Important Notices .................................................................................................................................. 4
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.

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.
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).
Fig. 5 - Channel structure
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 (
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.
Fig. 5
), ensuring protection of the signal against non-DC disturbances.
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 +70
o
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
When used in DNV environments these rubber studs need to be installed!
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+ (
1 = + (left)
2 = - (right)
Fig. 10
).
Fig. 10 - Power connectors and LEDs
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.
Fig. 11 – Maximum voltage on unconnected Power Connecto
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
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 (
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.

Pin “B”: Red wire
Pin “I”: Indirect cable shielding
Note: Connecting the Indirect cable shielding is not required when the ground clips are used.
Testing
- If the Main-Channel recognizes valid PROFIBUS messages from one or more connected devices,
the RX-OK LED of the Main Channel should be blinking.
2.8 Spur Segments
Connect the spur segments to the connectors of Channel 1 to 5 (
Fig. 14
). The second method is to
place a PROFIBUS standardized plug on the DB9 connector of the specific Channel.

Testing
- If a Channel recognizes valid PROFIBUS messages from one or more connected devices, the RXOK LED of the Channel should be blinking.
According to UL60950-1, if a copper PROFIBUS cable is used outside, it is required to install surge
protection that is suitable for PROFIBUS.
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 (
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 (

use the termination on the DB9 plug and NOT the ProfiHub. This way, the connector can be removed
while maintaining termination on the bus.
When the DB9 connector is used and the cable starts at the ProfiHub, it is recommended to
The ProfiHub B5+ recognizes the transmission speed by default. If it is required that the ProfiHub B5+
is locked to a certain transmission speed, the baudrate switch should be set to the required value (
16
).
Fig.
Fig. 16 - Baudrate speed switch
To set the rotary switch, use a 3 mm screwdriver.
Switch values:
0 = Normal repeating, Auto detect (default)
1 = fixed 9.6 kbps, diagnostics device ON (B5+RD only)
2 = fixed 19.2 kbps, diagnostics device ON (B5+RD only)
3 = fixed 45.45 kbps, diagnostics device ON (B5+RD only)
4 = fixed 93.75 kbps, diagnostics device ON (B5+RD only)
5 = fixed 187.5 kbps, diagnostics device ON (B5+RD only)
6 = fixed 500 kbps, diagnostics device ON (B5+RD only)
7 = fixed 1500 kbps, diagnostics device ON (B5+RD only)
8 = fixed 3000 kbps, diagnostics device ON (B5+RD only)
9 = fixed 6000 kbps, diagnostics device ON (B5+RD only)
A = fixed 12000 kbps, diagnostics device ON (B5+RD only)
B = Robust repeating, Auto detect, diagnostics device ON (B5+RD only)
C = Robust repeating, redundancy on channel 4 and 5, diagnostics device ON (B5+RD only)
D = Robust repeating, diagnostics device ON (B5+RD only)
E .. F = Reserved for future use
Please note that the position of the rotary switch is only sampled during start-up. Changing the
position of the switch will not have effect during operation.
The auto baudrate detect feature will search for the correct baud rate within 10 seconds of receiving
the first telegram. This baud rate lock will be lost after 50 seconds of incorrect or no message
reception.
In robust repeating mode, only messages starting with a valid PROFIBUS start delimiter are repeated
(SD1, SD2, SD3, SD4 and Short Acknowledge). In Normal mode, every bit is transferred immediately
onto the other channels.
To use the Redundancy option of the B5+, set the rotary switch to the ‘C’ position.
This enables the last two channels (4 and 5) to be one redundant path to another B5+, to a redundant
COMbricks, or to any other supporting product. See Fig. 17 for an example.
Fig. 17 - Redundant path between two ProfiHubs
