1. Product description
1.1 Introduction
ProfiHub B2FO2+ 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.
The innovative ProfiHub B2FO2+ is the perfect component for such applications. It is an economic solution to
realise reliable spur lines in high speed DP networks. They have the functionality of 2 galvanic isolated
transparent repeaters and an optical link module in one device. This allows network structures with extended
spur lines that individually can handle a maximum of 31 devices and a length equal to the main bus. The
ProfiHub B2FO2+ refreshes a received message on one Channel and transfers it to all the other Channels
(chicken foot topology).
Because the ProfiHub B2FO2+ creates isolated segments, the devices can now be removed and added during
operation. Also most electrical bus problems and EMC disturbances in a spur do not spread to the other
segments. The intelligent logic and isolation circuits of the ProfiHubs do not change the bit width. This means
the ProfiHubs do not have limitations in serial placement. The logic also detects the transmission speed
automatically.
To assist the installation work, termination is integrated and can be switched on/off. The grounding concept is
also selectable: direct or capacitive grounding. The ProfiHubs are powered by a 12 to 24 DC Voltage. For
troubleshooting, maintenance and commissioning the ProfiHubs are equipped with LEDs on the outside, which
indicate the status of each Channel (Data and Error).
