4 Functions

General information The integrated fieldbus connectivity = i contained in the bar code readers of the BCL 600i series facilitates

the use of identification systems which function without connection unit or gateways. The integrated fieldbus interface considerably simplifies handling. The Plug-and-Play concept enables easy networking and very simple commissioning: Directly connect the respective fieldbus and all configuration is performed with no additional software.

For decoding bar codes, the bar code readers of the BCL 600i series make available the proven CRT decoder with code reconstruction technology:

The proven code reconstruction technology (CRT) enables bar code readers of the BCL 600i 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 twist angle).

Functions

Figure 4.1: Possible bar code orientation

With the BCL 604i, configuration is generally performed with the aid of the GSD file. The device 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 device 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. Alternative activation options include online commands via the host interface and the autoReflAct function. In the basic setting, triggering takes place through an external reading cycle signal or via the PROFIBUS. An alternative option for activation is the autoReflAct function.

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 device collects additional useful pieces of data for diagnosis 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 device as well as for visualization purposes. Two LEDs provide additional optical information on the current operating state of the device.

Leuze electronic BCL 604i 19

The four freely configurable switching inputs/outputs SWIO 1 … SWIO 4 can be assigned various functions and control e.g. activation of the device or external devices, such as a PLC.

System, warning and error messages provide assistance in setup/troubleshooting during commissioning and read operation.

4.1 autoReflAct

autoReflAct st a nds 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. 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.

You will find a matching reflector in Accessories, and more are available on request.

Functions

Figure 4.2: Reflector arrangement for autoReflAct

The autoReflAct function uses the scanning beam to simulate a photoelectric sensor and thus permits an activation without additional sensors.

Leuze electronic BCL 604i 20

4.2 autoConfig

With the autoConfig function, the device 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 display, 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 device.

Afterward, bar codes with the same code type and number of digits are recognized and decoded.

The settings made via display or webConfig configuration tool push the parameters set in the Profibus only temporarily into the background. They are overwritten during integration into the Profibus or when the parameter enable is deactivated!

Device settings for operating the device on the Profibus are managed and configured exclusively by the Profibus controller (PLC). Permanent changes must be carried out here!

For further information, see chapter 10 "Starting up the device - Configuration".

5 Reading techniques

5.1 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 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

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.

Reading techniques

Figure 5.1: Deflection principle for the line scanner

5.2 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 device can also scan larger areas or spaces for bar codes. The reading field height (and the scan line length useful for evaluation) depends on the reading distance due to the optical opening angle of the oscillating mirror.

Reading techniques

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 objects.

• when the bar code is turned out of the horizontal position.

• when the reading distance is large.

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

5.3 Omnidirectional reading

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

Figure 5.3: Principle arrangement for omnidirectional reading

6 Mounting

The bar code readers can be mounted in different ways:

• Using two M4x6 screws on the rear of the device or using four M4x6 screws on the bottom of the device (see figure 3.2).

• Using a BT 56 mounting device on the two fastening grooves (see figure 14.3).

• Using a BT 59 mounting device on the two fastening grooves (see figure 14.4).

6.1 Device arrangement

6.1.1 Selecting a mounting location

In order to select the right mount

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

• The reading field of the device in relation to the bar code module width.

• The resulting minimum and maximum reading distance from the respective reading field (see chapter 14.4 "Reading field curves / optical data").

• The permissible cable lengths between the device and the host system depending on which interface is used.

• The correct time for data output. The device 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 and control panel should be very visible and accessible.

• For configuring and commissioning with the webConfig tool, the USB interface should be easily accessible.

• 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 device by mechanical collision or jammed parts.

• Possible extraneous light (no direct sunlight or sunlight reflected by the bar code).

Mounting

ing location, several factors must be considered:

With the line scanner, the beam exits the device parallel to the housing base; with the oscillating mirror, the beam exits perpendicular to the housing base. The housing base is the black surface.

The best read results are obtained when:

• The device 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.

6.1.2 Avoiding total reflection – Line scann

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 6.1)!

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!

6.1.3 Avoiding total reflection – oscillating-mirror scanner

For the device with oscillating mirror, the laser beam exits at an angle of 90° to vertical. In addition, the swivel range of ±20° is to be taken into account. This means that in order to be on the safe side and to avoid total reflection, the device with oscillating mirror

must be inclined upward or downward 20° … 30°!

6.1.4 Possible read angles between device and bar code

The optimum alignment of th

e device is accomplished when the scan line scans the code bars almost at a right angle (90°). All read angles that are possible between the scan line and bar code must be taken account (see figure 6.3).

The BCL 604i bar code readers are designed in accordance with safety class III for supply by PELV (protective extra-low voltage with reliable disconnection).

Connecting functional earth FE

 Ensure that the functional earth (FE) is connected correctly. Unimpaired operation is only guaranteed

when the functional earth is connected properly. All electrical disturbances (EMC couplings) are discharged via the functional earth connection.

Switching input/output The device is equipped with four freely programmable, opto-decoupled switching inputs and outputs

SWIO_1 … SWIO_4. The switching inputs can be used to activate various internal functions of the device (decoding,

autoConfig, …). The switching outputs can be used to signal the state of the device and to implement external functions independent of the superior control.

The two switching inputs/outputs SWIO_1 and SWIO_2 are located on the SW IN/OUT M12 socket (see chapter 7.4). The other two (SWIO_3 and SWIO_4) of the four freely configurable switching inputs/outputs are located on the PWR M12 plug.

In general, configuration of the bar code reader takes place on the PROFIBUS via the corre- sponding GSD file. Alternatively, you can temporarily set the respective function as input or out- put via the display or with the aid of the webConfig configuration tool for the purpose of testing the respective functionality. After reconnecting to the PROFIBUS or after deactivating parameter enabling, the parameter settings set by the PROFIBUS are again active!

The external wiring as switching input and switching output is described in the following. For the respective function assignment to the switching inputs/outputs see chapter 10.

Leuze electronic BCL 604i 42

Menu description

Parameter enable During normal operation parameters can only be viewed. If parameters need to be changed, the ON menu

item in the Parameter enabling menu must be activated.

Use the navigation buttons to move through the menu. Activate the desired selection with the enter button .

 In the Parameter menu, select Parameter handling.

 Press the enter button to enter the menu.

 Select the Parameter enable menu item.

 Press the enter button to enter the menu.

 Select the ON menu item.

 Press the enter button to enter the menu.

 The PWR LED lights up red. You can now set individual parameters via the display.

 Press the Escape button twice to return to the main menu.

If a password was stored, parameter enabling is not possible until this password is entered (see chapter 8.6 "Operation", Password for parameter enabling).

The device is deactivated on the PROFIBUS if parameter enabling is activated via the display. The device is reactivated on the PROFIBUS after parameter enabling is exited.

In the PROFIBUS network, configuration is performed exclusively via the PROFIBUS.

Parameters set via the display when operating the device on the PROFIBUS are overwritten by the parameters set in the GSD modules. For GSD modules which are not actively used on the PROFIBUS, the default settings of the bar code reader apply (see chapter 10.5 "Overview of the project modules"). Thus, the PROFIBUS presets values to all parameters.

If parameters are changed via the display during bus operation, the device is separated from the PROFIBUS at the moment parameter enabling is activated via the display. Parameters set by the PROFIBUS are moved to the background, and changes to parameters can be made via the display. When parameter enabling is exited, the device is automatically reconnected to the PRO- FIBUS. Upon connection to the PROFIBUS, the device receives all parameters from the PRO- FIBUS controller.

Changes made via the display are overwritten!

Device settings for operating the device on the PROFIBUS are managed and configured exclu- sively by the PROFIBUS controller.

Password for parameter enabling The password query is deactivated by default. To protect against unwanted changes, the password query

can be activated. The preset password is 0000 and can be changed as necessary . To switch on password protection, proceed as follows:

Setting the password

In order to enter the password, parameter enabling must be activated.

A selected password is saved with save.

If the password is not known, the master password 2301 can always be used to enable the de- vice.

Leuze electronic BCL 604i 43

Menu description

When operating the device on the PROFIBUS, the password entered in the display has no effect. The PROFIBUS overwrites the password with the default settings.

If a password is desired for PROFIBUS operation, it must be configured via module 62 (see chapter 10.11.3 "Module 62 – Display").

10.1 General information on the PROFIBUS implementation

10.1.1 Communication profile

The communication profile defines how participants serially transmit th medium. The device supports the communication profile for automation systems and decentral periphery

-> PROFIBUS DP.

DP communication profile The PROFIBUS DP communication profile is designed for efficient data exchange on the field level. Data

exchange with the decentral devices occurs primarily cyclically. The necessary communication functions are defined in the DP base functions. The DP optionally offers acyclic communication services as well. These are used for configuring, operating, observing and alarm handling.

