3.1.1 Image history

In Image history, the recorded images are displayed one after the other. The images recorded most recently are added on the left.

By comparing and assessing the recorded images, you can analyze, for example,

• whether the trigger is set correctly and the appropriate region of the reading area was recorded

• whether the codes for moving objects were represented in focus and whether the shutter time was set correctly

• how often a code was recorded per reading gate.

To find out the reason for unsuccessful readings, you may find it useful to analyze the

images without identified codes (N

O READ).

The images displayed in reduced form in Image history are displayed by clicking in the main view. The file name and storage location of the images are displayed as a tooltip (mouseover).

You can use the and buttons to switch between several sequences.

The number of displayed images depends on the operating mode and the configuration:

• Depending on the configuration of the Image selection parameter, either the last 200 individual images are displayed (one individual image per trigger) or 60 images per second are displayed in individual sequences.

• During reading to test the configuration (operating mode Setup), the last 30 images recorded are displayed.

3.1.2 Code infobox

The reading results are displayed in the Code infobox. To evaluate the readability and read quality, the code contents are displayed along with other relevant data for all known codes. Codes that have been detected several times in one image are listed one below the other.

The columns can be enlarged and their sequence changed using drag and drop.

Code content The contents of the codes are displayed in the C

ODE CONTENT column.

By assigning the code contents to the code, you can compare the read contents with the actual contents of the code.

ODE ID

C The code type of the code is displayed in the C

ODE ID column. By assigning the code type to

the code contents, you can activate/deactivate certain code types in the code configuration in order to limit multiple contents to one code type, for example.

Code contrast PCS The contrast of the codes in % is displayed in the C

ODE CONTRAST PCS column.

A high contrast simplifies identification of a code. By comparing different configurations, you can find the setting for the highest possible contrast.

• From 55% to 100%: Contrast

EXCELLENT

• From 20% to 55%: Contrast GOOD

• Less than 20%: Contrast POOR

Module width/height in px The module width and height of the codes is displayed in pixels in the M

IN PX column.

ODULE WIDTH/HEIGHT

The value can be used to evaluate the reading reliability (reserve) in relation to the image resolution. The higher the value, the more reliable the reading. A value of at least 2/2, is recommended, i.e. every code element is represented by at least 2/2 pixels.

By comparing the two values, you may be able to detect a distortion of the image or of the code.

4.1.1 Image history

In Image history, the recorded images are displayed one after the other. The images recorded most recently are added on the left.

By comparing and assessing the recorded images, you can analyze, for example,

• how often a code was recorded in total

• how often a code was recorded per reading gate

• whether the codes for moving objects were represented in focus and whether the shutter time was set correctly

To find out the reason for unsuccessful readings, you may find it useful to analyze the

images without identified codes (N

O READ).

The images displayed in reduced form in Image history are displayed by clicking in the main view. The file name and storage location of the images are displayed as a tooltip (mouseover).

You can use the and buttons to switch between several sequences.

The number of displayed images depends on the operating mode and the configuration:

• During reading to test the configuration (operating mode Setup), the last 30 images recorded are displayed.

4.1.2 Code infobox

The columns can be enlarged and their sequence changed using drag and drop.

ODE CONTENT

The contents of the codes are displayed in the CODE CONTENT column.

By assigning the code contents to the code, you can compare the read contents with the actual contents of the code.

ODE ID

C The code type of the code is displayed in the C

ODE ID column. By assigning the code type to

the code contents, you can activate/deactivate certain code types in the code configuration in order to limit multiple contents to one code type, for example.

Code contrast PCS The contrast of the codes in % is displayed in the C

ODE CONTRAST PCS column.

A high contrast simplifies identification of a code. By comparing different configurations, you can find the setting for the highest possible contrast.

• From 55% to 100%: Contrast

EXCELLENT

• From 20% to 55%: Contrast GOOD

• Less than 20%: Contrast POOR

Module width/height in px The module width and height of the codes is displayed in pixels in the M

IN PX column.

5 Parameters

Settings for protecting the configuration can be made on the Parameters tab. The P

ARAMETER folder in the project tree combines all available parameters.

5.1 General

Password protection for the device configuration can be activated in the General group.

Password protection ensures that only authorized users can enter device parameters. This prevents incorrect settings from being made.

5.1.1 Configuration is password protected

If this parameter is activated, access to the device configuration is password protected. To be able to change parameters, you must log in to the device at the user level of authorized customer or higher. You can use the SOPAS options, which can be found outside of the device configuration, without logging in. Password protection is activated the next time the device is restarted.

5.2 Auto setup via function button menu

The Auto setup via function button menu group contains the parameters for adjusting the auto-setup wizards.

The A

UTO-SETUP function is divided into three individual modules:

• R

EADING DISTANCE

• IMAGE SETTINGS (brightness and contrast)

• C

ODE SETTINGS (currently only available for DATA MATRIX)

The A

UTO-SETUP function can be started in different ways:

• via wizard

• via the pushbuttons on LECTOR

• by pressing the A

UTO buttons

• via command (SOPAS command)

Commands for starting the A

•

SMN MASSTART: The Auto-Setup process is started.

