We have documented the answers to the most frequently asked questions to enable you to easily and quickly find answers directly.
There are two types of licenses:
To use all TH SCOPE features you will need to acquire a license.
With the installation of TH SCOPE you will automatically have a 30-day demo license.
Please note, that if you don't have a valid license or the demo mode is over then several tabs are not available in the TH SCOPE Link View. Without a valid license the tabs "Topology", "Trend", "Reference" und "Export" are not visible and you cannot create any reports.
TH LINK PC
The runtime license activates the complete software functionality.
There is no demo license for this product.
TH LINK PC can be started without having a valid license file available. You are able to modify language and measurement settings but you cannot start a measurement without a valid license.
dataCHECK Analyser IE
The dataCHECK Analyser license is a combination of two licenses (TH SCOPE and TH Link PC) and activates the fully software functionality.
There is no demo license for the product dataCHECK Analyser IE.
TH LINK PC can be started without having a valid license file available. You are able to modify language and measurement settings but you cannot start a measurement without a valid license.
The license on the USB dongle is correctly recognized in the Softing License Manager V4. However, demo license will be displayed on the TH SCOPE software web interface.
The TH SCOPE software is installed as a service. Windows starts the services first and then the user interfaces, so the USB dongle must be plugged in before the Windows startup.
1) Reboot your PC after the USB dongle is plugged in.
2) Stop the TH SCOPE service via Services.msc, connect the USB dongle and restart the TH SCOPE service.
The TH SCOPE software will then recognize the dongle license and mark it as a base license on the web interface.
TH LINK Ethernet
The version of TH LINK Ethernet can only be seen in TH SCOPE GUI on web browser.
TH LINK PC
The TH SCOPE itself does not have a password.
In the graphical user interface of the TH SCOPE software is always a TH LINK selected. In the login window you can use the appropriate TH LINK password.
The password of a hardware link is the serial number of the device.
The default password of the TH LINK PC is THLINK_Admin.
If TH LINK recognition or SNMP agent should be configured then the TH SCOPE configurator password is required. The TH SCOPE configurator password can only be entered in the configuration interface of the TH SCOPE. (http://localhost/THSCOPE/HTML5/Config)
To do this, select in the Windows Start menu All Programs Softing TH SCOPE and then click TH SCOPE configuration. Here you can enter in the login window the password and then click the "Login" button. The default password is THSCOPE_Admin.
In case of lost password the TH LINK device must be returned to Softing. For further information about this procedure please contact the sales department per e-mail: email@example.com
Softing will inform you about the costs and will reset the default password.
If you have not changed the password, then you can log in with the default password of the device, which can be found in the manual. In any case please try to login with the default password before you return the device to Softing.
enablement of the following ports:
There must be no firewall between the TH LINK and the PROFINET and/or EtherNet/IP devices.
If your network is protected by a second firewall in addition to the Windows firewall, make sure that the following settings are made to allow TH SCOPE services to communicate properly.
The following ports are used by TH SCOPE for internal communication only:
TH LINK Ethernet:
The log files will be saved directly in the device. The current log file name is THLink.log. If the size of the log file exceeds a certain value (normally 10 MB), the current file is copied to THLink_Bk.log.
Both files may be important.
The log file can be accessed in the web interface of the device. Open the trace file in a web browser as follows:
<IP address of the device>/debug/debugOutput.sh
TH LINK PC:
Location of the log files:
Where <InstallationPath> is the installation path of TH LINK on the PC
Default on a 64 bit system is:
C:\Program Files (x86)\Softing\TH LINK
TH LINK PROFIBUS:
Currently there is no trace files available.
The log files are located at:
The Acceptance Report functionality is contained in TH SCOPE Webserver. The Exception log of the Webserver is very important in case having any problems with the report.
Exception and Application log files are located at:
Where <InstallationPath> is the installation path of TH SCOPE on the PC
Default on a 64 bit system is:
C:\Program Files (x86)\Softing\TH SCOPE
Please click the link below to download the tool "TH LINK Search".
After successful installation start the utility. It automatically searches for all connected TH LINK devices in the network.
The following information will be determined:
Please note that network card and TH LINK device must be in the same subnet. Otherwise the TH LINK Search Tool doesn’t find the device!
In case the device will not be found then a Wireshark recording could further help to find out the IP Address of an Ethernet device.
Desired TH LINK will not be listed on the left side in the tree view of the TH SCOPE user interface. Accessing the device directly is possible using the IP address. The device can also be accessed successfully via “ping” from the command line.
Please make sure that the measurement on the TH LINK is started and the recognition has been completed with 100%.
Please enter the IP address of the device in the web browser and log in.
You can now start the measurement in the TH SCOPE tab by the "Start" button. After the measurement has started changes the button's label from "Start" to "Stop".
Now you can see in the status bar the current state of data initialization.
After the data initialization has been completed (100%), the TH LINK will be detected from the TH SCOPE Software.
The following error message appears when starting TH SCOPE: "There is no TH LINK accessible. Check the network connection and/or Try again later."
The connection to the TH LINK is possible if the IP address is entered directly in the browser.
To 2. Connect the PC to the network.
If broadcasts are blocked in your network for security reasons TH SCOPE can also run in manual mode. In this mode the IP addresses of the TH LINK devices can be entered directly:
Generally Ethernet frames are only transmitted within the same subnet. Therefore TH SCOPE can only access stations directly if they belong to the same subnet. To transmit frames to other subnets routers or gateways can be used.
A Router can substitute the IP address, which must be then configured there (e. g. NAT).
A gateway can only be specified in TH LINK when both IP address areas are set to “Manually” in the Network configuration tab. Otherwise TH LINK tries to find the gateway via the DHCP Server.
Only one gateway can be specified, which must fit one of the two IP address areas.
A firmware update to version 7.0.x.x is only possible from firmware version 126.96.36.199 or 188.8.131.52. If an update from earlier versions is planned, firmware version 184.108.40.206 has to be installed as an intermediate step first.
In case the device has a smaller firmware version as 220.127.116.11 then it is necessary to install the intermediate version 18.104.22.168 as the first step.
The order of the firmware updates is as follows:
22.214.171.124 or 126.96.36.199 -> 188.8.131.52 -> 184.108.40.206 or 220.127.116.11 -> 18.104.22.168 or 22.214.171.124
The intermediate versions of the firmware updates can be found here.
Attention: Firmware version 126.96.36.199 does not handle long host names correctly. Please don’t enter host names with more than 15 characters!
In the xEPI2 devices it is not possible to change the tag or the description in the inventory. The devices have the current firmware version 188.8.131.52. When saving, the message "Website could not be loaded ..." appears.
xEPI2 and also the successor product TH LINK PROFIBUS still needs Adobe Flash Player. (Other Softing TH LINK products do not need Adobe Flash Player anymore.)
Try to change the desired functionality using the latest TH SCOPE software instead of working directly with xEPI2. TH SCOPE works without Adobe Flash Player.
TH SCOPE has full functionality for 30 days without a license.
The TH LINK PROFIBUS / xEPI2 does not support automatic daylight saving time conversion.
If this browser message will be displayed then the device should be sent back to Softing for repair. Please use the product repair form on the web page:
The reported error message could be caused when you are using the firmware version 184.108.40.206 of the TH LINK PROFIBUS device and enter a long host name with more than 15 characters. The device cannot be accessed any longer. Entering the IP address of the device in the browser will cause the mentioned error message:
“XML data format is invalid. Please restart the session.”
The HTTP Error 503 message indicates that the Web server is temporarily unavailable. The issue is usually caused by the wrong IIS configuration (Microsoft Internet Information Services).
The required IIS configuration is automatically adjusted during the TH SCOPE installation if the user does not reject it. However, these settings cannot always be performed completely on the various operating systems (depending on the programs already installed).Therefore, check and if necessary correct the IIS settings described in the TH SCOPE Installation Manual (Chapter 6).
The HTTP Error 503 can also occur after a Windows Update. In this case please delete the temporary files manually under:
and restart the computer.
We have noticed that on some systems the Adobe 3D Capture Plugin prevents the correct start of the TH SCOPE.
As a workaround please uninstall the Adobe Plugin (or Adobe Acrobat 9 Pro).
Measurement cannot be started because the measurement button is grayed out.
- software is not licensed or
- network configuration issue
The dataCHECK Analyzer IE license package unlocks the full functionality of the software.
Without a valid license, no measurement can be performed.
Without a selection of a network adapter it is not possible to establish a network connection and start the TH SCOPE measurement. To be able to select the network adapter you must be logged in. The default password is THLINK_Admin.
Set the network adapter in the Settings -> THLINK window, through which the access to the network is to be established and save the setting.
