Statistical Calculations
The statistical calculations also have a selection of quick calculation
sets. These quick calculation sets include:
- Quick statistic (avg, min, max),
- Quick statistic (sum), and
- Quick statistic (dev).
The different statistical functions are described in Table 9 on page 83 .
There are also timestamps available for the minimum and maximum
spans of the statistic calculation. The optional timestamps are listed in
Table 10 on page 83 .
Table 9 Available Statistical Functions
Name Description
Avg Average value over given calculation period
Min Minimum value over given calculation period
Max Maximum value over given calculation period
Sum Sum over given calculation period
Dev Standard deviation over given calculation period
Table 10 Timestamps for Statistical Calculations

MIN_H Hour when the minimum was detected
MIN_M Minute when the minimum was detected
MIN_S Second when the minimum was detected
MAX_H Hour when the maximum was detected
MAX_M Minute when the maximum was detected
MAX_S Second when the maximum was detected
NOTE The use of timestamps increases the use of the RAM memory,
therefore timestamps should only be used when absolutely necessary.
