OpenPLC is an open-source software that complies
with IEC 61131-3 international standard and has been widely used by researchers
to validate PLC logic execution. However, the software’s capability is limited
as it is solely restricted to Modbus and DNP3 protocols. With the integration
of intelligent electronic devices (IEDs) into modernized power grid based on
IEC 61850 standards, it is necessary to incorporate functionalities that enable
PLCs to communicate with IEDs. Therefore, in this paper we develop OpenPLC61850,
which is an extended version of OpenPLC and is compatible with the IEC 61850 protocol.
The architecture and the procedure involved with PLC logic execution, IED
communication, and SCADA connectivity are explained in this paper. As the
proposed software is also an open source, we believe that this would be helpful
for researchers for conducting smart grid research.
