Logical Nodes For Automatic Control; Automatic Tap Changer Control Atcc - ABB Relion 630 Series Communication Protocol Manual

Section 7
Logical node data model
7.2
7.2.1
38
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 locally from the LHMI of the IED. The TEST and the TEST/BLOCKED
mode can be operated locally from the LHMI or by using PCM600.
The state OFF can be set from the LHMI or by using PCM600 for the functions having
the setting 'operation'.
Note also that for functions in other Logical devices than LD0, the Mod can only be
controlled by communication on LLN0.
Behaviour
The operational mode as given by the Mode control is shown in the data object Beh
with the priority rules as described for Beh in clause 6 of IEC 61850-7-4.
The Beh shows the actual state of the function, dependent upon the hierarchy
described in IEC 61850-7-4, clause 6.
Health
The 630 series products show always only the state "green" = Ok.
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.
