Permanent tester ComBricks for PROFIBUS
The ProfiTrace PROFIBUS tester is a professional diagnostic tool that ComBricks is a unique tool for continuous monitoring and diagnostics of the PROFIBUS network, combining the functions of a repeater, bus analyzer, and OPC server in a single device. It allows technicians to monitor the status of the network from anywhere via a web interface—without having to be physically on site.
ComBricks continuously monitors signal quality, bus errors, communication interruptions, and interference – and sends an email or SNMP alarm in case of problems. It is the ideal solution for operations where a quick response to a fault is crucial.
6 advantages of ComBricks:
- Continuous online monitoring of the PROFIBUS bus (24/7)
- Web interface – access diagnostics from anywhere
- Modular system – up to 4 galvanically isolated segments
- Integrated oscilloscope and bar graph for monitoring signal quality
- Event history – recording of faults for analysis over time
- Option to transfer data via OPC or SNMP to higher-level systems
At FOXON, we not only sell ComBricks, we also use them ourselves in industrial installations – and we know how to configure them correctly and interpret the outputs. We will be happy to help you with selection and implementation. Read the case study to find out how ComBricks help take care of PROFIBUS at Hyundai.

PROFIBUS: 3 Sins and 10 Tips
The PROFIBUS industrial bus is highly tolerant and will forgive many faults. But if a critical fault occurs—or several small ones accumulate—you will definitely notice. That’s why this aging industrial network deserves attention. Even if faults on your network are still rare, they will gradually accumulate. What do our technicians recommend? What are their 10 tips for maintaining PROFIBUS?

The 3 Biggest Killers of the PROFINET Industrial Network
Our engineers perform diagnostics of industrial networks in hundreds of manufacturing companies. They travel across the country to find the causes of failures. We have asked them what problems they have most frequently diagnosed in customers' PROFINET networks recently. What have they told us?

Do you want to know why your industrial communication is dropping out? Know where the errors are on the bus and fix them quickly? How the PROFIBUS network works and how to upgrade it and make it more robust? Learn all this in a training session full of practical examples

ComBricks – permanent PROFIBUS Diagnostics via Ethernet
ComBricks is a unique solution that features user-friendly remote monitoring of PROFIBUS networks and thus provides you with an overview of their health. As part of prevention, ComBricks will alert you by email if any of these problems occur on your PROFIBUS network – repeats, lost stations, slaves requesting diagnostics, etc. All problems are saved to the internal memory and can then be reviewed via a web browser.
ComBricks doesn't require any special software installations on your PC. You only need to type your ComBricks' IP address into a web browser.

Pocket VS permanent PROFIBUS diagnostics
If you are in charge of several PROFIBUS networks and want to check their quality from time to time or troubleshoot problems that have already occurred in a particular PROFIBUS network, the ProfiTrace2 tester is a great tool for you. You connect to the PROFIBUS network and measure signal qualities, voltages, communication errors, presence of interference, etc. When the measurement is complete, you create a report and disconnect again. The tester can be left connected to the PROFIBUS network for longer periods of time, but requires a laptop to which it is connected via the USB port.
If you operate a PROFIBUS line that is critical to you and an unplanned failure of the PROFIBUS network is not desirable, then get permanent diagnostics via the ComBricks solution. You connect the device to the DIN rail, connect it to the PROFIBUS network, without the need to assign an address or change the PLC program. From the first moment of connection, the tester measures the PROFIBUS network 24/7 and provides comprehensive overviews of the network quality in clear tools. It alerts you in time to the first undesirable event such as lost stations, lost packets, corrupted messages, voltage drops, interference, etc.
