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 B30 current and voltage source. There is one MMXU available for each con-
figurable source (programmed in the
from B30 source 1, and MMXU2 provides data from B30 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 B30 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:
