3.1 Device overview

3.1.1 General information

The BPS bar code positioning system uses visible red laser light to determine its position and its speed value relative to a bar code tape that is affixed along the travel path. This takes place in the following steps:

• Read a code on the bar code tape (see figure 3.1)

• Determine the position of the read code in the scanning beam

• Calculate the position to within less than a millimeter using the code information and the code position relative to the device's center.

The position and speed values are then output to the controller via the host interface. The BPS consists of device housing and interface connection hood for the connection to the control. The

BPS can optionally be delivered with display and optics heating.

The following connection hoods are available for the connection of the RS 485 interface:

• MS 301 connection hood with M12 connectors

• MK 301 connection hood with spring-cage terminals

• KB 301 connection hood with cable

3.1.2 Performance characteristics

The most important performance characteristics of the bar code positioning system:

• Positioning with submillimeter accuracy from 0 to 10,000 m

• For the control at high traverse rates of up to 10 m/s

• Simultaneous position and speed measurement

• Working range: 50 to 170 mm; enables flexible mounting positions

• Interfaces: PROFINET fieldbus, PROFIBUS fieldbus, SSI, RS 232/RS 422, RS 485

• Binary inputs and outputs for control and process monitoring

• Configuration via webConfig tool or fieldbus

• Diagnostics via webConfig tool or optional display

• Optional model with display

• Optional model with heating for use to -35 °C

3.1.3 Accessories

Special accessories are available for the bar code positioning system. The accessories are optimally matched to the BPS:

• Highly flexible, scratch-, smudge- and UV-resistant bar code tape

• Mounting devices for precise mounting with one screw (easy-mount)

• Modular connection technology via connection hoods with M12 connectors, spring-cage terminals or with cable.

Device description

3.1.4 Device model with heating

The bar code positioning system is optionally available as a model with integrated heating. In this case, heating is permanently installed ex works.

NOTICE

No self-installation of the heating!

 Self-installation of the heating on-site by the user is not possible.

The heating consists of two parts:

• Front cover heater

• Housing heater

Features of the integrated heating:

• Extends the application range of the BPS to -35 °C

• Supply voltage 18 … 30 VDC

• BPS release through an internal temperature switch (start-up delay of about 30 min for 24 V DC and minimum ambient temperature of -35 °C)

• Required conductor cross-section for the power supply: At least 0.75 mm

NOTICE

Do not use ready-made cables!

 It is not possible to use ready-made cables.

The current consumption of the BPS is too high for the ready-made cables.

Function When the supply voltage is applied to the BPS, a temperature switch initially only supplies the heating with

current (front cover heater and housing heater). During the heating phase (around 30 min), when the inside temperature rises above 15 °C, the temperature switch connects the BPS to the supply voltage. This is followed by the self test and the changeover to read operation. The PWR LED lights up, showing overall readiness for operation.

Leuze electronic BPS 301i 13

When the inside temperature reaches approx. 18 °C, another temperature switch turns the housing heater

off and, if necessary, back on again (if the inside temperature drops below 15 °C). This does not interrupt the read operation.

The front cover heater remains activated until an inside temperature of 25 °C is reached. At temperatures above this, the front cover heater switches off and, with a switching hysteresis of 3 °C, back on again at an inside temperature below 22 °C.

3.2 Connection technology

For the electrical connection of the BPS, the following connection variants are available:

• MS 301 connection hood with M12 connectors

• MK 301 connection hood with spring-cage terminals

• KB 301 connection hood with cable

The voltage supply (18 … 30 VDC) is connected acc. to the connection type selected. Two freely programmable switching inputs/switching outputs for individual adaptation to the respective

application are also available here.

3.2.1 MS 301 connection hood with M12 connectors

3.4 Bar code tape

3.4.1 General information

The bar code tape is available in different variants:

• BCB bar code tape with 40 mm grid Code128 with character set C, increasing in increments of 4 (e.g., 000004, 000008, … )

• Bar code tape BCB8 with 30 mm grid Code128 with character set C, increasing in increments of 3 (e.g. 000003, 000006, … )

A bar code tape consists of a sequence of individual position labels in one of the two grids. Defined cut marks are provided for cutting the BCB.

