The only TrgOp (trigger options) is dchg (data change). So GSE data is being
passed from the publisher to the subscriber only:
a) when the IED first enters the network
b) when the data changes on the publisher
You can set up GOOSE messages in the IEDs for only that data needs to be
sent to the gateway. That way, GOOSE messages contains only needed data.
GOOSE message format:
{This table has been taken directly from the IEC 61850 Standard document.}
Although this entire GOOSE message is received, the gateway only stores
GOOSEData [1..n] in the tag database.
GOOSE Messages
The gateway implements GSE messages according to IEC 61850-7-2 Clause 15.
The IEC 61850 driver acts as a Client, subscribing to the messages. The IEDs
act as a servers, publishing the messages.
GSE messages can help activate equipment safety interlocks (the IED prevents
harming the operator or itself).
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.
