energy values are available as output signals and also as pulse outputs. Integration ofenergy values can be controlled by inputs (STARTACC and STOPACC) and EnaAccsetting and it can be reset to initial values with RSTACC input.The maximum demand for active and reactive powers are calculated for the set timeinterval tEnergy and these values are updated every minute through output channels.The active and reactive maximum power demand values are calculated for bothforward and reverse direction and these values can be reset with RSTDMD input.17.2.3 Function blockETPMMTRP*Q*STARTACCSTOPACCRSTACCRSTDMDACCINPRGEAFPULSEEARPULSEERFPULSEERRPULSEEAFALMEARALMERFALMERRALMEAFACCEARACCERFACCERRACCMAXPAFDMAXPARDMAXPRFDMAXPRRDIEC14000019-1-en.vsdIEC14000019 V1 ENFigure 455: ETPMMTR function block17.2.4 SignalsTable 715:ETPMMTR Input signalsName Type Default DescriptionP REAL 0 Measured active powerQ REAL 0 Measured reactive powerSTARTACC BOOLEAN 0 Start to accumulate energy valuesSTOPACC BOOLEAN 0 Stop to accumulate energy values.RSTACC BOOLEAN 0 Reset of accumulated enery readingRSTDMD BOOLEAN 0 Reset of maximum demand readingTable 716:ETPMMTR Output signalsName Type DescriptionACCINPRG BOOLEAN Accumulation of energy values in progressEAFPULSE BOOLEAN Accumulated forward active energy pulseEARPULSE BOOLEAN Accumulated reverse active energy pulseTable continues on next pageSection 17 1MRK502052-UEN BMetering986Technical manual
