4 Functions

A B C D

B C D E F G H A B DC

This chapter describes the functions of the code reader:

• Camera operating modes (see chapter 4.1 "Camera operating modes")

• Reference code comparison (see chapter 4.2 "Reference code comparison")

• Code quality (see chapter 4.3 "Code quality")

• webConfig tool (see chapter 4.4 "Leuze webConfig tool")

4.1 Camera operating modes

The camera operating mode defines how the code reader starts a read process and decodes the codes if a code is located in the read field.

Functions

4.1.1

4.1.2

4.1.3

Single trigger mode

In the "Single trigger mode" camera operating mode, the code reader captures one image and attempts to decode it. Under uniform conditions, this camera operating mode makes fast decoding possible.

Reading gate control

The "Reading gate control" camera operating mode is activated upon shipment from the factory. The reading gate control opens a time window for the read process in the code reader – the reading gate. In this time window, the code reader can capture and decode one or more codes.

Burst mode

In the "Burst mode" camera operating mode, the code reader captures multiple images in quick succession after activation by a trigger signal. The maximum number of image acquisitions can be set.

• Decoding occurs following image capture, thereby allowing the codes to be detected more quickly.

• As soon as the decoding result corresponds to the settings, the decoding stops the capture of the remaining images.

1 Continuous image capture 2 Decoding 3 Output of the read data

Fig.4.1: "Burst mode" camera operating mode

Leuze electronic DCR 202i 18

Functions

4.1.4

4.1.5

Presentation mode

In the "Presentation mode" camera operating mode, the code reader is in the idle state in a kind of wait mode.

In the event of a change in the image area, e.g., by holding up a code, the code reader captures images with illumination (as previously configured) until a code is read successfully. The code reader then switches back to the wait mode and the illumination switches off after a few seconds.

Reading the same code multiple times

To prevent the same code from being read and output repeatedly in the "Presentation mode" camera operating mode, a delay time can be defined that must elapse before a code can be read again.

The delay time is set or deactivated with the webConfig tool (see chapter 9 "Commissioning – Leuzeelectronic webConfig tool").

Configuration > Control > Reread delay

Sensitivity

This function can only be activated in the "Presentation mode" camera operating mode. You can set the sensitivity threshold at which a change in the field of view is to be detected: 0…100.

• 0 = not sensitive

• 100 = sensitive

Continuous mode

In the "Continuous mode" camera operating mode, the code reader operates continuously in process mode. In this mode, image acquisition is started again immediately after an image has been processed. An external trigger signal is not required.

Image frequency

You can limit the maximum number of images per second. A reduction in image frequency is recommended for slow applications where the object with the code moves slowly past the code reader. Consider here the decoding time per decoding.

• It is recommended to limit the decoding time.

• It is recommended to deactivate the NOREAD output.

4.2 Reference code comparison

With the reference code comparison, the code reader compares the actual decoding result with a stored reference code – the exact code content is compared.

Options for teaching-in a new reference code:

• webConfig tool: Configuration > Decoder > Reference

• Online command via the host interface

• Signal via a digital switching input

• TEACH function on the control panel of the code reader (not with devices with stainless steel housing)

In the webConfig tool, the exact code content can be entered for comparison.

Regular expressions

As an alternative to the exact code comparison, regular expressions can be used for a partial comparison.

Regular expressions can only be entered via the webConfig tool (see chapter 9 "Commissioning – Leuzeelectronic webConfig tool").

Detailed information on regular expressions can be found on the Internet under Perl Compatible Regular Expressions (PCRE) http://www.pcre.org/.

Leuze electronic DCR 202i 19

Functions

• Example1

The code reader is to perform a partial comparison of two characters "42". Any number of characters and content may precede the string "42".

• Comparison string entered in the webConfig tool: 42

• Positive reference code comparison (match): 123425

• Negative reference code comparison (mismatch): 12345

• Example2

The code reader is to perform a partial comparison of two characters "42". Beginning with the string "42", any number of characters and content may follow.

• Comparison string entered in the webConfig tool: ^42

• Positive reference code comparison (match): 42345

• Negative reference code comparison (mismatch): 12345

NOTICE

Using space characters with regular expressions!

Ä When entering regular expressions, note the use of space characters.

4.3 Code quality

Overview

To check the code quality, you can activate the Code quality function. This function determines the code quality for bar codes and 2D-codes in compliance with ISO/IEC15416 and ISO/IEC15415.

NOTICE

Activating the Code quality function increases the decoding time.

The code quality is given as follows: A…F

• A = High quality

• F = Low quality

The following options are available:

• Determination of individual features for bar codes and 2D-codes

• Setting of a minimum quality (= NOMINALMINIMUM)

• Output of each feature via the interface and as a programmable switching output

ISO/IEC15416 mode: Individual features for bar codes

• Overall quality

• Symbol contrast (SC)

• Modulation (MOD)

• Decodability

Overall quality

The "Overall quality" feature corresponds to the lowest ascertained individual quality. If multiple codes are decoded, the minimum quality is output via the switching output for the first found code only.

