1 Introduction
1.1 General
The PROFIBUS Tester 4 is a powerful tool that allows full testing of the bus physics and bus communication on PROFIBUS DP segments.
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 tool is powered either through an external AC adapter, by direct connection to 24 VDC or through an optional portable power supply unit .
1.2 Test Functions
The PROFIBUS Tester 4 automatically detects the baud rate or open circuit voltage as soon as you connect it to a PROFIBUS DP segment.
You can then choose between two modes of operation for bus testing depending on if you run it in stand-alone mode, or connect the PROFIBUS Tester 4 to a PC or notebook. If required the master simulator can be enabled in both modes if no other master is acti ve.
1.2.1 Stand-alone mode of operation
In the stand-alone mode three test functions with simultaneous analysis of bus physics and bus communication are available:
1. The Live Stat us shows the bus status and the details of the analysis in real-time on the display.
2. To evaluate the bus health up to ten Quick Tests can be executed, stored internally and imported by the PC software then.
3. To locate the causes of sporadic bus faults the long-term Trend logs data for up to 41 days and stores them internally for later import by the PC software.
BC-600-PB Introduction
Softing Page 7
1.2.2 PC mode of operation
The PC software provides many additional features for performing, analyzing and managing bus tests. Quick Tests and Trends stored in the tool can be imported.
In the PC mode four main functions are available. Two of them provide complex functionality that only experts need and that are accessed separately from the standard functionality.
Standard functions:
1. The Network Status is a collection of information and test data relating to a PROFIBUS network. It provides the basis for a comprehensive evaluation of the bus health.
o Quick test and user-controlled test with simultaneous analysis
of bus physics and bus communication
o Topology scan o Test report o Master simulator
2. If sporadic faults occur in a PROFIBUS installation, the quality indexes and critical protocol events should be monitored with the long-term Trend over a prolonged period to locate the causes of bus problems.
Expert functions:
3. The function Frames enables the classic frame analysis.
4. The Oscilloscope permits the detail analysis of signal waveforms.

3 Opt i onal Accessories
3.1 D-sub adapter cable for testing live systems
This D-sub adapter cable is optimized for reduced influence on live PROFIBUS DP segment operation. Thereby it is most suitable for testing of running plants. The risk of critical influences on bus operation which can cause a plant standstill is significantly reduced. Attention: Using this cable it is not possible to use the both active functions master simulator and topology detection (see page 23
).

3.3 Fieldbus Shield Digital Leakage Current Clamp
When routing PROFIBUS cables in high-interference environments, electromagnetic interference can affect the signal quality. By measuring the shield currents with the digital leakage current clamp, you can locate EMC problem areas and take appropriate countermeasures. The digital leakage current clamp is supplied in a handy case, including measuring cables. There is also an empty compartment for the fieldbus shield digital leakage current clamp in the carrying case of the BC-600-PB.

3.5 Service Interface for PROFIBUS DP
3.5.1 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 o r 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 an 90° angled PROFIBUS connector with a switchabl e terminating resistor.

5 Pow er Suppl y and Auto Power On
The tool is powered with 24 VDC either through the external AC adapter or by using the single-ended cable for direct 24 VDC power supply. Both are included in delivery.
Attention: Before being connected to the AC mains power, the PROFIBUS Tester 4 and the AC adapter must be acclimated to room temperature to avoid condensati on. This may take up to 60 minutes.
The tool switches on automatically when you connect it to a power supply. The display lights up and self-test starts.
Attention: When the tool is connected directly to 24 VDC, there is no galvanic isolation to the external power supply. Insufficient potential equalization between the power supply and the PROFIBUS will lead to equalizing currents which can falsify the test results and, in the worst case, even destroy the PROFIBUS Tester 4 and part of the bus installation. In these cases, use of the supplied AC adapter is mandatory for operating the PROFIB US Tester 4.
On completion of initial setup, the PROFIBUS Tester 4 displays the following dialog in English:
You can now select the desired display language. The following languages are available: German, English, Frenc h, Italian, Polish and Spanish.
5.1 Power-Up Behaviour without USB Connection
The PROFIBUS Tester 4 starts up in stand-alone mode in this case (see page 26
) and is immediately ready for test i ng.

