an increased frequency to ensure the timeliness of its reception. The transmission then
gradually tapers off to the original frequency with the new data.
In GOOSE, data sending is based on data sets and GOOSE control blocks. The data set
defines what device data is used in GOOSE service and sent to local Ethernet
subnetwork in a GOOSE message. The GOOSE control block links the data set and its
attributes to actual data.

Configuring GOOSE with the IEC 61850
Configuration tool
See detailed descriptions of the steps in corresponding chapters.
1. Add devices to a PCM600 project.
2. Engineer the GOOSE connections between the devices.
Description
A multicast addressing scheme is used when sending GOOSE
messages. A multicast address can be shared by several sending
devices, or it can be device specific. To keep the multicast message
filtering of the devices working it is recommended to use unique multicast
addresses.
APPID is a GoCB-specific integer value identifying the sender GoCB and
its data. The APPID must be unique for the GoCB in the system. The
priority can be used according to the local network priority scheme, but
normally the default value is sufficient. The VLAN group can be used
when configuring the Ethernet network topology Virtual LANs for routing
and filtering multicast messages. Configuration is done in managed
Ethernet switches.
The name of the GoCB structure seen from the IEC 61850/MMS client.
Some devices use this as a unique data reference.
A GOOSE control block specific string. The default value is the GoCB
path in the 61850 namespace if nothing is set. It is recommended to
always set a unique value in tool.
Check the GOOSE Control block GoID name according to the system
requirements of the receiving device. Although the protection relays use
MAC address and APPID for receiving packet detection, some devices
require additionally that the GOOSE control block GoID is named
explicitly.
Data sent in GOOSE messages to the network.
ConfRev increases when the referenced data set is modified. Both the
GOOSE sender and the receiver must have the same ConfRev value.
This ensures that the both devices have the same configuration level in
the substation configuration. ConfRev usage is done automatically by
tools. If the latest system configuration is not downloaded to all required
devices, the configuration revision may differ between the receiver and
sender and data exchange does not work.
