BCL 21/22 device construction

Figure 3.1: BCL 21/22 device construction

3.1 The bar code readers BCL 21/22

The bar code readers BCL 21/22 are high-speed scanners with integrated decoder for all bar codes currently in use, e.g. 2/5 Interleaved, EAN etc.

The many possible configurations allow the adaptation of the device to a multitude of reading tasks. Due to the small dimensions, the BCL 21/22 may also be used in highly constrained spaces. The low weight permits the installation into machines that were not designed for heavy components. The various beam exits (perpendicular/front side) extend the area of application of the BCL 21/22 and help it to adapt.

The connector units MA … offer simple electrical installation in conjunction with the BCL 21. Information on technical data and characteristics can be found in chapter 4.

BCL 22 "stand alone"

The bar code reader BCL 22 is operated as a "stand-alone" device on the RS 232 interface. The BCL features a cable for the electrical connection of the supply voltage, the interface, and the switching inputs.

BCL 21 with MA2/MA 4…

If several BCLs are to be networked, the use of a connector unit MA 2/MA 4… is recommended for each BCL 21 with RS 485 interface. Electrical connection, commissioning, and service can be comfortably carried out in a short period of time. BCL 21 and MA 2/MA 4… are arranged separately. The two devices are connected by a cable.

3.1.1 Networking

Up to 30 scanners can be networked via the connector unit MA 2 and a bus master MA 30/31. For this, every BCL 21 is assigned its own hardware address in the corresponding MA 2. The devices are networked by connecting the individual RS 485 interfaces in parallel.

multiNet plus

In the Leuze multiNet plus, the individual network devices sequentially transfer their data to the network master MA 30/31 when requested. In addition, every bus node declared a slave receives a device address which is adjusted in the corresponding MA 2/MA 4… via a coding switch. The device address remains in the MA 2/MA 4… when the scanner is replaced.

The master then transmits the data of all network devices via its host interface to a primary PLC control system or a computer, i.e. it "collects" the scanner data in the network and transmits them to an interface on the host computer. This reduces interface costs (CPs) and time spent programming the software.

Networking via multiNet plus

Figure 3.2: Networking possibilities using the multiNet plus (BCL 21)

10 Technical description BCL 21/22 SB Leuze electronic

Description

Two-wire RS 485

The Leuze multiNet plus is optimized for fast transmission of scanner data to a primary host computer. The multiNet plus consists physically of a two-wire RS 485 interface through which the multiNet plus software protocol is controlled. This makes wiring the network easy and inexpensive as slaves are connected to one another in parallel.

Interface modules

Shielded, twisted pair conductors should be used for the multiNet. This allows a total network length of up to 1200 m. Connection of the network to the primary computer is made via the host interface of the MA 30/31 which can be equipped with 4 different physical interface modules. The available options are modules for RS 422, RS 232, TTY or RS 485.

Fieldbus connection

The MA 2xxi connector unit (see chapter 5.1 "Accessories") is available for connecting the BCL 22 to all common fieldbus systems.

Attention!

Only operate the device in a permanently mounted fitting position. Take appropriate measures to protect the device from physical shocks and mechanical damage.

6.2.1 Device Arrangement

Selecting a mounting location

In order to select the right mounting location, several factors must be considered:

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

• the reading field of the BCL 21/22 in relation to the bar code module width

• the resulting minimum and maximum reading distance from the respective reading field

For specific information, please refer to chapter 4.4.

Notice!

The best reading results are obtained when

• the bar code is moved along the reading window at an angle of approx. 9 … 15°.

• the reading distance lies in the middle area of the reading field.

• you do not use high-gloss labels.

Application examples

Installation

Figure 6.3: Applications with perpendicular and front side beam exit

Mounting location



When selecting a mounting location, pay attention to

• 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 scanner by mechanical collision, vibrations or jammed parts.

7.1 Measures to be performed prior to the initial commissioning



Before commissioning, familiarize yourself with the operation and configuration of the device(s)!



Before switching on, recheck all connections and ensure that they have been properly made.

Configuration elements using the example of the MA 2

Figure 7.1: Configuration elements in the MA 2

Setting the device address

The device address is set in the MA 2/MA 4… using a rotary code switch. The setting is carried out as follows:



Set the device address to

• 0, if the combined BCL 21 / MA 2/MA 4… unit will not be operated in a network,

• 1…30, if several BCL 21 / MA 2/MA 4… units will be operated in a network. Each

multiNet plus network device must have a different device address assigned to it. If the MA 2/MA 4… is connected to the multiNet Master, the device combination BCL 21 with MA 2/MA 4… automatically turns into a multiNet plus slave device.

46 Technical description BCL 21/22 SB Leuze electronic

Notice!

From the hardware address, the BCL 21 detects that networking is required. With the BCL 21/22, it is possible to perform a reset using the software and the online commands. In addition, it is possible to perform a reset by switching off the supply voltage. The parameters are not lost as a result of the reset. For information on the reset commands, see chapter 9. The LED remains dark during a reset; the green LED illuminates when the device is ready for operation.

7.2 Function Test

"Power On" test

After connecting the operating voltage, the devices carry out an automatic "Power On" function test. The LED on the front side of the MA 2/MA 4…/MA 2xxi lights up. In the case of factory settings, the green LED flashes. In the additional service mode, the orange LED lights up.

Interface

Proper function of the interface can be tested easiest in service operation using the service interface with the "BCLConfig" programming software and a notebook computer. For order numbers, see chapter 5.

"Online commands"

Using the "Online" commands, important device functions can be checked, e.g. proper functioning of the laser.

Commissioning

Problems

Should problems occur during device commissioning, refer first to chapter 8.2. Should a problem persist after checking all electrical connections and settings on the devices and host, please contact a Leuze service office near you (see the back page of this operating manual).

7.3 Setting the Parameters

In the device combination BCL 21/22 with MA 2/MA 4…, two different parameter sets are managed:

•factory default parameter set

• current parameter set

Before a parameter set is loaded into the BCL 21/22 processor memory, the validity of the parameter set is checked using checksums.

Factory default parameter set

This parameter set contains the default settings made ex works for all BCL 21/22 parameters. It is permanently stored in the ROM of the BCL 21/22. The parameter set with the default settings is loaded into the memory of the BCL 21/22,

• the first time the device is commissioned after delivery

• following the command "Factory Default" in the parameterization program

• if the checksums of the current parameter set are invalid.

Current parameter set

In this parameter set, the current settings for all device parameters are stored. When the BCL 21/22 is in operation, the parameter set is stored in the EEPROM of the BCL 21/22. The current set can be stored:

• by copying a valid parameter set from the host computer

• by means of an off-line setup with the PC setup program BCLConfig

The current parameter set is loaded into the memory of the BCL 21/22,

• each time the supply voltage is connected

• following a software reset

7.3.1 Service operating mode

Setting the required parameters is carried out easiest in the 'Service' operating mode.

Service interface

By switching the operating mode switch in the MA 2/MA 4…/MA 2xxi from operation (switch in upper pos.) to service (switch in lower pos.), the connection to the host computer is interrupted and the RS 232 interface is activated. At the BCL 22, the interface is activated via a bridge between the pins 7 and 15 on the 15-pin sub-D connector.

The connector unit MA 2/MA 4…/MA 2xxi offers a service interface for commissioning the reading stations in a network. This interface can be accessed by removing the housing cover. It has a 9-pin Sub-D connector (see figure 7.1).

8.1 Display Elements

A LED labeled "SWO" is located on top of the MA 2/MA 4…. It indicates the state of the switching output 1. On the BCL 21/22, you can find LEDs that indicate different states. For detailed information regarding the state displays of the LEDs please refer to chapter 4.2.

8.2 Error Handling

Errors are indicated on the BCL 21/22 via the ERR LED. Additional error, warning and status messages are transmitted via the Host interface.

Types of errors

Errors are divided up into the following types:

•Warnings

• Serious errors

Warnings

Warnings indicate temporary operating faults which do not affect the proper functioning of the device.

Serious errors

Serious errors impair the proper functioning of the device. The device must be reinitialized.

Troubleshooting

Isolated warnings can be ignored, since the BCL 21/22 will continue to function properly.

Following a serious error, you should re-initialize the BCL 21/22. It will then usually again function properly. If a hardware problem is present, the BCL 21/22 will not reinitialize.

Warnings and errors which occur frequently can be corrected easiest using the BCLConfig software.

If you cannot correct faults and errors with the software, please contact a Leuze electronic sales office or service facility. For addresses, please refer to the back page of this operating manual.

Online commands

Alignment mode

Command ’JP’

Description This command is used for the easy mounting and alignment of the BCL 21/22. After

the function has been activated by ’JP+’, the scanner continuously supplies status information via the serial interfaces. With this online command, the scanner is set to terminate the decoding after 100 successfully decoded labels and output the status information. Subsequently, the read process is reactivated automatically. As status, the output returns the following values: scans which contain the valid label information on the basis of 100 scans, the decoding result. These values can be used to determine the decoding quality. In addition to the output of the status information, the laser beam is used to display the reading quality. Depending on how many labels were able be extracted, the duration of the laser's "off" time increases. If the reading quality is high, the laser beam flashes in brief, regular intervals. The worse the decoder decodes, the longer the pauses become during which the laser is switched off. The flashing intervals become more and more irregula r because the laser may, in total, be active for longer to extract more labels. The duration of the pauses has been stepped in such a way that they can be distinguished by the eye.

Parameter ’+’: starts the adjustment mode.

’-’: ends the adjustment mode.

Setting the laser beam at the start of the reading field

Command 'JLA'

Description Command for setting the laser beam at the start of the reading field.

It is not possible for the reading field start position to overlap the end position. There is always a small distance between the start and end.

Parameter '+' reading field start position is increased by one percent.

'-' reading field start position is decreased by one percent.

Acknowledgement The BCL does not return a response.

Setting the laser beam at the end of the reading field

Command 'JLD'

Description Command for setting the laser beam at the end of the reading field.

It is not possible for the reading field start position to overlap the end position. There is always a small distance between the start and end.

Parameter '+' reading field end position is increased by one percent.

'-' reading field end position is decreased by one percent.

11.1.6 'Online' commands for parameter handling

Requesting parameter data from the BCL

Command 'PR'

Description The PR command (ParameterblockRequest) requests parameter data from the BCL.

The <PS type> parameter indicates from which parameter set the data are to be transferred.

Parameter 'PR' <BCC type> <PS type> <Start address> <Data length> [ ; <Start address>

<Data length>]

<BCC type> Check-digit function during transfer

'0' No check digit '3' BCC mode 3 [<BCC> check digit]

<PS type> Parameter set type

'0' Current parameter set (non-volatile memory) '1' Reserved '2' Default parameter set (fixed memory)

<Start address> Parameter address (3-digits) <Data length> Number of bytes to be read out (3-digits)

The maximum data length is 123 bytes. If the HOST would like to read out more than 123 bytes, it must divide the transmission into multiple requests.

Acknowledgement 'PSx'

x: acknowledgment '1' not a valid 'Px' command '2' impermissible command length '3' impermissible value for checksum type '5' impermissible number of parameters requested '6' requested data does not (any longer) fit in the transmission buffer '7' impermissible address value '8' read access after end of parameter set '9' impermissible parameter set type

Additions Protocol:

The HOST asks the BCL to send parameter data. If the request is valid, the BCL responds with the PT command (ParameterblockTransmit) and sends the corresponding parameters. If the HOST does not receive any valid data, it must itself ensure that these data are requested again. The HOST always receives the status '0' for no further message. If an error occurs during the request, the HOST receives a negative message acknowledgment from the PS command (see the PS command).

'3' Operating values (RAM memory, lost following a reset)

76 Technical description BCL 21/22 SB Leuze electronic

Online commands

Calling up parameter status

Command 'PS'

Description The PS command (Parameter Status) acknowledges the received message and trans-

mits an acknowledgment status which indicates whether the message was valid or invalid.

Parameter 'PSx'

x: acknowledgment '0' valid transmission '1' invalid message '2' invalid length of message '3' invalid block check type '4' invalid block check checksum '5' invalid data length '6' invalid message data '7' invalid start address '8' invalid parameter set '9' invalid parameter set type

Additions Protocol:

The HOST sends parameter data and then waits for an acknowledgment message from the BCL. All faulty messages of the parameter transmissions are also acknowledged with this command.

Online commands

Transmitting parameter data to the BCL

Command 'PT'

Description The PT command (ParameterblockTransmit) transmits parameter data starting from

Parameter 'PT' <BCC type> <PS type> <Status> <Start address> <Para0H> <Para0L>

the defined address and stores them in an intermediate buffer. If the status indicates that further messages follow, these are also stored in the intermediate buffer before they are then stored under the correspond ing parameter set type in the EEPROM. The transmission can optionally occur with a block check test of the message data.

[... <Para122L>] [ ; <Start address> <Para0H> ...] [<BCC>] <BCC type> Check-digit function during transfer

'0' no check digit '3' BCC mode 3 [<BCC> check digit]

<PS type> Parameter set type

'0' current parameter set (non-volatile memory) '1' reserved '2' cefault parameter set (fixed memory) '3' operating values (RAM memory, lost following a reset)

<Mode> Parameter processing mode

'0' does not perform a reset following the write operation,

no additional parameters follow.

'1' does not perform a reset following the write operation,

additional parameters follow.

'2' performs the next reset,

no additional parameters follow.

<Start address> Parameter address (3-digits) <Data length> Number of bytes to be read out (3-digits)

The maximum data length is 123 bytes. If the HOST would like to write more than 123 bytes, it must divide the transmission into multiple messages.

Acknowledgement 'PSx'

x: acknowledgment '0' transmission valid and saved successfully '1' not a valid 'Px' '2' impermissible command length '3' impermissible value for checksum type '4' invalid received checksum '5' impermissible data length

Additions Protocol:

78 Technical description BCL 21/22 SB Leuze electronic

The HOST sends its parameters and then waits for positive acknowledgment by the BCL. If acknowledgment is negative, the process is to be repeated by the host.
