System Engineer ConfiguresIEC 61850 Gateway to DNP3 Substation1 Description of Function1.1 Function NameSystem Engineer Configures IEC 61850 Gateway to DNP3 Substation1.2 Function IDDNP3-IEC6850-21.3 Brief DescriptionGiven DNP-XML Device Profiles for a substation automation system consisting of multiple DNP3 devices, a system engineerconfigures a gateway device so an IEC 61850 Client can control and monitor the substation using IEC 61850.1.4 Narrative Text narrative still to be added Key issues include: How are points selected from the DNP devices? Is there an internal DNP3 point map in the gateway that can be used tospecify points? Should the final configuration of the gateway be performed using an SCD file, or by updating the DNP-XML files of thevarious devices?System Engineer Configures IEC 61850 Gateway to DNP3 Substation 2010-08-10.doc16/22/2011
