Installation procedure (overview)

Procedure for reading 2-D codes (DataMatrix):

Reading pulses via "Sensor 1" switching input (default setting)

Note In the default setting, the ICR does not read any bar codes.

Do not switch off the power supply during configuration.

1. Check the scope of delivery to ensure that it is complete.

2. Install the ICR in the reading station and align it with the stationary object with the 2-D

code (DataMatrix ECC 200) at a reading distance of 80 mm (3.15 in)(standard device). Available reading area 40 mm x 32 mm (1.58 in x 1.26 in).

3. Install the CDB 420 or CDM 420 Connection Module.

4. Connect the ICR to the CDB 420 or CDM 420 Connection Module.

5. Install the reading pulse sensor.

6. Connect the sensor to the "Sensor 1" switching input in the CDB 420 or CDM 420.

7. Connect the host to the "host interface" in the CDB 420 or CDM 420.

8. Switch on the power supply for the CDB 420 or CDM 420. Once the ICR has been started, the "Device Ready" LED lights up. The beeper beeps twice to indicate that reading mode has been started.

9. Switch on the PC and start Windows

10. Install the CLV Setup operating software and the CLV Setup Help online help software, which is supplied on the accompanying CD-ROM (“Manuals & Software“), on your PC.

11. Establish a physical connection between the PC and the Ethernet interface. To do so, connect the PC directly to the ICR by means of a crossover cable or connect the PC and ICR to the Ethernet by means of patch cables (OK = green "Ready" LED (Ethernet) lights up on the ICR)

12. Start "CLV Setup". To initiate communication, select the Ethernet interface (O

INTERFACE). CLV Setup establishes communication with the ICR (standard IP address).

13. Upload the parameter set of the ICR (displayed on the tab pages).

14. Start the CLV Assistant and carry out the following steps consecutively: C A

SSISTANT, ETHERNET ASSISTANT, SCANNER ADJUSTMENT, and DATAMATRIX AUTOSETUP.

15. To check the image online, launch the I A

DJUSTMENT step.

16. Scanner Adjustment: Represent the 2-D code statically in the red illumination field (pulsed) of the ICR. In I

MAGEFTP, make sure that the image is of a good quality in the

image memory.

17. DataMatrix AutoSetup: prepare AutoSetup and, when prompted, start the reading trigger. Represent the 2-D code statically again in the red illumination field. When doing so, retain the reading distance you adjusted previously.

18. Start DataMatrix AutoSetup. If successful, exit the Assistant after the final check. If not, repeat AutoSetup.

19. Continue configuring the ICR using the setting options on the tabs in CLV Setup (reading clock, data output). Download the modified parameter set to the ICR temporarily. Make sure that data is transferred properly to the ICR.

20. If necessary, check and optimize the set parameter values. Download the parameter set to the ICR permanently and save the parameter set as an "*.scl" configuration file in CLV Setup.

The ICR can now be operated with the application-specific settings.

(minimum requirement: Windows 95TM).

Safety information

ICR 84x Image Code Reader

2.3 General safety precautions and protection measures

¾ Read the general safety precautions carefully and observe them at all times. This also

applies to the warnings and operating instructions in the individual chapters of this document.

2.3.1 RF interferences

The ICR 84x is exclusively intended for use in an industrial environment. In case of use in residential areas, RF interference may occur.

2.3.2 Electrical installation

Risk of injury by electrical current

In the CDM 420 Connection Module, the CMP 400 Power Supply Module is connected to a mains voltage of 100 to 250 V AC/50 to 60 Hz.

¾ When working with electrical equipment, always follow the relevant safety regulations.

2.3.3 LED illumination for reading area

The ICR 84x is classified in LED class 1.

Under normal and sensible conditions, the accessible beam of the LED illumination is not hazardous. Blinding, impairment of ability to see color, or other irritations, however, cannot be excluded.

¾ The entire glass window acts as a LED outlet aperture.

¾ Caution – use of controls or adjustments or performance of procedures other than

those specified herein may result in hazardous radiation exposure.

¾ Do not open the housing.

(Opening the housing does not deactivate the laser diodes).

¾ Observe the laser protection specifications (latest version).

Radiation power

The LEDs of the illumination operate at a wavelength of λ =617nm ± 15 nm (visible red light) with a pulse duration of max. 5 ms. The energy in the human eye is < 1,7 J/m The product is classified in LED class 1 in accordance with EN 60825-1 and IEC 60825-1 (for publication date, see the warning sign on the device).

Warning labels

The warning label (Fig. 2-1, Page 2-3) in three languages is located on the wide side of the housing (see Fig. 3-1, Page 3-5).

