Section 7
Logical node data model
36
The mandatory data objects as defined in IEC 61850-7-4 as part of the Common
Logical Node are Mode, Behavior, Health and NamePlate.
Mode
The operation modes ON (enabled) and BLOCKED are supported remotely by a
command or from the LHMI of the service kit.
If the setting "RemoteModControl" is set to "Off" (default), all
remote writes to Mod will be rejected.
Behaviour
The operational mode as given by the Mode control is shown in the data object Beh
according to priority rules described for Beh in clause 6 of IEC 61850-7-4.
The Beh shows the actual state of the function depending on the hierarchy
described in clause 6 of IEC 61850-7-4.
It is possible that the behavior is influenced also by other sources independent from
the Mod, for example Insertion of the test handle, IED configuration tool
(PCM600), or LHMI.
In case the setting "operation" of a function is set to Off from the LHMI or
PCM600, the Beh will be set to Off independent of the value of the Mod.
The state Off can be set from the LHMI or the PCM600 for the functions having
the setting "operation".
Health
Health will reflect the current status of the IED HW and configuration. Possible
values are: OK, Warning, and Alarm.
Health indicates OK, Warning, or Alarm, depending on the IED status.
NamePlt
The name of the logical node and its relation to namespace definition are shown in
the data object NamePlt as specified for the SCL structure.
