3 Fast commissioning steps at a glance
Note!
Below you will find a short description for the initial commissioning of the bar code posi-
tioning system BPS 34. Detailed explanations of all listed points can be found throughout
the handbook.
Description of the BPS 34 functions
The BPS 34 uses visible red laser light to determine its position relative to the bar code tape.
This essentially takes place in three steps:
1. Reading a code on the bar code tape
2. Determining the position of the read code in the scanning area of the scanning beam
3. Calculating the position to within a millimeter using the code information and the code
position relative to the device's center.
The position value is then output via the interface.
Mechanical design
Mounting the bar code tape
The bar code tape is to be affixed without tension to a dust- and grease-free mounting
surface.
Chapter 6.3 on Page 30
Mounting the BPS 34 device
There are 2 different types of mounting arrangements for the BPS 34:
1. Using 4 M4x6 screws on the rear of the device.
2. Using a mounting device (BT 56) on the dovetail fastening grooves.

Chapter 7.1 on Page 38
Note!
During mounting, the following angles of inclination must be taken into account in the vertical
axis:
10° for a tape height of 47mm,
7° for a tape height of 30mm and
5° for a tape height of 25mm;
the working range of the reading field curve must also be taken into account.
Attention!
For the position calculation, the scanning beam of the BPS 34 must be incident on the bar
code tape without interruption. Ensure that the scanning beam is always incident on the bar
code tape when the system is moving.

5.1 MS 34 103 and MS 34 105 modular connector hoods
A modular connector hood of type MS 34 103 or MS 34 105 is part of every BPS 34. The
two connector hoods are used to connect the BPS 34 to the PROFIBUS. For this, they
feature one DP IN and one DP OUT connection each, as well as switches for address
setting.
If only the connection to the PROFIBUS is intended, type MS 34 103 is sufficient.
If, in addition, a switching input/output or modular service display are to be connected, an
MS 34 105 is required. Although switching input and output are available on the PWR IN
voltage supply connector, the switching input of the MS 34 105 has the advantage that a
standard sensor connector can be used.
5.1.1 General information
The modular connector hoods with integrated connectors are necessary accessories for
connecting a BPS 34 in a PROFIBUS system. On the MS 34 10x, the PROFIBUS is
connected, the PROFIBUS address set and the BPS 34 supplied with voltage.
MS 34 103
The MS 34 103 offers the following interfaces:
•PROFIBUS incoming DP IN
• PROFIBUS outgoing DP OUT
• Voltage supply PWR IN with switching input and switching output
MS 34 105
In addition to the MS 34 103, the MS 34 105 offers the following interfaces:
• For the MSD modular service display
• M 12 connection for switching input and switching output SW IN/OUT

5.2 MSD 1 101 modular service display
5.2.1 General information
The modular service display is used to display the calculated positions and operational data
on the one hand, and as simple access to the service interface on the other. The RS 232
service interface of the BPS 34 is located on the 9-pin sub-D connector of the MSD.
To connect the MSD 1 101 to the MS 34 105, an 8-pin cable (M12) with a length of 2m is
used (see chapter 10.3 "Accessories - Modular service display").
Using the service display, new settings for the BPS 34 can be tried quickly and easily,
without having to configure these settings via the PROFIBUS. The settings can be made via
a PC using the BPS Configuration Tool.
Once optimal settings for standard operation have been found, these must be configured in
the PROFIBUS project in order for them to become permanently active.
Note!
The BPS 34, in combination with the MS 34 10x, is equipped with an internal parameter
memory in which all configured settings are stored. When switching back from service operation to PROFIBUS operation, the settings specified in service operation are overwritten by
the settings stored in the control.
Attention!
If parameters are changed that can also be set via the PROFIBUS, they are overwritten with
the parameter setting defined in the PROFIBUS project after PROFIBUS start-up. If device
or module parameters are to be changed permanently, they must be set in the PROFIBUS
project.

