6.5.4 ISDU
Minimum , Maximum , Average and Moving
Average outputs
are output in FLOAT32 format.
Before they are processed further and converted
from FLOAT32 to INT32 or UINT32, the output
signal must be checked to determine whether it
is larger than INT32_Max or UINT32_Max. If it is
larger, data type UINT64 or INT64 should be
used.

Statistics Data Configuration: Input Signal
All data types of process data objects can be used for
input configuration, with the exception of Boolean. The
respective Object IDs can be found in the respective
section on the function. Default value is 0,
this corresponds to no object .
Statistics Data Configuration: Time Period Unit
The time unit Time Period Unit can be set with one of the
values from Tab. 6-25 to calculate the minimum, maximum
and average. For example, to calculate minimum,
maximum and average for all 1-hour values, hours can be
selected as the unit for this subindex.
