code 39 Number of digits 4 … 30

• EAN 8 / 13 Number of digits 8 and 13

• UPC Number of digits 8

• Codabar Number of digits 4 … 63

• Code 93 Number of digits 4 … 63

• Code GS1 Data Bar OMNIDIRECTIONAL

• Code GS1 Data Bar LIMITED

• Code GS1 Data Bar EXPANDED

Deviations from these settings must be set via the webConfig tool. See "Leuze webConfig tool" on page 102.

As a first step, you need to set the communication parameters of the BCL 308i.

10.3 Setting the communication parameters

With the communication parameters, you determine how data is exchanged between BCL 308i and host system, monitor PCs etc.

The communication parameters are independent of the topology in which the BCL 308i is operated (see "Ethernet topologies" on page 79).

10.3.1 Manually setting the IP address

If your system does not include a DHCP server or if the IP addresses of the devices are to be set permanently, proceed as follows:

 Have the network administrator specify the data for IP address, net mask and gateway

address of the BCL 308i.

 Set these values on the BCL 308i:

Via webConfig tool

 In the main menu, select Configuration, submenu Communication -> Ethernet interface.

Notice!

If the setting is performed via the webConfig tool, the BCL 308i must be restarted. Only after this restart is the set IP address accepted and does it become active.

TNT 35/7-24V

Commissioning and configuration

10.3.2 Automatically setting the IP address

If your system includes a DHCP server which is to be used to assign the IP addresses, proceed as follows:

 Activate the DHCP Client mode in the BCL 308i.

Via webConfig:

Configuration -> Communication -> Ethernet interface

Activate the DHCP = ON setting there.

Notice!

The BCL 308i responds to ping commands. A simple test to determine whether the address assignment was successful is to enter the previously configured IP address in a ping command (e.g. "ping 192.168.60.101" in a command line window under Windows).

10.3.3 Ethernet host communication

If you would like to use the TCP/IP protocol, you must also define whether the BCL 308i is to operate as a TCP client or as a TCP server.

Both protocols can be activated simultaneously and used in parallel.

 Contact your network administrator to determine which communication protocol is used.

10.3.4 TCP/IP

 Activate the TCP/IP protocol

 Set the TCP/IP mode of the BCL 308i

connection. In this case, the BCL 308i determines when and with whom a connection is established!

 With a BCL 308i as TCP client, also 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

94BCL308i Leuze electronic

In TCP server mode, the primary host system (PC / PLC) actively establishes the connection and the connected BCL 308i waits for the connection to be setup. The TCP/IP stack requires information from the user regarding the local port of the BCL 308i (port number) on which the connection requests of a client application (host system) are to be accepted. If there is a connection request (PC / PLC as client), the BCL 308i (server mode) accepts the connection. Data can then be sent and received.

 With a BCL 308i as TCP server, also set the following values:

The corresponding adjustment options can be found:

10.4 Additional settings for the BCL 308i

After the basic configuration of the operating mode and the communication parameters, you need to carry out further settings via the webConfig tool:

• Decoding and processing the read data

• Control of the decoding

• Control of the switching outputs

10.4.1 Decoding and processing the read data

The BCL 308i offers the following options:

• Setting the number of labels to be decoded for each reading gate (0 … 64). This is done via the Max. no. of labels parameter.

• Definition of up to 8 different code types. Labels that match one of the defined code types are decoded. Further parameters can be set for each code type:

• The code type (symbology)

• The Number of digits: either up to 5 different numbers of digits (e.g., 10, 12, 16,

20, 24), or a range (Interval mode) (e.g., 2 … 10, 12, 16, 26)

• The Reading reliability: the set value specifies how many times a label must

be read and decoded with the same result before the result is accepted as valid

• Additional code type specific settings (in the webConfig tool only)

• Check digit method used for decoding as well as the type of Check digit out-

put for the read result. The two possibilities for the latter are Standard (corre- s

ponds to the standard for the selected code type/symbology) and not Standard.

 Define at least one code type with the desired settings.
