parameters are available in the IED. Any of them can be activated through the differentprogrammable binary inputs by means of external or internal control signals.A function block, SETGRPS, defines how many setting groups are used. Setting is donewith parameter MAXSETGR and shall be set to the required value for each IED. Only thenumber of setting groups set will be available in the Parameter Setting tool for activationwith the ActiveGroup function block.18.7.2 Setting guidelinesThe setting ActiveSetGrp, is used to select which parameter group to be active. The activegroup can also be selected with configured input to the function block SETGRPS.The length of the pulse, sent out by the output signal GRP_CHGD when an active grouphas changed, is set with the parameter t.The parameter MAXSETGR defines the maximum number of setting groups in use toswitch between. Only the selected number of setting groups will be available in theParameter Setting tool (PST) for activation with the ActiveGroup function block.18.8 Rated system frequency PRIMVAL18.8.1 IdentificationFunction description IEC 61850identificationIEC 60617identificationANSI/IEEE C37.2device numberPrimary system values PRIMVAL - -18.8.2 ApplicationThe 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.18.8.3 Setting guidelinesSet the system rated frequency.
