6.8.6.1 Long-Term History
The long-term History function enables you to collect and store data in well-defined recording
intervals. The minimum and maximum value of each measured value within the recording inter-
val are stored as one 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, which
means that 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.

6.8.6.2 Export History
The export history function enables you to convert the long-term history data into a commonly
used document format, in order to use this data for your own calculations. The long-term history
can be exported as Microsoft
