5.11.1 Long-Term History
The long-term history function enables you to collect and store data in well-defined recording
intervals. The minimum and maximum values of each measured value within the recording
interval are stored as 1 data set. Recording intervals can range from 4 hours up to 7 days.
Note
The data storage is limited to 100 data sets. New data sets will overwrite existing ones, i.e., data
set 101 overwrites data set 1.
Depending on the defined recording interval, the long-term history can range from 17 days (4 h
* 100 = 400 h = approx. 17 days) up to approx. 2 years.

1.