6.3 Mounting the bar code tape
To prevent deposits of dirt from forming, it is recommended that the BCB be affixed vertically, possibly with a roof-like cover. If the application does not permit this, permanent
cleaning of the BCB by on-board cleaning devices such as brushes or sponges is not
permitted in any case. Permanent on-board cleaning devices polish the BCB and give it a
glossy finish. The reading quality deteriorates as a result.
Note!
When mounting the BCB, it must be ensured that neither strong sources of ambient light nor
reflections of the base on which the BCB is affixed occur in the area of the scanning beam.
The recommended interruption points on the BCB are at the provided cut marks.
Figure 6.2:Cut mark on the bar code tape
Note!
Cutting the BCB and affixing the tape so that a gap forms which is so large that a label can
no longer be reliably detected in the scanning beam results in double positions during the
position calculation of the BPS. The gap must not be greater than the distance from one cut
mark to the next (max. one label).

Figure 6.3:Gap in the cut bar code tape
30 BPS 34 Leuze electronic
Bar code tape
Procedure:
• Check the surface. It must be flat, without warping, free of grease and dust, and 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.
• Never pull the BCB. Because this is a plastic tape, forceful pulling may stretch it. This
results in a distortion of the measurement units on the tape. While the BPS 34 can
still perform the position calculation, the accuracy in this case is no longer ensured. If
the values are taught using a teach-in process, distortions are irrelevant.
• Expansion joints with widths up to several millimeters can simply be covered with the
bar code tape. The tape must not be interrupted at this spot.
• Protruding screw heads can simply be taped over. Cut out the bar code which covers
the screw head at the cut marks.
• If the application dictates the necessity of a gap, the tape is to be affixed over this gap
and the affected cut marks cut out. If the gap is small enough that the scanning beam
can detect the label to the left or to the right of the gap, measurement values are
delivered without interruption. If the scanning beam cannot completely scan any label,
the BPS 34 returns the value 0. As soon as the BPS 34 can again scan a complete
label, it calculates the next position value.
• The maximum gap between two bar code positions without affecting the measurement value is 40mm.
Note!
If the bar code tape was damaged, e.g. by falling parts, a repair kit can be downloaded from
the Internet (www.leuze.com).
Attention!
Bar code tapes with different value ranges may not directly follow one another. If the value
ranges are different, the gap between the two BCBs must be greater than the detection
range of the scanning beam or control bar codes must be used (for further information, see
also Chapter 6.4 on Page 33).
Note!
When working with the BCB in cold warehouses, it should be ensured that the BCB be
affixed before the warehouse is cooled. However, if it should be necessary to work with the
BCB at temperatures outside of the specified processing temperature, please make sure
that the bonding surface as well as the BCB are at processing temperature.
Note!
When working with BCB in curves, the BCB should only be partially cut at the cut mark and
affixed along the curve like a fan; it must also be ensured that the BCB is affixed without tension (see Figure 6.4).

Control bar code
With the aid of control bar codes, which are simply affixed over the bar code tape at the
necessary positions, functions can be activated and deactivated in the BPS 34.
Structure of the control bar codes
The control bar codes utilize code type Code128 with character set B; the position bar
codes, on the other hand, utilize Code128 with character set C. Code 128 with character set
B enables the display of all letters and numbers in the ASCII character set.
System arrangement
Bar code tape
Figure 6.5:System arrangement of control bar codes
The control bar code is affixed either within one or between two bar code tapes in such a
way that one position bar code is replaced or two bar code tapes are seamlessly connected
to one another.
Attention!
It must be ensured that only one control bar code is located in the scanning beam at any one
time. Thus, 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.

Control bar code

For error-free function, when using control bar codes it must absolutely be ensured that the
distance between the BPS and bar code tape is selected large enough. The scanning beam
of the BPS should cover three or more bar codes; this is ensured at a distance which lies in
the working range of the reading field curve.
The control bar codes are simply affixed over the existing tape. When affixing the control bar
codes, make certain to cover entire bar codes to ensure that a bar code spacing of 4cm is
maintained.

6.4.1 Controllable functions
Measurement value switching between 2 bar code tapes with different value
ranges
The "MVS" control bar code is used to switch between two bar code tapes. The end of one
tape and the start of the next can end and begin, respectively, with completely different position bar codes. If the center of the BPS 34 reaches the transition point of the control bar
code, the device switches to the second tape, provided the next position label is in its scanning beam. As a result, the output position can always be uniquely associated with one tape.

Figure 6.7:"MVS" control bar code for switching between tapes
Use of the "MVS" control bar code for switching between tapes is not dependent on direction. This means that it functions for switching from tape 1 to tape 2 and vice versa.
Figure 6.8:Switching position with the "MVS" control bar code
If the "MVS" label is passed over, the new tape value is always output relative to the center
of the device or label (see Figure 6.8). In this situation, the hysteresis of ±5mm is irrelevant.
If, however, the device is stopped within the hysteresis on the "MVS" label and the direction
changed, the starting position values have an inaccuracy ±5mm.

TNT 35/7-24V
Bar code tape
Note!
When affixing the BCB in a system in which the end of one BCB meets the start of another
BCB (position value X with position value 0), ensure that position labels 0 - 20 are not used.
This means that position label 24 must be the first label used on the continuing bar code
tape.
Note!
If only the "MVS" label is read within the scanning beam, the scanning beam must not be
interrupted during the read operation until the scanner can again read a complete position
label.
If only the "MVS" label is located in the scanning beam, the voltage on the BPS 34 must not
be switched off. Otherwise the BPS 34 will return a position value of zero when the voltage
is switched back on.
Moreover, the scanner must not be configured while in this position. Otherwise, a value of
zero is output as long as no position label is present in the scanning beam due to the fact
that the scanning beam is switched off during configuration.
6.5 Repair kit
Note!
If the bar code tape was damaged, e.g. by falling parts, a repair kit can be downloaded from
the Internet (www.leuze.com).
In these files you will find all code information for a tape with the length of 500 m within the
range of 0 … 9999.96m. 1 m of bar code tape is provided on each A4 sheet. Each meter is
divided into 5 lines of 20 cm, each with 5 code segments of information covering lengths
of 4cm each.
Procedure when replacing the defective area:
1. Determine the coding of the defective area.
2. Print out the area determined to be defective
3. Affix the printed area over the defective location

Selecting a mounting location
In order to select the right mounting location, several factors must be considered:
• The scanning range determined from the scanning curve must be adhered to at all
areas at which a position determination is to be made
• The BPS should be mounted at an angle of 10° (depending on the tape height, see
note Page 40) in the vertical axis towards the bar code tape to ensure continued reliable positioning results even the bar code tape is soiled.
• On the BPS 34, the beam is not emitted perpendicular to the cover of the housing, but
with an angle of 10° towards the top. This angle is intended to prevent total reflection
on the bar code tape. This beam exit is already integrated in the device. As a result,
the BPS can be at the minimum reading distance and mounted parallel to the bar
code tape.

8.1 PROFIBUS
8.1.1 General information
The BPS 34 with MS 34 103/MS 34 105 is designed as a PROFIBUS device (PROFIBUS
DP-V0 acc. to IEC 61784-1) with a baud rate of 12MBd. The functionality of the device is
defined via parameter sets which are clustered in modules. These modules are contained in
a GSD file. The GSD file can be downloaded from the Leuze homepage at www.leuze.com.
By using an application-specific configuration tool, such as, e.g. Simatic Manager for the
Siemens PLC, the required modules are integrated into a project during commissioning and
its settings and parameters are configured accordingly. These modules are provided by the
GSD file.
All input and output modules described in this documentation are described from the viewpoint of the control:
• Input data arrives at the control
• Output data is sent out by the control.

Attention!
Degree of protection IP 65 is achieved only if the connectors and caps are screwed into
place!
44 BPS 34 Leuze electronic
Device parameters and interfaces
Note!
For connecting DP IN and DP OUT, we recommend our ready-made PROFIBUS cables.
For further information on this topic, refer to Chapter 10.8 on Page 97.
The BPS 34 can be used in combination with an MS 34 103/MS 34 105 to branch out the
PROFIBUS network. The continuing network is connected via DP OUT.
If the PROFIBUS is not connected to another participant via the MS 34 10x, the DP OUT
connection must be fitted with a TS 02-4-SA terminator plug for the purpose of bus termination. For further information, see also Chapter 10.4 on Page 95.
Attention!
Never open the device yourself, as this may compromise degree of protection IP 65.
Before connecting the device, be sure that the supply voltage agrees with the value printed
on the name plate.
Connection of the device and cleaning must only be carried out by a qualified electrician.
The power supply unit for the generation of the supply voltage for the BPS 34 and the
respective connection units must have a secure electrical insulation through double insulation and safety transformers according to EN 60742 (corresponds to IEC 60742).
Be sure that the protective conductor is connected correctly. Fault-free operation is only
guaranteed when the device is properly earthed.
If faults cannot be cleared, the device should be switched off and protected against accidental use.
To then further isolate the error, proceed as described in Chapter 9 on Page 93.

8.1.3 PROFIBUS address
In the MS 34 103 and MS 34 105 modular connector hoods, the PROFIBUS address can be
set via two rotary switches and one slide switch.
The configuration and function of the address switches is shown in Figure 8.4.
Figure 8.4:Setting the PROFIBUS address in the MS 34 103/MS 34 105
8.1.4 General information on the GSD file
You can find the GSD file at www.leuze.com.
This file stores all the data required for the operation of the BPS 34. This data consists of
device parameters required for the operation of the BPS 34 and the definition of the control
and status bits. If parameters are changed in the project tool, for example, these changes
are stored in the project, not in the GSD file.
The GSD file is part of the device and must not be changed manually. The file is not changed
by the system either.
If the BPS 34 is operated in a PROFIBUS network, configuration must be performed exclusively via the PROFIBUS. The functionality of the BPS 34 is defined via parameter sets. The
parameters and their functions are structured in the GSD file using modules. A user-specific
configuration tool is used during PLC program creation to integrate the required modules
and configure them appropriately for their respective use.
During operation of the BPS 34 on the PROFIBUS, all parameters are set to default values.
If these parameters are not changed by the user, the device functions with the default
settings delivered by Leuze electronic. For the default settings of the BPS 34, please refer
to the following module descriptions.
Note!
A least one module in the GSD file must be activated in the configuration tool for the control,
usually the "Position value" module 1.
46 BPS 34 Leuze electronic
Note!
Some controls make available a so-called "universal module". This module must not be activated for the laser.
Attention!
The BPS 34 does not permanently store parameters changed via the PROFIBUS. Following
Power off/on, the currently configured parameters are downloaded from the PROFIBUS
manager. If no PROFIBUS manager is available following Power off/on, the BPS 34 activates its stored default settings.
8.1.5 Structure of the GSD modules
In the current version, a total of 27 modules are available for use. The modules may be
included into the project according to requirements and application.
The modules fall into the following categories:
• Parameter module for the configuration of the BPS 34.
• Status or control modules that influence the input/output data.
• Modules that may include both parameters and control or status information.
Note!
All input and output modules described in this documentation are described from the
viewpoint of the control:
Inputs (I) described are inputs of the control.
Outputs (O) described are outputs of the control.
Parameters (P) described are parameters of the GSD file in the control.
Device parameters and interfaces
Note!
At least one module must be activated to permit operation of the device at the PROFIBUS
DP.
Note!
Under some circumstances, not all 27 modules can be activated simultaneously in the configuration tool. Otherwise, the available memory for a participant may be exceeded. The
maximum available memory for a device is control dependent.

8.1.7.3 Module 3: Static preset
Note!

Description
With this module, a preset value can be defined which the BPS 34 outputs following a teach
event. Defined as a teach event is either bit 0.0 in the output data of this module or a
switching input function. After reading in the teach event, the current position value is
replaced by the preset value and the position value is now calculated and output on the basis
of the preset value. The preset remains stored in the BPS 34 and remains active even
following a new start. In order for the BPS 34 to again output the position value without the
preset, bit 0.1 in the output data must be set.
Note!
In the event of a device change, the preset value is retained in the MS 34 10x. The activation
of the preset value (preset teach) at the intended position is not necessary.

Description
With this module, a preset value can be defined which the BPS 34 outputs following a teach
event. Defined as a teach event is either bit 0.0 in the output data of this module or a
switching input function. After reading in the preset, the current position value is replaced by
the preset value and the position is now calculated and output on the basis of the preset.
The preset remains stored in the BPS 34 and remains active even following a new start. In
order for the BPS 34 to again output the tape value, bit 0.1 in the output data must be set
(preset reset). The preset value is transmitted to the BPS 34 together with the output data
of the PROFIBUS master. Thus, it can be changed during operation (dynamically).

Note!
The standby function can only be activated while in "Measure" state. This function switches
off the motor and laser. It takes approx. 2seconds to switch the BPS 34 back on (valid measurement values at the interface).
In "Idle" state, the motor continues to run. Only the laser is switched off. It takes
approx. 1second to switch the BPS 34 back on (valid measurement values at the interface).
If the start-stop event is to occur at the switching input, the "function" parameter must be
configured with the "start/stop measurement" parameter in module 7 "Switching input".

