Function modeling - Problem
LN semantic provides the semantic of the class, but not of the instance – XSWI is a disconnector – but which one?
– PDIS is a distance element – but which zone?
–Which one is the earth fault, which one the phase fault?
Prefixes may be used (e.g. QB1XSWI) but are not standardized

SCL Extensions required
Support virtual signal flow as part of specification – In the functional part of SCL / independent of IEDs
– Using SourceRef in a similar way as ExtRef
– Include support of value preconfiguration
IED specification – Extend SCL to support IED specification beyond 61850 related
aspects

Conclusion
Significant work is done to enhance the design and engineering efficiency
Users and vendors collaborate to achieve the goal – the ENTSO-E approach is currently prototyped in the European Research Project OSMOSE
