26 Specific Mapping SCSM 1 IEC and its mapping opportunities IEC is the up to date, world wide accepted communication standard Mapping the data model and the services to different ISO/OSI layers Application ACSI SCSM 2 Application layer 7 Abstract Interface SCSM n Physical, Data Link, Network, Transport, Session, Presentation Layer 1-6 Key features of the standard: 1. Separation of data and communication technology - keep the information (application) free from any information exchange method and communication network 2. Communication stacks may be exchanged following the state of the art in communication technology - one specific mapping defined to MMS and Ethernet TCP/IP - generally the standard is open for other transmission media like PLC or radio transmission communication stacks 3. Information models can be easily extended - further extension planned i.e. for wind power plants, distributed power stations, and water power stations Page 26