After saving, you will be logged out automatically because the TH LINK and the TH SCOPE measurement both restart.
The quality index strongly depends on the type of field device and, in particular, on the segment length. In the majority of cases, a quality index of 4000 is very good. However, bus communication may still work with much less.
The topology scan uses a maximum baud rate of 500 kbit/s, even if you have set higher baud rate. As a result, devices that do not support automatic baud rate detection and have been set to a higher baud rate will not be found in the topology scan. Some (mainly older) devices will perform the automatic baud rate detection only once after startup. Therefore, you may have to temporarily disconnect them from the power supply.
A complete power supply kit is optionally available and can be ordered here.
This is a common issue depending on the PC/notebook type and operating system. It occurs particularly when using USB hubs with external power supply. Please connect the PB-T3 directly to the PC/notebook.
The PROFIBUS Tester measures the cable lengths to the respective slaves and then lists the slaves according to the cable lengths.
To perform a topology scan, the PROFIBUS Tester should be connected to the beginning of the physical segment. Consequently, when measuring the cable lengths from the center of a segment, the sequence of slaves determined by the PROFIBUS Tester will not correspond to the actual layout of the slaves.
In addition, a topology scan will only deliver reliable results, if the signal quality of all slaves on the bus is very good. If faults have already led to reflections on the bus, the reflections can impact accurate length measurement by the PROFIBUS Tester.
The measurement tolerance for the topology scan is +/- 1 meter.
The use of repeaters creates separate physical segments. For this reason, repeaters need to be disconnected from the bus (disconnect power supply or unplug the PROFIBUS cable) before running a topology scan. Each segment has to be measured separately.
My PROFIBUS Tester 4 has dropped down to the USB-socket and is malfunctioning. What next?
In spite of its weight PROFIBUS Tester 4 is quite robust and withstands mechanical stress to a considerable degree. Most of the testers being send to us for repair show a damaged USB-socket. We are already working on making the USB-socket more robust with respect to mechanical load. We kindly ask you for sending affected testers to us for repair if necessary. Please do not try to repair testers on your own. We recommend to screw tightly the device during testing. You may use a USB cable with angular B-plug which reduces the risk of damage to the USB-socket, should your PROFIBUS Tester 4 drop down accidentally.
In some situations a firmware update solves this issue.
Please download the latest version of the Diagnostics Suite V3.00 software inclusive firmware updates from our website. Install the software and update the firmware. After the firmware update was made, could be that the “IFLASH failed” message appears ones again. Please confirm it with the green button. Then the internal memory of the device will be formatted.
If the above procedure does not help then the device should be sent back for repair.
Please see our repair procedure and form on the website here:
The PROFIBUS Tester is maintenance-free and does not need to be calibrated. The PROFIBUS Tester does not measure physical values which can be compared to a reference standard.
A calibration takes place during the automatic production tests of the PROFIBUS Tester device before the delivery.
But we can offer a factory adjustment like it is done during production for extra charge. If you have interest on it, please contact our sales department: firstname.lastname@example.org
The PROFIBUS Tester 3 was discontinued in 2011. Its functionality is fully included in the PROFIBUS Tester 4 (BC-600-PB, begin of sales in 2010) and in the PROFIBUS Tester 5 (start of sales in 2014).
The last PC software for the PROFIBUS Tester 3 was the version 1.70.
Version 3.x of PROFIBUS Diagnostics Suite doesn’t support the PROFIBUS Tester 3 any more because the newly added features like cable test are absent on the PROFIBUS Tester 3.
The new Firmware 1.02.00.00 of the BC-700-PB (delivered with the PROFIBUS Diagnostics Suite V3.20) contains an oscilloscope function for stand-alone operation. The waveform of the PROFIBUS signal can be seen now on the display of the BC-700-PB without connected PC. Therefore an examination of the waveforms is possible in a simple manner. The signal A-B is shown with a maximum sampling rate of 384 MHz and 8192 sample points. It can be triggered on addresses, signal level and faulty telegrams. Sections can be shown per zoom and shift function. The presentation is intended as a "Live View", saving the contents on the PC is not possible. For this purpose the oscilloscope function in the PROFIBUS Diagnostics Suite should be used.
The oscilloscope function in stand-alone mode is enabled via an additional license, which is bound to the serial number of the device. Therefore the serial number must be stated when ordering the license. Customers who already own the PA option should also state the key of the PA license in order to ensure that the PA function is included in the new key.
