can we use _dp_fct to perform a statistical calculation over a defined period?
for example I want to perform the calculation on an interval that can be modified programmatically
I'm looking for the best method to calculate an OEE
Thank you for your opinions

Re: _dp_fct / how to perform stat calculation over defined period
Most statistical calculation can be done with a dyn function, so it might be doable without _dp_fct.
But not sure which calculations you need, so it is hard to say if this is a valid approach.

Re: _dp_fct / how to perform stat calculation over defined period
A _dp_fct config has 2 possibilities:
-- Datapoint function: Triggered by a value change of the referenced datapoint elements
-- Statisitcal datapoint function: Calculation in a defined interval
If you want to do a calculation with different time intervals you have to write your own function for it which reads data from the database and does the calculation.
