1. Product Description ProfiHub B5+R is an advanced, flexible and robust network component for PROFIBUS DP installations, to create 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. The innovative ProfiHub B5+R is the perfect component for such applications. It is an economic solution to realise reliable spur...

• 5 Galvanic isolated outgoing channels (repeater segments) • Advanced Diagnostic capabilities • Transparent for all PROFIBUS DP protocols • DP - RS 485 specifications for each channel • Cable redundancy for channel 4+5 • 9.6 Kbps to 12 Mbps. • 31 devices per channel • 1200 m spur line length (depending on transmission speed) • Redundant power supply • No limit in serial placement or cascading of ProfiHubs (only limited by busparameters) • Alarm contact, with manual reset button • No address required (except for the B5+R Diagnostics option) • Integrated termination facilities (switches) • Configurable...

Each spur line can be 200m at 1,5 Mbps Wiring problems do not spread to the other spur lines Fig. 3 - Long spur lines to instruments and the possibility to remove/insert them during operation. Short circuit protection on each spur line is automatically provided. 1.2 Application areas • Dynamic spur lines to actuators, flow meters and pH analyzers • Removable drives and motors • Pull/Plug motor control centers (drawers) • Roof mounted devices in tank farms • Barrier for non galvanic isolated equipment • Networks with requirement for High Availability/uptime • Large star/tree structured networks...

Fig. 4 - Because of the isolation and intelligence the ProfiHub provides, it can be used as a barrier for electrically sensitive segments. This keeps the backbone and other Channels clean. 1.4 Channel Structure Each Channel is electrically isolated and internally connected to the transparent intelligent backbone. The termination is switchable and powered by the ProfiHub. The shielding of the PROFIBUS cable can be directly grounded or indirectly grounded (see the next paragraph). RX-OK Powered Termination Intelligent Backbone Isolation Circuit Term. Switch Indirect grounding Isolated Area To direct...

The ProfiHub B5+R can be grounded by 3 methods: 1. Direct grounding on the Ground Rail 2. Indirect grounding (through a capacitor) 3. Combination of direct and indirect. The power supply must be grounded directly on the Ground Rail. The shielding of the PROFIBUS cables can be directly or indirectly grounded. If you do not want to ground all or some cables to the common ground, i.e. compensating current, the cable shielding must be connected to pin 'I' which stands for Indirect grounding. A capacitor with a parallel high value resistor will separate the 2 potentials (Fig. 5), ensuring protection...

1.7 Cable types for PROFIBUS DP The cable type must comply with the PROFIBUS DP cable specifications for RS 485 (Fig. 7). Loop resistance Wire diameter Wire area Fig. 7 - PROFIBUS DP cable specifications The ProfiHub B5+R can handle cables based on multiple protection sheaths with an overall cable diameter between 6 to 12 mm (Fig. 8). Flexible cable Robust cable Hybrid cable Trailing cable Food cable Festoon cable Shipboard cable FRNC cable Fig. 8 - Cables with different protection sheaths.

The Status LEDs on the ProfiHub are very useful for diagnostics. 1.8.1 The red error LED 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 for channel 4 or 5 is a problem in the redundant cabling (if the ProfiHub is set to redundant)....
