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.

19.2.2 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
400.
