IEC 61850 and its mapping opportunities

IEC 61850 is the up to date, world wide accepted communication standard Mapping the data model and the services to different ISO/OSI layers

Key features of the standard:

Application 1. Separation of data and communication technology - keep the information (application) free from ACSI Abstract Interface any information exchange method and communication network 2. Communication stacks may be exchanged Specific SCSM 2 SCSM n SCSM 1 following the state of the art in Mapping communication technology - one specific mapping defined to MMS Application layer 7 and Ethernet TCP/IP - generally the standard is open for other Physical, Data Link, Network, Transport, Session, Presentation Layer 1- 6 transmission media like PLC or radio transmission 3. Information models can be easily extended communication stacks - further extension planned i.e. for wind power plants, distributed power stations, and water power stations
