PIXIT for GOOSE subscribe model

ID Ed Description
Gs1 1,2 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 a ethernet switch and shall not be
checked
- the simulation flag shall always be checked (Ed2)
- the ndsCom shall always be checked (Ed2)
Gs2 1,2 When is a subscribed GOOSE marked as lost
(TAL = time allowed to live value from the last received GOOSE message)
Gs3 1,2 What is the behaviour when one or more subscribed GOOSE messages
isn't received or syntactically incorrect (missing GOOSE)
Gs4 1,2 What is the behaviour when a subscribed GOOSE message is out-of-
order
Gs5 1,2 What is the behaviour when a subscribed GOOSE message is duplicated Message will be ignored
Gs6 1 Does the device subscribe to GOOSE messages with/without the VLAN
tag
Gs7 1 May the GOOSE data set contain:
- structured data objects (FCD)
- timestamp data attributes
Gs8 1,2 Subscribed FCD supported common data classes are
Gs9 1,2 Are subscribed GOOSE with test=T (Ed1) / simulation=T (Ed2) accepted in
test/simulation mode
Gs10 1 What is the behaviour when a subscribed GOOSE message with TAL = 0 is
received by the subscriber.
Gs11 1 What is the behaviour when a subscribed GOOSE message hasn't the
