LTHist
The LTHist function is part of the Trigger class.
It allows you to perform a simple 'less than' comparison that includes hysteresis, to prevent your condition function from flickering on and off when values are near thresholds.
Parameters
| Name | Description |
|---|---|
| value | The value you want to compare |
| threshold | The threshold you want to compare against |
| span | The amount of hysteresis |
Example
lambda o: o.LTHist(o.Value(),50,10)
In this example condition function, the value is being compared against '50. When the value goes under 50, the output changes to True.
It will continue to output True until the value rises to 60 (the threshold plus the span)
Return
The function returns True or False
