In order to select the right mounting location, several factors must be considered:
• Size, orientation, and position tolerance of the barcodes on the objects to be scanned.
i
• The reading field of the BCL 508
• The resulting minimum and maximum reading distance from the respective reading field (see chapter 5.5 "Reading field curves / optical data").
• The permissible line lengths between the BCL 508 on which interface is used.
• The correct time for data output. The BCL 508 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 4.4.
Notice!
The beam exits the BCL 508i as follows for the respective devices:

3.5 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 508 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.

With a BCL 508i 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 508 requires information from the user regarding the local port of the BCL 508 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 508 sent and received.
With a BCL 508i as TCP server, also set the following values:

General information

The integrated fieldbus connectivity = i contained in the barcode readers of the BCL 500 series facilitates the use of identification systems which function without connector 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 barcodes, the barcode readers of the BCL 500 proven CRT decoder with code fragment technology:
The proven code fragment technology (CRT) enables barcode readers of the BCL 500 series to read barcodes with a small bar height, as well as barcodes with a damaged or soiled print image.

With the aid of the CRT decoder, barcodes can also be read without problem in other demanding situations, such as with a large tilt angle (azimuth angle or even twist angle).

The BCL 508 the reading field. This opens a time window ("reading gate") in the BCL 508 process during which the barcode reader has time to detect and decode a barcode.
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 508 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.
A multi-language display with buttons is used to operate the BCL 508 isation purposes. Two LEDs provide additional optical information on the current operating state of the device.
The four freely configurable switching inputs/outputs "SWIO 1 … SWIO 4" can be assigned various functions and control e.g. activation of the BCL 508 PLC.
System, warning and error messages provide assistance in set-up/troubleshooting during commissioning and read operation.

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 barcode is automatically transported through the scan line.
The integrated code fragment technology permits twisting of the barcode (tilt angle) within certain limits. These are dependent on the transport speed, the scanning rate of the scanner and the barcode properties.
Areas of application of the line scanner
The line scanner is used:
• when the bars of the barcode are printed in the conveying direction ('ladder arrange­ment').
• with barcodes having very short bar lengths.
• when the ladder code is turned out of the vertical position (tilt angle).
• when the scanning distance is large.

4.4.2 Line 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 508 larger areas or spaces for barcodes. The reading field height (and the scan line length useful for evaluation) depends on the reading distance due to the optical beam width 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 barcode are printed perpendicular to the conveying direction ('picket fence arrangement').
• when reading stationary objects.
• when the barcode is turned out of the horizontal position.
• when the scanning distance is large.
• when a large reading field (reading window) has to be covered.

4.4.3 Omnidirectional reading

In order to read arbitrarily oriented barcodes on an object, at least 2 barcode readers are necessary. If the barcode is not printed over-square, i.e. bar length > code length, barcode readers with integrated code fragment technology are necessary.
