The L60 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 L60 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 L60 will continue to
block transmission of the dataset. The L60 will assert the

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:
1. Configure the transmission dataset.
2. Configure the GOOSE service settings.
3. Configure the data.
The general steps required for reception configuration are:
1. Configure the reception dataset.
2. Configure the GOOSE service settings.
3. Configure the data.
This example shows how to configure the transmission and reception of three IEC 61850 data items: a single point status
value, its associated quality flags, and a floating point analog value.
The following procedure illustrates the transmission configuration.
1. Configure the transmission dataset by making the following changes in the

settings menu:
– Set

to “GGIO1.ST.Ind1.q” to indicate quality flags for GGIO1 status indication 1.
– Set
ITEM 2
to “GGIO1.ST.Ind1.stVal” to indicate the status value for GGIO1 status indication 1.
The transmission dataset now contains a set of quality flags and a single point status Boolean value. The reception
dataset on the receiving device must exactly match this structure.

settings menu:

to “Enabled”.
– Set
CONFIG GSE 1 ID
to an appropriate descriptive string (the default value is “GOOSEOut_1”).
– Set
CONFIG GSE 1 DST MAC
to a multicast address (for example, 01 00 00 12 34 56).
– Set the
CONFIG GSE 1 VLAN PRIORITY
; the default value of “4” is OK for this example.
– Set the
CONFIG GSE 1 VLAN ID
value; the default value is “0”, but some switches may require this value to be “1”.
– Set the
CONFIG GSE 1 ETYPE APPID
value. This setting represents the ETHERTYPE application ID and must match
the configuration on the receiver (the default value is “0”).
– Set the
CONFIG GSE 1 CONFREV
value. This value changes automatically as described in IEC 61850 part 7-2. For
this example it can be left at its default value.
