5.2 PRODUCT SETUP
The GOOSE functionality was enhanced to prevent the relay from flooding a communications network with GOOSE mes-
sages due to an oscillation being created that is triggering a message.
The F35 has the ability of detecting if a data item in one of the GOOSE datasets is erroneously oscillating. This can be
caused by events such as errors in logic programming, inputs improperly being asserted and de-asserted, or failed station
components. If erroneously oscillation is detected, the F35 will stop sending GOOSE messages from the dataset for a min-
imum period of one second. Should the oscillation persist after the one second time-out period, the F35 will continue to
block transmission of the dataset. The F35 will assert the
sage on the front panel display, where
For versions 5.70 and higher, the F35 supports four retransmission schemes: aggressive, medium, relaxed, and heartbeat.
The aggressive scheme is only supported in fast type 1A GOOSE messages (GOOSEOut 1 and GOOSEOut 2). For slow
GOOSE messages (GOOSEOut 3 to GOOSEOut 8) the aggressive scheme is the same as the medium scheme.
The details about each scheme are shown in the following table.

The configurable GOOSE feature is recommended for applications that require GOOSE data transfer between UR-series
IEDs and devices from other manufacturers. Fixed GOOSE is recommended for applications that require GOOSE data
transfer between UR-series IEDs.
IEC 61850 GOOSE messaging contains a number of configurable parameters, all of which must be correct to achieve the
successful transfer of data. It is critical that the configured datasets at the transmission and reception devices are an exact
match in terms of data structure, and that the GOOSE addresses and name strings match exactly. Manual configuration is
possible, but third-party substation configuration software may be used to automate the process. The EnerVista UR Setup
software can produce IEC 61850 ICD files and import IEC 61850 SCD files produced by a substation configurator (refer to
the IEC 61850 IED configuration section later in this appendix).
The following example illustrates the configuration required to transfer IEC 61850 data items between two devices. The
general steps required for transmission configuration are:
