Rise and Fall
The Rise and Fall processor detects when a value crosses upward through a lower threshold or downward through an upper threshold, and reports the timestamp and duration of each crossing.
Why use Rise and Fall
Use this processor to measure how long a value takes to transition past a threshold, for example, timing how long a tank takes to start filling once it drains below a low-level mark, or how long a motor takes to cool below an operating-temperature threshold.
How it works
Set a Lower and an Upper threshold. When the current value crosses upward through Lower, the processor reports that as a rise, along with its timestamp and rise time, in seconds. When the current value crosses downward through Upper, the processor reports that as a fall, along with its timestamp and fall time, in seconds.
Use Kpi to choose whether the processor tracks rises, falls, or both. Use Tolerance to ignore fluctuations too small to count as a genuine rise or fall.
Parameters
Parameter | Details |
|---|---|
Kpi | Whether to calculate rise, fall, or both, for the given data. |
Upper | The value above which the data is considered to be rising or falling. |
Lower | The value below which the data is considered to be rising or falling. |
Tolerance | Changes in the data below this amount are ignored when calculating rise and fall. |
Pass Through Value | Determines whether the processor's output is the rise or fall event data or the original unchanged input value. |
