CHAPTER 5: SETTINGS
The following is a summary of LNs that are in each Logical Device (LD2 through LD7):
• PxxxMMXU1 ClcMth = P-Class (Note Vaux is mapped to Vneut of MMXU)
• PxxxMSQI1 ClcMth = P-CLASS
• MxxMMXU1 ClcMth = M-Class (Note Vaux is mapped to Vneut of MMXU)
• MxxMSQI1 ClcMth = M-CLASS
• NxxMMXU1 ClcMth = M-Class (Note Vaux is mapped to Vneut of MMXU)
• NxxMSQI1 ClcMth = M-CLASS
• GGIO1, which contains 16 digital status indication points and 16 analog points. The Analog GGIO values are selectable
from any FlexAnalog value in the UR.
The Synchro Logical Nodes in an LD report at the same rate as set in the PMUn Basic Configuration setting. This
is reflected in the instantiation of the Data Object – SmpRate in the msvcb## of LLN0 in the LD1. SmpRate is a
NOTE Read Only Integer Status (INS).
When the first PMU from any LD is mapped into an aggregator, the aggregator inherits the Sample Rate (SmpRate) and
IEEE C37.118 Class (P or M) of that PMU. The value of the SmpRate DO in the Report Control Block is set based on the value
of the Sample Rate in the PMU. The Class of the Dataset are mapped into the MSVID of the Dataset (see text that follows for
the overall name of the MSVID). If other PMUs are mapped into the same aggregator with different Sample Rates or from
different classes, then a Self-Test error (DatSetErr) is set and dataset transmission is blocked.
A setting value — MSVID — is created with a maximum input range of 56 characters (=64 less 6 for the IDCode less 2 for the
Class).
The value of MSVID in the dataset is a concatenation of the aggregator IDCode and the MSVID setting value in the format:
MSVID-AggregatorIDCode-CLASS where CLASS is P, M, or N (for None) – depending on the Class of the first PMU included in
the Aggregator.
