3 Device description
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 velocity
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 posi-
tion relative to the device's center.
The position and velocity 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 PROFINET interface:
• MS 348 connection hood with M12 connectors
• MK 348 connection hood with spring-cage terminals

3.1.3 Accessories
Ideally matched accessories for the bar code positioning system:
• Highly flexible, scratch-, smudge- and UV-resistant bar code tape
• Mounting devices for precise mounting with one screw (easy-mount)
• Connection hood with M12 connectors or spring-cage terminals for modular connection technology
3.1.4 Device models with optics heating
The bar code positioning system is optionally available as a model with integrated heating. In this case,
heating is permanently installed ex works.
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 24 VDC 20%
• BPS enabling 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
Function
When the 24 VDC 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.
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 348 connection hood with M12 connectors
• MK 348 connection hood with spring-cage terminals
The voltage supply (18 … 30 V DC) is connected acc. to the connection type selected.
2 freely programmable switching inputs/switching outputs for individual adaptation to the respective appli-
cation are also available here.
3.2.1 MS 348 connection hood with M12 connectors
The MS 348 BPS connector hood features three M12 connector plugs and a Mini-B type USB socket as a
service interface for configuration and diagnostics of the BPS.
NOTICE
No self-installation of the heating!
Self-installation of the heating on-site by the user is not possible.
NOTICE
No 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.

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 14.5 „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 BCB 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 BPS configuration with the
Tape selection parameter (see
chapter 8.6.2 „DAP module – permanently defined parameters“).
On delivery, the BPS is set for BCB with a 40 mm grid.
If BCB 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.

With a standard bar code tape and a repair tape with 40 mm grid, the printed numerical values
are divisible by four without a remainder.
With a standard bar code tape and repair tape with 30 mm grid, the printed numerical values are
divisible by three without a remainder.
For bar code tapes with 30 mm grid, the designation
BCB8 is printed in plain text in addition to
the position value.

3.4.2 Control bar codes
With the help of control bar codes that are affixed on top of the bar code tape at appropriate positions, func-
tions in the BPS can be activated or deactivated, e.g., for changing various position values at switches.
MVS and MV0 are control bar codes 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.
• If, upon reaching the changeover position in the middle of the
MV0 label, the BPS does not detect
the new BCB section in the scanning beam, no position value is output after the middle of the
MV0
label.
Code type Code128 with character set B is used for the control bar code.
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 3.11).
1 Control bar code
2 The control bar code is decoded in the marked scans
Figure 3.11: Arrangement of the control bar codes
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
NOTICE
Distance between two control bar codes!
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.
Keep the gap between the BCBs that are switched between as small as possible.
