8.3.3 Trend function
Trend logging is used for detecting rare or sporadic faults over a prolonged
period of time. The function monitors both the bus physics and critical events
in the bus communication. The PROFIBUS Tester 4 can automatically test the
bus in stand-alone mode from within the control cabinet for up to 41 days. The
test data is stored in the tool. It can subsequently be imported by the
PROFIBUS Diagnostics Suite software application.
Before you start the function, choose a test interval. When you select “Auto”
the tool automatically determines the optimum interval. The Trend Test runs
until manually stopped with the “x” key.

The test is aborted automatically when the power supply is interrupted (all data
logged so far is retained in memory) or when the maximum logging time of 999
hours and 59 minutes is reached.
