The configuration of the inputs and outputs of the pulse counter-logic PCFCNT function
block is made with PCM600.
On the Binary Input Module, 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. That means that the counter finds the input
oscillating if the input frequency is greater than 40 Hz. The oscillation suppression is
released at 30 Hz. The values for blocking/release of the oscillation can be changed in the
local HMI and PCM600 under Main menu/Configurations/I/O modules.
The setting is common for all input channels on a Binary Input Module,
that is, if changes of the limits 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 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 182.
