7.2 IEC 61850 PROFILE FOR F650
CHAPTER 7: IEC 61850 PROTOCOL
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.
N source MAC address
Y destination MAC address (Should be multicast, if it is not
multicast the status of the internal variable “Remote
Device” goes to OFFLINE)
N VLAN id
N VLAN priority
Y Ethertype = 0x88B8
N APPID
Y gocbRef (should match setting, if not the status of the
internal variable “Remote Device” goes to OFFLINE.)
N timeAllowedtoLive
Y datSet (should match setting, if not the status of the
internal variable “Remote Device” goes to OFFLINE)
Y goID (should match setting, if not the status of then
internal variable “Remote Device” goes to OFFLINE)
N t
N stNum
N sqNum
N test
Y confRev (should match setting, if not the status of the
internal variable “Remote Device” is not affected but the
incoming data from GOOSE message is ignored)
Y ndsCom (should have value FALSE, if it has value TRUE
the status of the internal variable “Remote Device” is not
affected but the incoming data from GOOSE message is
ignored)
Y numDatSetEntries (should match expected number of
data set entries, if not the status of the internal variable
“Remote Device” is not affected but the incoming data
from GOOSE message is ignored)
Y allData (should match expected data set, if not the
status of the internal variable “Remote Device” is not
affected but the incoming data from GOOSE message is
ignored)
What is the behaviour when one subscribed GOOSE
message isn’t received or syntactically incorrect (missing
GOOSE)
A single “missing” or syntactically incorrect GOOSE
message is ignored.
What is the behaviour when one subscribed GOOSE
message exceeds the previous time Allowed to Live (TAL)
A single late GOOSE message does change the status of
the internal variable “Remote Device” to OFFLINE.
What is the behaviour when a subscribed GOOSE
message is out-of-order
Sequence number is ignored the message is accepted.
What is the behaviour when a subscribed GOOSE
message is duplicated
N Sequence number is ignored the message is accepted.
Additional Items:
Maximum number of GOOSE messages that can be sent 4
Maximum number of GOOSE messages that can be
received
8
Interpretation of quality at subscriber side
Quality is not required to be in the data set. If configured
in data set and received its value is by default ignored.
However it is possibe to map quality to Bistring13 object
at subscriber side and then use any of its 13 bits.
Restrictions on Data Set elements for transmission GOOSE Data Set elements for transmission GOOSE have to be
Data Attributes (leaf objects). The exception to this rule is
FixedGOOSE (only use between GE devices).