Operating instructions Chapter 2

ICR 84x Image Code Reader

Safety information

Fig. 2-1: Black-yellow signed warning labels found on the ICR

If the ICR is installed in a machine/panel with the result that the warning labels are no longer visible, additional warnings (not included in the scope of delivery) must be provided on the machine beside the emergence aperture of the LED radiation.

Activation and deactivation of the LEDs when reading is controlled by the reading pulse (trigger source).

A timer (illumination timeout) automatically deactivates the LEDs 10 minutes (default setting) after a continuous reading pulse is initiated in Reading mode with switching input pulse modes “Sensor Input“ and “Serial Interface“. However, it does not end the reading interval. In this case, the ICR outputs the following message to the auxiliary interface:

“Illumination safety timeout“

The reading interval must be terminated by resetting the trigger signal. The LEDs activated again by the next reading pulse.

The illumination timeout can be set in the range of 1 min to 25 h or deactivated (see

Table 6-3, Page 6-25).

The Illumination LEDs are periodically activated in the operating mode “Percentage Evaluation“ and are always activated in the pulse mode “Free Running“ in Reading mode.

2.4 Quick stop and quick restart

2.4.1 Switching the ICR off

¾ Switch off the power supply or remove the ICR cable plug from the connection module.

This can result in loss of the following (at the most):

• The application-specific parameter set, if it was only stored temporarily in the ICR

• The last reading result

• Daily operating data

(operating hours counter, reading interval count, good read count, no read count, maximum duration reading interval, minimum duration reading interval, number of matches with match code 1, number of matches with match code 2, number of No Matches.)

2.4.2 Switching the ICR on again

¾ Switch on the supply voltage or reattach cable plug of the ICR to the connection module.

The ICR resumes operation with the last permanently stored parameter set and resets the daily operating data.

ICR 84x Image Code Reader

3.2 Method of operation

The ICR uses an image recording and processing system (CMOS matrix sensor with 1280 x 1024 pixels) to scan 2-D codes and bar codes with a rectangular reading area. To do so, LEDs integrated in the housing illuminate the area to be read. The LEDs generate a red illumination field (pulsed) with a configurable flash duration. To start a reading cycle, the ICR switches on the illumination. It absorbs the light reflected from the reading area (Fig. 3-2) through the lens as gray values of an image area, which are stored in an electronic image memory (image refresh rate: 25 Hz at full memory utilization). To prevent distorted images in the image buffer memory, the object with the code must remain stationary while the image is being recorded.

All dimensions in mm (in)

Fig. 3-2: Reading area of the ICR in the focus position (standard type)

The reading area (surface), which is mapped in sharp focus by the ICR in its image memory, depends on the reading distance and, depending on the resolution, must be within the reading area (DOF). Fig. 9-4, Page 9-5 shows the available reading area.

If the appropriate configuration settings are made to reduce the image buffer memory area (image geometry) used for the evaluation, this increases the potential image refresh rate. The refresh rate with the VGA resolution (640 x 480 pixels) is 60 Hz, for example. The ICR automatically adjusts the flash frequency. With a maximum of two working areas, a maximum of just two separate strips in the image field can be evaluated.

As 2-D-codes or bar codes are detected in the image data, the ICR's decoding algorithms determine the code(s) contents. At the end of the reading cycle or immediately after successful decoding, the ICR outputs the code data information via its data interface (main data interface: Host, CAN or Ethernet interface) to a host/PC for further processing.

Operating instructions Chapter 3

ICR 84x Image Code Reader

Product description

The ICR is equipped with three decoders:

• The decoder for 2-D codes

• The SMART decoder (SICK Modular Advanced Recognition Technology) for decoding

bar codes with a small aspect ratio (ratio of the code height to the code length), bar codes that are dirty or damaged, as well as bar codes that are tilted excessively (azimuth angle)

• The tried-and-tested standard decoder of the CLV series for bar codes

The ICR derives useful diagnosis data from the reading process and transfers it to the host. It also records operating data that can be requested at any time. The reading quality of bar codes can be checked in the “Percentage Evaluation“ operating mode. The reading quality of 2-D codes can be checked using the reading diagnosis data in normal Reading mode. On request, the ICR outputs the image buffer memory content as binary or grey scale bitmap via the Ethernet interface.

To start the reading process when an object is located in the reading area, the ICR requires a suitable trigger. This opens a time window (“reading interval“) in the ICR for the reading procedure. In the default setting, this trigger is supplied by an external reading pulse sensor. Alternative trigger sources include Free Running mode and a command sent via the host interface.

