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.
