Improvement #441
Limitations of one to one mapping between LNode and LN

Category:
Standard clarification required
TF Unique ID:
4 # Vattenfall
WG10 Proposal:
to be adressed to the 61850-6-100 (need a realistic date)6-100 states that n:1 relationship between LNodes and LNs is allowed and supported. No need to change the SCL scheme for this.
Estimated Completion:
End of 2023
Discuss in Upcoming Meeting:
No
Short Proposal:
Discussed with TF SCL function modelling.
Needs More Information:
No
Assigned TF:
61850-6-100 (Function modeling)
Description
The Standard requires a one to one mapping between LNode and LN. This creates serious limitations. Examples:
1. Let us assume vendor makes use of GGIO and represent a 32 bit BI/O Interface Card in the IED with the LN BIO32GGIO1. Now in my Substation section I define two Functions with Fun1/BIOGGIO1, Fun2/BIOGGIO2. Fun1 and Fun2 are two very different functions, but I have only one BIO card in my IED. Now I would like to map the LNode Fun1/BIOGGIO1 to LN BIO32GGIO1 and Fun2/BIOGGIO2 also to LN BIO32GGIO1. Naturally they use distinct Data Attributes.
2. It is easy to find a similar example for MMXU. Power Measurement and Current/ Voltage Measurement can be used in different Functions in the Single Line, but are using the same LN MMXU.

6-100 does not cover the issue completely. Relation LNode - LN is 1:1, but what it is possible is to map remaining DOs not covered by mapped LN to DOs of other LN.

Solution is incorporated in the 90-30. Mapping is done on DO level (not LN level) which increase flexibility.
