CHAPTER 3: IEC 61850 COMMUNICATION MODEL IMPLEMENTATION CONFORMANCE STATEMENT (MICS)UR FAMILY – COMMUNICATIONS GUIDE 3-15133.5.4 System logical deviceThe Ctrl logical device contains logical nodes that model UR power system devices: breakers, switches, CTs, and VTs, andincluding interface to these such as AC inputs and contact I/O.The System logical device is available when the Advanced IEC 61850 option is purchased with the UR device.3.5.4.1 Logical node zero (LLN0)LLN0 is instantiated in all UR family devices implementing the System logical device.Table 3-169: LLN0 data objects and attributesunits.SIUnit ENUMERATED 4 Runits.multiplier ENUMERATED 0 RLNName: LLN0 LDevice inst: System UR element: Nameplate information for the logical nodesdata obj. data attribute Type FC UR Name Description R/W/CBeh ENS This logical device’s behaviour 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 RsetSrcRef ObjectReference SP For communications, mapped toMaster ldName if not empty,otherwise to the concatenationof the IED name and “Master”.For SCL, mapped to theconcatenation of the IED nameand “Master”.reference to the data attribute to input RMltLev SPG Instantiated only in the Master logicaldeviceRsetVal BOOLEAN SP RΣDataSet##>DATA-SET RDSMemberRef[η] ObjectReference DataSet Member η R/CLNName: UFlt0RFLO1 LDevice inst: ctrl UR element: USER PROGRAMMABLE FAULT REPORT actual values and cleardata obj. data attribute Type FC UR Name Description R/W/C
