CHAPTER 3: IEC 61850 COMMUNICATION MODEL IMPLEMENTATION CONFORMANCE STATEMENT (MICS)UR FAMILY – COMMUNICATIONS GUIDE 3-19333.5.6 General (Gen) logical deviceThe Ctrl logical device contains logical nodes that model UR FlexLogic, Virtual Outputs, non-volatile latches, FlexElements,and recording (for example, oscillography) functions.The Ctrl logical device is available when the Advanced IEC 61850 option is purchased with the UR device.3.5.6.1 Logical node zero (LLN0)LLN0 is instantiated in all UR family devices implementing the Gen logical device.Table 3-203: LLN0 data objectsphsθHar(n).units Unit CF RphsθHar(n).units.SIUnitENUMERATED 1, the code for dimensionless(percentage)RphsθHar(n).units.multiplierENUMERATED -2 RphsθHar(n).db INT32U CF HThdMHAI#.HPhV.phsθHar(n).db R/W/CphsθHar(n).zeroDb INT32U CF 0 RnumHar INT16U CF 25 RnumCyc INT16U CF 1 RevalTm INT16U CF (1/ NOMINAL FREQUENCY) *1000Rfrequency FLOAT32 CF NOMINAL FREQUENCY RrmsCyc INT16U CF 1 RLNName: LLN0 LDevice inst: Gen UR element: Nameplate information for the logical nodesdata obj. data attribute Type FC UR Name Description R/W/CBeh ENS This logical device’s behavior RstVal ENUMERATED ST RstVal ENUMERATED ST LLN0.Beh.stVal of the Masterlogical deviceRHealth ENS Only instantiated in the Master logicaldeviceRstVal ENUMERATED ST LPHD1.PhyHealth.stVal ROn SPS Only instantiated in the Master logicaldeviceRstVal BOOLEAN ST ROff SPS Only instantiated in the Master logicaldeviceRstVal BOOLEAN ST RZero MV Only instantiated in the Master logicaldeviceRmag AnalogueValue MX Rmag.f FLOAT32 0.0 RMod ENC Only instantiated in the Master logicaldeviceR/CtrlctlVal ENUMERATED RstVal ENUMERATED ST RctlModel CtlModels CF LLN0.Mod.ctlModel 2, the code for SBO control with normalsecurity according to IEC 61850-7-2.R/CsboTimeout INT32U CF 30000 RsboClass SboClasses CF 0 (operate-once) RoperTimeout INT32U CF 0 RGrRef ORG Reference to root logical device RLNName: HThdMHAI# LDevice inst: Meter UR element: Harmonics and THD meteringdata obj. data attribute Type FC UR Name Description R/W/C
