Introduction
1.1
About PROFIBUS Tester 5 BC-700-PB
The PROFIBUS Tester 5 BC-700-PB is a powerful tool that allows full testing of the bus
physics and bus communication on PROFIBUS DP and PROFIBUS PA segments
(option). Using the integrated master simulator, you can also test the bus physics if the
PLC is currently not in operation, or individually check "suspicious" bus stations. The cable
test function examines the cabling in PROFIBUS DP segments, locates unwanted
reflections on the line and verifies proper termination of cable segments. The tool is
powered either by its built-in battery or through an external AC adapter.
The PROFIBUS Tester 5 BC-700-PB is the first battery-powered tester, which combines
the assessment of bus physics and bus communication as well as cable testing in one
device. It is therefore the only and truly mobile PROFIBUS diagnostic tool.

Service interfaces for PROFIBUS DP
1.4.6.1 Connection type D-sub
The D-sub service interface provides a PROFIBUS access point for testing if the existing
D-sub connectors have no service socket or if the bus stations are connected via a
terminal block. The service interface can power the terminating resistor of the D-sub
connector. You can thus use it as an active bus termination at the beginning or end of the
bus.
If the PLC allows dropping and adding bus stations on the live bus, you will need this
external bus termination to be able to exchange the first and last bus stations without
causing problems on the bus.
The compact unit is rail mounted like a terminal block and powered by an external 24 VDC
power supply. The package includes a 90° angled PROFIBUS connector with a
switchable terminating resistor.

General information
6.1.1
Possible side effects when testing a live bus
Test tool side effects
When you connect a test tool, side effects on the system under test are
generally unavoidable. If the PROFIBUS is already disturbed to a certain
degree or if Simatic Diagnostic Repeaters are used, the operation of the
PROFIBUS might nevertheless be affected occasionally. Compliance with
the connection notes is mandatory.
6.1.2
Connection types
You can connect a bus station to a PROFIBUS network either
using connectors such as
o
D-sub connectors 25 , most of which have an integrated terminating resistor and,
optionally, an additional service socket
o
M12 connectors
o
Special vendor-specific hybrid connectors; they are used in combination with
special cables to supply power via the bus
13
for environments requiring increased IP ratings
or
using terminals for direct connection.
Due to the daisy-chain topology, the connection points of the bus stations are the typical
points for connecting the test tool.
PROFIBUS Tester BC-700-PB - User Manual
21
Chapter 6 - Connection to PROFIBUS
6.1.3
Adapter cable
The PROFIBUS Tester 5 is supplied with the D-sub adapter cable BC 600-PB-CB-DSUB2 „Standard" (light connector). For testing on live systems the optional D-sub adapter
cable BC-600-PB-CB-DSUB-2 is recommended. An M12 adapter set is optionally
available, see D-sub adapter cable for testing live systems 9 .
Only use original short cables
Only use the original short cables with special pin layout to connect the unit
to a PROFIBUS network.
Do not cascade more than two D-sub connectors with service sockets at
the same time!
Figure 15: Unallowed cascading of D-sub connectors
6.1.4
Strain relief
Use the strain relief supplied with the test tool. Thus you avoid the device from falling
down.
Figure 16: Recommended use of retaining strap
22
PROFIBUS Tester BC-700-PB - User Manual
Chapter 6 - Connection to PROFIBUS
Avoid stress on connectors and bus stations
Avoid stress on connectors and bus stations which might be caused by the
device's own weight. Ensure proper strain relief by using suitable supports,
cable ties, etc. When this is not possible, you need to select a different
connection point to avoid damage.
6.1.5
Using the security lock port
When using trend logging, the PROFIBUS Tester 5 is typically operated in an unattended
manner over a prolonged period of time. You can connect a Kensington lock to the
security lock port to prevent your device being stolen. The Kensington lock is not part of
the product delivery. To use this feature, you have to purchase the Kensington lock
additionally. To use the Kensington lock, refer to the product manual. Tie the Kensington
lock cable to a fixed object and install the other end of the cable to the security lock port.
Figure 17: Using a Kensington lock
6.1.6
Test locations
The PROFIBUS Tester 5 can basically carry out tests anywhere on a physical PROFIBUS
segment. Note that the use of repeaters creates separate physical segments that each
needs to be measured individually. For the best and most informative results, perform the
tests at the beginning and at the end of each physical segment. If these test results
indicate problems that cannot be clearly classified right away, you should carry out one or
more additional tests at the center.
6.2
Simple connection for tests during system shutdown
If all bus stations provide D-sub connectors with an additional service socket, you can
simply plug in the PROFIBUS Tester 5 at that socket (see figure below). If a D-sub
PROFIBUS Tester BC-700-PB - User Manual
23
Chapter 6 - Connection to PROFIBUS
connector does not provide a service socket, you can plug in the D sub adapter cable
underneath. Keep in mind that you should never cascade more than two D-sub
connectors (see also Adapter cable 22 ).
When using M12 connection technology, the M12 adapter cable is "looped" into the bus. It
is essential to ensure proper termination at the beginning and at the end of the bus by
using the terminating resistor provided with the M12 adapter set.
Shut down complete installation before connecting
Shut down the PLC and all the devices connected to the PROFIBUS as all
these simple connection types will divide the bus.
Figure 18: Connection points at system shutdown
6.3
Connection for testing a live bus (DP)
To test a live PROFIBUS with the PROFIBUS Tester 5 during operation, appropriate
connection possibilities have to be provided. If no suitable connection points are available
in the existing installation, it is recommended to install them during system shutdown. This
will make future maintenance work much easier.

