- further extension planned i.e. forwind power plants, distributed power stations,

and water power stations

1. Separation of data and communication technology

3. Information models can be easily extended

2. Communication stacks may be exchangedfollowing the state of the art incommunication technology

- keep the information (application) free fromany information exchange method andcommunication network

- one specific mapping defined to MMSand Ethernet TCP/IP

- generally the standard is open for othertransmission media like PLC or radio transmission

Key features of the standard:

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