3.4.4.1.9 Fault Transmission
Including fault transmission for the IEC 61850 in the configuration is only possible
with the IED Configurator.
Transmission of fault files is supported per “File Transfer”. COMTRADE fault files
in the P631 are transmitted uniformly either as ASCII or binary formatted files.
Fault transmission can be cancelled from the configuration.
3.4.4.1.10 High Priority Transmission of Information
Whereas normal server-client services are transmitted at the MMS and TCP/IP
level the high priority transmission of information is carried out directly at
Ethernet level. Furthermore messages in such a particular form can be received
by all participants in the relevant sub-network, independent of their server or
client function. They are deployed in instances where high speed transmission of
information is wanted between two or more devices. Applications, for example,
are reverse interlocking, transfer trip or decentralized substation interlock.
The standard IEC 61850 provides two modes for high priority transmission of
information: the GSSE and the GOOSE. The GSSE (also named UCA2-GOOSE ) is
used to transmit binary information with a simple configuration by 'bit pairs', and
it is compatible with UCA2. The GOOSE enables transmission of all data formats
available in the data model, such as binary information, integer values, two-pole
contact position signals or analog measured values. The P631 supports receipt
and evaluation of GOOSE including binary information and two-pole contact
position signals from external devices.
3.4.4.1.11 Communication with the MiCOM S1 Support Software via the Ethernet Interface
Direct access by the MiCOM S1 support software via the Ethernet interface on
the P631 may occur through the “tunneling principle”. Transmission is carried
out by an Ethernet Standard Protocol, but this is only supported by the
associated MiCOM S1 support software (specific manufacturer solution). Such
transmission is accomplished over the same hardware for the network, which is
used for server-client communication. Available are all the familiar functions
offered by the MiCOM S1 support software such as reading/writing of setting
parameters or retrieving stored data.
