IEC 61850 Overview
AX-S4 MMS
AX-S4 MMS ("Access for MMS") is complete ready to run IEC 61850 interface for Windows applications. AX-S4 MMS includes IEC 61850 client functions supporting OPC and DDE, an interactive object browser for device testing and setup, IEC 61850 server functions for implementing data concentrators and gateways, a GOOSE for publishing and subscribing to IEC 61850 GOOSE and GSSE messages. AX-S4 MMS makes using IEC 61850 for OPC applications easy by simplifying the controls and reporting functions of IEC 61850 to provide an interface optimized for OPC applications. AX-S4 MMS supports all IEC 61850 ACSI services for reporting, controls, logical devices, logical nodes,
variables, datasets, object discovery, logs, files, and GOOSE/GSSE.
MMS-EASE Lite
MMS-EASE Lite is a flexible source code implemntation supporting IEC 61850 client and server functions 
that has been optimized for use in Intelligent Electronic Devices (IEDs) such as relays, RTUs, reclosers, PLCs, meters and other resource constrained embedded applications. MMS-EASE Lite supports all relevant parts of the IEC 61850 standard including support IEC 61400-25 wind power models, distributed energy resource (DER) models of IEC61850-7-420, and IEC 61850-7-410 hydro power models. MMS-EASE Lite is easily portable to any computing platform to support IEC 61850, (UCA2 per IEEE TR1550), and MMS. ICCP-TASE.2 extensions for MMS-EASE Lite are also available for IEC 60870-6 TASE.2 support.