Softing Page 15
5.2 Power-Up Behaviour when USB Connected
Attention: The “PROFIBUS Diagnostics Suite” PC software also includes the required USB driver. You therefore need to install the software first before connecting the test tool to the PC or notebook.
On successful completion of the self-test, the PROFIBUS Tester 4 displays:
Fig. 9: Power-up display when USB connected
When you start the PROFIBUS Diagnostics Suite control and evaluation software on your computer and select the PROFIBUS Tester and a network for testing in its user interface, the test tool switches to PC mode. The display shows:
Fig. 10: Display at testing with PC software
While in PC mode, you can only display readings and operate the tool by using the control and evaluation software on the computer.
At this point, you can also start a firmware update instead of using the control and evaluation software. See page 38
.
Software Installation Manual
Page 16 © 2013
6 Software Installation
The “PROFIBUS Diagnostics Suite” PC software is provided on the included CD-ROM. You need administrator privileges to install the software. If the CD­ROM does not start automatically when inserted, please run the “start.exe” file in the main directory.
Future updates can be downloaded from our web site at industrial.softing.com
.
Attention: The “PROFIBUS Diagnostic Suite” PC software also includes the required USB driver. You therefore need to install the software first before connecting the test tool to the PC or notebook.
The installation and basic use of the PC software is described in the separate PROFIBUS Diagnostics Suite – Getting Started manual.
6.1 Connection to a PC
Use the included USB cable to connect the tool to a PC or notebook. Power is also supplied from the USB interface.
Attention: It is recommended to connect the unit directly to a USB port on the PC or notebook. When you use external USB hubs or notebook docking stations for conne ct ion, problems can occur.
7 Connection to PROFIBUS
7.1 Basics
7.1.1 Warning notice for testing a live bus Attention: 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!
BC-600-PB Connection to PROFIBUS
Softing Page 17
7.1.2 Connection types
There are several ways to connect a bus station to a PROFIBUS network:
Using connectors o D-sub connectors, most of which have an integrated terminating
resistor and, optionally, an addi tional service socket
o M12 connectors fo r environments requiring increased IP ratings o Special vendor-specific hybrid connectors; they are used in
combination with special cables t o supply power via the bus
Using terminals for direct conne ct i on
Due to the typical daisy-chain topology, the connection points of the bus stations are the only possible points for connecting the test tool in most cases.
7.1.3 Adapter cable
The PROFIBUS Tester 4 is supplied with the D-sub adapter cable BC-600-PB­CB-DSUB-2 „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 av ai l abl e, see on page 9
.
Attention: Use only the short original 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:
Fig. 11: Unallowed cascading of D-sub connectors
Active connection cables with integrated repeaters, such as Softing's BC-131­PB, cannot be used for testing.
Connection to PROFIBUS Manual
Page 18 © 2013
7.1.4 Strain relief
Attention: When you connect the PROFIBUS Tester 4, its weight can place a high mechanical stress on the connectors and the bus station. 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.
Fig. 12: Strain relief fitt i ngs
7.1.5 Test locations
The PROFIBUS Tester 4 can basically carry out tests anywhere on a physical PROFIBUS segment. Please note that the use of repeaters creates separate physical segments that each need to be measured individually.
For the best and most informative results, perform the tests at the beginni ng and end of each physical segment. If these test results indicate pro bl em s t hat cannot be clearly classified right away , you should carry out one or more additional tests at the centre.
BC-600-PB Connection to PROFIBUS
Softing Page 19
7.2 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 4 at that socket (see figure below). If a D-sub connector does not provide a service socket, you can plug in the D-sub adapter cable underneath. The only thing you need to keep in mind is that you should never cascade more than two D-sub connectors (see page 17
).
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 end of the bus by using the terminating resistor provided with the M12 adapter set.
Attention: All these simple connection types will divide the bus. You therefore need to shut down the PLC and all the devices connected to the PROFIBUS; in other words, you need to shut down the whole installation.

