Clause: 6.4.2.1

Paragraph: 6.4.2.1

Issue: The standard does not define how LD.LLN0.LocSta impacts to subordinate levels.

For LD.LLN0.Loc vs. LN.Loc a dominance statement can be found in Part 7-4 (see description to LLN0.Loc), but not for LocSta.

Proposal: The applicational idea expressed in the L/R concept to be detailed in Part 7-1, to allow a further refinement in Part 7-4 Annex B.

A definition may result in a future extension of the description for LLN0.LocSta:
"If this 'LocSta' (in the logical device) is in contradiction to the 'Loc.Sta' of any other contained logical node, control authority at station level is always dominant (see also Annex B)."
