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.

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,