Tests on a live PROFIBUS are only allowed on bus segments providing D-sub connection
technology. Only D-sub connectors with service socket can be used as connection points
for the test tool. For this reason, tests can often only be performed at a bus end.
Figure 21: Connection points for the M12 adapter cable
Connect T-fitting between existing cable and 1 meter connection
cable
Always connect one end of the T-fitting to the already existing cable and the
other end to the 1 meter connection cable which is supplied with the service
interface.
Do not screw the T-fitting of the M12 service interface directly onto a slave.

Master simulator, topology scan and cable test
Master simulator
The master simulator allows checking the bus cabling and the station addresses during
installation and commissioning, when the PLC (master) is not in operation yet. In addition,
you can use this mode to check individual "suspicious" bus stations that have been
disconnected from the bus.
PROFIBUS Tester BC-700-PB - User Manual

Chapter 6 - Connection to PROFIBUS
Topology scan
The topology scan determines the sequence and distances of all passive bus stations
(slaves). This feature requires correct bus cabling, a very good signal quality, and a
connection point located directly at the beginning or end of the bus.
Cable test
The cable test assesses the wiring and can be used to determine a faulty cable location
(e.g. short circuit) by means of reflection test.
All three features can only be used during shutdown of the installation. The D-sub cable
BC-600-PB-CB-DSUB-2 which is included in the standard scope of supply must be used.
As long as communication is detected on the bus, i.e. at least one device is an active
master, the functions are disabled. If necessary, disconnect every single active device
(PLC, MPI and, if necessary, diagnostic repeaters) from the power supply or the bus. If an
active device is at the end of the bus you want to test, its PROFIBUS connector needs to
be unplugged and connected directly to the PROFIBUS Tester 5 BC-700-PB. The bus
termination in the device connector will then be powered by the PROFIBUS Tester 5 BC700-PB.

Bus stations must only be disconnected from the power supply or the bus
during shutdown of the installation

PROFIBUS Tester BC-700-PB - User Manual
Chapter 6 - Connection to PROFIBUS
The three functions can be started also when the PROFIBUS Tester 5 BC700-PB is disconnected from the bus. If you then connect the test device to
a live bus, this can cause bus communication problems or a shutdown of
the installation.
Special case: Active devices at both ends of the bus
On the very rare occasion when there is an active device at each end of the bus, do the
following:
1.
When using D-sub connection:
a.
Additionally switch on the terminating resistor in the D-sub connector of the last
slave.
b.
Make sure the outgoing cable to the active device at the bus end is connected to
the outgoing connector (marked with "OUT", an outgoing arrow, or "A2/B2").
Figure 23: Checking the connection direction at the D-sub connector
2.
When using M12 connection:
a.
Connect the cable from the bus start or test tool to the incoming M12 connector
of the last slave.
b.
A bus termination is required at the outgoing M12 connector of the last slave.

Connecting to PROFIBUS-PA networks
6.5.1
Test locations
There are several ways to connect bus stations to PROFIBUS PA:
Using terminals for direct connection
Using M12 connectors in the field (unfortunately there is no rule defining on which
sides the male and female connectors are to be used)
Field distributors and T pieces are widely used. As opposed to PROFIBUS DP, spur
cables are allowed to a limited extent for PROFIBUS PA.
The following types of DP/PA fieldbus couplers are the most common:
Simatic DP/PA couplers from Siemens, also as part of DP/PA links
PROFIBUS Tester BC-700-PB - User Manual
29
Chapter 6 - Connection to PROFIBUS
SK1, SK2 and SK3 segment couplers, e.g. from Pepperl+Fuchs (or sometimes under
a different label)
Irrespective of the connection types used for the field devices, the fieldbus couplers are
usually installed in a control cabinet, and the PA output is connected there via terminals.
Connection to MBP-IS is not allowed.
You can use the connection points of bus stations or access points inside the field
distributors as connection points. Establishing the electrical connections required for
measuring may vary from system to system and might not be possible during operation.
Figure 24: Connection points for PROFIBUS PA
Hint
An appropriate connection point is located directly at the DP/PA coupler. At
this point, the tool can continue to analyze the bus communication even
when lines are interrupted. The measurements are not affected by repeaters
or field barriers.

6.5.2
Requirements for analyzing a live bus
When using the PROFIBUS Tester 5 and the BC-700-H1 adapter to carry out
measurements on an MBP segment during operation, it is preferable to connect the tool
via free bus connection terminals of the DP/PA fieldbus coupler. If the bus begins at the
coupler, you can simply use the second terminal block at the DP/PA coupler or at the SK1
or SK2 to sample the bus signal. If the couplers mentioned above are not located at the
beginning of the bus or if the bus begins with an SG3 coupler or if you are interested in the
PROFIBUS PA signal at another test location, we recommend connecting a short spur
cable to rail mounted terminals during system shutdown. This gives you an appropriate
connection point and makes future maintenance work much easier.
6.5.3
Analyzing during system shutdown
If there is no possibility for connection, you need to improvise in order to pick up the bus
signal at an existing terminal block of the fieldbus coupler, the field distributor, segment
protector or a field device. For example, you can try a double assignment of bus terminals.
Shut down the system before you divide the bus.
Disconnect all bus stations from the power supply.
6.5.4
Bus connection
The supplied test equipment set allows to easily connect the BC-700-H1 adapter to the
PROFIBUS PA segment. Alternatively you can use a short length of PROFIBUS PA
standard cable to connect the tool to the bus.
Figure 25: PROFIBUS-PA pin assigment
Do not use in hazardous areas
The PROFIBUS Tester 5 and BC-700-H1 adapter must not be used in
hazardous areas and must not be connected to an intrinsically safe MBP-IS
segment (blue terminals of fieldbus coupler; in some cases blue bus
cables).

The signal quality test determines the signal quality index
for each bus station and displays the test result in a bar
diagram. The test location is particularly important when
you are testing the signal quality.
Additional information is available such as Signal/ Noise
ratio, edges and numerical values with respect to signal
quality testing.
The test location is particularly important when you are
testing the signal quality. It is recommended to make at
least two signal quality tests per physical segment (at
both ends of the corresponding segment).
The signal quality evaluation settings contain limit values
for the quality index, signal/noise ratio, rise time and
timeout.
The cable test function examines the cabling in
PROFIBUS segments. This test detects the cable
segment length, scans for unwanted reflections on the
line and verifies proper termination of the cable. In case
of a fault you will get an error description and a distance
indication (if possible) for troubleshooting actions. Tests
regarding cabling can only be made from one end of the
PROFIBUS line. Active stations (Masters, MPI panel,...)
must be disconnected during testing of the respective
cable segment.
For further information and starting points in order to
correctly interprete the fault indication see List of fault
indications and remedial measures 48 .
In the context of cable testing it is recommended to
provide additional information about the corresponding
cable segment (physical segment). This is important for
proper detection of line length, compliance with
maximum allowed segment length as well as for proper
documentation of test results. Please give full particulars
with respect to the configuration of each cable segment.

Organize and store test results
PROFIBUS Tester 5 comprises three predefined network folders: a default network folder
and two empty folders.
A network folder is a directory containing all the test results assigned to a network. The
name of the network folder is the same as the network name displayed during the data
import into the PC.
The default network is provided for spontaneous tests and is a fixed component of the
project management and cannot be deleted. However, you can rename and edit the
default network and start testing using this network. If you are deleting all networks,
automatically the default network including a default segment and a default test location
will be generated in the network folder.
A network in PROFIBUS Tester 5 comprises one or more segments, and one or more
test locations. A minimum network configuration (default network) comprises one
segment (default segment) and one test location (default test location).
The test location has a major influence on the test result, particularly when testing signal
quality, using the oscilloscope function or using the cable test function. To store all test
results within a network in the PROFIBUS Tester 5, you have to set the radio button to the
corresponding network in the networks function (see also User interface 32 ).
Figure 29: Select Network – the radio button is set to "engine production"
Test results in stand-alone mode are stored under the specified test location in the
network you have defined as the storage location. Thus, test results will be organized and
stored in PROFIBUS Tester 5 according to their test location. Refer to the figure below to

Tips and tricks for cable testing
Perform cable test without mains adapter
When using the cable test function we recommend removing the mains
adapter and operating on the PROFIBUS-Tester 5 by means of the built-in
battery in stand-alone operation mode.
13.1
Assessment criteria
The cable test function examines the cabling in PROFIBUS DP segments and
summarizes the test result in a single statement ("Ok" or "Error"). Amongst technical
criteria with respect to the cabling the overall assessment incorporates additional criteria
with respect to the workflow and to plant planning. Under certain conditions a user may not
be able to successfully finish cable testing in a dedicated segment (e.g. at a very early
installation phase of a facility, when there is no possibility to power the bus terminators). In
such a case it is recommended, to add a comment to the corresponding test report which
clarifies the circumstances that lead to the negative cable test result. Not all errors will
inevitably lead to downtimes or represent under the specific circumstances a severe error.
At last, the commissioner or maintenance personnel decides, if a PROFIBUS-network is
functioning properly or not. The corresponding person gets necessary information and
recommendations by means of using appropriate PROFIBUS diagnostic tools. The table
below contains assessment criteria which must be fulfilled in order to successfully
complete the cable testing function. The table describes also, under which conditions the
cable test will result in an error or failure.
Failed, if at least one of the following
criteria is fulfilled
Substatial troubleshooting effort was
carried out unsuccessfully and there are
still errors on the cabling
The corresponding PROFIBUS DP
segment is still affected by reflections on
the cable
The user did not run through the tree steps
of cable testing
Detection of the cable segment length fails
Bus termination is not as expected
The detected cable segment length
exceeds the limit value specified by PI
(PROFIBUS PROFINET International)
PROFIBUS Tester BC-700-PB - User Manual
Passed, if all of the following criteria
are fulfilled
All cabling errors have been successfully
eliminated
The corresponding PROFIBUS DP cable
segment is free of reflections
The user has run through each of the three
steps of cable testing successfully
The cable segment length has been
successfully detected
The terminators at both ends of the cable
segment are switched on and properly
powered

List of fault indications and remedial measures
The classifying text messages in the graphical user interface of PROFIBUS Tester 5
which describe the cabling errors are kept concisely. The table below lists possible
cabling error messages and provides a detailed description of the discovered fault
indications. The column on the right contains "remedial measures" and further starting
points in order to correctly interpret and to repair the indicated fault.
The PROFIBUS Tester 5 uses amongst other methods impulse reflectometry for
assessing the cabling and classifying and locating errors on the cable. Multiple cable
errors, which exist simultaneously on the cable may result in an imprecise cable test
result. Please bear in mind, the more the corrective repair of the cable is proceeding, the
more precise the cable test results in the corresponding PROFIBUS cable segment will
be.
Electromagnetic interferences may influence PROFIBUS cable testing in a negative
manner because cable conductors may act like an antenna. Please bear this in mind
during cable testing and take care of proper functional earthing of your plant respectively.
Existing high frequency noise voltage may negatively influence the PROFIBUS Tester 5 if
operated by means of the external power supply. We recommend operating on the
PROFIBUS-Tester 5 by means of the built-in battery under the above mentioned prevailing
conditions.

Break on line A
The green signal line of the PROFIBUS-cable is broken. Please
search for damage on the cable in the vicinity of the indicated
error location. Possibly the error could come from a fatigue
breakage or a faultily assembled PROFIBUS-connector. The
green signal line typically is connected to Pin 8 of the
PROFIBUS Sub-D type connector.
The red signal line of the PROFIBUS-cable is broken. Please
search for damage on the cable in the vicinity of the indicated
error location. Possibly the error could come from a fatigue
breakage or a faultily assembled PROFIBUS-connector. The
red signal line typically is connected to Pin 3 of the PROFIBUS
Sub-D type connector.
The shielding conductor is broken in the tested cable segment.
Alternatively electromagnetic shielding is not applied for in a
continuous manner. Please search for damage on the cable in