The current operating status is indicated by four LEDs. A beeper indicates the status of the reading result. In the default setting, the “Good Read“ function is selected for this.

If the trigger is supplied externally by a sensor, the “Sensor 1“ switching input signals the start of the reading procedure to the ICR. The “Sensor 2“ switching input is used to signal the end of reading procedure or to enter a path increment. Alternatively, it can be used e. g. to teach in a match code. The “Result 1“ and “Result 2“ switching outputs can be assigned various functions and trigger external devices, such as a PLC. Using the “Result 1“ output, an external field illumination can additionally be triggered or directly powered (max. 100 mA) by the ICR.

The ICR is operated and configured via the serial auxiliary interface (auxiliary data interface) with the user interface of the “CLV Setup“ software or via the host/auxiliary interface and command strings. Alternatively, the Ethernet interface is available for both types of operation.

The ICR outputs system and error messages as error codes, which can be requested from the error memory using command strings.

ICR 84x Image Code Reader

4.2.4 Selecting the installation site

When you select the mounting location, the distance between the ICR and the host and between the ICR and the code are important.

Distance between ICR and host

The ICR can be installed in a bus connection max. 1,200 m (3,936.96 ft) from the host. The distance which can be achieved depends on the selected model of the host interface and the set data transfer rate, however (see Table 5-5, Page 5-5). Via the Ethernet interface the ICR can connected to the Ethernet network.

Distance between the ICR and the CDB 420 or CDM 420 Connection Module

The CDB 420 or CDM 420 Connection Module must not be located further than 10 m (32.8 ft) from the ICR, since the “CLV Setup“ program on the PC accesses the auxiliary interface of the ICR via this module (RS 232) by default.

4.2.6 Distance between ICR and code

a) Basic alignment with the 2-D code/bar code

The ICR is either used with the side or front reading window, depending on the application.

Fig. 4-3 shows how the reading area is aligned with the code on the object.

ICR with side reading windowICR with front reading window

Fig. 4-3: Alignment of the ICR reading area with the code

b) Reading distance to code

The distance between the reading window of the ICR and the code is determined by the fixed focus position of the ICR and the resolution-specific depth of field for the desired cell size/module width. The distance may not exceed the total technical limits. The resolutionspecific depth of field around the focus position is shown in Chapter 9.3.2 “Reading ranges

of ICR – preliminary –“, Page 9-4 .

Fig. 4-4 shows the exact definition of the reading distance from the reading window.

The reading distance of the standard device in the focus position is 80 mm (3.15 in).

All dimensions in mm (in)

Fig. 4-4: Definition of the reading distance

Note The size of the available reading area (surface), which is mapped in sharp focus by the ICR

in its image memory, depends on the reading distance. See Fig. 9-4, Page 9-5.

Operating instructions Chapter 4

ICR 84x Image Code Reader

Installation

Angular alignment of the ICR

The alignment of the ICR is optimum when the code is in the center of the reading area (Fig. 4-3). All possible reading angles that can occur between the reading area and the code must be taken into consideration (Fig. 4-5 and Table 4-2).

Reading range

α: Azimuth angle (tilt) β: Inclination angle (pitch) γ: Rotation angle (skew)

Reading distance

Fig. 4-5: Reading angles between the reading area and the code

The following applies for bar codes and 2-D codes (DataMatrix ECC 200) when reading with omni-directional decoder:

Angle Limit value

Azimuth α (tilt) 360°

Incline β (pitch) Max. ±45° (depending on the cell size and symbol size)

Rotation γ (skew) Max. ±45° (depending on the cell size and symbol size)

Table 4-1: Permissible reading angle between the reading area and the bar code/2-D code when

reading with omni-directional decoder

The following applies for bar codes when reading with standard/SMART decoder:

Angle Limit value

Azimuth α (tilt) Max. ±45° (in scanning axis and in focus position 100 mm (3.94 in) for

module width 0.2 to 0.5 mm (7.9 to 19.7 mil))

Incline β (pitch) Max. ±45° (depending on the module width)

Rotation γ (skew) Max. ±45° (depending on the module width)

Table 4-2: Permissible reading angles between the reading area and bar code when reading with

standard/SMART decoder

Note The length of readable bar code is reduced with respect to the decodable length as a result

of the distance-dependent dimensions of the reading area (surface) (see examples in

Table 9-2, Page 9-2).

4.2.7 Count direction of the code position CP

Explanation The ICR can scan and decode several codes with each read.

In doing so, it determines the local reading diagnosis data for each code in the image memory.

Fig. 4-7 shows the count direction of the code position along the reading window.

By determining the value, the device can separate identical codes (code type, code length, and data content) and assign the code data in the reading result to its position on the object.

For 2-D codes, the ICR determines the spatial position of the finder patterns in the image memory. It outputs its corner points in the shape of two-dimensional coordinates in the reading result of the auxiliary interface as the “PT“ reading diagnosis data (see “1. Output of

reading result: 2-D code (DataMatrix ECC 200)“, Page 6-30).

For bar codes, the ICR determines the position of the first dark line of the start character in the image memory. It outputs the value in the reading result of the auxiliary interface as reading diagnosis data “CP“ (see “2. Output of reading result: Bar code“, Page 6-32).

When the ICR 840 is in the focus position (reading distance 80 mm ((3.15 in)), one pixel in the image memory is approx. 33 µ, whereby 1% of the CP is approx. 0.4 mm lengthwise of the reading area.

¾ Use screws with the correct length.

2. Screw the screws M5 through the bracket into the tapped blind holes of the ICR.

3. Tighten the screws slightly so that the ICR can to be varied in the x and y axes.

4. Place the object containing the 2-D code within the visible range of the ICR in the position at which it is to be read (with the conveyor switched off).

5. Align the ICR with the code in such a way that

– The wide side of the device with the laser warning labels is nearly parallel with the

code surface, when using a side reading window.

– The narrow side of the device with the LEDs is nearly parallel with the code surface,

when using a front reading window.

Reading distance: The reading distance of the standard device in the focus position is 80 mm (3.15 in) in front of the reading window. See Fig. 4-4, Page 4-4.

All of the possible reading angles must be taken into consideration (see Fig. 4-5,

Page 4-5).

6. If relevant to the evaluation, pay attention to the count direction of the code position if applicable (see Fig. 4-7, Page 4-6).

7. Mark the bracket of the ICR on the base (supporting stand), drill the required holes and install the bracket on the base.

5.4 Electrical installation preparations

5.4.1 Requirements for the host interface

The host interface of the ICR can be operated as an RS 422/485 or an RS 232 interface.

Table 5-5 shows the recommended maximum cable lengths as a function of the selected

data transfer rate.

Interface type Transmission rate Distance from host

RS 232 Up to 19,200 bd Max. 10 m (32.8 ft)

38,400 to 57,600 bd Max. 3 m (9.84 ft)

RS 422/485

1) with suitable line termination according to specifications

Table 5-5: Maximum cable lengths between the ICR and host

Recommendation ¾ To prevent interference, do not lay the cable parallel with power supply and motor

cables over long distances, e.g. in cable ducts.

Max. 38,400 bd Max. 1,200 m (3,937 ft)

Max. 57,600 bd Max. 500 m (1,640 ft)

5.4.2 Power supply

The ICR requires a power supply of 15 to 30 V DC (functional extra-low voltage) in accordance with the standard IEC 364-4-41. The functional extra-low voltage can be generated by using a safety isolating transformer pursuant to IEC 742. The ICR has a typical power consumption of typically 7 W, max. 10 W (when switching outputs are not connected).

The ICR is supplied with 15 to 30 V DC via the CDB 420 or CDM 420 Connection Module. If an optional CMF 400 fieldbus gateway or a CMD 400 Connection Module Display is additionally used in the CDM 420, the ICR is supplied with 18 to 30 V DC. If the CMP 400 Power Supply Module is used in the CDM 420, a mains voltage of 100 to 250 V AC/50 to 60 Hz is required.

Power-up delay

The selected device number (default setting: 1) affects the power-up delay of the device. This is useful if a large number of ICRs (e.g. in the CAN scanner network) are to be supplied from one power source. Table 5-6 contains a list of the available intervals.

5.4.3 Non-SICK power supply unit/connections without the SICK connection module

If a non-SICK power supply unit is used instead of the CDB 420 or CDM 420, it must provide a functional extra-low voltage in accordance with the standard IEC 364-4-41 and a continuous power output of at least 12 W.

The output circuit must be reliably electrically isolated from the input circuit. Do do so, use a safety isolating transformer pursuant to IEC 742.

The minimum wire cross-section for the power supply (pin 1/pin 5) must be at least

0.15 mm

(approx. 26 AWG).

¾ Use the cable no. 6 010 137 with 15-pin D-Sub HD cable socket and open end to

5.5.10 Connecting the “Result 1“ and “Result 2“ switching outputs

The two switching outputs can be assigned different functions for outputting result statuses independently of each other. If the assigned event occurs during the reading process, the corresponding switching output becomes live at the end of the reading pulse for the selected pulse duration. The pulse duration is identical for both outputs, except to the additional function of Result 1 (triggering an external illumination).

