Remarks
The average is calculated according to the number of stored samples, that can be less that N when the block is enabled. In LD language, the input rung is the RUN command. The output rung keeps the state of the input rung.
The "N" input is take into account only when the RUN input is FALSE. So the "RUN" needs to be reset after a change.