The oscilloscope function in the PROFIBUS Diagnostics Suite is still available without any additional license.
Activated licenses are displayed in the BC-700-PB in menu Settings -> License.
Disabled functions or functions without a license will be grayed out or are not visible in the main menu in stand-alone mode.
When USB is connected you can view the license activation status in PC-software PROFIBUS Diagnose Suite (Help -> Hardware Info).
You can also see the installed licenses in the Softing License Manager V4. Select Softing Interface and then Interface Licenses tab. The connected device together with its serial number, installed options and license key is displayed.
You have to configure a new IP address. Please click the link below to download the Search & Configure tool. After successful installation, start the Search & Configure tool. It will automatically find all available BC-502-PB devices on your network.
Click the Configure button or double-click a device to display detailed configuration data of the selected device. The dialog entries vary depending on the type of device. You can modify the settings of a device by entering new values in the enabled input boxes in the middle column. To download these changes into the device, please enter the correct password and click the Submit button.
The PROFIBUS Monitor is delivered with the following default network configuration:
If more than one Monitor with default configuration settings is connected to the LAN network, only one Monitor will be able to successfully connect to the network (firmware May 2009). All other Monitor devices or PROFIBUS Ethernet gateways that have been started later will prematurely stop booting because the assigned IP address is already in use on the network.
There is a workaround to add multiple devices with the same IP address to the network and then modify their network configurations from a PC on the same network. This is done using the Softing Search and Configure tool. First, unplug the network cables of the devices concerned. Then force a restart of each device by temporarily disconnecting it from the power supply. The devices will now complete the startup successfully and can be reconnected to the network.
The "Softing Search and Configure" tool will now also detect devices with the same IP address and further identify them by other attributes, such as the serial number or MAC address. You can then select each Monitor and change its IP address by clicking the Configure button.
While several devices can be simultaneously connected to the bus, you must choose one device at a time to run a measurement on the active bus with the PROFIBUS Diagnostics Suite. The measurement cannot be started using several devices simultaneously.
To use this functionality, you have to have installed the latest version of the PROFIBUS Diagnostics Suite.
To save the recorded frames to a CSV file, click the Print icon in the Frames view. After you select the range, a preview window appears. Click on the Save icon in the toolbar at the top of the preview window and choose 'CSV'. You can then specify a name and location for the file.
Using BC-450-PB you can test the protocol simultaneously in DP- and PA-segment. Before running a trend test you have to decide in which segment (DP or PA) you want to run a trend test. Running a trend test in DP- and PA-segment simultaneously will lead to wrong test results. Please run a trend test in the corresponding segments separately.
The graphical user interface of PB-DIAG-Suite freezes when starting a trend test, if the live list does not contain any stations.
This is a reported issue in version 2.10 of PB-DIAG-Suite. To prevent this issue, please run a station scan prior to the trend test.
This bug is fixed in the version 2.11.
This is a reported issue in version 2.10 of PB-DIAG-Suite. To prevent this issue, please open the corresponding network status and press the corresponding display control “Clear Network Status”.
This bug is fixed in the version 2.11.
I am testing a network which runs a bitrate of 9,6kbit/s. When I am running the oscilloscope function sometimes error messages are displayed.
This is a reported issue in version 2.10 of PB-DIAG-Suite. The correction is scheduled for the next version.
When I am running the oscilloscope function, PB-DIAG-Suite displays in status bar strange processing lag values and/or bus status shows “red”, although the network is okay. Why this is the case?
Running simultaneously telegram recorder and oscilloscope function is principally possible. In version 2.10 of PB-DIAG-Suite this configuration will cause the above mentioned reported issue.
To prevent this issue, please decide in favour of one function and stop the other function (oscilloscope or telegram recording). The correction is scheduled for the next version.
I have simultaneously connected BC-4x0-PB and BC-600-PB to PB-DIAG-Suite via USB. What do I have to bear in mind?
In principle the operation is the same as compared to operation on a single device. In version 2.10 of PB-DIAG-Suite opening a channel via selection of the corresponding device in project explorer may cause an error message. To prevent this reported issue, please select the corresponding device on the start page. The correction is scheduled for the next version.
When starting a trend recording using PB-DIAG-Suite, the displayed logging period is not “Zero”. Why this is the case?
