Every sample occasion, there is a new current value from the motor. Then a number of calculations
have to be updated.

Accumulated Service Index, SI

(Ah)

The estimation is that the motor current has been fixed to this value the whole period since the last
sample. This SI value must be calculated unique for every component on the conveyor. This means
there are one value for SI connected to the chain and one for the slide rail, both using the formula
below.
