Plug-in, measure, result!
Complicated, incomprehensible tables and diagrams were yesterday! The PROFIBUS tester PB-QONE enables a modern maintenance: you get precise measuring results in seconds, which can be easily evaluated thanks to the graphic display based on the traffic-light principle. These and other useful features of the compact multifunctional device make it to the right hand of every maintenance engineer on the way to simple quality diagnosis in the PROFIBUS network.
Highlights PROFIBUS tester
- Ease of use, well-structured handling
- Simplified topology illustration with measuring site management
- Well-structured, editable report to process further in *.pdf or *.doc format
- Measuring results within seconds
- Simple evaluation through traffic-light function
Functions of PB-Q ONE
The PB-QONE detects and evaluate the state of the physical and logical transmission quality in the network reliably. The hardware is connected largely non-reactive to the PROFIBUS network by a supplied adapter.
With the PROFIBUS tester PB-QONE the transmission levels of the slaves in operation can be physically evaluated and displayed by a measurement bar chart as well taking into account the 7V-drivers of modern PROFIBUS devices. All measured and test results can be displayed and logged on the PC via a supplied software. The software is easy to use. A clear menu navigation allows you to switch between a diagnostic mode and an expert mode.

Evaluation of physical quality
The PROFIBUS tester is able to ascertain the amount of the voltage difference as well as the shapes of the signals during PROFIBUS telegram transmissions. The results are visualized in form of a bar diagram, showing a quality value for each analysed bus device.
Signal to noise ratio
The signal to noise ration indicates the shortest distance between a logic „0“ and the logic „1“. It shows how far the signal of a device is affected by external interferences or signal fluctuations. It helps to recognize sporadic physical errors.

Evaluation of communication quality
All bus devices are presented in form of a tree diagram, including address, module name and device symbol (access through GSD file). The colour highlighting (green, yellow, red) provides a quick condition evaluation of each device.
The telegram mode extends the range of analyses. A large number of filters and triggers is available to analyse the data traffic in terms events but also certain data content.
The integrated master simulator is designed to determine the actually wired bus topology and analyse the signal quality of the connected bus devices. The master simulator is used in the offline mode without SPC.