The telegrams are transferred onto both redundant channels. The logic inside the ProfiHub determines
which telegram is used to be transferred onto the other channels. A message received by a redundant
channel is repeated on all other channels, except the other redundant channel. A message received
by a normal channel is repeated on all other channels.
When one redundant cable breaks, the other cable ensures safe delivery of the telegram. In this event
the built-in alarm contact will close. The red ‘ERROR’ LED will blink with an interval of 100ms. When
the redundant path is fixed, press the ‘ALARM RESET’ pushbutton to reset the alarm.
ATTENTION:
Using the ProfiHub B5+ in Redundancy mode causes a delay in processing the telegrams. When used
together with COMbricks in redundancy mode it is required to increase the default MinTSDR in the
PLC busparameters slightly. Recommended is to increase the MinTSDR with a value according to the
Delay Time table, column ‘Robust Mode’, described in the Technical Data chapter.
The B5+ is available with a built-in Diagnostics Device option. The order code for this ProfiHub B5 with
diagnostics device is 17020RD.
The Diagnostics Device is a very versatile statistics/diagnostics logger. It can be used to keep track of
the overall PROFIBUS network health and inform the PLC or DCS of any network failure such as
repeats or illegals, missing ProfiHub termination, live list changes, or power supply problems. Audible
or visible feedback is also possible by automatically switching the integrated alarm relay.
This information can also be read easily with ProfiTrace because the Diagnostic Device sends this
data over PROFIBUS. This enables maintenance engineers to immediately identify the affected
segment in case of cable problems or instrument failure. Having a Diagnostics Device in your network
dramatically decreases downtime because problems can be solved much quicker; it tells you where to
look. SCADA applications can make this even easier.
Fig. 18 – Cable problems or node loss can be identified by the ProfiHub channel, and send this
information over PROFIBUS to the PLC. ProfiTrace can also read this.
The following statistics and events are continuously monitored:
Events: Statistics:
Alarm Relay opened/closed Losts
Cable Redundancy change Syncs
Baudrate change Repeats (total)
Power input changed Repeats (max. changed in 1 cycle)
Termination of Channel changed Illegals
Communication on Channel stopped/started Internal Diagnostics
Livelist changed (station removed or added) External Diagnostics
Diagnostics while in Data Exchange
All of these events and statistics can be transferred in four different ways, so that the PLC/DCS or user
can be warned that something is happening in the PROFIBUS network: a PROFIBUS input message,
a diagnostic message, an external diagnostics message, or it can trigger the built-in alarm relay.
Fig. 19 - Ways of notifying the user in case of problems
3.1 Setting up the Diagnostics Device
3.1.1 Enabling the Diagnostics Device
To enable the Diagnostics Device in the ProfiHub, set the rotary switch on the top left side to any
position from 1 to D (for a complete list of rotary switch settings, refer to the Technical Data chapter).
Next, power-cycle the device by removing power and applying the power again. The rotary switch
position is only read during start-up of the ProfiHub.
3.1.2 Changing the default PROFIBUS address
By default the address of the Diagnostic Device is set to 126. To change the address, use a
configuration tool which supports the ‘Set Slave Address’ command. Most configuration tools support
this feature.
Fig. 20 - ProfiCaptain changes the address from 126 to 20
Locate and download the appropriate GSD file for the Diagnostics Device on
www.procentec.com/downloads . The correct GSD file for the ProfiHub B5+RD is:
PROC6970.gsd. The zip file also contains the corresponding .bmp (Bitmap) files.
Import the GSD file into your configuration tool and insert the device in the PLC
hardware configuration.
3.2 Configuring the Diagnostic Device
The Diagnostic Device has many configuration options. It can be configured modularly. This paragraph
describes all the available options per module in list order.
3.2.1 Info data (mandatory module)
There is only one mandatory module, which is the first module in the list (“INFO DATA MANDATORY

