What elements of a subscribed GOOSE header are
checked to decide the message is valid and the
allData values are accepted? If yes, describe the
conditions.
Notes:
• The VLAN tag may be removed by an Ethernet switch
and shall not be checked
• The simulation flag shall always be checked (Ed2)
• The ndsCom shall always be checked (Ed2)

When is a subscribed GOOSE marked as lost?
(TAL = time allowed to live value from the last received
GOOSE message)
Message does not arrive prior to TAL
Gs3
1,2
What is the behavior when one or more subscribed
GOOSE messages is not received or syntactically
incorrect (missing GOOSE)?
When a subscribed GOOSE is marked
as lost, a Self Test Alarm target is
generated, and all internal data that is
derived from GOOSE data is configured
to default values
Gs4
1,2
What is the behavior when a subscribed GOOSE
message is out-of-order?
Sequence number order (with no state
number change) is not checked. State
number order is checked; the older
message is ignored.
Gs5
1,2
What is the behavior when a subscribed GOOSE
message is duplicated?
Duplicate message is ignored
Gs8
1,2
Subscribed FCD supported common data classes are... All FCDs that are defined by GOOSE
publishers in the CID file.
Arrays are supported.
