Compact PROFIBUS tester for uncomplicated diagnostics and measurement in PROFIBUS networks

Evaluation of the physical and logical communication quality of your PROFIBUS system

The PB-Q^ONE is a tool for the complete evaluation of PROFIBUS communication quality. The hardware is connected to the PROFIBUS system by a supplied adapter.

Its simple, intuitive operability and the clear evaluation of the measurement results enable the state of the physical and logical transmission quality in the network to be reliably evaluated within seconds.

In addition, the PB-Q^ONE offers fully automatic and completely feedback-free topology determination under running production conditions. As a result, the PB-Q^ONE records the actual connection of all network devices and even identifies repeaters, measuring points and the cable lengths between the devices. The graphic display shows measurement locations and segment structures at a glance.

This makes the PB-Q^ONE ideally suited for every thinkable application such as certification and commissioning, maintenance and service as well as troubleshooting.

Display of quality values (PROFIBUS measurement with PB-Q ONE)

Simple display of quality values

The levels of the bars (in green, yellow or red) infer a measure of the physical transmission quality which includes an evaluation of the differential voltage, rising edges and the transient response. As a result all capacitive, inductive and resistive effects become visible.

Evaluation of physical quality

Signal 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 ratio 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

Device details

All bus devices are presented in form of a tree diagram, including address, module name and device symbol. The colour highlighting (green, yellow, red) provides a quick condition evaluation of each device.

Telegram mode

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.

Master simulator

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.
