1 Introduction
1.1 General
The PB-Q
ONE
is an easy to use, powerful measuring device for comprehensive inspection of PROFIBUS
master systems. It offers separate testing of the physical condition of the bus (signal quality) and the
telegram traffic. The device can be used for acceptance measurement on new systems for inclusion in the
acceptance report, as well as for targeted troubleshooting of existing systems.
Its integrated master simulator enables testing of the communication quality without a need for the PLC to
be operational. This enables pre-inspection of complete systems and their parts during the commissioning
stage, with the goal of providing stable bus systems for trouble-free production in the long term.
The device is connected to a PC or notebook via a USB interface, which also provides the power supply. It
is controlled with the “Indu-Sol Suite” software.
1.2 Functional overview
The PB-Q
ONE
is designed to assist you with inspection, troubleshooting, and the isolation of root causes.
To this end, it offers the following functions:

Feedback-free bus coupling at suitable existing measuring points during running operation

Automatic detection of the baud rate

Automatic identification of all devices on a bus system (LiveList)

Device and measuring-point-based display of signal ratios:
o
General quality value
o
Signal to noise ratio and slope gradient
o
Oscilloscope display with selection options for detailed evaluation

Long-term monitoring of all devices (continuous measurement) with minimum, maximum, and average
quality values

Editable measuring point and segment management

Wear inspection by comparing current readings with stored measurements

Integrated master simulator for inspection of system without a master (commissioning phase)

Real-time monitoring of the entire data traffic and checking for telegram errors, with entries into the
event list

In-depth telegram analysis with option for variable trigger setting

Easy documentation of measurements in the form of an acceptance report and topology plan