4.4 Leuze webConfig tool

The webConfig configuration tool offers a graphical user interface for the configuration of the code reader via a PC (see chapter 9 "Commissioning – Leuzeelectronic webConfig tool").

The wizard of the webConfig tool can be used to easily configure the code reader in just a few steps.

6.1 Determining the mounting position of the code reader

Mounting

6.1.1

Selecting a mounting location

NOTICE

The size of the code module influences the maximum reading distance and the width of the reading field. Therefore, when selecting a mounting location and/or the suitable code label, take into account the different reading characteristics of the code reader with various code modules.

NOTICE

Observe when choosing the mounting location!

Ä Make certain that the required environmental conditions (humidity, temperature) are main-

tained.

Ä Avoid possible soiling of the reading window due to liquids, abrasion by boxes, or packaging

material residues.

Ä Ensure the lowest possible chance of damage to the code reader through mechanical colli-

sion or jammed parts.

Ä Avoid possible ambient light influence (no direct sunlight).

Take the following factors into account when selecting the correct mounting location:

• Size, orientation, and position tolerance of the bar codes or Data Matrix codes on the objects to be scanned.

• The reading distance resulting from the code size and code type (see chapter 6.1.3 "Determining the reading distance").

• Time of data output.

Position the device 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 permissible line lengths between code reader and host system depending on which interface is used.

• Visibility of the control panel and access to the control buttons.

• No direct sunlight and/or no strong ambient light on the code that is to be read.

Leuze electronic DCR 202i 25

Mounting

10° … 20° 10° … 20°

Observe the following criteria for the best read results:

• The reading distance is located in the middle part of the read field (see chapter 6.1.3 "Determining the reading distance").

• There is no direct sunlight and protect against ambient light effects.

• The code labels are of good print quality and have good contrast ratios.

• Do not use glossy labels.

• The bar code or DataMatrix code is moved past the reading window with a tilt angle or angle of inclination of 10°… 20° (see chapter 6.1.2 "Avoiding total reflection").

6.1.2

Avoiding total reflection

If the illumination light of the code reader is directly incident on the surface of the code at an angle of 90°, total reflection occurs. The illumination light directly reflected by the code label may overload the code reader and thereby result in non-reading of the code.

Ä Mount the code reader with a tilt angle or angle of inclination of ±10°… 20° from vertical.

Recommended tilt angle or angle of inclination: 10°…20° 1 Code label 2 Mounting with tilt angle 3 Mounting with angle of inclination

Fig.6.1: Mounting with tilt angle or angle of inclination

6.1.3

Determining the reading distance

In general, the read field of the code reader becomes larger with increasing reading distance. This also results in a decrease in the resolution, however.

The following figures show typical reading distances for the individual optics models of the code reader.

NOTICE

Code reading while in motion is dependent on the code type, code size, cell or modulus size of the code and the position of the code in the read field of the code reader.

For the relationship between camera distance and reading field size, see the section "Relationship between camera distance and reading field size".

Address Link Label

The "Address Link Label" is an additional stick-on label that is affixed to the device.

Fig.8.1: Example of an "Address Link Label"; the device type varies depending on the series

• 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.

Leuze electronic DCR 202i 44

Starting up the device – Basic configuration

• 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.

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.

8.3.4

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 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 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 received.

Ä Activate the UDP protocol. Ä Set the following values:

ð IP address of the communication partner ð Port number of the communication partner

The corresponding adjustment options can be found in the webConfig tool:

Configuration > Control > Host > Ethernet > UDP

TCP/IP

Ä Activate the TCP/IP protocol. Ä Set the TCP/IP mode of the device.

ð In 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 device determines when and with whom a connection is established.

ð In 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.

Leuze electronic DCR 202i 45

Starting up the device – Basic configuration

Ä With a device as TCP client, set the following values:

ð IP address of the TCP server, normally the IP address of the control or the host computer ð Port number of the TCP server ð Timeout for the wait time for an answer from the server ð Repetition time for renewed communication attempt following a timeout

Ä With a device as TCP server, set the following values:

ð Port 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

8.3.5

8.3.6

RS232/RS422 communication

The code reader sends an S to the interface as a start-up message and to announce that the device is ready.

The device operates as follows with the factory settings:

• Activation of the reading gate via SWI1. The integrated illumination becomes visible.

• If a code is detected, it is output via the RS232 interface according to the following protocol.

(9600baud, 8data bits, no parity, 1stop bit)

FTP client

To transfer images and log files, you can configure process data output via an FTP server.

Ä You can set the IP address and the port number of the FTP server with which communication is to oc-

cur.

Ä Assign user names and password settings or define the direction of communication using the Passive

mode option.

ð When the Passive mode option is activated, the FTP client sets up an outgoing connection to the

server.

Ä Activate the FTP client. Ä Select which images (OK/NOK) are transferred. You can assign each one a name. Ä Use the Target directory function to specify a directory relative to the root directory in which the data is

to be stored.

