GOOSE is used in substation automation for fast horizontal communication

between the IEDs. GOOSE can be used for direct data exchange, for example, of

interlocking and blocking information between IEDs. According to the IEC

61850-8-1 standard, GOOSE uses a publisher/subscriber profile in which

information is shared from one IED to one or several IEDs by using Ethernet

multicast messages. A message is an image of a sent IEC 61850 data set that is

defined in the configuration.

IET600 is used to configure the vertical and horizontal communication properties

of the 615 series IEDs.

A 615 series IED can send any type of status or measurand data in the GOOSE

messages from its IEC 61850 data model. The status data response time, that is, the

time it takes for the application to handle a received GOOSE message and to send

the concerned data back to the network, is with the 615 series IEDs below 3 ms.

The response time fulfils the tightest Type 1A, Class P2/3 requirements of the

standard.
