Figure 2.2-1 Functional overview of IEC 61850 Proxy Server
IEC 61850 Proxy Server enables IEC 61850-8-1 MMS clients to access data and services
of COM600. It also features a GOOSE send functionality for publishing data. With these
features, it is possible to connect non-IEC61850 IEDs to the IEC 61850 network via
COM600. Also calculated data from COM600 (e.g. from logic processor) can be published
to IEC61850 network using the IEC 61850 Proxy Server.
IEC61850 Proxy Server is configured using the Proxy Configuration tool in SAB600.
The Proxy Configuration tool shows a list of IEDs and their logical devices that are
configured to COM600. You can select which of them will be added to the IEC61850
Proxy Server configuration. As the COM600 native data model is according to the IEC
61850 standard, complicated cross-reference configuration is not required. You can later
adjust the data set and reporting configuration. The IEC 61850 Proxy Server configuration
is stored into an SCL file, which is loaded to the COM600. The configuration can also
be exported to an SCL SCD file, which can be used for the IEC 61850 client configuration.
When the IEC 61850 Proxy Server is started, it first reads and parses the SCL configur-
ation. It creates the IEC 61850 data model according to the SCL and establishes connec-
tions to the related COM600 OPC servers. It initiates a refresh for the OPC servers to
update all configured data. After the data is received, the IEC 61850 Proxy Server has
up-to-date data from the underlying process and the IEC 61850 server is started. The
IEC 61850 Proxy Server starts normal operation. During normal operation the actions
