IED parameters organizationThe organization of the parameters in a tree structure is visible in the plantstructure by expanding the setting tree. For each function, the parameters areorganized in basic and advanced groups. The advanced settings are used forapplication optimization. During a common write both the basic and advancedsettings are written to the IED.5.3 Connecting signals in SMTSMT is used to do cross references, see Figure 40:• between physical IO signals and function blocks.• for the GOOSE engineering.IEC08000173_2_en.vsdBIOBIOTRMFBsGOOSE InputsGOOSE FBs forbinary and analogdata, interlockingcommunicationand voltage controlIEC 61850SMAIFBsIEC08000173 V2 ENFigure 40: SMT: Operation principlesSection 5 1MRK 511 261-UEN -Protection and control engineering60 650 seriesEngineering Manual
