GOOSE message format:
(This table has been taken directly from the IEC 61850 Standard document)
Although this entire GOOSE message is received, the gateway will only store
GOOSEData [1...n] in the tag database.
GOOSE Priority
The gateway gives GOOSE messages processing priority over other IEC data
messages. If a GOOSE message is received, the GOOSE message is processed
ahead of all other data transfer (MMS, Reporting) in the gateway at that moment.
GOOSE Subscription Status
The gateway’s GOOSE subscription verifies match of confRev in a manner
identical to the verification performed when enabling a report.
If the confRev does not match (unavailable, wrong type, different value), then the
GOOSE is not subscribed and an Event is logged in the Event Logger describing
the reason.
If the data type of confRev fetched from the IEC device is not RT_UNSIGNED,
then no event is logged.
The command, confRev must match what is running in the IED when the
gateway comes on-line with the current configuration, or the gateway will not
successfully subscribe to the GOOSE message.
The gateway does not check for a match of the GOOSE appid from the CID file
to the actual running IED when performing a GOOSE subscription.
