IEC 61850 data modelling
To simplify protocol conversion and signal mapping in the gateway, each
component uses a common data model. The data model is based on common data
classes and services specified in the IEC 61850 standard. Each client and server
component is a separate program. The components interact with each other only via
OPC interfaces. This means that they can be developed and used independently as a
part of the gateway as long as they conform with the OPC DA and common data
model specifications.
