Application layer 7

- further extension planned i.e. for wind 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 exchanged following the state of the art in communication technology

- keep the information (application) free from any information exchange method and communication network

- one specific mapping defined to MMS and Ethernet TCP/IP

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

Key features of the standard:

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