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.
Outputs are available for forward as well as reverse direction. The accumulated energy
values can be reset from the local HMI reset menu or with input signal RSTACC.
The maximum demand values for active and reactive power are calculated for the set
time tEnergy and the maximum value is stored in a register available over
communication and from outputs MAXPAFD, MAXPARD, MAXPRFD, MAXPRRD
for the active and reactive power forward and reverse direction until reset with input
signal RSTDMD or from the local HMI reset menu.
