Accumulator with Predefined Reset
Time
You can use the Accumulator component to add a source parameter to
the destination parameter in order, for example, to accumulate annual
precipitation in the system and to reset the calculation at a predefined
moment.
The destination parameter is stored in the static parameters to maintain
its value over reset or power shutdown. In addition, the destination
parameter can be reset according to a predefined schedule. The
Accumulator is always incremented when the source variable is
measured.
