scope:

This part of IEC 61850, which is a Technical Report, describes scheduling for devices using IEC 61850.

The parameters, which identify this new namespace, are:

• Namespace Version: 2017

• Namespace Revision: A

• UML model file which reflects this namespace edition: wg10uml02v17-wg18uml02v11bwg17uml02v18- jwg25uml02v04c.eap, UML model version WG17UML02v18

• Namespace release date: 2017-06-12

• Namespace name: "(Tr)IEC61850-90-10:2017A"

The namespace "(Tr)IEC61850-90-10:2017A" is considered as "transitional" since the models are expected to be included in the next editions of IEC 61850-7-4xx and IEC 61850-7-3. Potential extensions/modifications may happen if/when the models are moved to International Standard status. Only the new data objects and CDCs that are not said inherited from existing LNs will be tagged with this namespace name. The others should still refer to the namespace where they are primarily defined.
