14.2.7 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
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
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.