Byte 2: Device type byte (0xB5 is ProfiHub B5+, 0xB2 is ProfiHub B2+)
Byte 3: Version byte: 0x01
Byte 4: Data format byte (0x00 is Little Endian, 0x01 is Big Endian)
3.2.2 Alarm Confirmation
Input Identifier byte: 0x01
The Alarm Confirmation module has one Output, which can be used to reset the alarm. If the Alarm
Relay has been triggered by any event (see paragraph 2.6), it can be reset by the PLC by sending
0x01 or higher to the output of this module.
3.2.3 Redundant Status
Input Identifier byte: 0x10
The next input byte is to indicate the status of the redundant path. It is divided in nibble 0..3 and 4..7.

The Diagnostic Device has many user-definable parameters that can be changed, to alter the
behaviour and options of the ProfiHub Diagnostics Device.
3.3.1 Diagnostics
The Diagnostics Device sends a diagnostic message on PROFIBUS whenever certain conditions are
changed. These changes can be any of the following:
Livelist change (a station added or removed)
Bitrate error
Alarm relay active
Power status changed (one of the two power sources added or removed)
Redundancy status change (one of the redundant cables added or removed)
Termination status change (a termination switch on the ProfiHub has been changed)
Channel status change (communication stopped or started on a channel)
Statistics change (any statistic has changed)
In your configuration tool you can toggle the diagnostics for each item.
Fig. 21 - Screenshot of ProfiCaptain - User Parameter window
th
The 8
byte of a diagnostic message from the Diagnostic Device indicates which options have been
You can choose which Statistics can trigger a diagnostic message, because not all statistics are
interesting in all networks. For example, Syncs have been disabled by default because this is not a
statistic that is suitable for PROFIBUS health monitoring.
Fig. 22 – You can choose which statistics trigger a diagnostic message
The following Statistics can trigger a diagnostic message of the Diagnostic Device:
Illegals changed
Internal Diagnostics changed
External Diagnostics changed
Diagnostics in Data Exchange changed
3.3.3 Extended Diagnostics on Events change
For more critical applications you can choose to enable the ‘Extended
Diagnostics’ option for each of the previously mentioned events. In the
case of such an event, the Diagnostics Device will send out a
diagnostics message with the ‘Extended Diagnostic’ bit on. In a
Busmonitor tool such as ProfiTrace the extended diagnostics bit will
appear as a red blinking square.
All Events described in paragraph 3.3.1 can trigger the Extended Diagnostic bit of the Diagnostic
Device. By default, the Extended Diagnostic option is disabled. Each item can be enabled individually.
The Extended Diagnostic option can also be enabled for each individual available statistic. This works
the same way as the Events described in paragraph 3.3.3.
The Alarm Relay on the ProfiHub can be switched on each Event described in paragraph 3.3.1. When
such an Event occurs, the Relay will be switched immediately without delay. The only Event that can
delay the switching of the Alarm Relay is the Lost event. See paragraph 3.3.8 for an explanation.
3.3.6 Alarm relay on Statistics change
The Alarm Relay on the ProfiHub can be switched (closed) on each change in Statistics, described in
paragraph 3.3.2. When such an (enabled) Statistic change occurs, the Relay will be switched
immediately without delay. The only Statistic that can delay the closing of the Alarm Relay is the Lost
event. See paragraph 3.3.8 for an explanation.
You can change the duration of the Extended Diagnostics warning in steps of 100 milliseconds. The
default value is 10, so 1 second. The maximum value is 255.
3.3.8 Changing the Device Lost timeout
The Diagnostics Device waits for a certain time before it considers a slave to be lost. This works in a
similar way as the ProfiTrace Live List, where the background turns yellow when a slave stops
communicating. This timeout can be changed in steps of 1 second. Default value is 5, and maximum
value is 255.
The data format can be changed if needed. Default is Motorola, high-low-byte format.
You can change it to Intel, low-high-byte format.
3.4 ProfiTrace plugin for the Diagnostic Device
On the download section of www.procentec.com you can download a useful plugin for the Diagnostic
Device. It interprets all messages to and from the Diagnostic Device and displays the data in the Info
Panel of ProfiTrace.
3.4.1 Installing the Plugin
Once you have downloaded the
file and extracted it to your hard
drive, start ProfiTrace and
choose ‘Settings – Plugins’ to
bring up the Plugin window.
Click ‘Install Plugin’ and locate
it on your harddrive.
Next, click ‘Enabled’ so that
ProfiTrace starts the plugin on
startup.
When the Plugin is correctly started and you have a ProfiHub with Diagnostics Device running, click
‘Start Message Recording’ in ProfiTrace, and view the screen with messages (see Fig. 23). If you
click on a data exchange message to or from a Diagnostics Device, you will see all the interpreted
data bytes in the Info Panel. This is very useful for Troubleshooting activities.
A good example is the Statistics. These statistics are available per individual channel or station
address (see paragraph 3.2.10), so it is easy to see the source of the problem.

DP-V2 DP-V2 is the second stage of extension of PROFIBUS DP after DP-V1. DP-
V2 devices shall comply with the following features:
- Data Exchange Broadcast (DxB) for slave to slave communication
(publisher/subscriber principle).
- Isochronous Mode (time tick synchronized operating slaves, e.g. drives)
- Up- and/or download of Load Region Data (domains)
- Clock Control (synchronization within slaves) and Time Stamping
- Redundancy.
Electromagnetic
See EMC.
Compatibility
EMC The extent to which an electric or electronic device will tolerate electrical
interference from other equipment (immunity), and will interfere with other
equipment. Within the European Community as well as in other countries it is
regulated by law that electric and electronic components and equipment
comply with basic standards such as IEC 61000-6-2 or IEC 61326 or
corresponding individual product standards.
Hub A Hub refreshes a signal and passes the information on to all nodes which
are connected to the Hub. Data frames which were received on one port are
transferred to all the other ports (chicken foot topology).
MPI Multiple Protocol Interface. Protocol defined by Siemens which uses the
layer 1 and 2 of PROFIBUS (FDL).
PCB Printed Circuit Board.
PROFIBUS DP Acronym for "PROFIBUS for Decentralized Peripherals". Specification of an
open fieldbus system with the following characteristics:
- Flying masters with robin round token passing coordination (MM)
- Connection based (MS1) and connectionless (MS2, MS3) acyclic
communication between masters and slaves
Options (e.g.):
- Data exchange broadcast (DXB), i.e. slave to slaves communication
- Isochronous mode of slaves
- Clock synchronization
- Redundancy
PROFIBUS DP is standardized within IEC 61158 and IEC 61784,
communication profile families 3/1 and 3/2
The term "PROFIBUS DP" also is a synonym for the RS485 based
deployments within factory automation.
Repeater Active physical layer device that receives and retransmits all signals over a
different port to increase the distance and number of devices for which
signals can be correctly transferred for a given medium.
Spur line A cable attached to a bus segment with a T-connection . Spurs are not
recommended with PROFIBUS DP. They are prohibited with 12 Mbps and
PROFIsafe operations. German term is "Stichleitung".