7.3 Connection for Testing a Live Bus
To test a live PROFIBUS with the PROFIBUS Tester 4 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.
Attention: When installing additional connection points, you divide the bus. Before doing so, you therefore need to shut down the PLC and all the devices connected to the PROFIBUS; in other words, you need to shut down the whole installation.
Attention: For testing on live systems the optional D-sub adapter cable BC-600-PB-CB-DSUB-1 with reduced influence on bus operation is highly recommended! See page 9
.

7.3.3 Connection via M12 connector
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.

7.4 Master Simulator and Topology Scan
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.
Connection to PROFIBUS Manual
Page 24 © 2013
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.
Both 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 4. The bus termination in the device connector will then be powered by the PROFIBUS Tester 4.

Attention: Bus stations must only be disconnected from the power supply or the bus during shutdown of t he i nst al lation.
Attention: The two functions can be started also when the PROFIBUS Tester 4 is disconnected from the bus. If you then connect the PROFIBUS Tester 4 to a live bus despite the yellow bus status bar indicated by the PC software, this can cause bus communication problems or a shutdown of the installation.
7.4.1 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:
Additionally switch on the terminating resistor in the D-sub
connector of the last slave. The outgoing cable to the active device at the bus end has to be connected to the outgoing connector (marked with “OUT”, an o utgoing arrow, or “A2/B2”).
Fig. 18: Checking the connect ion direction at the D-sub connector
2. When using M12 connection:
The cable from the bus start or test tool has to be connected to
the incoming M12 connector of the last slave. A bus termination is required at the outgoing M12 connector of the last slave.
Display and Control in Stand-Alone Mode Manual

8.3 Functions
8.3.1 Live Status function
The Live Status function very quickly gives you an overview of the bus status. Even transient disturbances during the test are reliably detected. Once you start the function, the tool determines and continuously updates the status for the segment and for each bus station.
8.3.1.1 Bus status summary
Fig. 21: Live Status with bus status summary
Line 1 shows the overall bus status. It results from the substatus for bus communication and the substatus for bus physics, which are displayed in lines 2 and 3.
Bus communication:
1. “Error”
Bus stations were dropped or added during the test
Configuration errors or parameter errors occurred
(the actual structure of modular slaves differs from the configuration stored in the PLC, or an in correct GSD file was used)
2. „Warning“
Frame errors, retries or diagnostics occurred during the test
One or more bus stations have not been configured in the PLC
3. „OK“
No critical states or events
Display and Control in Stand-Alone Mode Manual
Page 30 © 2013
Bus physics:
1. “Error”
One or more bus stations failed to respond during the last physical
test cycle
2. „Warning“
One or more quality indexes* are below the user-defined limit
value (default: 2500)
3. „OK“
All quality index* results are above the limit value
* .. See the “Interpretation of the signal quali ty test results” chapter in the PROFIBUS Diagnostics Suite manual.

8.3.1.2 Segment status 1
Fig. 22: Live Status with segment status 1
To the right of “DP Segm.” in line 1, the display shows changes in the live list (added and dropped bus stations). The following displays are possible:
1. The number of bus stations has not changed during the test:
No display of live list changes
2. One or more bus stations have been added during the test:
“+” display
3. One or more bus stations have been dropped during the test:
“-” display
4. One or more bus stations have been added and one or more dropped
during the test:
“+ -” display
The live list should usually not change when a PROFIBUS system is stable. In line 2, you see the number of masters (M) and slaves (S). For the slaves,
the first figure indicates the number of slaves addressed by the master(s). If not all slaves respond, the number of slaves that failed to respond is indicated after a “-” sign.
Line 3 indicates the token rotation time. Note: The token rotation time does not necessarily equal the bus cycle time.