Using the “Result 1“ output, an external field illumination (powered external) can additionally be triggered or switched on when directly powered (max. 100 mA) by the ICR. The “Result 1“ output operates as low side switch, the “Result 2“ output operates as high side switch.

The “Result“ LED is linked to the “Result 2“ output and lights up in “Reading“ mode for the selected pulse duration and function of the result status display (default setting: “Good Read“, 100 ms).

Fig. 5-7 and Fig. 5-8, Page 5-16 show an example of how the switching outputs can be

connected. Table 5-12 and Table 5-12, Page 5-15 describe the characteristic data for the outputs.

Operation

6.3 Quick start

6.3.1 Starting up the ICR for test reading with the factory default setting

For simple test reading, a PC need not be connected when the ICR is operated with the factory default setting. No read result will be displayed.

Note In the default setting, the ICR only reads DataMatrix ECC 200 oodes (free symbol length,

square data field, white background).

1. Connect the ICR to the SICK CDB 420 or CDM 420 Connection Module.

2. Connect the reading pulse sensor (e.g. photoelectric reflex switch) to the “Sensor 1“ switching input of the ICR via the CDB 420 or CDM 420 (see Chapter 5.5.8 “Connecting

the “Sensor 1“ switching input“, Page 5-13).

3. Switch on the power supply to the CDB 420 or CDM 420. After the ICR has been started and has successfully completed the self-test, it outputs a tone and then two consecutive tones shortly afterwards when the Reading mode is initiated. The “Device Ready“ LED lights up. The “Result 1“ (“Device Ready“) output switches.

4. Start the reading pulse: block the light path of the photoelectric switch or close the switch. The “Laser On“ LED lights up. The ICR switches the red, pulsed illumination field on for lighting the reading area.

5. For 2-D code reading, represent the sample from Fig. 6-1 at following reading distance (no conveyor movement during reading!): ICR 840 (standard type): 80 mm (3.15 in) for side/front reading window. At this reading distance the ICR provides a reading area size of 40 mm x 32 mm (1.58 in x 1.26 in). For assigning the reading area to the reading window see Fig. 3-2,

Page 3-6).

6.3.2 Configuring the ICR for the application with the Setup Assistant

To configure the ICR with the Setup Assistant a PC must be connected to the ICR and the “CLV Setup“ software installed on the PC. To use the optional image output function of the ICR (recommended), an Ethernet connection to the ICR must be established and the “ImageFTP“ PC program (supplied with the ICR) is required.

Features of the Setup Assistant

The Setup Assistant is a separate program started from CLV Setup. It provides a step-bystep, interactive guide to configuring the ICR. The Assistant attempts to establish communication with the ICR, determine the required parameter values for reading an application-specific DataMatrix code, and transfer these values to CLV Setup for subsequent ICR parameterization (reading trigger, data output). Once communication has been established, the Assistant uploads the recent parameter values from the ICR (initial commissioning: default setting), which are also copied automatically to CLV Setup.

The Setup Assistant provides the following features:

• Connection Assistant

(Establishes the communication via the auxiliary interface or via Ethernet)

• Ethernet Assistant

(Scans the network and assigns the IP address to the ICR). The ICR images can only be output for a general reading check if communication takes place via the fast Ethernet connection.

• Scanner Adjustment

(Starts the “ImageFTP“ program for displaying the image, mapps the code in sharp focus by the ICR in its image memory)

• DataMatrix AutoSetup

(Prepares and performs AutoSetup)

• Display of the determined parameter values

(You can carry out a final check before the values are transferred to CLV Setup)

Note If the Setup Assistant is started from CLV Setup, CLV Setup is locked. When all the steps in

the Assistant have been completed or if the Assistant has been terminated, the system automatically returns to CLV Setup. If the Assistant is terminated, no parameter values will be changed in the ICR or in CLV Setup.

If DataMatrix AutoSetup has been successful, the Assistant transfers (among other things) the following parameter values permanently to the ICR and to CLV Setup (after user confirmation):

• Fixed symbol size

• Minimum cell size

• Printing procedure

• Code background

The ICR now only decodes DataMatrix codes that match the determined values.

The “ImageFTP“ program can be started in CLV Setup or in the Assistant and runs as a server under Windows, independent of the Assistant and CLV Setup.

6.4 Configuration (Parameterizing)

The ICR is configured locally in accordance with the application at hand. The read, evaluation and output characteristics can be parameterized as required. The factory default settings or an application-specific parameter set of the ICR are in effect before changes are made.