The bar code tape is delivered on a roll. A roll contains up to 200 m of BCB, with the wrapping direction from the outside to the inside (smallest number on the outside). If more than 200 m of BCB is ordered, the total length is divided into rolls of 200 m.

Bar code tapes with special requirements with respect to height, length and value range can be ordered from Leuze electronic (see chapter 14.6 "Bar code tapes").

NOTICE

Value range for BCB with special requirements!

 When ordering bar code tapes with special requirements, make certain that the value range contains

only values that are divisible by three (BCB8 with 30 mm grid) or four (BCB with 40 mm grid).

It may otherwise not be possible to purchase and use repair tapes.

 Make certain that there is only one control bar code (or marker label) in the scanning beam at a time.

The minimum distance between two control bar codes is determined by the distance between the BPS and bar code tape and the resulting length of the scanning beam.

The control bar codes are simply affixed over the existing bar code tape. A control bar code should cover an entire position bar code and must have the correct grid dimension (see

figure 3.12):

• 30 mm with BCB8 bar code tapes

• 40 mm with BCB bar code tapes

Keep the gap between the BCBs that are switched between as small as possible.

If the minimum distance between the bar code values is not maintained, position determination may be faulty.

• The end of the preceding bar code tape and the start of the subsequent bar code tape can end and begin, respectively, with completely different position bar codes.

• BCB changeover by means of a control bar code always occurs at the same position, i.e., it serves to change from the preceding tape to the subsequent tape and vice versa.

• If the center of the BPS reaches the transition point of the control bar code, the device switches to the second BCB, provided the next position label is in the BPS's scanning beam (see figure 3.13). The output position value is thereby always uniquely assigned to one BCB.

3.4.3 Marker labels

Marker labels, which are affixed at the appropriate locations on top of the bar code tape, can be used to trigger various functions in the superior control. The BPS detects the defined marker labels in the scanning beam, decodes them, and makes them available to the control.

NOTICE

Distance between two marker labels!

 Make certain that there is only one marker label (or control bar code) in the scanning beam at a time.

The minimum distance between two marker labels is determined by the distance between the BPS and bar code tape and the resulting length of the scanning beam.

NOTICE

A twin tape always consists of two bar code tapes!

 When ordering a twin tape, two bar code tapes are always included with an order.

Twin tapes are used if positioning with two bar code tapes is necessary, e.g., with crane systems or elevators.

Because they are manufactured jointly, both tapes have the same length tolerance. As a result, differences in length and code position are minimal. By having the same code position on both tapes, improved synchronization can be achieved during positioning compared to bar code tapes that are manufactured separately.

4 Functions

This chapter describes the functions of the BPS and the parameters for adaptation to the respective application conditions and requirements.

The parameters are set via the webConfig tool; see chapter 9 "Leuze electronic webConfig tool – Extended configuration".

Main functions:

• Position measurement

• Speed measurement

The following parameters are relevant for the timing of the position and speed measurement:

• Measurement value preparation Configurable response time

• Measurement error tolerance Configurable time-based error suppression

4.1 Position measurement

The output value of the position measurement is calculated from the measurement and the settings for resolution, preset, offset, etc.

The most important individual parameters for the position measurement are:

Functions

Parameter Description Range/Values

Position resolution The parameter specifies the resolution of the position value.

It acts only on the host interface. The resolution has no effect on the set parameter values such as offset or preset.

Unit The parameter specifies the measurement unit of the mea-

sured position and speed. The selection of the measurement unit affects all parameters with measurement units.

Offset The offset is used to correct the position value by a fixed

amount. If the offset is activated, the offset is added to the position value. This yields a new output value: Output value = position value + offset

Preset Like the offset, the preset is used to correct the position

value. With preset, a preset value is specified. The value is accepted during a corresponding event (switching input or fieldbus). If the preset is activated, this has priority over the offset.

5 Applications

Wherever systems are moved automatically, it is necessary to uniquely determine their respective positions. In addition to mechanical measuring sensors, optical methods are particularly well suited for position determination as they can be used to determine position without mechanical wear and slippage.

Compared to common optical measurement techniques, the Leuze electronic Bar code Positioning System (BPS) is able to measure a position with absolute sub-millimeter accuracy, i.e. independent of reference points. As a result, it is able to provide a unique position value at any time. With the highly flexible and hard-wearing Bar Code Tape (BCB), the system can even be used without problem in systems with curves or guide tolerances. And this at lengths of up to 10,000 meters.

