The SMAI function blocks for the 650 series of products are possible to setfor two cycle times either 5 or 20ms. The function blocks connected to aSMAI function block shall always have the same cycle time as the SMAIblock.15.9.2 IdentificationFunction description IEC 61850identificationIEC 60617identificationANSI/IEEE C37.2device numberSignal matrix for analog inputs SMAI_20_x - -15.9.3 Function blockANSI09000137-1-en.vsdSMAI_20_1BLOCKDFTSPFCREVROT^GRP1_A^GRP1_B^GRP1_C^GRP1_NSPFCOUTAI3PAI1AI2AI3AI4AINANSI09000137 V1 ENFigure 272: SMAI_20_1 function blockSMAI_20_2BLOCKREVROT^GRP2_A^GRP2_B^GRP2_C^GRP2_NAI3PAI1AI2AI3AI4AINANSI09000138-1-en.vsdANSI09000138 V1 ENFigure 273: SMAI_20_2 to SMAI_20_12 function blockNote that input and output signals on SMAI_20_2 to SMAI_20_12 are thesame except for input signals GRPx_A to GRPx_N where x is equal toinstance number (2 to 12).1MRK 511 287-UUS A Section 15Basic IED functions609Technical manual
