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 PROFINET interface:

• MS 348 connection hood with M12 connectors

• MK 348 connection hood with spring-cage terminals

• ME 348 103 connection hood with cables with M12 connector

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 cables

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 348i 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 348 connection hood with M12 connectors

• MK 348 connection hood with spring-cage terminals

• ME 348 103 connection hood with cables with M12 connector

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.

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

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 3.16). The output position value is thereby always uniquely assigned to one BCB.

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.

Twin tapes are always delivered in pairs on two rolls.

If twin tapes are replaced, both tapes are to be replaced.

Twin tapes can be ordered from Leuze electronic (see chapter 14.5 "Bar code tapes").

4 Functions

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

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:

Parameter Description Range/Values

Functions

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

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.

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.

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 an input or output is set via PROFINET parameters (see chapter 8.4) or using the webConfig configuration tool (CONFIGURATION > DEVICE > Switching inputs/outputs, (see chapter 9.3.2).

If SWIO1 or SWIO2 is to be used as digital input or output, the configuration must be performed in module 4 (see chapter 8.4.6) or module 5 (see chapter 8.4.7).

7.6.2 Linear topology

The integrated switch functionality of the BPS offers the possibility to network multiple BPS devices. In addition to the classic "star topology", a "linear topology" is thus also possible. The wiring of the network in a linear topology is simple and economical since the network connection is looped through from one participant to the next. The maximum length of a segment (connection from one participant to the next) is limited to 100 m.

8.1 Configuring the PROFINET interface

The BPS is designed as a PROFINET-RT device (Real Time; acc. to IEEE 802.3). It supports a transmission rate of up to 100 Mbit/s (100 Base TX/FX), full duplex, as well as auto-negotiation and auto-crossover.

• The functionality of the BPS is defined via parameters which are organized in modules. The modules are part of the Generic Station Description Markup Language (GSDML) file.

• Each BPS has a unique MAC address (Media Access Control) that is specified on the name plate. The MAC address (MAC-ID) is linked to an IP address during the course of configuration.

• The Simatic Manager for creation of PROFINET networks links the IP address to a freely selectable device name which may only exist once in the network.

Address Link Label The “Address Link Label” is an additional stick-on label that is affixed to the device.

Figure 8.1: Example of an “Address Link Label”; the device type varies depending on the series

• The “Address Link Label” contains the MAC address (Media Access Control address) of the device and makes it possible to enter the IP address and the device name manually. The area of the “Address Link Label” on which the MAC address is printed can be separated from the remainder of the stick-on label if necessary using the perforation.

• The “Address Link Label” can be removed from the device and affixed in the installation and layout diagrams to designate the device.

• Once it is affixed in the documents, the “Address Link Label” establishes a unique reference between the mounting location, the MAC address or the device, and the associated control program. The time-consuming searching, reading, and manually writing down of the MAC addresses of all devices installed in the system are eliminated.

Leuze electronic BPS 348i 54

Each device with Ethernet interface is uniquely identified via the MAC address assigned during production. The MAC address is also listed on the name plate of the device.

If multiple devices are commissioned in a system, the MAC address of each installed device must be correctly assigned, e.g., during programming of the control.

 Remove the “Address Link Label” from the device.

 If necessary, add the IP address and the device name to the “Address Link Label”.

 Affix the “Address Link Label” in the documents, e.g., in the installation diagram, according to the posi-

tion of the device.

8.1.1 PROFINET - communication profile

The PROFINET communication profile defines how participants serially transmit their data via the transmission medium. Data exchange with the devices occurs primarily cyclically. For configuration, operation, observation and alarm handling, acyclic communication services are, however, used as well.

Depending on the communication requirements, PROFINET offers suitable protocols and transfer methods:

• Real Time communication (RT) via prioritized Ethernet frames:

Basic configuration

• Cyclical process data (I/O data stored in the I/O area of the control)

•Alarms

• Clock synchronization

• Neighborhood information

• Address assignment/address resolution via DCP

• TCP/UDP/IP communication via standard Ethernet TCP/UDP/IP frames:

• Establishing communication

• Acyclic data exchange, i.e., transfer of various types of information:

Parameters for the module configuration while communication is being established I&M data (Identification & Maintenance functions) Reading diagnostic information Reading I/O data Writing device data

8.1.2 Conformance Classes

PROFINET devices are categorized into conformance classes to simplify the evaluation and selection of the devices for the users.

The BPS corresponds to Conformance Class B (CC-B) and can use an existing Ethernet network infrastructure.

The BPS supports the following features:

• Cyclical RT communication

• Acyclic TCP/IP communication

• Alarms/diagnostics

• Automatic address assignment

• I&M 0 functionality

• Neighborhood detection basic functionality

• FAST Ethernet 100 Base-TX/FX

• Convenient device exchange without engineering tools

• SNMP support

8.2 Starting the device

To start the BPS:

 Connect the supply voltage.

The BPS starts up and, for devices with a display, the device status is displayed.

Leuze electronic BPS 348i 55

 Configure the BPS, e.g., for a Siemens SIMATIC-S7 control.

 Assign the BPS its individual device name and name the device.

Starting up the device

The default value of the input data bits after switching on the device corresponds to the specified initial value (generally ZERO).

For output data with status IOPS = Bad, the downstream functions are switched to a safe state. For example, an activated device or an output is deactivated. This is the case, for example, if the control is switched to the STOP mode.

In the event of a connection interruption, the device behaves in the same way.

The outputs are deactivated during device start-up.

8.3 Configuring for the Siemens SIMATIC-S7 control

The functionality of the BPS is defined via parameter sets which are organized in modules. The modules are part of the GSDML file (Generic Station Description Markup Language), which is supplied as an integral part of the device.

By using a user-specific project tool, such as, e.g., Simatic Manager for the Siemens programmable logic control, the required modules are integrated into a project during commissioning and its settings and parameters are adjusted accordingly. These modules are provided by the GSDML file.

Basic configuration

NOTICE

Observe SIMATIC Manager version!

 For the Siemens SIMATIC-S7 control, you need at least SIMATIC Manager version 5.4 + service

pack 5 (V5.4+SP5).

The following steps are necessary for commissioning:

• Preparation of the control system (S7 PLC)

• Installation of the GSDML file

• Hardware configuration of the S7 PLC

• Transmission of the PROFINET configuration to the IO Controller (S7 PLC)

• Device naming

• Check device name

Proceed as follows:

 To prepare the control (S7 PLC):

Assign an IP address to the IO controller (S7 PLC)

Prepare the control system for consistent data transmission.

 Install the GSDML file for the subsequent configuration of the BPS.

You can find the GSDML file at www.leuze.com > Products > Measuring Sensors > Sensors for Positioning > BPS 300i > (Name of the BPS) > Tab Downloads > Software/driver > GSDML file.

Alternatively, the GSDML file can be loaded from the BPS with the webConfig tool (see chapter 9):

HOME > INSTALLATION > GSDML file

The GSDML file stored in the BPS is always compatible with the firmware version of the BPS.

Leuze electronic BPS 348i 56

Basic configuration

General information on the GSDML file

The term GSD (Generic Station Description) stands for the textual description of a PROFINET device model. For the description of the complex PROFINET device model, the XML-based GSDML (Generic Station Description Markup Language) was introduced. In the following, the terms “GSD” or “GSD file” always refer to the GSDML-based format. The GSDML file can support an arbitrary number of languages in one file. Every GSDML file contains a version of the BPS device model. This is also reflected in the file name.

In the GSDML file, all data necessary for operating the BPS is described in modules: Input and output data, device parameters, definition of the control and status bits.

If parameters are changed in the project tool, for example, these changes are stored by the PLC in the project, not in the GSDML file. The GSDML file is a certified and integral part of the device and must not be changed manually. The file is not changed by the system either.

The functionality of the BPS is defined via GSD parameter sets. The parameters and their func- tions are structured in the GSDML 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 on the PROFINET 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. The default settings of the BPS can be found in the module descriptions.

GSDML file name structure

The file name of the GSDML file is constructed according to the following rule:

GSDML-[GSDML schema version]-Leuze-[item description]-[date].xml

[GSDML schema version] = Version identifier of the GSDML schema version used, e.g., V2.2

[Date] = Release date of the GSDML file in the format yyyymmdd.

This date also stands for the release date of the file.