The product family of Leuze electronic bar code positioning systems convinces with a variety of advantages:

• The laser simultaneously scans three bar codes and, as a result, is able to determine the position with sub-millimeter accuracy. The wide reading field makes accurate position determination possible even in the event of minor damage to the tape.

• With the systems' flexible depth of field, it is also possible to bridge over mechanical deviations.

• Due to the large reading distance combined with the great depth of field, a large opening angle and a very compact construction, the device is ideally suited for the conveyor and storage technology market.

• The BPS devices are capable of simultaneously measuring position and speed and are thus also suitable for control tasks in your automation applications.

• Using a mounting device, the BPS can be mounted with millimeter accuracy with just one screw. If mounted using a mounting device, a new device is automatically aligned correctly should it be necessary to exchange a device (easy-mount).

• The unique labeling of the bar code tape allows the system to be put back into operation without problem even after a brief voltage drop without, e.g., needing to utilize a reference point.

• The Leuze electronic bar code tape is very robust, highly flexible and, thanks to the self-adhesive back, can be easily integrated into your overall mechanical system. It can be fit optimally to both vertical as well as horizontal curved paths and thereby reliably facilitates trouble-free and reproducible measurement at any point in your system with sub-millimeter accuracy.

Applications

Typical applications for the BPS include:

• High-bay storage device (see chapter 5.1)

• Telpher line (see chapter 5.2)

6.1.1 Installation and application remarks

NOTICE

BCB mounting

 When processing BCBs, observe the specified processing temperatures.

When processing BCBs in cold storage facilities, the BCB must be affixed before cooling the storage facility.

However, if it should be necessary to affix the BCB at temperatures outside of the specified processing temperature, assure that the bonding surface as well as the BCB are at the processing temperature.

 Avoid dirt deposits on the BCB.

If possible, affix the BCB vertically.

If possible, affix the BCB below an overhead covering.

The BCB must never be continuously cleaned by on-board cleaning devices such as brushes or sponges. Permanent on-board cleaning devices polish the BCB and give it a glossy finish. The reading quality deteriorates as a result.

 After affixing the BCBs, make certain that there are no polished, high-gloss surfaces in the scanning

beam (e.g., glossy metal at gaps between the individual BCBs), as the measurement quality of the BPS may be impaired.

Affix the BCBs to a diffusely reflective support, e.g., a painted surface.

 Avoid sources of extraneous light and reflections on the BCB.

Ensure that neither strong sources of extraneous light nor reflections of the support on which the BCB is affixed occur in the vicinity of the BPS scanning beam.

 Affix the BCB over expansion joints up to a width of several millimeters.

The BCB must not be interrupted at this location.

 Cover protruding screw heads with the BCB.

 Ensure that the BCB is affixed without tension.

The BCB is a plastic tape that can be stretched by strong mechanical tension. Excessive mechanical stretching results in lengthening of the tape and distortion of the position values.

Mounting and installation

NOTICE

BCB application

 Make certain that the BCB is located in the scanning beam of the BPS over the entire traversing path.

The BPS can determine the position on BCBs with arbitrary orientation.

 Bar code tapes with different value ranges may not directly follow one another.

In the case of different value ranges, a gap of at least 1 m must be maintained between the last position bar code of the preceding BCB and the first position bar code of the subsequent BCB (see chapter 3.4.2).

 For

NOTICE

Avoid cutting BCB!

 If possible, avoid cutting bar code tapes.

Optimum position value determination by the BPS is achieved with continuously affixed BCB.

 If there are mechanical gaps, first affix the BCB continuously. Then cut the BCB.

NOTICE

No glossy gaps in the cut bar code tape!

 Ensure that there are matt, bright surfaces behind the gaps in the BCB.

Polished, reflective, and high-gloss surfaces in the scanning beam may impair the measurement quality of the BPS.

6.1.3 Mounting the BCB

Mount the BCB as follows:

 Check the surface.

It must be flat, free of grease and dust, and be dry.

 Define a reference edge (e.g., metal edge of the busbar).

 Remove the backing and affix the BCB along the reference edge tension free.

 Secure the bar code tape to the mounting surface by pressing down with the palm of your hand.

When affixing, make certain that the BCB is free of folds and creases and that no air pockets form.

NOTICE

When mounting, do not pull on the BCB!

 The BCB is a plastic tape that can be stretched by strong mechanical tension. The stretching results

in lengthening of the tape and distortion of the position values on the BCB.

While the BPS can still perform the position calculation in the event of distortions, the absolute measurement accuracy is no longer ensured in this case. If the values are taught using a teach-in process, stretching of the BCB is irrelevant.

If a bar code tape was damaged, e.g., by falling parts, you can download a repair kit for the BCB from the Internet (see chapter 11.2.2 "BCB repair with repair kit").

Use the bar code tape created with the repair kit only temporarily as an emergency solution.

A twin tape always consists of two bar code tapes.

 When ordering twin tapes, two bar code tapes are always included with an order.

 Ensure that the BCB is affixed without tension.

The BCB is a plastic tape that can be stretched by strong mechanical tension. Excessive mechanical stretching results in lengthening of the tape and distortion of the position values.

Mounting two bar code tapes with the same value range For crane systems or elevators, two bar code tapes with the same value range are used for positioning.

If two bar code tapes with the same value range are needed, the use of twin tapes is recom- mended (see chapter 3.4.4 "Twin tapes").

If a twin tape is not used: To have the same values at the same position, one bar code tape must be affixed with numbers upside down while the other is affixed normally (see figure 6.7).

300 mm

NOTICE

Select the mounting location.

 Make certain that the required environmental conditions (humidity, temperature) are maintained.

 Make certain that the distance between BPS and bar code tape is sufficiently large.

The scanning beam of the BPS should cover three or more bar codes.

The distance between BPS and bar code tape must be in the working range of the reading field curve.

 Make certain that the exit window does not become soiled, e.g., by leaking liquids, abrasion from card-

board packaging or residues from packaging material.

 Mounting the BPS outdoors or with BPS with integrated heating:

Mount the BPS in a way which provides maximum thermal isolation, e.g., using rubber-bonded metal.

Mount the BPS so that it is protected from airflow, e.g., in a protective housing.

 Mounting the BPS in a protective housing:

When installing the BPS in a protective housing, ensure that the scanning beam can exit the protective housing without obstruction.

 Make certain that the scanning range determined from the scanning curve is adhered to at all locations

where a position determination is to be made.

 Ensure that the scanning beam is always incident on the BCB when the system is moving.

For the position calculation, the scanning beam of the BPS must be incident on the BCB without interruption.

For the best functionality, the BPS must be guided parallel to the BCB. It is not permitted to move outside of the approved working range of the BPS (50 … 170 mm) while the system is in motion.

 Make certain that there is only one control bar code (or marker label) in the scanning beam at a time.

The minimum distance between two control bar codes is determined by the distance between the BPS and bar code tape and the resulting length of the scanning beam.

8.7 Communication protocol (RS binary protocol)

The RS binary protocol consists of three bytes of request telegram and seven or nine bytes of response telegram.

Request telegram The request for transmitting the measured positions or the speed is controlled via a request telegram that

is three bytes long. The BPS processes the three bytes of the request telegram, checks the XOR link and executes the func-

tion specified in the command byte.

The XOR checksum is entered by the sender (control) in the request protocol and checked by the receiver (BPS). A protocol is correctly transferred if the XOR checksum of the transmitter and the XOR checksum of the receiver are the same. If the XOR comparison is negative (different checksums), the protocol is not accepted by the BPS. The BPS does not send acknowledgment for an unequal checksum.

Response telegram for commands 0xF1 to 0xF6 and 0xFA to 0xFC In the response telegram to commands 0xF1 to 0xF6 and 0xFA to 0xFC, the BPS transfers the available

status information and the requested data in a seven-byte length. For commands 0xFA to 0xFC, the response only contains three bytes of user data, i.e., byte 2 is always

transferred with 0x00 and the user data is located in byte 3 to byte 5.

Timing functions of the switching inputs/outputs The timing functions (e.g., start-up delay) can only be configured with the webConfig tool.

• Start-up delay With this setting, the output pulse is 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. If the output is 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.

• 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 this parameter has the value to the time (in ms) that the input signal must be present and stable.

• Switch-off delay This parameter specifies the duration of the switch-off delay (in ms).
