1223   LGOS GoCBRef values

Issue

The GoCBRef has CDC=ORG. The ORG has a mandatory setSrcRef and optional setSrcCB. It is not obvious what the values should be of these attributes. Are both attributes required? Is the object reference value with/without FC? And using "." or "$"?

Proposal

I propose just LGOS.GoCBRef.setSrcRef, no FC with ".":

<DOI name=”GoCBRef”>
<DAI name=”setSrcRef”>
<Val>IEDnameLD/LLN0.GooseControlBlock</Val>
</DAI>
</DOI>

Discussion Created Status
The returned value is exactly the set value, i.e. no $ - again to assure independency of the using applications from the (MMS) mapping. 13 Jul 15 Not Applicable
Assuming setSrcRef DA has <Val>IEDnameLD/LLN0.GooseControlBlock</Val> in SCL, what value should be returned for MMS read to DA setSrcRef ?
IEDnameLD/LLN0.GooseControlBlock
OR
IEDnameLD/LLN0$GO$GooseControlBlock ? 		13 Jul 15 Not Applicable
The proposed reference value syntax is according to parts 6 and 7-2 the correct one. It is used to assure independency of 61850 names / references from stack mappings.
setSrcRef is the 'object reference'. As here the object is a control block reference, setSrcCB is superfluous and shall not be provided. Thus the example given in the proposal is correct. 		04 Mar 14 Not Applicable
