1340   An ambiguous sentence

Created: 23 Dec 2014

Status: Triage

Part: Part 8-1 (2004)


Page: 32

Clause: 7.3.1

Paragraph: 8

Issue: It is written there:
"Common data classes, which have a single attribute, shall be mapped to a MMS primitive data type, unless otherwise specified. The component name shall be the attribute name from IEC 61850-7-3 unless otherwise specified."
What does it mean?
As I understood, if we have the following object references of an ACSI model:
/GGIO1.SPCSO.ctlModel [CF] – The only mandatory atrribute of the CDC SPC

should be mapped to MMS structure as follows:

/GGIO1$CF$SPCSO – This structure should be absent because it’s CDC of the single attribute!
/GGIO1$CF$SPCSO$ctlModel – Unstead, This is the single attribute with primitive data ENUMERATED

This treatment is my mistake?

Proposal: Please, specify the detailed semantics of this.