Example: GSDML-V2.2-Leuze-BPS348i-20131003.xml

 Configure the hardware of the S7 PLC:

Add the BPS to your project. The PROFINET system is configured with the help of the hardware configuration (HW-Config) of the SIMATIC Manager.

Assign an IP address a unique device name.

Transfer the PROFINET configuration to the IO Controller (S7 PLC). Following successful transfer, the following activities take place automatically:

• Check of device names

• Assignment of the IP addresses that were configured in the HW Config to the IO devices

• Establishment of a connection between the IO Controller and configured IO devices

• Cyclical data exchange

Participants that have not been "named" cannot be contacted yet at this point in time!

Device naming PROFINET defines the "naming of the device" as the creation of a name-based relationship for a

PROFINET device.

 Set the device name.

Leuze electronic BPS 348i 57

Basic configuration

The PROFINET device has a unique MAC address that is part of the factory settings. The MAC address may be found on the name plate of the BPS. Multiple BPS devices can be distinguished by the MAC addresses displayed.

This information is used to assign a unique, plant-specific device name (“NameOfStation”) to the device via the "Discovery and Configuration Protocol (DCP)".

Every time the system is started up, PROFINET uses the DCP protocol for the IP address assignment, provided the IO-device is located in the same subnet.

 Assign the device names to the configured IO devices.

Select the BPS using its MAC address. The unique device name (which must match the name in the HW Config) is then assigned to the BPS.

 Assign the IP address to the MAC address (individual device name).

At this point, assign another IP address (suggested by the PLC), a subnet mask and, if required, a router address, and assign this data to the named participant (device name).

From now on, and when programming, only the unique device name (max. 255 characters) is used.

 Check device name

After completing the configuration phase, check the device names that have been assigned.

NOTICE

Assign unique device name!

 Ensure that the device names are unique and that all participants are located in the same subnet.

8.4 PROFINET project modules

From the perspective of the device, a distinction is made between interface-specific parameters and internal parameters:

• Interface-specific parameters Parameters that can be changed via the interface (see modules described in the following).

• Internal parameters Parameters that are changed only via a service interface. They retain their value even after the interface-specific configuration.

NOTICE

Overwriting of data by PLC!

 Note that the PLC overwrites the data set via the service interface.

 During the interface-specific configuration phase, all interface-specific parameters changed via the

service interface are overwritten. This also applies for the parameters from modules that were not configured.

 During the configuration phase, the BPS receives parameter telegrams from the Controller (master).

Before the parameter telegrams are evaluated and the respective parameter values are set, all interface-specific parameters are reset to default values. This ensures that the parameters of modules that are not selected are set to the default values.

NOTICE

Do not activate any universal modules!

 If the control makes a so-called “universal module” available, the universal module may not be acti-

vated for the BPS.

You can find the default values of the BPS in the module descriptions.

8.4.2 DAP module – permanently defined parameters

On the PROFINET, parameters may be stored in modules or may be defined permanently in a PROFINET participant. Depending on the configuration tool, the permanently defined but adjustable parameters are called “common” parameters or device-specific parameters.

The common parameters must always be present. They are defined outside configuration modules and are thus connected to the base module (DAP: Device Access Point) that is addressed via Slot 0/Subslot 0.

The following list contains the device parameters that are permanently defined in the BPS (DAP Slot 0/ Subslot 0) but are configurable. These parameters always exist and are available independent of the modules.

Behavior of the BPS during measurement stop/start

If the scanning beam is incident on the BCB at the moment the laser diode is switched on, the BPS returns valid measurement values after approx. 10 ms.

If the BPS is reactivated from standby, the motor must first reach its nominal rotational speed. It takes a few seconds before the BPS returns any valid measurement values.

Module ID: 1009 with submodule ID: 1

The module makes parameters available to handle any errors should they occur.

If there is a brief disturbance in the position value or the speed calculation in the device, the BPS sends the last valid measurement value for a configured time.

If the BPS can again calculate valid measurement values within the error delay time, these are output. The disturbance is made evident only as a small increase in the output measurement value.

If the problem with the calculation lasts for a longer period of time, it is possible to configure how the BPS is to behave.

8.4.12 Module 10 – Speed

Module ID: 1010 with submodule ID: 1

The module is used to output the current speed in the desired resolution.