Idle voltage too high
The ideal idle voltage between signal wires A and B of a cable
segment, which is properly terminated on both sides is
approximately 1.1 Volts. However, the PROFIBUS-Tester
detected voltage values higher than 3 Volts between the signal
wires A-B; A-Shield and/or B-Shield. These unwanted potential
differences obstruct the cable testing function and the test
results will become void. Plus, running leakage currents may
damage the PROFIBUS-Tester.
Please take care of proper functional earthing of your plant.
We recommend to remove the mains adapter and to operate
on the PROFIBUS-Tester 5 by means of the built-in battery if
you are receiving this error message. This will avoid damage
caused by leakage currents.
Please take also into consideration that the error cause could
be a defective RS-485 driver of a PROFIBUS-device.
Troubleshooting EMC and earthing issues are a highly complex
field of activity. Therefore it is recommended to ask service
providers which are primarily specialized in troubleshooting the
above mentioned issues.
Far-end / Near-end
The corresponding bus terminator has been switched on, but
terminator not powered the terminator is improperly powered by 5 V supply voltage, yet.
During the cable testing the PROFIBUS Tester requires a
properly terminated cable at the far end (2nd test step) or on
both sides of the cable segment (3rd test step). A properly
terminated cable segment consists of activated and powered
bus terminators on both sides of the cable.
Please make sure that the corresponding PROFIBUS-device at
the corresponding end of the cable segment is powered. Plus,
the activated bus terminator is properly plugged to a powered
PROFIBUS-device.
No terminator detected There is neither an unpowered bus terminator nor there was
detected a bus terminator at all in the respective cable
segment.
During the cable testing the PROFIBUS Tester requires a
properly terminated cable at the far end (2nd test step) or on

When using D-sub connection, activated bus terminators are
only effective at the incoming connector of PROFIBUSconnectors. The incoming connector is marked with "IN", an
incoming arrow or "A1/B1". Please be also on the lookout for
PROFIBUS-cables which have been connected by mistake to
the outgoing connector.

Far-end / Near-end
The PROFIBUS Tester detects an ohmic resistance between
terminator wrong or not the signal wires A and B, but the resistance value is not as
adapted
expected in the range of a bus terminator.
Please make sure, that the bus terminator is properly powered
and the PROFIBUS-connector has been properly powered.
Take into consideration that multiple bus terminators may be
switched on and that dip-switches for switching on/off bus
terminators may be defective (due to aging and soiling).
Line A and B
The green and the red signal line are interchanged. Possible
interchanged
cause might be a PROFIBUS connector which is assembled
improperly. Please bear in mind that after having two times
interchanged line A and B, this error cannot be recognized
anymore. Only when interchanging both lines for a third time,
you may recognize the error.
Typically, the tester will not return a measured distance. In
order to localize the fault location we recommend shortening
the respective cable segment step by step by switching on bus
terminators within the cable segment.
Repeat the cable test after each shortening procedure until the
error is no longer reported.
The last active bus terminator is the faulty one.

internal 5 V power
resistor has been switched on at the test location but is not

powered via a PROFIBUS station. Possible causes: The
related cable end is not connected to an activated PROFIBUS
station or the 5 V power supply of the related PROFIBUS
station is defective. The PROFIBUS tester was able to supply
the bus terminating resistor with its tester-internal 5 V power
supply.
13.3
Metering the cable segment length correctly
Directly after starting the cable test function you will see the actual segment configuration.
In the context of cable testing it is recommended to provide the number of connectors and
connected devices in the respective cable segment. The provided number of these
elements should be as precise as possible in order to correctly detect cable segment
length or the distance to the error. This chapter illustrates, how connectors and devices
influence the detection of the cable length.
Connectors: Please specify, how many 12 MBit/s PROFIBUS-connectors exist in the
respective cable segment and enter the number in the segment configuration. The series
inductance within the 12 MBit/s PROFIBUS-connectors act like a delay element on the
cable with respect to impulse reflectometry. Every connector corresponds to approx. 50
cm cable length.
PROFIBUS Tester BC-700-PB - User Manual
51
Chapter 13 - Tips and tricks for cable testing
Devices: Please specify, how many PROFIBUS devices are connected to the respective
cable segment (Master, Slave, repeater; typ. not more than 32). The RS485-driver unit of
each PROFIBUS-station acts like a RC-cicuit (delay element) on the cable. In the context
of impulse reflectometry this corresponds to additional 20 cm cable length per device.
Consequently, the combination consisting of connector plus device corresponds to
approx. 70 cm cable length.
Example: A cable segment has approx. 50 m effective cable length and contains 20
PROFIBUS devices, which are connected to the line by means of 12 MBit/s Sub-D type
connectors. Without indicating the number of connectors and devices the PROFIBUS
Tester 5 BC-700-PB will detect a total cable segment length of 64 meters, which
corresponds to a systematic error of measurement of approx. 28 %. The more precise
you will enter the number of connectors and devices into the segment configuration, the
more precise the length indication will be (cable segment length or distance to error).
The cable length detection is optimized for standard PROFIBUS cable type A. The
detected cable segment length will show a methodical error in measurement, if you are
using a fieldbus cable with deviating impedance value.
