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 interval tEnergy. The maximum values are updated every minute and 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.
