6.3 Event list
The event list shows the recorded fault entries. The table illustrates when and how often certain telegram
errors occur. The events are shown based on their address and can be grouped with a sorting function.
6.4 Comparison
Stable physical conditions are the foundation of fault-free Profibus communication. When commissioning a
new system or modifying an existing system, we therefore recommend performing an evaluation of the
quality values to document the status quo and as a reference for future measurements. In order to detect
changes in the physical condition early on, and for before/after comparisons in the event of a fault, the

has a compare function. In a first step, load the stored measurement file and select the relevant
measuring point. Next, perform a current measurement at this point. Using the "Compare with" drop-down
menu, load the values from the initial measurement for comparison. The two measurement series are
juxtaposed, and potential deviations for each address become detectable.
