When usingIEC 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 thispurpose with a frequency of up to 40 Hz. The pulse-counter logic PCFCNT can also be used as ageneral purpose counter.17.1.3 Setting guidelines M13396-4 v9Parameters that can be set individually for each pulse counter from PCM600:•Operation:Off/On•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 theinput 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.1MRK 511 358-UEN A Section 17Metering401Application manual