The ICR offers two configuration methods:

• Configuration via the Setup Assistant and the “CLV Setup“ program (parameter values are set via the serial interface) (see Chapter 6.3.2 “Configuring the ICR for the application with the Setup Assistant“,

Page 6-4)

• Configuration via command strings (parameter values are set via the serial interface) (see Chapter 10.5 “Configuring the ICR with command strings“, Page 10-25)

In Parameter Mode, the ICR outputs only a reading result when using the Setup Asisstant.

6.4.1 Configuring the ICR with the user interface of CLV Setup

To be able to use “CLV Setup“, a PC must be connected and the program installed on it. The procedure for connecting the PC to the ICR is described in Section Chapter 5.5.7

“Connecting the PC“, Page 5-12 respectively Chapter 5.5.6 “Connecting the Ethernet interface“, Page 5-10. Installation and startup of “CLV Setup“ and operation of the user

interface are described in the appendix (Section Chapter 10.3 “Installation and operating

instructions for the PC-based “CLV Setup“ program“, Page 10-3).

Transferring parameter sets between CLV Setup and the ICR

Upload

When the ICR is being parameterized, CLV Setup runs in the offline mode. To be able to modify the current parameter set of the ICR, this first has to be loaded to CLV Setup from the ICR. This procedure is referred to as an upload ("Upload from ICR" in the ICR 84x menu or [F3] key) during which CLV Setup always loads a complete copy of the current ICR parameter set. This parameter set remains unchanged until it is overwritten by CLV Setup.

With the help of the context menu (right mouse button), only the parameter just edited can be loaded ("Upload parameter") or from version 3.6 all parameters of one tab or one dialog box ("Upload parameters of this view") from the ICR’s memory (RAM).

Download

Changes made to the current parameter set in CLV Setup do not take effect until the parameter set has been transferred to the ICR. CLV Setup always sends a copy of the complete parameter set to the ICR, i. e. all of the existing parameter values in the ICR are overwritten. The procedure for transferring and saving the parameter values in the ICR is referred to as a download ("Download to ICR" in the ICR 84x menu or [F4] key).

With the help of the context menu (right mouse button), only the parameter just edited ("Download parameter") or from version 3.6 all parameters of one tab or one dialog box ("Download parameters of this view") will be temporarily loaded into the ICR’s memory (RAM). To finish the parametrization done by this way all parameters must be download again to the CLV with the "Permanent" option.

the ICR.

EMPORARY: CLV Setup copies the parameter set to the RAM only. The changes are

lost when the ICR power supply is switched off.

2. Confirm the dialog box with the desired save option.

The “Device Ready“ LED lights up again.

The new parameter set is stored in the ICR either permanently or temporarily dependent of the selected option.

Saving the parameter set in CLV Setup

1. To save the modified parameter set as a new configuration file in CLV Setup or to overwrite an existing file, select the menu F The S

AVE AS dialog box is then displayed.

6.5 Operating modes and outputting the reading result

The following ICR operating modes/functions can be selected in CLV Setup:

Standard operating mode

• Reading mode

For startup

• Percentage Evaluation

For adapting device to application

• Parameterizing (configuration)

(see Chapter 6.4.1 “Configuring the ICR with the user interface of CLV Setup“,

Page 6-17)

• Teach-in match code 1/activating match code comparison with “Sensor 2“ switching

input (see Chapter 10.7.1 “Triggering the Teach-in match code 1 via the “Sensor 2“

switching input“, Page 10-28).

For monitoring purposes/correcting faults

• Image acquisition (Ethernet interface)

• Displaying and editing operating data

• Reading diagnosis

• Monitor host interface

• Auxiliary input

• Self-test

• Monitor (communication between CLV Setup and ICR)

6.5.1 Reading mode (standard operating mode)

The ICR performs a self-test after it has been switched on. The start of Reading mode is confirmed with two consecutive, low tones from the beeper. In the default setting, the “Sensor 1“ switching input is the (external) trigger source of the reading pulse. The ICR only reads 2-D codes. The ICR outputs the reading result at the end of the reading pulse, in the default setting, via the host and auxiliary interfaces. Depending of the configuration, the "Result 1" and "Result 2" switching outputs become live for the predefined pulse length when defined events occur during the reading process (e. g. Good Read).

The reading result of the auxiliary interface can be displayed in the CLV Setup Terminal Emulator. For this, the auxiliary interface of the ICR must be in “Reading Diagnosis“ mode. This mode is selected for the default setting. The reading result of the auxiliary interface has a fixed, invariable format.

The data communication of the auxiliary interface can also be routed via the Ethernet interface. The physical auxiliary interface (RS 232) will then become disabled. See

Chapter 5.5.6 “Connecting the Ethernet interface“, Page 5-10.