The unit (metric or inch) is set via module 1 (position value) and also applies to the speed. If module 1 is not configured, the value is output with the default unit of measurement (metric). The sign of the speed is dependent on the count direction selected in module 1. With the default counting direction (positive), a positive speed is output for movement towards larger tape values. Movement towards smaller tape values results in negative speeds. Measurement value prepa- ration averages all speed values calculated during the selected period (averaging) to yield a speed output value.

The module contains parameters (with parameter data length of 2 bytes) and input data (with consistent input data length of 4 bytes), but no output data.

always performed from range start to range end.

Example: if the range start is only performed in the direction from

and the range end is

5500

5000

, the direction-dependent check is

If the check is independent of direction, the order of range start and range end is irrelevant. Depending on the selected switching mode, if the value is above or below the defined limits, the limit value status in module 16 (see chapter 8.4.18) is set and, if configured, the switching output is appropriately set via module 4 (see chapter 8.4.6) or module 5 ( see chapter 8.4.7).

If the range start is identical to the range end, a continuous, direction-independent limit value check is performed.

The module contains parameters (with parameter data length of 13 bytes), but no input data and no output data.

Start-up configuration of the switching inputs and outputs!

 The configuration for switching inputs and outputs SWIO 1 and SWIO 2 is generally performed via the

GSDML file.

The settings configured with the webConfig tool that differ from the GSDML configuration are overwritten on start-up by the PROFINET master with the settings made via the GSDML file. Settings that cannot be configured via PROFINET, e.g., timing functions, are not overwritten.

 The PROFINET modules 4 and 5 configure switching inputs and outputs (I/Os) SWIO 1 and SWIO 2

Timing functions of the switching inputs/outputs The timing functions (e.g., start-up delay) can only be configured with the webConfig tool. The configuration of the timing functions is not overwritten by the PROFINET master on start-up.

• 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

, 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).

10 Diagnostics and troubleshooting

10.1 What to do in case of failure?

After switching on the BPS, display elements (see chapter 3.3) assist in checking the proper function and troubleshooting.

In case of error, you can determine the error from the LED displays. With the error message you can determine the cause of the error and initiate measures to rectify it.

 Switch off the system and leave it switched off.

 Analyze the cause of the error using the operation indicators, the error messages and the diagnostic

tools (also with the help of the webConfig tool,

NOTICE

Contact Leuze electronic subsidiary/customer service.

 If you are unable to rectify a fault, contact the Leuze electronic branch responsible for you or call the

Leuze electronic customer service (see chapter 12 "Service and support").

10.1.1 PROFINET-specific diagnostics

The following diagnostics options are available with PROFINET:

• Event-related diagnostics

• State-related diagnostics

The BPS uses the event-related diagnostics for high-prioritized events/errors and the state-related diagnostics for preventative maintenance and the signaling of low-prioritized events or warnings.

DIAGNOSTICS

Diagnostics and troubleshooting

tab) and rectify the error.

Event-related diagnostics PROFINET transmits events within an automation process as alarms that must be acknowledged by the

application process.

The following events are possible:

• Process alarms: Events that originate from the process and are reported to the control.

• Diagnostic alarms: Events that indicate the malfunctioning of an IO device.

• Maintenance alarms: Transmission of information to avoid the failure of a device through preventative maintenance work.

• Manufacturer-specific diagnostics

To identify the alarms uniquely, they are always reported via a slot/subslot. The user can prioritize diagnostic and process alarms differently. In addition, all alarms are entered into the diagnostics buffer. The diagnostics buffer can be read by a supe-

rior instance via acyclic read services.

State-related diagnostics To report malfunctioning or status changes in a field device to a system control, it is possible to enter low-

priority diagnostics messages or status messages only in the diagnostic buffer instead of actively reporting them to the superior control. This option can also be used for preventative maintenance or for low-priority warnings, for example.

Diagnostics Description BPS

10.1.2 Diagnostics with webConfig tool

System events are displayed in the webConfig tool via the are recorded in the event log. Depending on their importance, the events are classified as info, warning, error and critical error. The statistics counters detect the number of all recorded as well as non-acknowledged messages. With the message filters, the events can be filtered according to their status and their class.
