18.4.2 Setting guidelines M15259-3 v4The setting ActiveSetGrp, is used to select which parameter group to be active. Theactive group can also be selected with configured input to the function blockSETGRPS.The length of the pulse, sent out by the output signal SETCHGD when an activegroup has changed, is set with the parameter t.The parameter MAXSETGR defines the maximum number of setting groups in useto switch between. Only the selected number of setting groups will be available inthe Parameter Setting tool (PST) for activation with the ActiveGroup functionblock.18.5 Rated system frequency PRIMVAL IP15064-1 v218.5.1 IdentificationGUID-B8B3535D-227B-4151-9E98-BEB85F4D54DE v1Function description IEC 61850identificationIEC 60617identificationANSI/IEEE C37.2device numberPrimary system values PRIMVAL - -18.5.2 Application M15288-3 v6The rated system frequency and phase rotation direction are set under Main menu/Configuration/ Power system/ Primary Values in the local HMI and PCM600parameter setting tree.18.5.3 Setting guidelines M15292-3 v2Set the system rated frequency.
