Configuration of inputs and outputs of PCFCNT is made via PCM600.
On the Binary input module (BIM), the debounce filter default time is set to 1 ms, that
is, the counter suppresses pulses with a pulse length less than 1 ms. The input
oscillation blocking frequency is preset to 40 Hz meaning that the counter detects the
input to oscillate if the input frequency is greater than 40 Hz. Oscillation suppression is
released at 30 Hz. Block/release values for oscillation can be changed on the local HMI
and PCM600 under Main menu/Configuration/I/O modules.
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.

Function description
Function for energy calculation and
demand handling
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 413.
