Description

61850-6 ed2.1 mention in I.4.2.4 "New CDC":

"The CDC ORS has been added to the list of the allowed CDCs. DOType whose CDC=ORS shall be excluded from the export to an 2007B environment. This includes also DO instances using this type."

But other CDCs were also added (cf tPredefinedCDCEnum, or 7-3): CST, VSD and TCS
Why shouldn't they be excluded also ?

Proposal descriptions

CST, VSD and TCS should also be excluded.
Action: Reformulate downgrading rule 2.1 to 2.0 for new CDCs to list the supported CDCs instead of the CDCs to remove.
The document will be updated with IEC 61850-6 Amendment 2.2
