This way, up to 10 different clients can dispose of the whole information of events and
measures.
GOOSE
Goose service allows the Multicast sending (to multiple devices) of the existing information
in a Dataset.
Goose message is an Ethernet message that is continuously cast to the Ethernet and
every device can analyze it.
Standard SILA disposes by default a Goose message associated to the Goose Dataset:
This message is sent to the Ethernet with a latency time of 30 seconds till one of the
values of the element of the Dataset changes, then the message is sent immediately in a
repeating way in a short time, increasing till reaching the latency time.

10.3. Operation

Standard SILA is pre configured with a sample configuration to be integrated in an IEC
61850 system.
It disposes all the Data model with all the functionallity available via MMS (using a
software application like IEDScout) or via Reports (with their Event, measure or Trip
Datasets) in case a client needs to receive information from the device.
To retrieve the data model from the device to a PC with an IEC 61850 tool, it is only
required the IP of the device (by default 192.168.0.121).The tool has to be able of asking
the data model automatically.
The name of the IED is by default TEMPLATELD1 and below it there is the data model
with its logical nodes, data objects and data attributes according IEC 61850.
The common way to integrate a new IED in a SCADA is using reports and the ICD files
from SILA provided for this purpose.
From the ICD file of SILA, the client device has to select a Report with the associated
Dataset. This way, client will have a list of signals that will use to configure its own
database. Once client device is configured, the communication between server could be
initiated by the client by enabling the report and receving the existing information from the
report.
Each client has different ways of configuring, so it will be necessary referring to
IEC61850's configuration chapter from the client's manual.
Goose message is activated by default and is published with the information from the
Goose dataset (General Trips and Starts) into the net.
One IED that requires the information from a Goose has to be configured using the ICD
file from SILA. In this file appears the default parameters of the Goose message.