The corresponding adjustment options can be found in the webConfig tool:

Configuration > Control > Host > FTP client

NOTICE

Ä You can set the time stamp via Maintenance > System clock.

ð The system clock is reset if the operating voltage is interrupted.

8.4 Configuration via configuration codes

8.6.2

Control of the decoding

In general, decoding is controlled via the configurable switching inputs/outputs. The corresponding connection to the PWR/SWIO interface must be configured as a switching input for this purpose (see chapter 7.2 "PWR/SWIO – voltage supply / RS232/RS422 / switching inputs/outputs").

Controlling decoding via a switching input:

• Start/stop decoding

• Start decoding and then stop decoding after a configurable time period

• Read in a reference code

• Start automatic code type configuration (AUTO function)

• Start alignment mode

Ä Connect the required control devices, e.g., photoelectric sensor, proximity switch, etc., to the device

(see chapter 7 "Electrical connection").

Starting up the device – Basic configuration

Ä Configure the connected switching inputs according to your requirements.

ð First set the I/O mode to input. ð Then configure the switching behavior. ð webConfig tool: Configuration > Control > DigitalI/Os

NOTICE

Alternatively, depending on the camera operating mode, you can activate decoding using the+ online command and deactivate it using the– online command (see chapter 10.1 "Online commands").

8.6.3

8.6.4

Activating camera operating mode

The camera operating mode defines how the code reader starts a read process and decodes the codes if a code is located in the read field (see chapter 4.1 "Camera operating modes").

The following options are available for activating the camera operating mode:

• webConfig tool (see chapter 9 "Commissioning – Leuzeelectronic webConfig tool")

CONFIGURATION > CONTROL > Camera operating mode

• Online command via the host interface (see chapter 10.1 "Online commands")

• Trigger signal via a digital trigger input

Control of the switching outputs

By using the switching inputs/outputs of the device, external event-controlled functions can be implemented without assistance from the superior process control. Switching inputs/outputs SWO2, SWIO3 and SWIO4 on the PWR/SWIO connection must be configured as switching output for this purpose (see chapter 7.2 "PWR/SWIO – voltage supply / RS232/RS422 / switching inputs/outputs").

A switching output can, for example, be activated according to the following criteria:

• At the start/end of the reading gate

• Upon actuation by an external flash

• Depending on the read result:

• reference code comparison positive/negative

• read result valid/invalid

• Depending on the state of the device:

• Device ready/not ready

• Data transmission active/not active

• Active/standby

• Error/no error

Ä Connect the required switching outputs (see chapter 7 "Electrical connection"). Ä Configure the connected switching outputs according to your requirements.

Optimizing reading performance

Optimize the reading performance of the code reader using the following settings in the webConfig tool:

• Decoding table

Limiting of the code types being searched for and the number of digits

The adjustment options can be found in the webConfig tool: Configuration > Decoder > Code types

• Exposure time

A short exposure time enables high object speeds. Because the image brightness is thereby reduced, it may be necessary to adjust the signal gain. Image noise increases as a result, however.

The adjustment options can be found in the webConfig tool: Configuration > Image acquisition

• Image resolution

A reduced image resolution enables fast decoding. If the image resolution is reduced, the modulus size of the code that is to be read must be taken into account.

The adjustment options can be found in the webConfig tool: Configuration > Image acquisition

• Working range

Define a region of interest (ROI) to restrict coding to a single part of the image. If no region of interest is defined, the complete image is defined as the region of interest.

The adjustment options can be found in the webConfig tool: Configuration > Decoder > Region of in-

terest

• Max. decoding time

Define the maximum decoding time to limit the execution time of the code search algorithm.

The adjustment options can be found in the webConfig tool: Configuration > Decoder > Properties

• Camera operating mode

Select the Single trigger mode camera operating mode for fast complete decoding.

The adjustment options can be found in the webConfig tool: Configuration > Control > Camera oper-

ating mode

• Max. no. of codes

If the maximum number of codes to be expected in an image (ROI) is small and known, the code search is accelerated.

Define the maximum number of codes that can be decoded in a test program. If the defined number of codes has been decoded, the code search algorithm is interrupted.

The adjustment options can be found in the webConfig tool: Configuration > Decoder > Extended

• Image transfer

Deactivation of image transfer in process mode increases the decoding rate.

Adjustment options can be found in the webConfig tool: Configuration > Device > Image transfer

• Search mode

Select the Optimized search mode for fast decoding. This search mode can only be used for 2D-codes.

The adjustment options can be found in the webConfig tool: Configuration > Decoder > Extended

You must then teach the found codes using the [Optimize code] button.

• Color mode

If it is known beforehand whether the codes are printed black on a white background or white on a black background, you can select the color mode accordingly. Set the Automatic color mode if codes in both print variants are present.

The adjustment options can be found in the webConfig tool: Configuration > Decoder > Extended