In order to be able to perform data exchange, services are defined which PROFIBUS DP differentiates between on the basis of the data access points transmitted in the telegram header.

The profile of the device is based on the PROFIBUS profile for identification systems.

10.1.2 Bus-access protocol

The PROFIBUS communication profiles by layer 2 of the OSI model. The bus-access control (MAC) defines the process for specifying the point in time at which a network device can transmit data. It must ensure that no more than one participant has permission to transmit at any given time. The PROFIBUS bus-access process includes the token-passing process and the master-slave process.

Table 10.1: PROFIBUS bus-access processes

Process Description BCL 604i

Token-passing process With this process, the bus-access permission is distributed by means of a token. The

Master-slave process Various slave devices are assigned to a master. The master can address the slaves

The two processes can also be mixed in order to create a multi-master system. The device functions both in a mono-master system as well as in a multi-master system.

The device is defined as a slave in device master file (GSD file) of the BCL 604i!

10.1.4 Expanded DP functions

The PROFIBUS standard has been exp acyclic services. These services operate in parallel with the cyclic user-data communication. Masters and slaves can use additional READ and WRITE functions as well as ALARM functions. This is intended especially for operation with an engineering tool (DP-master class 2, DPM2) in order to change parameters and read out status information during normal operation.

The acyclic services operate with lower priority. The functions are different for the various master classes.

Permissible values for the PROFIBUS address are 0 … 125. Make sure that you assign a differ- ent PROFIBUS address for each PROFIBUS participant

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 10.4).

10.4 Commissioning via the PROFIBUS

10.4.1 General information

The device is designed as a PROFIBUS eter sets which are clustered in modules. The modules are included in a 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 programmable logic control by Siemens, the required modules are integrated into a project during commissioning and its settings and parameters are adjusted accordingly. These modules are provided by the GSD file.

Starting up the device - Configuration

slave device. The functionality of the device is defined via param-

Reception of the input data and sending of the output data are described from the perspective of the control (IO controller).

10.4.2 Preparing the control system for consiste

During programming the control sys

tem must be prepared for consistent data transmission. This varies from control system to control system. The following possibilities are available for the Siemens control systems.

S7 The specific function blocks SFC 14 for input data and SFC 15 for output data must be integrated in the

program. These are standard function blocks and are used to facilitate consistent data transmission.

10.4.3 General information

on the GSD file

You can find the GSD file for the respective device model at www.leuze.com. All data in modules required for operating the device is described in this file. These are input and output

data and device parameters for the functioning of the device and the definition of the control and status bits.

If parameters are changed, e.g., in the project tool, these changes are stored on the PLC side 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 manually. The file is not changed by the system either.

The functionality of the device 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 device on the PROFIBUS, 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 electronic.

For the default settings of the device, please refer to the following module descriptions.

nt data transmission

Leuze electronic BCL 604i 51

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 device!

From the perspective of the device, a distinction is made between PROFIBUS parameters and internal parameters. PROFIBUS parameters are all parameters that can be changed via the PROFIBUS 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 PROFIBUS configuration.

During the configuration phase, the device receives a parameter telegram from the master. Before this is evaluated and the respective parameter values are set, all PROFIBUS parameters are reset to default values. This ensures that the parameters of modules that are not selected are set to the default values.

This does not affect modules 1-4 for the code table extension. By default, all but the first code table entry are locked. If “no code” is selected here, all subsequent code tables are deactivated (see chapter 10.6.1 "Modules 1-4 – Code table extensions 1 to 4").

10.4.4 Permanently defined parameters/device parameters

On the PROFIBUS, parameters may be stored in modules or may be defined permanently in a PROFIBUS participant.

The permanently defined parameters are called “common” parameters or device-specific parameters, depending on the configuration tool.

These parameters must always be present. They are defined outside of the modules and are permanently anchored in the telegram header.

Starting up the device - Configuration

Hilscher master controller The fixed parameters for Slave Configuration -> Parameter Data -> Common are set in SyCon. The

module parameters are set under Slave Configuration -> Parameter Data -> Module.

Simatic S7 Controller In Simatic Manager, the permanently defined parameters are set via object properties of the device. The

module parameters are set 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 parameters that are permanently defined in the device but are configurable. These parameters always exist and are available independent of the modules.

