Pocket tester ProfiTrace2 for PROFIBUS
The ProfiTrace PROFIBUS tester is a professional diagnostic tool that allows you to quickly and clearly detect errors in the PROFIBUS network – from faulty devices and cabling problems to electromagnetic interference.
You can use it for:
- diagnosing network outages and instability,
- preventive maintenance and signal quality monitoring,
- commissioning new installations,
- remote network analysis via a web interface (with ProfiHub B5+R or ComBricks).
Thanks to the intuitive ProfiTrace 2 software, you can get an overview, display measured voltages, addresses, and device errors, and create reports on the network status.
When to choose ProfiTrace Pro?
- If you want to use ProfiCaptain 2 for full simulation of a PROFIBUS MASTER station (e.g., you can read or write data to a connected PROFIBUS SLAVE station),
- If you need to measure PROFIBUS PA networks as well – a special connector for measuring them is included.
At FOXON, we use ProfiTrace ourselves for repairs and upgrades of PROFIBUS networks. We will be happy to teach you how to use it in our training course.

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?

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.
