Bar code positioning systems
Advantages for you
- Simple fieldbus integration: The already-integrated fieldbus interfaces enable adaptation to various control systems. If configurations are necessary, they are performed directly via the control systems (e.g., GSDML file) or via the web server integrated in the device (e.g., with SSI interface). The devices are configured directly via the control. You thereby save time during installation and costs for otherwise necessary connection units. Moreover, no configuration is required should device replacement be necessary.
- Large performance reserve: Thanks to a working range of ± 60 mm, the systems, with their laser technology, are very tolerant of mechanical fluctuations. They thereby offer reliable position detection with the largest performance reserve in every environment
- Predictive maintenance: The reading quality monitoring constantly analyzes the decodability of the bar codes and indicates a decline in function reserve in good time. The availability of the system is thereby ensured.
- Simple mounting: The sophisticated fastening concept enables simple and robust mounting of the devices. Should replacement be necessary, the devices can be exchanged position-neutral, i.e., without realigning.
- Modularly selectable function range:
- Various connection hoods (terminals, M12, cables) for optimum integration in your control
- Optional display for visualization and diagnosis
- Optional optics heating for low-temperature applications.
Highlights

integrated connectivity
The BPS 300i transfers position data as well as status information via various interfaces that are integrated in the device. Additional gateways no longer required. Communication is especially comfortable if data exchange with the control can take place via defined GSD/GSDML or ESI file structures.

Integrated webConfig tool
An integrated web user interface enables access to comprehensive diagnosis that can also be designed as remote access if necessary. Devices with, e.g., SSI or RS 485/RS422 interfaces can be configured very easily with the easy-to-understand, graphical user interface.

Bar code tapes (BCB)
The second fundamental element of a bar code positioning system is the bar code tape. A self-adhesive and highly flexible plastic tape is printed with a unique bar code at regular intervals. This technology makes the tape resistant, resilient and mechanically durable. The position value is also printed in "plain text" to simplify handling. This tape, which may be up to 10,000 m in length, can be simply affixed along the travel path and also enables use on horizontal and vertical curves, such as those found on electrical monorail systems.
The bar code tape can be delivered according to individual requirements. Here, the tape height, the tape length as well as the start and end position can be adapted to the given application. Should the tape happen to be damaged, the necessary section of tape is available online on the Leuze website and, in a first step, can even be self-printed. This is also possible without any time delay, thereby ensuring system availability. In a subsequent step, the tape section can be ordered as an originally manufactured bar code tape.

Highlights

Simple and safe
The sensor can be parameterized and integrated effortlessly and reliably – without any additional tools, directly in your familiar work environment. Setup is intuitive and convenient, whether in the F-PLC’s hardware manager or directly via the safety card in the drive's frequency inverter. Thanks to the GSDML or parameter file, the device settings are immediately available in the hardware manager or in the safety card’s device library. This allows for seamless integration and configuration with minimal risk of error, significantly simplifying use and considerably reducing effort. Depending on the requirements, the safe position value can be further processed via the SSI or PROFIsafe interface – flexibly and reliably, entirely in accordance with your concept. Safe speed output is also available as a function with the PROFIsafe model.

Suitable for curved routes (tracks) and precise positions
The particularly robust and resistant BCB bar code tape, which is affixed along the transportation path, means even curved track layouts up to 10,000 meters long can be clearly and reliably detected.
Additional functions, such as speed output, complement automatic transport systems perfectly. They help to reduce wear, shorten braking distances and make efficient use of buffer zones – for a smooth and safe process.

Safe position detection via frequency inverter
The FBPS 600i requires just one sensor for safe position detection. The device is connected to a safe evaluation unit – e.g. a frequency inverter – via two SSI interfaces. In addition, the devices already meet the requirements for PL e/SIL 3. This makes safety functions particularly easy to implement and reduces installation and service costs.

Safety control with direct position sensor connection
The FBPS 648i device is connected to a safe control via a PROFIsafe interface. A linear topology can be set up with the integrated switch. A non-safe SSI interface is also available. In addition to the safe position value, this device also provides a safe speed output.

Suitable for fast movements
The FBPS 600i is ideal for position detection in applications involving fast movements, e.g. on stacker cranes. For this purpose, the FBPS 600i has an extremely short error reaction time of just 10 ms. This allows speed curves and handling performance to be optimized.

Reliable operation
The FBPS 600i operates with exceptional reliability. Each scanning process reads multiple codes, from which the software determines highly accurate position values. The oblique path of the scanning beam and the movement of the device ensure that each code is scanned at different points. This prevents reading errors caused by local contamination or damage.
The bar code tape is also optimized for industrial use. The self-adhesive plastic tape is UV resistant, extremely resilient and mechanically durable. In addition, the printed position values are easy to read and simplify handling.

Always quick and easy to install
The clever fastening concept with quick-change system ensures simple mounting of the FBPS 600i. The devices are securely mounted to the clamp bracket using an easily accessible screw. This saves time during installation and allows the devices to be quickly replaced in the event of servicing. Furthermore, the FBPS 600i is easy to integrate into any system thanks to its large working range of 50 to 170 mm.
Suitable for a wide range of environmental conditions
The wide temperature range enables use in various systems with positioning tasks, even under demanding conditions. A model with integrated optics heating is also available for environments with high humidity and low temperatures. This ensures increased availability and prevents fogging so that the sensor always works reliably.
Application

Safe positioning with bar code positioning system
Requirement:
The stacker crane or load receptacle must be positioned in the X-direction (travel axis) and Y-direction (lifting axis) accordingly for the position to be approached. Often the risk assessment requires safe position and speed monitoring. For this purpose, safe position detection is necessary.
Solution:
The FBPS 600i safe bar code positioning system requires just one sensor for safe position detection. The device is connected via two SSI interfaces or a PROFIsafe interface to a safe evaluation unit – e.g. a frequency inverter – or safe PLC and is suitable for applications up to PL e. This makes it easy to implement safety functions.

Positioning of the transport unit
Requirement:
For control of the electric monorail system, the position of the transport unit on the carrier must be known with millimeter precision at all times. “Safe positioning” must be ensured especially when workers are working very close to the transport unit.
Solution:
The safe FBPS 600i bar code positioning systems enable precise positioning over a length of up to 10,000 m. The devices can be easily integrated into the control thanks to a wide range of interfaces. The self-adhesive bar code tapes are optimized for industrial application and are extremely resilient.

Synchronous trolley positioning
Requirement:
The crane or trolley should be positioned according to the point to be approached. Several cranes can be located on one guide rail.
Solution:
The BPS 300i bar code positioning systems or the safe version FBPS 600i enable exact positioning. The devices can be easily integrated into the control thanks to a wide range of interfaces. The self-adhesive bar code tapes are optimized for industrial application and are extremely resilient.

Skillets in assembly
