to be included in each LN. This clause describes the general handling of the data objects
within the 650 series products.
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 650 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.
