The master protocol and OPC server layers are runtime software components. The IEC
61850 data model is built based on the imported SCL file using Station Automation
Builder 600 (SAB600). To simplify the protocol conversion and the signal mapping,
each master protocol OPC server uses the same common data modeling (common data
classes and services) specified in the IEC 61850 standard. The COM600 configuration
data is also in SCL (XML-based) format.
After the master protocol OPC server is launched, it reads the configuration data and
establishes communication with the slave devices through the master (client) protocol
stack. Configured slave devices and their data are then exposed to OPC clients (Web
Server, slave protocols etc.) through the master protocol OPC server. The slave devices'
reported data changes together with Data Access subscription are reported to the sub-
scribing OPC clients.
The Master protocol OPC server component handles the data transfer and conversion
between the underlying master protocol communication stack and OPC interfaces.

IEC 61850 OPC Server features

The IEC 61850 standard is a set of specifications, which detail a layered approach to
substation communication architecture. It specifies the usage of Manufacturing Message
Specification (MMS, ISO 9506) between the IEC 61850 server (slave devices) and IEC
61850 client (IEC 61850 OPC Server, master). The COM600 IEC 61850 OPC server
can subscribe to both MMS and GOOSE based data. However, it can only send MMS
based command information to the slave devices.
