Implementation of OPC server for SNMP network monitoring on FACTS  equipment

Abstract: The goal of this thesis work was to implement a functional OPC server monitoring network devices in ABB/FACTS applications through the SNMP protocol. The work was divided into four different parts, analysis, design, implementation and verification. Different OPC server source codes and different SNMP libraries were analysed. After completing the analysis, Advosol source code and an SNMP library by Oliver Griffet was chosen. The design included determining which SNMP information was relevant. By choosing the relevant information in an early stage, the implementation phase was programming and done in a Visual Studio environment in C#. During the implementation phase the author also got familiarized with InTouch for the HMI window where the SNMP information was shown. A specific SNMP information window was also created in the user interface within InTouch. By implementing the SNMP library within the OPC server the author was able to demonstrate a working application concept at the end of the thesis work.
