C.2.6 MMXU: ANALOG MEASURED VALUES
A limited number of measured analog values are available through the MMXU logical nodes.
Each MMXU logical node provides data from a C30 current and voltage source. There is one MMXU available for each con-
figurable source (programmed in the
SETTINGS  SYSTEM SETUP  SIGNAL SOURCES menu). MMXU1 provides data
from C30 source 1, and MMXU2 provides data from C30 source 2.
MMXU data is provided in two forms: instantaneous and deadband. The instantaneous values are updated every time a
read operation is performed by a client. The deadband values are calculated as described in IEC 61850 parts 7-1 and 7-3.
The selection of appropriate deadband settings for the C30 is described in chapter 5 of this manual.
IEC 61850 buffered and unbuffered reporting capability is available in all MMXU logical nodes. MMXUx logical nodes pro-
vide the following data for each source:
• MMXU1.MX.TotW: three-phase real power
• MMXU1.MX.TotVAr: three-phase reactive power
• MMXU1.MX.TotVA: three-phase apparent power
• MMXU1.MX.TotPF: three-phase power factor
• MMXU1.MX.Hz: frequency
• MMXU1.MX.PPV.phsAB: phase AB voltage magnitude and angle
• MMXU1.MX.PPV.phsBC: phase BC voltage magnitude and angle
• MMXU1.MX.PPV.phsCA: Phase CA voltage magnitude and angle
• MMXU1.MX.PhV.phsA: phase AG voltage magnitude and angle
• MMXU1.MX.PhV.phsB: phase BG voltage magnitude and angle
• MMXU1.MX.PhV.phsC: phase CG voltage magnitude and angle
• MMXU1.MX.A.phsA: phase A current magnitude and angle
• MMXU1.MX.A.phsB: phase B current magnitude and angle
• MMXU1.MX.A.phsC: phase C current magnitude and angle
• MMXU1.MX.A.neut: ground current magnitude and angle
• MMXU1.MX.W.phsA: phase A real power
• MMXU1.MX.W.phsB: phase B real power
• MMXU1.MX.W.phsC: phase C real power
• MMXU1.MX.VAr.phsA: phase A reactive power
• MMXU1.MX.VAr.phsB: phase B reactive power
• MMXU1.MX.VAr.phsC: phase C reactive power
• MMXU1.MX.VA.phsA: phase A apparent power
• MMXU1.MX.VA.phsB: phase B apparent power
• MMXU1.MX.VA.phsC: phase C apparent power
• MMXU1.MX.PF.phsA: phase A power factor
• MMXU1.MX.PF.phsB: phase B power factor
• MMXU1.MX.PF.phsC: phase C power factor
C.2.7 PROTECTION AND OTHER LOGICAL NODES
The following list describes the protection elements for all UR-series relays. The C30 relay will contain a subset of protec-
tion elements from this list.
• PDIF: bus differential, transformer instantaneous differential, transformer percent differential, current differential
