ProfiHub A5 and B5 are advanced, flexible
and robust network components for
PROFIBUS DP installations, to implement
long multi-device spur lines and backbone
structures with star/tree segments.
PROFIBUS DP is a high speed communication
bus that has to 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.
Innovative components for such applications are
the ProfiHub A5 and B5. These are perfect
economic solutions to implement 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 A5 and B5 refresh a
received message on one Channel and
transfer it to all the other Channels (chicken
foot topology).
Because the ProfiHub A5 and B5 create isolated
segments, the devices can now be removed and
added during operation. Also 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 32 DC Voltage (110/230V AC versions
are also available). For troubleshooting, maintenance and commissioning the ProfiHubs are equipped
with a display on the outside, which indicate the status of each Channel (Data and Error).
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.

Cost Savings.
Every 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 ProfiHubs can be grounded by 3 methods:
1) Direct grounding
2) Indirect grounding (through a capacitor)
3) Combination of direct and indirect.
In most cases it is recommended always to use Direct Grounding with the power supply and the
shielding of the PROFIBUS cables. If you do not want to ground all or some cables to the common
ground, the cable shielding should be connected to pin ‘I’. A capacitor with a parallel high value
resistor will separate the 2 potentials (Fig. 5).
If by accident on 1 channel the Direct Grounding is connected with the Indirect Grounding, the Direct
Grounding “wins”.

The ProfiHub A5 can be installed everywhere in a non-hazardous area that complies with IP 65 (DIN
40 050) and the specified temperature range of -40 to +75o Celsius.
4.2 Position
The ProfiHub A5 can be installed in every position, but it is recommended to install it with the cable
glands pointing down to create a more reliable protection against moist and dust (water compartment
and glands). In this position it is also easier to read the status display.
4.3 Mounting
The ProfiHub A5 has 4 mounting holes for 4..5 mm screws (Fig. 9). To reach the holes on position 1
and 2, the top lid has to be removed.

2) Be careful with the flat cable that connects the lid with the PCB.
Connect the DP backbone cable to the bottom connector of the Main-Channel (Fig. 11). If the ProfiHub
is not the last device on the bus segment, connect the Bus-Out cable to the top connector of the MainChannel (Fig. 11).

Don’t forget to switch the termination ON at the other end of the segment and make sure it is
The ProfiHub recognizes the transmission speed by default. If it is required that the ProfiHub is locked
to a certain transmission speed, switch S100 should be set to the required value (Fig. 14). The switch
can be reached by removing the top lid.
To set the transmission speed, you need a 3 mm screwdriver.

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 -20 to +60o Celsius.
5.2 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 display.
5.3 Mounting
The ProfiHub B5 has to be mounted on 35 mm DIN-rail with a minimum width of 167 mm.
5.4 Power Supply
The 3-pin screw type power connector is located on the bottom left of the ProfiHub B5 (Fig. 15).
1 = + (left)
2 = - (middle)
3 = Indirect grounding (right)
The power supply has to comply with the following specifications:
Procedure
To connect the 24V supply to the 3-pin screw-type terminal, proceed as follows:
- Strip the insulation from the cable or the conductors for the 24V power supply.
- Secure the conductors in the screw-type terminal.
Note: There is a grounding point that can be used.
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:
- All the LEDs should be shortly blinking.
- The POWER LED is ON.
- The READY LED is ON or Blinking.
It is recommended to use a power supply with a ground lead (3-wire).
5.5 Backbone
Connect the DP backbone cable to the bottom-left connector of the Main-Channel (Fig. 16). 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. 16). The second method is to place a PROFIBUS standardized plug with an
in/out cable on the DB9 connector.

The ground rail has to be mounted inside the casing to
supply a common grounding area for all cable
shielding. It improves the EMC behaviour and it
supplies a good construction for vibrations. Not useable
for capacitive grounding!
Unique number of a device connected to the network. With PROFIBUS this
can be 0 to 126. 127 is a broadcast address.
Analyzer
Software tool to observe the protocol traffic. Combi-Analyzers can also
inspect the signal quality.
Other term: Bus Monitor.
Example: ProfiTrace.
Backbone
The primary bus cable. Most of the time only the control systems, ProfiHubs
and fiber optic couplers are connected to this cable. The field devices are
connected behind the ProfiHubs and fiber optic couplers.
Bit Time (TBit)
The bit time TBit is the time, which elapses during the transmission of one
bit. It depends on the baudrate and is calculated as follows TBit = 1 (bit) /
baudrate (bps).
Examples:
12 Mbps --> TBit = 83 ns
1,5 Mbps --> TBit = 667 ns
Busparameters
Settings that define the timing behaviour on the bus. They are defined in the
master. Examples: Tslot, MaxTSDR.
C
Capacitance.
DGND
Digital Ground.
DIN
German Institute for Standardization (www.din.de).
DP-V0
DP-V0 is the basic stage of the PROFIBUS DP communication protocol. DPV0 devices (master and slaves) perform the following basic functionalities:
- Cyclic exchange of I/O data between controlling and slave devices
- Device, Identifier (module) and Channel related Diagnosis
- Parameterization of DP-slaves
- Configuration of DP-slaves
DP-V1
DP-V1 is the first stage of extension of PROFIBUS DP after DP-V0. DP-V1
devices shall comply with the following features:
- Device related diagnosis is replaced by status and alarms.
- The first three octets of the user parameterization data are now
standardized
DP-V2 is the second stage of extension of PROFIBUS DP after DP-V1. DPV2 devices shall comply with the following features:
