GOOSE Analyzer Operator's Manual
The counter is incremented when the configuration changes. At configuration time, the
configuration tool is responsible for incrementing/maintaining the ConfRev value. When
configuration changes occur due to SetGoCBValues, the IED is responsible for incre-
menting the value of ConfRev. If the value of DatSet is set through a SetGoCBValues
service to the same value, the ConfRev value is still to be incremented.
The initial value for ConfRev is outside the scope of this part of IEC 61850. Value 0 is
reserved. The value of ConfRev, when the IED is restarted, is a local issue.
The ConfRev analyzer compares the ConfRev contained in the received GOOSE message
(packet) with that in the SCD based on the reference of the GOOSE control block. In
normal status, the ConfRev conforms to the value in the configuration.
When a ConfRev mismatch is detected, the analyzer issues a specific diagnostic event
to warn users of the status transition.
NdsCom analyzer
The NdsCom attribute has the value TRUE if the GoCB requires further configuration.
Further configuration is required in the following cases:
•
The attribute DatSet has the value NULL.
•
The number or size of values conveyed by the elements in the data set referenced
by DatSet exceeds the constraint determined by the SCSM or the implementation.
When the NdsCom bit changes, the analyzer verifies the NdsCom bit contained in the
received GOOSE message (packet) and issues a specific diagnostic event to warn users
of the status transition.
Simulation analyzer
Simulation indicates with the value TRUE that a message and its value have been issued
by a simulation unit. The GOOSE subscriber reports the value of the simulated message
to its application instead of the "real" message depending on the setting of the receiving
IED.
When the simulation bit changes, the analyzer verifies the simulation bit contained in
the received GOOSE message (packet) and issues a specific diagnostic event to warn
users of the status transition.
Disorder analyzer
Disorder means that StNum and SqNum for GOOSE packets from the specific GOOSE
Control Block are not in series.