BC-600-PB contains an internal clock, which starts to run from “Zero” whenever a recording is started (frame recording, protocol analysis or trend recording). Typically a trend recording shall start at “Zero”. To prevent this reported issue we recommend to stop all other running functions such as the frame recorder. After that you can start trend recording.
When opening a frame recording (rpb-file) my mouse pointer continues to show an hour glass. Why this is the case?
Typically opening a telegram recording (rpb-file) in offline mode takes a couple of seconds. During this data input of information, the cursor changes its appearance (hour glass). Is the measurement device being plugged to a master device (test location) during the frame recording, the mouse pointer remains an hour glass and the processing lag value being displayed in status bar is growing continuously. This reported issue does not affect any available functions (such as search frames function) and will be fixed in the next update version.
Measurement can be performed in stand alone mode and all devices are detected properly.
However, the BC-700-PB is not detected if you try to do a measurement with the PROFIBUS Diagnose Suite software. In this case no measurement can be performed or the baud rate setting is "forgotten". Such a phenomenon has been observed with USB cable with a length of 2 meter or longer.
Please use a USB cable with a maximum length of 2 meters or shorter.
If you only see question marks rather than a meter value in the generated report then you should change to the Topology tab with connected BC-700-PB (very important) and assigned Network. Then click here the button “Copy to Global”.
Please configure the Trigger Condition in the Diagnostics Suite. The External (Trigger In) should be used as source for the trigger in the Oscilloscope View.
You need an external device (e.g. voltage measurement equipment) which triggers the PBT5 in case of e.g. voltage decrease. The reason is to find out whether the voltage decrease influences the PROFIBUS installation.
Please note, the external trigger input can only start the oscilloscope measurement but not the frame recording.
The external trigger output works exactly like the trigger in the Oscilloscope View, but with a small delay caused by the hardware driver.
So when the Oscilloscope View is active, trigger signals corresponding to the current oscilloscope trigger mode (address or voltage level) are generated at the trigger output pin.
In turn, the external trigger input may be used as source for the trigger in the Oscilloscope View.
Bus participants incl. bus addresses will be displayed during the signal quality measurement, but not the signal bars. Instead of that only the text “Timeout” appears.
If a quality index could not be determined within the specified time, the text "Time-Out" appears. You should check the station in this case or increase the "Measurement time-out" setting in the Signal Analysis Settings dialog box (menu Test -> Signal analysis setting).
At the bottom of the “Evaluation” tab, you can set a timeout for the signal analysis measurements. If a station does not exist or if a measurement cannot be properly completed for other reasons, the measurement is aborted for that station after the specified time and the next measurement is started. Because a signal analysis measurement always has to capture multiple frames of a station, you may need to increase the timeout setting when testing networks with many stations or low baud rates.
Maybe a configuration file is faulty, therefore the PROFIBUS Diagnostics Suite software can no longer be loaded.
Please navigate to the folder C:\ProgramData\Softing\PROFIBUS\Diag Suite\config
Check the files in that folder. If you find a file with a length of 0KB, delete it. If the file lengths are plausible, delete the file RecentData.cfg.
The missing configuration files will be created during the startup of the software.
After deleting the files the software should work properly again.
Please delete the snapshot file (last.npb) in the directory:
The file seems to be faulty.
You can choose between two different user modes for the workspace:
When you enable Standard mode, the expert functions for analyzing oscillograms and frames are not available. This mode gives new or less experienced users a clear, easy-to-use user interface with the standard display and control functions.
To change the user mode, open Settings from the menu bar and select User Mode.
Then the oscillogram and frame functions will be visible.
If you are asked for the configuration files and / or trace files in a support case, you will find them in the following folder:
This location may vary depending on the language and version of the Microsoft Windows operating system.
e.g. C:\ProgramData\Softing\PROFIBUS\Diag Suite\
Please archive the complete folder and send it to email@example.com. This folder contains the configuration files, log files, and much more.
If there are problems with a GSD file then please also send the following folder:
By default, only the exception logging is activated, which can be found in the program data directory at:
In most cases, this information is sufficient to investigate.
However, in some cases, extended log files (application log files) are required.
To enable application logging, you should also perform the following steps:
1. Open PDS
2. Press CTRL+SHIFT+T to open Tracer settings window
3. Select module “Main”
4. Check field “Enabled”
5. Change level to “DEBUG”
6. Rotation type can be kept in default “by date” and “Daily”
7. Click “Ok”
The application log files (AppStatus.trc) can be found at:
