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 SSI interface:
• MS 307 connection hood with M12 connectors
• MK 307 connection hood with spring-cage terminals
• KB 307 connection hood with cable

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 mm2
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 307i
13
Device description
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 307 connection hood with M12 connectors

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 14.5 "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.
NOTICE
Only one BCB type per system!
 In a given system, use either only BCB8 with 30 mm grid or only BCB with 40 mm grid.
If different BCB types are used in one system, the BPS cannot ensure an exact position determination.
NOTICE
Configure the BPS for the used BCB type!
 The used BCB type must be set in the webConfig tool with the Tape selection parameter; see
chapter 9.3.2 "CONFIGURATION function".
 On delivery, the BPS is set for BCB with a 40 mm grid.
If the BCB8 with a 30 mm grid is used, the Tape selection must be adjusted in the BPS configuration.
 If the used BCB type does not correspond to the Tape selection configured in the BPS, exact position
determination cannot be performed by the BPS.

Control bar codes
With the help of control bar codes that are affixed on top of the bar code tape at appropriate positions, functions in the BPS can be activated or deactivated, e.g., for changing various position values at switches.
Code type Code128 with character set B is used for the control bar code.
The MVS label is a control bar code for the direction-independent switching of the position values from one
bar code tape to another in the middle of the control bar code label.
• If, upon reaching the changeover position in the middle of the MVS label, the BPS does not detect
the new BCB section in the scanning beam, the position value of the first BCB section is still output
after the middle of the MVS label for half of the label width.
The MV0 label is a control bar code for the deactivation of the position output.
• If the BPS detects the middle of the MV0 label, no position values are output after the middle of the
MV0 label.
Arrangement of the control bar codes
The control bar code is attached in such a way that it replaces one position bar code or seamlessly
connects two bar code tapes with different value ranges to one another (see figure 3.10).

 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.

Gaps in bar code tape
 Avoid polished and high-gloss surfaces.
 Keep the gaps between the two bar code tapes and the control bar code as small as possible.
Measurement value switching between two bar code tapes with different value ranges
The MVS or MV0 control bar code is used to switch between two bar code tapes.
NOTICE
1 m minimum distance of the bar code values for measurement value switching!
 For different BCB value ranges, make certain that the minimum distance of 1 m between the preceding
position bar code (before the control bar code) and the subsequent position bar code (after the control
bar code) is maintained.
Example (BCB with 40 mm grid): If the last position bar code on the BCB before the control bar code
is 75120, the following position bar code on the BCB after the control bar code must be at least 75220.
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.
Leuze electronic
BPS 307i
23
Device description
If the BPS does not detect the new BCB section upon reaching the changeover position, the position-value output is dependent on the used control bar code.
MVS control bar code: The position value of the first BCB is output beyond the middle of the MVS
label for half of the label width.
MV0 control bar code: No position values are output after the middle of the MV0 label.
• When the control label is passed, the new BCB value is output relative to the middle of the device or
label.

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.
Definition of the marker label
The following combinations of letters and numbers may be used as marker labels:
First character: A … Z, a … z
Second character: Digit from 0 … 9
Third character: Digit from 0 … 9

Twin tapes
Twin tapes are jointly manufactured bar code tapes with the same value range.
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.

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:

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 measured position and speed.
The selection of the measurement unit affects all parameters with measurement units.
Metric (mm)
or
inch (1/100 in)
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
1 mm
or
inch/100
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.

Parameter
Description
Range/Values
Integration depth
The integration depth affects the measurement of position Factory setting:
and speed. The integration depth parameter specifies the 8
number of sequential measurements that the BPS uses for
position determination.
The integration results in smoothing of the output measurement value.
An integration depth of 8 (position determination with 8
measurement values) results in a response time of 8 ms.
Update rate
The update rate (50 µs to 2 ms) of the measurement values Factory setting:
at the SSI interface can be configured via the webConfig
2 ms
tool; see chapter 9.3.2 "CONFIGURATION function".
Error delay time
Factory setting:
Errors that occur are suppressed for the configured time.
If no valid position or speed value can be ascertained in the 50 ms
configured error delay time, the last valid value is always
output.
If the error persists after the error delay time elapses, the
value of the Position/Speed value in case of error parameter is then output (standard).
Leuze webConfig tool
The webConfig configuration tool offers a graphical user interface for the display of process data, configuration and diagnostics of the BPS via a PC; see chapter 9 "Leuze electronic webConfig tool – Extended
configuration".

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.
Typical applications for the BPS include:
• High-bay storage device (see chapter 5.1)
• Telpher line (see chapter 5.2)
• Gantry cranes (see chapter 5.3)

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.
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 MVS/MV0 control bar codes (see chapter 3.4.2), the minimum distance of 1 m between the last
position bar code before the control bar code and the first position bar code after the control bar code
must be maintained.
 For bar code tapes with different value ranges, both BCBs must correspond to the BCB type configured in the BPS (see chapter 3.4.1).
 Avoid position bar code labels with the value 00000.
Measurements to the left of the center of a 00000 label produce negative position values that may not
be displayed correctly.

 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.

Mounting instructions
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 cardboard 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.
NOTICE
For parallel mounting, maintain the minimum distance!
 Maintain the minimum distance of 300 mm if you mount two BPS next to or above one another.

Switching input/output
The BPS is equipped with two, freely programmable, optically decoupled switching inputs/outputs, SWIO1
and SWIO2.
• The switching inputs can be used to activate various internal functions of the BPS (e.g., Measurement Stop/Start, Teach Preset, Reset Preset).
• The switching outputs can be used to signal the state of the BPS and to implement external functions
independent of the superior control (e.g. position value/speed value invalid, position and speed limit
value exceeded, device error).
• The control can use switching inputs/outputs as digital I/Os.
If no internal BPS function is connected to the switching inputs/outputs, the ports can be addressed
as two inputs, two outputs or as one input and one output of a digital I/O component.
The function as input or output is set via the webConfig configuration tool (CONFIGURATION >
DEVICE > Switching inputs/outputs, see chapter 9.3.2).
NOTICE
Maximum input current
 The input current of the respective switching input is maximum 8 mA.
NOTICE
Maximum loading of the switching outputs
 Do not load the respective switching output of the BPS with more than 60 mA at + 18 … 30 VDC in
normal operation.
 Each configured switching output is short-circuit proof.
The two switching inputs/outputs, SWIO1 and SWIO2, are configured as follows by default:
Switching output SWIO1: Position value invalid
Switching input SWIO2: Teach Preset
NOTICE
SWIO1 and SWIO2 as switching output
 At the outputs of the BPS (SWIO1 and SWIO2), no switching outputs may be connected from external
sensors/devices.
The switching output of the BPS may otherwise malfunction.

Basic configuration
The parameters of the SSI interface as well as the switching inputs/outputs can be configured via the
webConfig tool (see chapter 9) or via connection hood MS 307 or MK 307.
Devices with connection hood KB 307 can only be configured via the webConfig tool.
8.1
Configuring the SSI interface
8.1.1
Principal functionality of the SSI interface
Data communication of the SSI interface is based on differential transmission as is used for RS 422 interfaces. The position value is transmitted in sync with a cycle (CLOCK) specified by the control, starting with
the most significant bit (MSB); see figure 8.1.
• In the idle state, both the clock line as well as the data line are at HIGH level.
On the first HIGH-LOW edge (1), the data of the internal register are stored.
This ensures that the data are not changed during serial transfer of the value.
• With the subsequent change of the clock signal from LOW to HIGH level (2), transfer of the position
value begins with the most significant bit (MSB).
• With each subsequent change of the clock signal from LOW to HIGH level, the next least-significant bit is transmitted on the data line.
• After the least significant bit (LSB) has been output, the clock signal switches from LOW to HIGH
for one last time and the data line switches to LOW level (end of transmission).
• A monoflop retriggered by the clock signal determines how long before the SSI interface can be
called for the next transmission. This yields the minimum pause time between two successive clock
cycles (tm)
If time tm has elapsed, the data line is reset to bias level (HIGH) (3). This signals the fully completed
data exchange and renewed transmission-ready state.
• tm = 20 µs with master clock frequency 80 kHz - 800 kHz
• tm = 30 µs with master clock frequency 50 kHz - 79 kHz
• The update rate (50 µs to 2 ms) of the measurement values at the SSI interface can be configured
via the webConfig tool. Factory setting: 2 ms.
The update rate describes how quickly the data are replaced on the SSI interface by current data.
The measurement value is updated independent of the clock frequency.

SSI data transmission sequence diagram
If the off-cycle of data transmission is interrupted for longer than tm = 20 µs or tm = 30 µs , a completely new transmission cycle starts on the next cycle.
If a new transmission cycle is started before time tm elapses, the previous value is output again.
NOTICE
Factory setting: only positive position and speed values with SSI!
 In the factory setting, the SSI interface can only represent positive position and speed values.
If negative output values are ascertained due to the orientation of the BPS to the BCB or the counting
direction, the value 0 is output at the SSI interface!
In the event of a number overflow, all data bits are set to 1.

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 0, no debouncing takes place. Otherwise, the set value corresponds
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).