8.1.7.11 Module 11: Measurement value preparation
Description
The integration depth parameter is used to specify the number of raw position data which is
used for integration in order to determine the position value.
In order to obtain positive or negative position values depending on the direction of movement of the BPS 34, the counting direction can be selected as normal or inverted in the
output data of this module.
In order to obtain more exact measurement data while in the static state or for very slow
travel speeds, the integration depth can be increased here. If, however, a high integration
depth is used for high speeds, the contouring error is increased. With respect to contouring
errors and exact measurement data, very good results have been obtained using
8 integration steps. Using 8 integration steps, the integration time is 16ms. Thus, the
BPS 34 delivers a new position value to the interface every 2 ms which is 8ms old.

Description
The min/max position function monitors the position value and transfers the maximum/
minimum value to the PROFIBUS master.
The acquisition time can be adjusted by means of two different modes:
• The "all values" mode detects all values since the start of measurement or since a
reset event.
• The "in measurement value window only" mode only detects extreme values which
occur in the time period defined in the "MinMax period" parameter.

8.1.7.19 Module 18: Measurement error tolerance
Description
The measurement error tolerance function is used to configure a time which results in an
extended output of the last position value (module 1) in the event of an error. If the position
value changes momentarily to zero, e.g. due to a brief interruption of the laser beam, soiling
of the bar code tape or other short-term disturbances, the BPS transmits the last valid position value.
If the error disappears within the configured time, the control notices nothing or only a small
change in the position value. The availability of the system is thereby ensured. No new
values are delivered by the BPS 34, however, for a period of time extending up to the configured tolerance time. With the "delay error output" parameter, an integration error (corresponds to a missing position value) can be signaled immediately or after the tolerance time
has elapsed. If the error persists after the tolerance time has elapsed, a position value of
zero is output.

8.1.7.22 Module 21: Speed parameters
Description
The speed parameter influences the fundamental method of operation and output of the
speed measurement. The resolution, scaling, integration depth and fault tolerance for the
speed measurement can be defined.
The resolution function defines the resolution for the speed value (module 20). The scaling
function allows the speed values to be converted to any unit of measurement. To do this, the
speed value (module 20) is multiplied by the scaling factor. The speed integration depth
parameter averages the selected number of speed values to produce the speed output in
module 20.
The speed tolerance time function is used to configure a time which results in an extended
output of the last speed (module 20) in the event of an error. If the speed could not be calculated momentarily, e.g. due to a brief interruption of the scanning beam, soiling of the bar
code tape or other short-term disturbances, the BPS transmits the last valid speed. If the
error disappears within the configured time, the control notices nothing or only a small
change in the speed value. The availability of the system is thereby ensured.
The "delay speed error output" parameter can be used to signal a speed error with bit 0.0
either immediately or after the speed tolerance time in module 23 has elapsed. If the error
persists after the tolerance time has elapsed, a speed value of zero is output.

Note!

Description
The limit value function compares the current speed with a limit speed stored in the configuration. This occurs in the range defined by the range start and end. If a direction-dependent
limit value check is activated via the direction selection parameter, the values of range start
and range end define the direction. The check is always performed from range start to range
end. For example, if the range start is "5500" and the range end is "5000", the directiondependent check is only performed in the direction from "5500" to "5000". If the check is
independent of direction, the order of range start and end is without meaning. If the value is
above or below the limit value, the limit value status in module 23 is set and, if configured,
the switching output is appropriately set.

Description
The tape value correction function can be used to correct the length deviation of the bar code
tape length from the actual tape length (calibration) which results from the production
process. For this purpose, a suitable measuring device must be used to determine the actual
length of one meter of bar code tape (as printed). If, for example, one meter of tape has an
absolute value of 1001.4 millimeters, the value 10014 is entered in the "real length" parameter of this module. The real length is specified with a resolution of 0.1 millimeters. To use
the exact resolution, it is useful to measure a longer section of bar code tape and convert
the deviation to a length of one meter.
Figure 8.29:Tape value correction
The "range start" parameter must be configured according to the real starting value of the
used bar code tape. If several different bar code tapes are connected to one another in
sequence, the "range end" of the corrected tape section must also be entered. The entire
bar code tape is corrected with the default value of 10,000,000 for the range end.
