Function description
Pulse-counter logic
16.1.2
Application
Pulse-counter logic (PCFCNT) function counts externally generated binary pulses, for instance
pulses coming from an external energy meter, for calculation of energy consumption values. The
pulses are captured by the binary input module (BIM), and read by the PCFCNT function. The
number of pulses in the counter is then reported via the station bus to the substation automation
system or read via the station monitoring system as a service value. When using IEC 61850–8–1, a
scaled service value is available over the station bus.
The normal use for this function is the counting of energy pulses from external energy meters. An
optional number of inputs from an arbitrary input module in IED can be used for this purpose with a
frequency of up to 40 Hz. The pulse-counter logic PCFCNT can also be used as a general purpose
counter.
16.1.3
Setting guidelines
Parameters that can be set individually for each pulse counter from PCM600:
•
Operation: Off/On
•
tReporting: 0-3600s
•
EventMask: NoEvents/ReportEvents
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.
