15.1.2 Application
M13395-3 v6
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.
15.1.3 Setting guidelines
M13396-4 v9
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.
