4.5.6 Topology display
The total line length, the determined line lengths between the stations and their topological order, as well as
the positions of the measuring points, are displayed here (circular icons with the number of the measuring
point index). The length specifications in meters always specify the distances between two stations.
If the DMF information is available for a station, the device designation is also displayed.
4.6 "Quality Levels All Stations" view
4.6.1 How to use
The "Quality Levels All Stations" view provides an overview of the signal conditions of all stations. The mea-
sured quality level is displayed clearly in a bar diagram for each station. Any minimum and maximum values
are also marked graphically so that any variations can be noticed easily. The following additional information
is displayed:
Glitch, edge and level error counters
Minimum and maximum values of the quality level together with a time stamp
The measurement can be carried out both as a single measurement (each station is measured only once)
and as a continuous measurement. Fig. 8 shows a screenshot of this view.
4.6.2 Setting and measuring
The requirements for this measurement are:
The PBT must be connected both to a PC and to the PROFIBUS plant (bus status LED = green/yellow)
The correct baud rate must be selected.
The master simulator must be activated if necessary (only required when performing a measurement on
an idle plant - bus status LED = yellow/red, differential voltage > 0.1 V)
The correct measuring point must be selected.
At least one station must exist in the station list and must be marked as "to be measured".
After switching to the "Quality Levels All Stations" view ("View" menu or toolbar), you can control the mea-
surement using the following icons or menu functions ("Measure" menu):
