Mmxu: Analog Measured Values; Protection And Other Logical Nodes - GE G60 Instruction Manual

C.2 SERVER DATA ORGANIZATION
A limited number of measured analog values are available through the MMXU logical nodes.
Each MMXU logical node provides data from a G60 current and voltage source. There is one MMXU available for each
configurable source (programmed in the
from G60 source 1, and MMXU2 provides data from G60 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 G60 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.TotVAr: three-phase reactive power
