The data reduction Minimum
is used for determining the
minimum of a variable within an interval. Possible settings
are:

Parameters |
Description |
---|---|
Time-limited |
Calculation of average over time. |
Event triggered |
Average is calculated when an event variable changes. |
Time |
Entry of the numeric value for the corresponding time (real-time synchronous, i.e. entry 15 means 15, 30, 45, 0 etc.). |
Seconds, minutes, hours, days |
Selection of the time interval. |
Offset |
Delay for start and end of the average calculation. |

result
Parameters |
Description |
---|---|
At the end of the interval |
The value is only provided at the end of the interval; until then, only the previous value is available. |
continuous |
The value is updated during each scan of the source variable. |
Initialization
at the start of the interval
Parameters |
Description |
---|---|
With existing value |
Value is based on previous value. |
with new value |
Value must be re-calculated. |
Info |
The synchronization time is determined based on the time interval. Example: If you configure the time interval to be 15 minutes, the calculation will be performed every 15 minutes, starting with the full hour. |
