3.16.2.1 Application
Energy calculation and demand handling function ETPMMTR is intended for statistics
of the forward and reverse active and reactive energy. It has a high accuracy basically
given by the measurements function (CVMMXN). This function has a site calibration
possibility to further increase the total accuracy.
The function is connected to the instantaneous outputs of (CVMMXN) as shown in
figure 311.

The energy values can be read through communication in MWh and MVarh in
monitoring tool of PCM600 and/or alternatively the values can be presented on the
local HMI. The local HMI graphical display is configured with PCM600 Graphical