10.5 Overview of the project modules

In the current version, a total of 56 modules are available for use. A device module (see chapter 10.4.4 "Permanently defined parameters/device parameters") is used for basic configuration of the device 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 the configuration of the device.

• Status or control modules that influence the input/output data.

• Modules that may include both parameters and control or status information.

A PROFIBUS 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 device interprets the incoming output data and triggers the appropriate reactions in the device. 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 master.

Starting up the device - Configuration

The modules can be grouped together in any order in the engineering tool. The device offers 56 different modules. Each of these modules may only be selected once; otherwise, the device ig- nores the configuration. The device checks its max. permissible number of modules. In addition, it checks the max. permissible total length (244 bytes each) of the input and output data over all selected modules. The specific limits of the individual modules of the device are declared in the GSD file.

Processing end at end of label: 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 10.15.3 "Module 92 – AutoControl"). If the parameter is not set, the bar code is immediately detected and processed further as soon as all necessary bar code elements are available.

10.7 Control modules

10.7.1 Module 10 – Activations

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 controller 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 1 byte consistent

If several bar codes are decoded in sequence without the acknowledge mode having been acti- vated, 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 - de- pendent 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 module 12 – Multi-label (see chapter 10.7.3) or one of the identifier modules (see chapter 10.10) 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 module 13 - fragmented read result (see chapter 10.7.4), 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 module 60 - device status (see chapter 10.11.1) is not deleted. For the status byte of decoding result modules 20 … 27 (see chapter 10.8.2), the two toggle bytes and the reading gate status remain unchanged.

10.7.2 Module 11 – Reading gate control

Description With the module, the reading gate control of the bar code reader can be adapted to the application. With

different parameters from the bar code reader, a time-controlled reading gate may be created. In addition, it defines the internal criteria for the reading gate end and the completeness inspection.

Output data None 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 controller. 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.

When using this module, the ACK mode should be activated (see chapter 10.7.1 "Module 10 – Activations", “Mode” parameter). Otherwise there is a risk of losing decoding results if the control is not fast enough.

10.7.4 Module 13 – Fragmented read result

Description The module defines the transfer of fragmented read results. To occupy few i/o-data, the read results may

be split into several fragments with this module. The fragments can then be transmitted one after another with a handshake.

10.8 Result Format

In the following various modules for the output of decoding results are listed. They have the same structure but different output lengths. The PROFIBUS module concept does not cater for modules of variable data length.

Modules 20 … 27 are, thus, to be regarded as alternatives and should not be used in parallel. Modules 30 … 40, on the other hand, can be combined freely with the decoding result modules.

Comparison parameter - bar code direction

Comparison parameter - scan position

Comparison parameter - oscillating mirror position

Determines how bar codes with the same content are to be managed

If this criterion has been activated, the bar code type is used to determine whether the bar codes are identical.

If this criterion has been activated, the bar code content is used to determine whether the bar codes are identical.

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 in degrees must be specified, within which the same bar code is permitted to be in the scanning beam.

If this parameter is not equal to 0, the bar code position in the swivel range of the oscillating mirror is used to determine whether identical bar codes have already been decoded. A +/bandwidth in degrees must then be specified, within which the same bar code is permitted to be in the oscillating mirror swivel range.

10.12 Switching inputs/ outputs SWIO 1 … 4

These modules define the mode of operation of the 4 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.

Starting up the device - Configuration

10.12.1Parameters for op

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) activate

the output, and the selected switch-off function(s) deactivate it again.

In example 2, the activation duration of the output is only dependent on the selected switch-on time; the switch-off signal has no effect.

Starting up the device - Configuration

Figure 10.4: Example 3: 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.

10.12.2Parameters 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.

Start-up delay td_on If th e v alue of this parameter = 0, n o s tart-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.

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.

10.15.2Module 91 – AutoReflAct (automatic reflector activation)

Description

module defines the mode of operation of the laser scanner for controlling the reading gate.

The The AutoReflAct function uses the scanning beam to simulate a photoelectric sensor and thus permits an

activation without additional sensory mechanism. This is achieved by directing the scanner with reduced scanning beam towards a reflector mounted behind the conveyor path. 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.

By means of the AutoControl function, it is possible to detect bar codes of decreasing quality and thus take appropriate measures before the label is no longer legible. With activated AutoControl function, note that the "Processing end at end of label" parameter in the CRT module should be set to allow for a better assessment of the bar code quality (see chapter 10.6.3 "Module 7 – Code reconstruction technology").