Note For bar code reading, the corresponding bar code type must be activated for evaluation

beforehand (all bar code types are deactivated in the default setting). The length of the readable code is reduced with respect to the decodable length as a result of the distance-dependent dimensions of the reading area (surface) (see samples in

Table 9-2, Page 9-2).

The Reading mode can be called up by choosing V Emulator.

6.5.2 Percentage Evaluation

In Percentage Evaluation mode, the quality of the reading of codes which are brought statically into the reading area of the ICR is assessed (no conveyor movement).

The ICR performs 100 scans in the Free running mode and evaluates the reading quality. It outputs the reading result continuously every 2 s via the auxiliary interface. The reading results can be displayed in the Terminal Emulator of CLV Setup. The "Result 1" and "Result 2" switching outputs do not become live in the Percentage evaluation mode.

The data communication of the auxiliary interface can also be routed via the Ethernet interface. The physical auxiliary interface (RS 232) will then become disabled. See

Additional quality check of 2-D code reading

The quality of 2-D code reading can additionally be checked with the four data fields of the “EC“ reading diagnosis data. See also “1. Output of reading result: 2-D code (DataMatrix

ECC 200)“, Page 6-30.

The smaller the number of error-correction code words and weak bits which use the ICR for decoding support, the greater the code quality.

When the code quality is high enough, the evaluation time of the ICR can be optimized by selecting the corresponding parameter values in order to increase reading performance. See Chapter 10.4.2 “Optimizing reading characteristics for special applications“,

Page 10-20.

Chapter 6 Operating instructions

Operation

ICR 84x Image Code Reader

6.5.3 Image Acquisition

Depending of the configuration, the ICR tries to detect 2-D codes/bar codes in its image memory content during the decoding procedure. For reading result on Good Read, the ICR outputs the data content of the codes. To allow No Reads to be analyzed more quickly during Setup/reading mode, the ICR outputs its image memory content on request. In this way, you can simply check whether the ICR has scanned the code(s). You can also check the quality of the image in the memory. The repeated acquisition can be automated. Since large amounts of data are transferred from the ICR to the PC in a short amount of time, this function is only available on the Ethernet interface.

In the default setting, the Image Acquisition is disabled. Image Acquisition for 2-D codes, however, runs via the Setup Assistant (DataMatrix AutoSetup and ImageFTP). The settings used here by the ICR are described in Section “Output criteria during using the Scanner

Adjustment and the DataMatrix AutoSetup:“, Page 6-11.

Prerequisistes For the Image Acquisition and the image output in reading mode the following are required:

• Data connection between ICR and the PC via Ethernet

• The ICR is defined as an FTP client

• Correct server address (PC)

• “ImageFTP“ program (server) running on the PC

• Defined image acquisition criteria (cyclical or by conditions in the reading procdure)

When requested, the ICR transfers the image memory content to the PC either as greyscale bitmap (BMP), as a graphical file (JPEG) or as a run length coded binary bitmap (bar codes). The image quality can be selected (BMP: scaling, JPEG: quality). The ICR can also transfer reading diagnosis data in XML files. ImageFTP displays this data as colored lines in the greyscale bitmaps or JPEGs.

The ICR outputs the image either with each reading pulse or in compliance with a selectable condition (e. g. Good Read, No Read etc.). The file name generation procedure can be set.

Preparing the Image Acquisition

1. If you have not already done, connect the PC to the ICR via the Ethernet (see Chapter

5.5.6 Connecting the Ethernet interface, Page 5-10).

The green “Ready“ LED at the RJ-45 socket of the ICR lights up when the physical connection has been successfully established.

Fig. 6-30: CLV Setup: Output of the reading result of the host interface in the Terminal Emulator (in

this case: O = Output)

Note Large amounts of data received at high speeds via the host interface and high data transfer

rates may cause the flow of host interface traffic to no longer be completely displayed on the auxiliary interface (display “ … “). This is caused by the slower data transfer speed of the auxiliary interface (9,600 bd).

In the default setting, the ICR sends the following in the data output string of the host interface:

• Good Read: data contents of the code

• No Read: NOREAD string

The “Header“ and “Terminator“ blocks are empty, the code contents are not separated by reading diagnosis data and/or constants.

Tip

The structure of the data output string of the host interface can be configured via the D

ATA STRINGS tab:

Up to 10 elements, consisting of constants (letters, digits, control characters) and/or reading diagnosis data, can be entered in the "Header", "Reading data" and "Terminator" blocks.

1. Choose the D

2. Click the H The dialog window E

6. The constants or placeholders for reading diagnosis data can be placed freely before or after the code contents in the R

EADING DATA field. The selected arrangement is the

same for all output code contents.

7. Perform a download to the ICR. This is done by clicking in the toolbar. The D

OWNLOAD PARAMETER dialog box is displayed.

8. Confirm the dialog box by selecting the P

ERMANENT save option.

The ICR outputs the selected elements in the data output string of the host interface with the next reading result.

6.5.7 Auxiliary input

Function of the auxiliary interface. In this mode, the ICR accepts a code input to the auxiliary interface (via keyboard or hand scanner with decoder). It sends the code to the host in a separate data string via its host interface. No Reads can, therefore, be corrected by transmitting missing codes subsequently.

Chapter 10.7.2 “Auxiliary input via the auxiliary interface“, Page 10-34 describes this

function and the associated procedure in greater detail.

6.5.8 Self-test

After the ICR has been switched on, it performs a self-test before it is initialized with the parameter set. The test can be called up explicitly at any time via CLV Setup. During the selftest, the ICR checks that its hardware components are functioning correctly. A final message via the auxiliary interface provides information on the test result. The ICR does not output a reading result during the test routine.

1. Click in the toolbar. The Terminal Emulator window is then displayed. The ICR is in Reading mode.

2. Click S

ELF TEST under DEVICE MODE.

The “Device Ready“ LED is extinguished. The ICR cancels the Reading mode and starts the test routine. After a few seconds, the ICR outputs the encoded test result in the form of a code number (Fig. 6-31, Page 6-43).

3. To return to Reading mode, click the READING MODE radio button or close the Terminal Emulator. The ICR returns to Reading mode. The “Device Ready“ LED lights up.

The code number “1500“ means that the self-test was completed successfully and that no faults were diagnosed.

6.5.9 Performing device functions of ICR in the dialog box

CLV Setup enables a number of ICR functions to be executed interactively. CLV Setup prompts the user to carry out specific actions and provides information on the progress of the function being executed.

The following functions are available:

• Match code Teach-in

• Analyze scanner network (only if the CAN interface is used)

• Activate factory defaults in device

¾ In the menu bar, select the desired function from ICR 84

X, DEVICE FUNCTIONS.

– or –

Press the [F2] key. The D

EVICE FUNCTIONS dialog box is then displayed.

Select the desired function from the E

XECUTE menu.

CLV Setup starts the function and, where appropriate, prompts the user to carry out the necessary actions.

6.6 ICR messages

The ICR outputs encoded system and error messages via the terminal interface to report user actions or events in the reading process. When the system is started, the ICR also outputs system messages in plain text (English). If configured accordingly, the ICR transfers the error status ST in the data output string of the host interface.

6.6.1 Displaying messages

In the 4th field from the left in the status bar at the bottom of the screen, CLV Setup displays system and error messages that occur at the terminal interface of the ICR. These are recorded in a file, which is continuously updated. The messages have the following format:

• System message: "ICR SYS-Message: xxx"

• Error message: "ICR SYS-Error: 048ID8xxx"

The additional system messages in plain text can be displayed in the terminal emulator if CLV Setup and the terminal emulator are started before the ICR is connected.

Additional system messages:

When the system is started, these system messages inform the user whether the starting process was successful. No further measures are normally required. Fig. 6-33 shows an example.

6.6.2 Error messages

Error messages indicate the following types of error:

• a device defect

• incorrect parameter settings

• errors during data transmission to the host

Table 8-3, Page 8-5 lists the messages with the associated corrective measures.

Note To call up the most recent error to occur in the CLV, enter command "2?SF" in the command

line of the terminal emulator.

6.7 Switching the ICR off

1. If the parameter set was modified in CLV Setup or was only stored temporarily in ICR via a download (“Temporary“ option or via context menu (right mouse button)), the parameter set must be stored permanently in the ICR by choosing the P storage option.

2. Save parameter set as a “*.scl“ configuration file in CLV Setup.

3. Switch off the power supply of the CDB 420 or CDM 420 or pull the plug of the ICR from the connection module.

The last parameter set stored permanently in the ICR remains valid.

ERMANENT

Archiving the parameter set:

We recommend that you print out the configuration file in order to archive the parameter set.

1. Click in the toolbar. The P

RINT FILE dialog box is then displayed.

2. Enter a comment in the input field to assign the printout to the ICR. Confirm the dialog box with “OK“. The P

RINT dialog box for configuring the printer is then displayed.

3. Edit the dialog box accordingly and confirm. CLV Setup prints out the current configuration file in the form of a table.
