326 Order of data in SGCB is not defined
Created: 24 May 2006
Status: Not Applicable
Part: Part 8-1 (2004)
Issue: The document does not specify anything on how to arrange the data of the SGCB. If we go as per section 7.3.1 of IEC61850-8-1 (page32), still it is not clear how to represent FC=SG coming under different LNs. We can treat the LNs also in the order as specified in IEC61850-7-4, but SGCB example given in section 13.1 (figure 17) of IEC61850-7-2 is totally different in the arrangement of data & LNs. Also Figure-3 of IEC61850-7-2 shows a relationship between dataset and SGCB, which is not defined anywhere else in the document.
Proposal: The setting group data (FC=SG) in SGCB has to be first arranged according to the LN (order specified in 7-4 or alphabetical order ) and then should be arranged as specified in 8-1. The examples given in section 13.1 (figure 17) should be corrected accordingly.This applies to Figure-3 of IEC61850-7-2 also.