•

SMN MASFINISH: The Auto-Setup process is stopped and the result is transmitted. To re-

turn to reading mode, you must end the Auto-Setup process with a stop command.

•

SMN MASCANCEL: The Auto-Setup process is stopped. This does, however, cause the result

to be discarded. To return to reading mode, you must end the Auto-Setup process with a stop command.

5.4 Reading configuration

5.4.1 Camera and lighting

All parameters that affect the quality of the images taken are combined on the Camera and

lighting tab.

Optimizing the camera and lighting settings improves the contrast, sharpness and illumination. This results in better code identification and therefore increases the reliability of the reading.

A high image quality increases the time required to save the images taken. The save times can be lowered by reducing the image quality.

5.4.1.1 Reading distance

The distance between the LECTOR

Reading distance group. The reading distance is used to adapt the focal range of the LEC-

TOR

620 to the mounting site.

The value can be entered manually in mm or set automatically via the Auto button.

To avoid disruptive reflections on the object surface, the LECTOR ted on a suitable mounting bracket (see installation information).

The reading distance affects the minimum code resolution and the size of the reading area:

• If the reading distance is small, smaller codes can be read.

• A larger reading distance increases the reading area. The reduction in image brightness caused by this is compensated for by the brightness control and, if necessary, by increasing the shutter time.

Maximum reading distance with minimum resolution

Skew angle, depending on the application

should typically be tilted by 20° out of the perpendicular in relation to the surface of the code to avoid disruptive reflections.

In the case of codes created on metal, e.g., by dot peening, an angle of between 0° (bright field light) and 45° (dark field light) may be advisable.

LECTOR®620

Parameters

5.4.1.1.1 Reading distance

The Reading distance parameter is used to set the distance between the LECTOR the object. The reading distance is used to modify the depth of field of the LECTOR

620 and

620 at

the installation location.

The value can be entered manually in mm or set automatically using the Auto button.

To avoid disruptive reflections on the object surface, the LECTOR

620 should be in-

stalled at a suitable fixing bracket (see installation information).

The reading distance influences the minimum code resolution and the size of the reading area:

• If the reading distance is small, smaller codes can be read.

5.4.1.1.2 Auto

Pressing the Auto button calls up the Auto Setup wizard for automatic configuration of the reading distance.

For the reading distance to be adjusted automatically, a suitable object with contrast changes or edges (e.g. code, text, or other structures) must be placed in the reading area.

A prerequisite for automatic configuration of the reading distance is a certain basic brightness at which the structures in the image are visible.

5.4.1.2 Exposure time

The time frame for taking an image is defined in μs via the parameters for the Exposure time group.

• A short exposure time can accommodate high object speeds. As this causes the image brightness to decrease, it may be necessary to adjust the signal amplification (Exposure

time). This does, however, increase the image noise.

• A long exposure time offers a high level of brightness and therefore minimal image noise. This is the optimal setting for stationary or slow-moving objects.

5.4.1.2.1 Exposure time

The time frame for taking an image is defined in μs via the Exposure time parameter. The exposure time can be set via the slide control.

• A short exposure time can accommodate high object speeds. As this causes the image brightness to decrease, it may be necessary to adjust the signal amplification (Brightness). This does, however, increase the image noise.

• A long exposure time offers a high level of brightness and therefore minimal image noise. This is the optimal setting for stationary or slow-moving objects.

Chapter 5 ONLINE HELP SOPAS

Parameters

LECTOR®620

5.4.1.2.2 Exposure time

The time frame for taking an image is defined in μs via the Exposure time parameter. The exposure time can be entered in the input field.

• A short exposure time can accommodate high object speeds. As this causes the image brightness to decrease, it may be necessary to adjust the signal amplification (Exposure

time). This does, however, increase the image noise.

• A long exposure time offers a high level of brightness and therefore minimal image noise. This is the optimal setting for stationary or slow-moving objects.

5.4.1.3 Image settings

The image brightness and contrast settings are made via the parameters in the Image set-

tings group.

A good image that displays the code clearly is essential for a reliable reading. Optimizing the image settings results in better code identification and therefore increases the reliability of the reading.

5.4.1.3.1 Brightness

The amplification of the signal is set via the Brightness parameter. The signal amplification can be set via the slide control.

The image brightness can be adjusted by amplifying the signal in order to achieve better visibility and decodability. When setting the signal amplification, it should be noted that an overly high setting causes significant image noise and therefore makes it difficult to read the code.

For this to be avoided, the value should be increased in stages until the code can be

read successfully.

5.4.1.3.2 Brightness

The amplification of the signal is set via the Brightness parameter. The signal amplification value can be entered into the input field.

For this to be avoided, the value should be increased in stages until the code can be

read successfully.
