The PB-Q ONE is a mobile PROFIBUS diagnostic tool for the complete evaluation of PROFIBUS communication quality including PROFIBUS cables, PROFIBUS signals, and the communication between PROFIBUS PLCs and the PROFIBUS network devices. Its ease of use and clear and automated evaluation of measuring results allow to reliably evaluate the state of the physical and logical transmission quality in the network. In addition, the PB-Q ONE offers a powerful topology function.

The whole PROFIBUS troubleshooting process happens in seconds with precise measuring results which can easily be evaluated with a modern traffic light principal display. The PROFIBUS diagnostic results can be printed and shared or kept as reference points for future PROFIBUS troubleshooting's.

With the PB-Q ONE you will have an affordable and multi-functional device for acceptance, commissioning, diagnostics, maintenance, service, and troubleshooting needs for PROFIBUS DP and PROFIBUS PA networks.

The PB-Q ONE is the best-in-class and most affordable PROFIBUS tester for PROFIBUS networks - PLUG-IN, MEASURE, RESULT!

Measuring Results

In the overview, all PROFIBUS devices are displayed in the form of a device matrix including address and detailed information. The coloring of each devices (green, yellow, red) allows to immediately evaluate the state of each device. Additionally, the results of the PROFIBUS physics and bus communication evaluation are clearly displayed.

Quality Values

PROFIBUS is based on a voltage difference signal which transfers the logical telegram content to the wires A and B. The level of the voltage difference as well as the shape of these signals are indicators of the physical transmission quality respectively the signal quality. As a result a bar chart diagram with a quality value for each device in the network is displayed.

Telegram Mode

Further analysis possibilities are available in the telegram mode. Through a number of filter and trigger options the data traffic can be evaluated based on events or defined data content.

The M12 Y measuring adapter is used to connect the PROFIBUS tester PB-QONE.


The foundation of a long-term stable PROFIBUS network includes training of the maintenance personnel and having the right tools available to identify error causes fast and reliable. The cost for both pay for itself after a short period of time due to reduced unnecessary machine downtime and by avoiding the unnecessary replacement of devices which are still in perfect order.


Frequently Asked Questions

Which PROFIBUS variants does PB-Q ONE support?
PB-Q ONE is a PROFIBUS DP (RS-485) tester. With the optional PROFIBUS PA adapter, it can evaluate PA segments used in process automation.
Can I test a live network without stopping production?
Yes. PB-Q ONE enables non-intrusive PROFIBUS diagnostics on running lines, so you can validate signal quality and locate faults while the plant stays online. Always follow site safety procedures and connect at approved test points.
What types of issues can it detect?
Common PROFIBUS network faults include cable defects (opens, shorts, shield/ground), reflections/impedance mismatches, incorrect termination, EMI/industrial noise, device drops/retries, and timing problems that cause communication errors.
Can I export test results and create acceptance/certification reports?
Yes. PB-Q ONE generates acceptance reports for commissioning and maintenance. You can export data and logs (e.g., PDF/CSV) to share with OEMs/integrators or to attach to CMMS/maintenance records for compliance and documentation.
Does PB-Q ONE perform topology mapping and device discovery?
Yes. PB-Q ONE provides network topology scans and device identification to document installations, map physical/logical layouts, and plan corrective actions—especially helpful in complex or legacy PROFIBUS networks.
How is PB-Q ONE different from multimeters or oscilloscopes?
PB-Q ONE is a protocol-aware PROFIBUS analyzer. It correlates physical-layer quality with data-link communication behavior and produces ready-to-share acceptance documentation—saving time versus manual captures with general-purpose instruments.
Does it work with Siemens, Softing, or other third-party systems?
Yes. PB-Q ONE analyzes the PROFIBUS physical/communication layer independent of PLC/drive brands and is used in mixed-vendor environments (e.g., Siemens, ABB, Rockwell via gateways, etc.).
What if I need continuous or permanent PROFIBUS network monitoring?
For ongoing condition monitoring and early fault detection, use the PROFIBUS-INspektor® NT , designed for permanent PROFIBUS monitoring and predictive maintenance.
Who do I contact for demos or RFQs?