8.3.1.3 Segment status 2
Fig. 23: Live Status with segment status 2
Line 1 is the same as for segment status 1. In line 2 you see, on the left, the number of retries on the entire segment and,
on the right, the worst quality index of all bus stations. Line 3 shows, on the left, the number of frame errors on the entire segment
and, on the right, the best quality index of all bus stations.

8.3.1.4 Station status This function displays the station status for each bus station, i.e. for all masters
and all slaves.
Fig. 24: Live Status with station status of a master
Fig. 25: Live Status with station status of a slave
The PROFIBUS address of the bus station is displayed right after “DP#” on the left of line 1. The letter in the middle indicates whether the device is a mas ter (M) or slave (S). If the letter is enclosed in square brackets, the BC-600-PB was able to determine the address of the PROFIBUS device to which it is connected. In the above example, the test tool is connected to the device with the address 11 (see Fehler! Verweisquelle konnte nicht gefunden werden.). On the right, you see the live list changes (see page 31
) for this bus
station. Line 2 shows the number of retries on the left, and the worst quality index of
this bus station on the right. Line 3 indicates the number of diagnostics on the left, and the best quality
index of this bus station on the right. Note: The update rate for the live status substantially depends on the number
of bus stations and the signal quality.

8.3.2 Quick Test function
The Quick Test allows full testing of bus physics and bus communication. The test data is stored in the tool. It can subsequently be imported by the PROFIBUS Diagnostics Suite software application.
To start the function, choose one of 10 internal memory locations. The display indicates if the selected memory location is allocated or free. If you select an allocated memory location, t he prev i ous test data will be overwritten.
Fig. 26: Quick test complet ed
The duration of a Quick Test depends on the baud rate, the number of slaves and the current bus communication. It can take only a few seconds or up to three minutes.
On completion of the test, press the acknowledgment key to cancel the status display.

Softing Page 35
8.3.3 Trend function
Trend logging is used for detecting rare or sporadic faults over a prolonged period of time. The function monitors both the bus physics and critical events in the bus communication. The PROFIBUS Tester 4 can automatically test the bus in stand-alone mode from within the control cabinet for up to 41 days. The test data is stored in the tool. It can subsequently be imported by the PROFIBUS Diagnostics Suite software application.
Before you start the function, choose a test interval. When you select “Auto” the tool automatically determines the optimum interval. The Trend Test runs until manually stopped with the “x ” key .
Fig. 27: Trend running for 23 h and 52 min.
The test is aborted automatically when the power supply is interrupted (all data logged so far is retained in memory) or when the maximum logging time of 999 hours and 59 minutes is reached.

Quick Tests and Trend logs stored in the test tool can be imported into the PC software. To do this, start the PROFIBUS Diagnostics Suite. If a PROFIBUS Tester is connected to the PC via USB and contains stored test data, an additional “Import Test Data f rom T ool” dialog box appears automat icall y.
Fig. 28: Importing test data
For ALL the stored data, you need to fully select the action to be performed, the network/project, and the test location to which you want to store the data. The default action “Import & Delete“ deletes the test data in the tool after the import is complete. This frees the allocated memory locations for new tests.
The imported Quick Tests and Trend logs are fully compatible with the test data that can be acquired using the PC software.

12 Troubleshooting
Problem
Causes and remedies
The display of the PROFIBUS Tester 4 remains blank.
Possible cause:
The PROFIBUS Tester 4 always needs an additional external power supply.
Remedy:
Use the supplied external AC adapter to connect the tool to the mains power supply.
When connected directly to a 24 VDC power supply: check the voltage at the terminals
Alternative cause:
The tool is defective.
Remedy:
Return the tool for servicing (see page 39)
The display shows the
following error message: “USB ERROR - Refer to manual or disconn. for stand­alone mode”.
Possible cause:
This error message can be caused by poor physical connection via USB (“loose” contact).
Remedy:
Check the USB cable and connector.
The baud rate is not detected
automatically on a live PROFIBUS.
Possible cause:
Massive disturbances in the bus physics.
Remedy:
Manually set the baud rate and repeat the test.
If you need to contact Softing's support team, you will find the contact data on the back cover of the manual.
