1 Product Description
ProfiHub B5+ 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+ 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 5 galvanic
isolated transparent repeaters. 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
B5+ refreshes a received message on one Channel and transfers it to all the other Channels
(chicken foot topology).
Because the ProfiHub B5+ 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 10 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).
If bus redundancy is enabled, 2 segments will form a
redundant pair which is completely compatible with the ABB
RLM01. An alarm contact is linked to events based on the
status of the power supply and the bus redundancy status.

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).
1.5 Grounding System
The ProfiHub B5+ 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 of the signal against non-DC disturbances.
If by accident on 1 channel the Direct Grounding is connected with the Indirect Grounding, the
connection to the Direct Grounding bypasses the capacitor in the Indirect Ground connection. The
current on the shield will flow to Direct Ground.

2 Installation Instructions ProfiHub B5+
2.1 Location
The ProfiHub B5+ 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.
2.2 Position
The ProfiHub B5+ 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 B5+ can be mounted on 35 mm DIN-rail with a minimum width of 167 mm. Mounting
brackets are available for mounting the B5+ directly on a wall. The ProfiHub B5+ has only been UL
and DNV approved with 35 mm DIN-rail mounting!
The supplied rubber studs need to be placed on the back of the housing of the ProfiHub B5+ for extra
fixation. This is to prevent the product to potentially slide off the DIN-rail. See
Fig. 9
for an example.
When used in DNV environments these rubber studs need to be installed!

2.4 Power Supply
To comply with UL certification regulations the power supply must be a Limited Power Source (LPS) or
NEC Class 2 or CEC Class 2 that cannot exceed 100VA.
The two 2-pin screw type power connectors are located on the left of the ProfiHub B5+ (
Fig. 10
).
1 = +(left)
2 = -(right)
Both power connectors are linked 1-on-1 to the internal power supply of the B5+. If one power supply
fails, the other takes over without delay time. When redundancy is not required, it is sufficient to use
one power connector. Please note that when using only one power supply, a voltage of max. 0.25 V
will exist on the other unconnected power connector, as shown in
Fig. 11
.
If only one power supply is used, the alarm contact is closed. If two power sources are connected, the
contact is open. As soon as one of the power supplies fails, the contact will close and the Power
Indicator LED will blink.
For UL certified installations the power supply must comply with the following specifications:
- Limited Power Source (LPS) or NEC Class 2 or CEC Class 2
- Voltage: 12 - 24 VDC
- Current: min 275 mA
- Wire diameter: < 2.5 mm2

Procedure
To connect the 24V supply to the 2-pin screw-type terminal, proceed as follows:
- Strip the insulation from the cable or the conductors for the 24V power supply.
- Add cable crimp terminals/wire ferrules to the conductors.
- Secure the crimp terminals in the screw-type terminal.
To connect the power supply, you need a 3 mm screwdriver.
Testing
If the power is switched on it can be diagnosed by the following indicators:
- LEDs should be blinking in a circular animation for a short time.
- The POWER LED of the respective power connector (1, 2 or both) is ON.
- The READY LED is ON or Blinking, depending on baud rate lock.
2.5 Grounding of the power
It is recommended to use a power supply with a ground lead (3-wire). Connect the ground
lead of the power lead to the Ground Rail of the ProfiHub B5+. Connect the Ground Rail to the
common ground with a separate ground lead. See Fig. 12 for an example.
Fig. 12 - Connection to Ground Rail

2.6 Relay contact
The ProfiHub B5+ features a potential-free relay contact. This alarm contact can be used to monitor
the power supplies. Example applications are: Connect a LED tower, alarm buzzer, SMS server or use
it as a digital signal for the PLC. On the B5+RD version the relay can also be used for alarming in case
of retires, illegals, or other events. For more information refer to Chapter 3.
If only one power supply is used, the alarm contact is closed after 60 seconds after start-up. If two
power sources are connected, the contact is open. When one of the power supplies fails for 3 seconds
or more, the contact will close and the Power Indicator LED will blink. If you are using only one power
source and wish to use the Relay contact, simply connect Power 1 to Power 2.
In the case of an interrupted power supply you can reset the contact by pressing the ‘Reset’ button.
The contact will open and the LEDs will stop blinking.
The Alarm contact is also switched when the ProfiHub is in Redundant mode and one of the redundant
paths fails.
The maximum power to be connected to the alarm contact is 24 VDC. The maximum current
consumption is 500 mA.
It is advised to use a Limited Power Source (LPS) of NEC Class 2 or CEC Class 2 for powering the
alarm contact.
2.7 Backbone
Connect the DP backbone cable to the bottom-left connector of the Main-Channel (
Fig. 13
). If the
ProfiHub is not the last device on the bus segment, connect the Bus-Out cable to the right connector
of the Main-Channel (
Fig. 13
). The second method is to place a PROFIBUS standardized plug with an
in/out cable on the DB9 connector.

The termination of the Main-Channel has been set to OFF by default. If the ProfiHub is the last device
on the segment, the termination must be set to ON (
Fig. 15
).
The termination of the Channels have been set to ON by default, because it is assumed that the new
segment is started at the ProfiHub (
Fig. 15
).
The termination LED of the corresponding Channel is activated when the termination switch is set to
ON.
When the DB9 connector is used and the cable starts at the ProfiHub, it is recommended to
use the termination on the DB9 plug and NOT the ProfiHub. This way, the connector can be removed
while maintaining termination on the bus.
