Logical nodes (LNs) STMP and SVBR will be removed from IEC 61850-7-420 in favour to the identically named logical nodes in IEC 61850-7-4. However some data objects (DOs) will have a new name.
The mapping of the original DO names from IEC 61850-7-420 Ed.1 to the new ones of IEC 61850-7-4 Ed. 2.1 is as follows (only changed DO names are listed here):
STMP.TmpSt => Alm
STMP.TmpRteSt => RteAlm
STMP.MaxTmp => AlmSet.maxVal
STMP.MinTmp => AlmSet.minVal
STMP.MaxTmpRte => RteAlmSet.maxVal
SVBR.VbrAlmSpt => VbrAlmSet
SVBR.VbrTrSpt => VbrTripSet
SVBR.AxDspAlmSpt => AxDspAlmSet
SVBR.AxDspTrpSpt => AxDspTripSet
SVBR.VbrMag => Vbr
SVBR.VbrDir => has been removed
Proposal
Use LNs STMP and SVBR from IEC 61850-7-4 in future.
