Each SRMEMORYQT function block hastwo outputs, where one is inverted. The memory setting controls if, after a powerinterruption, the flip-flop resets or returns to the state it had before the powerinterruption. The SET input has priority.SRMEMORYQT can propagate the quality, the value and the time stamps of thesignals via IEC 61850.Table 319:Truth table for SRMEMORYQT function blockSET RESET OUT NOUT0 0 LastvalueInvertedlast value0 1 0 11 0 1 01 1 1 0If Memory parameter is Enabled, the output result is stored in semi-retained memory.15.8.9.1 Function block GUID-8B04BA86-9685-4E73-9C04-3AE74752CDBF v1SRMEMORYQTSETRESETOUTNOUTIEC14000070-1-en.vsdIEC14000070 V1 EN-USFigure 177: SRMEMORYQT function block15.8.9.2 Signals GUID-4543C4C9-FAE2-4328-8DE2-4A5756A020E9 v1PID-3814-INPUTSIGNALS v5Table 320:SRMEMORYQT Input signalsName Type Default DescriptionSET BOOLEAN 0 Input signal to setRESET BOOLEAN 0 Input signal to resetSection 15 1MRK 511 408-UUS ALogic456 Phasor measurement unit RES670 2.2 ANSITechnical manual
