The External OPC Server is intended for connecting external systems to the COM600
device with OPC. The external system needs an OPC DA Server with version 2.0 support.
The External OPC Server software has two parts: Engineering and diagnostic tools and
the actual External OPC Server. Engineering and diagnostic tools utilize the Station
Automation Builder 600 (later referred to as SAB600) framework and provide the user
interface for engineering and diagnosing the External OPC Server. The External OPC
Server handles the data transfer between the 3rd party OPC server and COM600 OPC
clients. It has OPC DA Client that connects to the 3rd party OPC server and OPC DA
and A&E server that publishes the data for the COM600 OPC clients.
To create a common and protocol independent data interface between the OPC server
and client, the process data from the 3rd party OPC server is remodeled using the
IEC61850 data modeling in the External OPC Server.
The configuration data is stored in the SCL format. After the External OPC Server has
been launched, it reads the configuration data and establishes the connection to the 3rd
party OPC server according the configuration.
