Function description
Function for energy calculation and
demand handling
17.2.2 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 98.

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 Display Editor tool (GDE) with a measuring value
which is selected to the active and reactive component as preferred. Also all Accumulated Active
Forward, Active Reverse, Reactive Forward and Reactive Reverse energy values can be presented.
Maximum demand values are presented in MWh or MVArh in the same way.

The setting is common for all input channels on BIM, that is, if limit changes are
made for inputs not connected to the pulse counter, the setting also influences the
inputs on the same board used for pulse counting.
