Description
An SGCB, if it exists, are located in LLN0. ยง8.2.5: "If setting group control blocks are present, they shall appear only once in any branch of the logical device management hierarchy." Propose to extend this statement to state that the location of the SGCB in the LD hierarchy defines a border line; no SGCB can exist on a higher level. Parallel SGCB can exist.
- Standard(s) changed from IEC61850 7-1 Ed.2.1 to IEC61850 7-1 Ed2.1

NOT ALLOWED THIS MODELLING
ALLOWED:
LD1
+-- Distance Prot LD -> SGCB
+-- Overcurrent Prot LD -> SGCB
LD1 --> SGCB
+-- Distance Prot LD
+-- Overcurrent Prot LD
This could be checked with OCL.
There can only be one SGCB for the same hierarchy.
Decision: Raise this issue to WG10 to find out if it is safe to use both options. Maybe a clarification is needed.

Regarding clarification:
- Conformance tests are ok with the specification: Test UCA-Test-sCnf48
