CIM Issues #6451
Cardinality inconsistency for PowerElectronicsConnection<->PowerElectronicsUnit between canonical model and profile
61970-452
Description
The cardinality of PowerElectronicsConnection<->PowerElectronicsUnit is 1:0..* for the canonical model, while the cardinality is 1:0..1 at the profile level.
Proposed Solution
Solution is to:
- In the 301 for the UML change the cardinality from 1..1 to 0..1 on the PowerElectronicsConnection role end.
- In the 452 EQ profile change the direction of the association
- In the 452 EQ profile change the cardinality on the PowerElectronicsUnit role end to 0..*
Decision
Call 18 Oct 2023
it is not clear why we have the many side at the PowerElectronicsUnit. This does not match the pattern we have between GeneratingUnit and RotatingMachine. This will need follow up discussion.
14-Feb-2024 discussed further during the WG13 weekly call:
- In the 301 for the UML change the cardinality from 1..1 to 0..1 on the *PowerElectronicsConnection* role end.
- In the 452 EQ profile change the direction of the association
- In the 452 EQ profile change the cardinality on the *PowerElectronicsUnit* role end to 0..*
Release Notes
- In the 301 for the UML changed the cardinality from 1..1 to 0..1 on the PowerElectronicsConnection role end.
- In the 452 EQ profile changed the direction of the association
- In the 452 EQ profile changed the cardinality on the PowerElectronicsUnit role end to 0..*
