15.2.7 Operation principle
The instantaneous output values of active and reactive power from the Measurements
(CVMMXN) function block are used and integrated over a selected time
tEnergy to
measure the integrated energy. The energy values (in MWh and MVarh) are available
as output signals and also as pulsed output which can be connected to a pulse counter.
