Thepulses are captured by the binary input module (BIM), and read by the PCFCNT function. Thenumber of pulses in the counter is then reported via the station bus to the substation automationsystem or read via the station monitoring system as a service value. When using IEC 61850–8–1, ascaled service value is available over the station bus.The normal use for this function is the counting of energy pulses from external energy meters. Anoptional number of inputs from an arbitrary input module in IED can be used for this purpose witha frequency of up to 40 Hz. The pulse-counter logic PCFCNT can also be used as a general purposecounter.17.1.3 Setting guidelines M13396-4 v9Parameters that can be set individually for each pulse counter from PCM600:•Operation:Disabled/Enabled•tReporting:0-3600s•EventMask:NoEvents/ReportEventsConfiguration 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, thecounter suppresses pulses with a pulse length less than 1 ms. The input oscillation blockingfrequency is preset to 40 Hz meaning that the counter detects the input to oscillate if the inputfrequency is greater than 40 Hz. Oscillation suppression is released at 30 Hz. Block/release values1MRK 511 358-UUS A Section 17Metering445Application manual
