3.4.4.2 Generic Object Oriented Substation Event (Function Group GOOSE)
For high priority exchange of information between individual devices (IEDs) in a
local network, the P634 provides the function group GOOSE as defined in the
standard IEC 61850. GOOSE features high-speed and secure transmission of
information for reverse interlocking, decentralized substation interlock, trip
commands, blocking, enabling, contact position signals and other signals.
GOOSE Messages are only transmitted by switches but not by routers. GOOSE
messages therefore remain in the local network to which the P634 is connected.
3.4.4.2.1 Configuration and Enabling
Function group GOOSE can be configured by setting the parameter
GOOSE: Function group GOOSE This parameter is only visible if the optional
Ethernet communication module is fitted to the P634. After having configured the
GOOSE all parameters associated to this function group are then visible and
ready to be configured.
Further setting parameters from function group GOOSE are set with the
IED Configurator, but they cannot be modified from the local control panel (MMI)
or with the operating program.
The function can then be enabled or disabled by setting GOOSE: General
enable USER.

3.4.4.2.2 Sending GOOSE
The GOOSE can send up to eight different GOOSE messages which are managed
in eight GOOSE Control Blocks (gcb01 to gcb08). Information content depends on
the respective dataset assigned to GOOSE. The maximum size of a dataset to be
sent by GOOSE is limited to 1500 bytes. A control display is shown by the IED
Configurator to check this limit.
