2 LOGICAL NODES

A–4
The tables in this section use the following abbreviations:
• M: Data is mandatory in the IEC 61850-7-4.
• O: Data is optional in the IEC 61850-7-4 and is used in the device.
• C: Data is conditional in the IEC 61850-7-4 and is used in the device.
• E: Data is an extension to the IEC 61850-7-4.
• AC_CO_M: The attribute is mandatory, if the controllable status class supports control.
• AC_CO_O: The attribute is optional, if the controllable status class supports control
• AC_ST: The attribute is mandatory, if the controllable status class supports status
information.
• AC_LN0_M: The attribute shall be present if the data NamPlt belongs to LLN0
• AC_DLD_M: Applies to lnNs in all CDC LPL only, shall be present if LN name space of
this LN deviates from the LN name space referenced by ldNs of the logical device in
which this LN is contained.
• AC_DLN_M: Applies to dataNs in all CDCs, dataNs shall be present if the name space of
the DATA deviates from the name space defined in ldNs/lnNs
• AC_DLNDA_M: Applies to cdcNs and cdcName in all CDCs only, shall be present if CDC
name space of this data deviates from the CDC name space referenced by either the
dataNs of the data, the lnNs of the logical node in which the data is defined or ldNs of
the logical device in which the data is contained.

3 SERIES PROTECTIVE RELAY PLATFORM – COMMUNICATIONS GUIDE
1: when normal. (No errors)
2: when minor error is
present (e.g. "High ENET
Traffic" alarm)
3: when major error is
present. (e.g. "Error Code 1"
or "RELAY NOT READY")
