Clause: 15.2.2.6

Paragraph:

Category: Issue for edition 2 of this part

Issue

Accordign to 7-2 15.2.2.6 the SetGoCBValue service allows to set GoEnable, ApplicationID and DatasetReference. 8-1 only allows to write GoEnable. This should be harmonized, or the reason explained.

Proposal

In general a dynamic reconfiguration of safety critical GOOSE traffic is dangerous. Therefore either adapt 7-2 to 8-1, or make a statement that this changes should only be allowed on a safe communication link, i.e. after the security issues have been solved and standardized.

Discussion Created Status
All attributes have to be present according to 8-1, so the consistancy is granted; but which attributes ApplicationID, DatasetReference,... is writable by a client is a local issue. The r attribute only specifies that it has to be present and readable, not that it shall be only read only.
