Event counter with limit supervison L4UFCNTGUID-13157EAB-1686-4D2E-85DF-EC89768F3572 v5The 30 limit counter L4UFCNT provides a settable counterwith four independent limits where the number of positiveand/or negative flanks on the input signal are counted againstthe setting values for limits. The output for each limit isactivated when the counted value reaches that limit.Overflow indication is included for each up-counter.Running hour-meter (TEILGAPC) GUID-464FB24F-B367-446C-963A-A14841943B87 v1The Running hour-meter (TEILGAPC) function is a functionthat accumulates the elapsed time when a given binary signalhas been high.The main features of TEILGAPC are:• Applicable to very long time accumulation (≤ 99999.9hours)• Supervision of limit transgression conditions and rollover/overflow• Possibility to define a warning and alarm with theresolution of 0.1 hours• Retain any saved accumulation value at a restart• Possibilities for blocking and reset• Possibility for manual addition of accumulated time• Reporting of the accumulated time10. MeteringPulse-counter logic PCFCNT M13394-3 v7Pulse-counter logic (PCFCNT) function counts externallygenerated binary pulses, for instance pulses coming from anexternal energy meter, for calculation of energy consumptionvalues. The pulses are captured by the binary input moduleand then read by the PCFCNT function. A scaled servicevalue is available over the station bus. The special Binaryinput module with enhanced pulse counting capabilities mustbe ordered to achieve this functionality.Function for energy calculation and demand handling(ETPMMTR) GUID-6898E29B-DA70-421C-837C-1BBED8C63A7A v2Measurements function block (CVMMXN) can be used tomeasure active as well as reactive power values. Function forenergy calculation and demand handling (ETPMMTR) usesmeasured active and reactive power as input and calculatesthe accumulated active and reactive energy pulses, in forwardand reverse direction. Energy values can be read orgenerated as pulses. Maximum demand power values arealso calculated by the function. This function includes zeropoint clamping to remove noise from the input signal. Asoutput of this function: periodic energy calculations,integration of energy values, calculation of energy pulses,alarm signals for limit violation of energy values and maximumpower demand, can be found.The values of active and reactive energies are calculated fromthe input power values by integrating them over a selectedtimetEnergy. The integration of active and reactive energyvalues will happen in both forward and reverse directions.These energy values are available as output signals and alsoas pulse outputs. Integration of energy values can becontrolled by inputs (STARTACC and STOPACC) andEnaAccsetting and it can be reset to initial values with RSTACCinput.The maximum demand for active and reactive powers arecalculated for the set time intervaltEnergy and these valuesare updated every minute through output channels. Theactive and reactive maximum power demand values arecalculated for both forward and reverse direction and thesevalues can be reset with RSTDMD input.11.
