The ProfiHub B4FO2+R is a robust network component for PROFIBUS DP installations, enabling fiber optic backbone structures and long multi-device star/tree segments. It supports high-speed communication and redundancy, transforming into a reliable redundant repeater solution. It includes four galvanic isolated repeaters and an Optical Link Module (OLM), handling up to 31 devices per channel.
- Four galvanic isolated outgoing channels
- Advanced diagnostic capabilities
- Two fiber optic channels
- Transparent for all PROFIBUS DP protocols
- Supports cable redundancy and various transmission speeds
- Integrated termination facilities and configurable grounding system
- IP 20 classification and increased temperature range
The ProfiHub B4FO2+R is ideal for creating fiber optic backbones, dynamic spur lines, removable drives, and networks requiring high availability. It is also used in large star/tree structured networks and as a barrier for non-galvanic isolated equipment.
The device allows hot slave insertion and removal during operation, provides short circuit protection on each channel, and supports easy network extension. It is compact, robust, and offers cost savings.
Instructions cover location, positioning, mounting, power supply, grounding, and alarm contact setup. It also includes fiber optic backbone configuration, delay time calculation, spur segments, termination, baudrate switch settings, and channel redundancy.
Setup and configuration instructions for the diagnostics device are provided, covering enabling the device, changing the default PROFIBUS address, and configuring status indicators and alarms.
Technical specifications detail the operational parameters and capabilities of the ProfiHub B4FO2+R.
Contact information for PROCENTEC's sales offices and distributors is included, along with order codes and certification details.
A glossary of terms and additional information about PROCENTEC are provided to aid understanding and context.
The ProfiHub B4FO2+R features electrically isolated copper channels connected to an intelligent backbone. Termination is switchable and powered by the ProfiHub. Grounding can be direct, indirect, or a combination, with specific instructions for grounding the power supply and PROFIBUS cable shielding.
PROFIBUS DP cables must meet RS 485 specifications, with specific parameters for impedance, capacity, and wire dimensions. Fiber optic cables have a maximum length of 3 km for G62.5/125 or G50/125 types, and 200 meters for PCF/HCS cables.
Status LEDs provide diagnostic information, indicating power status, transmission speed detection, and communication errors. The red Error LED signals corrupt messages or issues with redundant cabling.
The device can be installed in non-hazardous areas within specified temperature ranges. It can be mounted on a DIN-rail or directly on a wall, with recommendations for grounding and power supply connections.
The ProfiHub supports redundant power supplies, with specifications for voltage and current. An alarm contact monitors power supply status and can trigger external alerts.
Fiber optic channels can create a backbone to other ProfiHubs or ComBricks. Spur segments connect to specific channels, with guidelines for termination and testing.
Calculations for delay time in fiber optic applications are provided, with formulas to adjust bus parameters based on cable length and number of modules.
The ProfiHub can auto-detect transmission speed or be manually set using a rotary switch. Different settings are available for normal and robust repeating modes.
The rotary switch settings on the ProfiHub B4FO2+R are immediately active without needing a device restart. The auto baudrate detection feature identifies the correct baud rate within 10 seconds of receiving the first telegram. If no correct message is received within 50 seconds, the baud rate lock is lost.
The device offers two repeating modes: Normal and Robust Repeating. In Normal mode, bits are transferred immediately with minimal delay. In Robust Repeating mode, only valid PROFIBUS messages are repeated, enhancing network stability in EMC-sensitive environments. This mode requires an increase in the MinTSDR parameter in the PLC bus parameters.
Redundancy is enabled by setting the rotary switch to 2 or 5, allowing the last two copper channels to form a redundant path. If one cable fails, the other ensures message delivery, triggering an alarm and blinking the red 'ERROR' LED. The MinTSDR parameter should be adjusted similarly to Robust Repeating mode.
The built-in Diagnostics Device logs network statistics and diagnostics, providing feedback on network health and failures. It can alert the PLC or DCS of issues like repeats, illegals, and power supply problems. The device can be configured using a rotary switch and supports various diagnostic messages and statistics monitoring.
The Diagnostics Device can be configured modularly, with options for alarm confirmation, redundant status, baudrate status, relay status, power status, termination status, channel status, livelist status, and statistics. Each module has specific input and output bytes for configuration and status indication.
User-definable parameters allow customization of the device's behavior and options. The device sends diagnostic messages on PROFIBUS when certain conditions change, such as livelist changes, bitrate errors, and power status changes.
The document outlines various diagnostic features of the ProfiHub B4FO2+R, including redundancy status changes, termination status changes, channel status changes, and statistics changes. Users can toggle diagnostics for each item in the configuration tool. The 8th byte of a diagnostic message indicates enabled or disabled options.
Users can select which statistics trigger diagnostic messages. Not all statistics are relevant for every network, and some, like Syncs, are disabled by default. Key statistics include Lost, Sync, Repeats, Illegals, and Diagnostics changes.
For critical applications, the 'Extended Diagnostics' option can be enabled for events and statistics, sending a message with the 'Extended Diagnostic' bit on. This is visible in tools like ProfiTrace.
The Alarm Relay can be activated on events and statistics changes, with immediate switching except for the Lost event, which may delay.
Users can adjust the duration of Extended Diagnostics warnings and the Device Lost timeout. The data format can be switched between Motorola and Intel formats.
A plugin for the Diagnostic Device is available for download, aiding in message interpretation and troubleshooting.
The document provides detailed technical data, including dimensions, weight, operating conditions, protocol support, transmission speeds, and cable specifications for both fiber optic and copper cables.
The device complies with various standards, including CE, FCC, and UL, ensuring safety and performance.
The document lists contact details for PROCENTEC headquarters and distributors worldwide.
The document lists the order code for the ProfiHub B4FO2+R, which is 17420R. This model includes diagnostics, redundant channels, alarm contact, and redundant power input. Since January 2019, all types have been merged into this single type, making them drop-in replaceable.

1. Product description 1.1 Introduction ProfiHub B4FO2+R is an advanced, flexible and robust network component for PROFIBUS DP installations, to create fiber optic backbone structures and long multi-device star/tree segments. PROFIBUS DP is a high speed communication bus that must comply with strict rules concerning spur lines, because of possible reflections that could lead to communication disturbances. If spur lines or star segments are required, costly investments in repeaters have to be done. When redundancy is enabled, the ProfiHub B4FO2+R is transformed to a low cost extremely reliable...

The Status LEDs on the ProfiHub are very useful for diagnostics. The red error LEDs will blink shortly if a corrupt message enters the ProfiHub. More specifically, this can be a Parity error (the parity checksum of the byte is incorrect) or a Framing error (the FCS byte is different than the real message). It is necessary to investigate further with an oscilloscope to find out what the problem is. This can easily be done with ProfiTrace. Another reason for the red error LED is a problem in the redundant cabling (if the ProfiHub is set to redundant). If the redundant line is fixed, press the 'Alarm...
