GOOSE Analyzer Operator's Manual
VLAN tag analyzer
VLAN tag analyzer allows users to check the existence of a VLAN tag in the GOOSE
frames, in case a VLAN tag is not supported and removed by ethernet switches. When
a VLAN tag is missing from the GOOSE frames, the analyzer issues a specific event to
warn users of the status transition.
Timeout (flow status) analyzer
The timeout attribute of GOOSE messages indicates whether the association to the
GOOSE publisher is lost or not. A timeout alarm usually indicates a break in the com-
munication bus, a power-down in an IED, or other problems. It is a crucial parameter
for validating the correct operations of distributed functionalities.
The timeout analyzer checks the time interval between the previous GOOSE message
and the current one. In normal status, the interval is within the configured due time.
Otherwise, a timeout is detected and the analyzer issues a specific diagnostic event to
alarm users of such status transition.
DatSet reference analyzer
The attribute DatSet represents the reference of the data set whose values are transmitted.
The members of the data set are uniquely numbered starting with 1. This number is called
the MemberOffset of a given member. Each member of the data set has a unique number
and a MemberReference, Functional Constraint Data (FCD), or Functional Constraint
Data Attribute (FCDA).
The DatSet reference analyzer compares the DatSet 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 DatSet reference conforms to the value in the configuration.
When a DatSet mismatch is detected, the analyzer issues a specific diagnostic event to
warn users of the status transition.
ConfRev analyzer
The attribute ConfRev represents the number of times that the configuration of the data-
set referenced by DatSet has been changed.
Changes to be counted are:
•
Deleting a member of the data set
•
Adding a member to the data set
•
Reordering members of the data set
•
Changing the value of the attribute DatSet
