Introduction

Functional overview

The IEC101 OPC Server provides methods for OPC clients to exchange data with devices
communicating via the IEC 60870-5-101 Master protocol.

The IEC101 OPC Server software has two parts: Engineering and diagnostic tools and
the actual IEC101 OPC Server. Engineering and diagnostic tools utilize the SAB600
framework and provide the user interface for engineering and diagnosing the IEC101
OPC Server. The IEC101 OPC Server handles the data transfer and conversion between
the IEC101 protocol and OPC interfaces.
To create a common and protocol independent data interface between the OPC server
and client, the process data from the IEC101 devices is remodeled using the IEC 61850
data modeling.
The configuration data is stored in the SCL format. After the IEC101 OPC Server has
been launched, it reads the configuration file and establishes communication with the
IEC101 devices through the IEC101 protocol stack.
