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...

4 Galvanic isolated outgoing channels (repeater segments). Advanced Diagnostic capabilities 2 Fiber Optic channels. Transparent for all PROFIBUS DP protocols. DP - RS 485 specifications for each channel. Cable redundancy for copper channel 3 and 4 9.6 Kbps to 12 Mbps. 31 devices per channel. 3000 m cable length for FO channel 1 and 2 1200 m spur line length for copper channel 1 to 4 (depending on transmission speed). Redundant power supply No limit in serial placement or cascading of ProfiHubs. Alarm contact, with manual reset button. No address required (except for the B4FO2+R Diagnostics...

DP Fiber Optic Backbone 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 Create Fiber Optic backbones 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...

1.5 Channel Structure Each copper 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.

The ProfiHub B4FO2+R can handle cables based on multiple protection sheaths with an overall cable diameter between 6 to 12 mm (Fig. 8). Robust cable Hybrid cable Trailing cable Food cable Festoon cable Flexible cable Shipboard cable FRNC cable Fig. 8 - Cables with different protection sheaths 1.9 Cable lengths for fiber optic The maximum cable length for fiber optic cables is 3 kilometers if G62.5 / 125 or G50/125 cable is used. If PCF/HCS cable is used, the maximum is 200 meters. 1.10 Cable types for fiber optic The following cable types can be used with the ProfiHub B4FO2+R: G62.5/ 125...

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...

2. Installation Instructions ProfiHub B4FO2+R 2.1 Location The ProfiHub B4FO2+R can be installed everywhere in a non-hazardous area that complies with IP 20 (DIN 40 050) and the specified temperature range of -25 to +70o Celsius or -13 to +158˚ Fahrenheit. 2.2 Position The ProfiHub B4FO2+R can be installed in every position, but it is recommended to install it with the cables pointing down. In this position it is also easier to read the status LEDs. 2.3 Mounting The ProfiHub B4FO2+R can be mounted on 35 mm DIN-rail with a minimum width of 167 mm. Mounting brackets are available for mounting...
