Just Published: CDV IEC 62351-7 -- Network and System Management (NSM) Data Object Models

IEC TC 57 has just published the first CDV of
IEC 62351-7 comprising 208 pages:
Power systems management and associated information exchange - Data and communications security - Part 7: Network and system management (NSM) data object models
The ballot closes 2016-06-17
This draft STANDARD will (when released) supersede the Technical Specification "IEC TS 62351-7:2010".

The NSM objects will provide monitoring data for TC57 protocols used for power systems
(IEC 61850, IEC 60870-5-104) and device specific environmental and security status. Also
IEEE 1815 DNP3 is included in the list of monitored protocols. The NSM data objects use the
naming conventions developed for IEC 61850, expanded to address NSM issues. For sake of
generality these data objects, and the data types of which they are comprised, are defined as
abstract models of data objects.
In order to allow the integration of the monitoring of power system devices within the NSM
environment in this standard a mapping of objects towards the SNMP protocol is provided.

110 pages contain the SNMP MIB Mapping.
Excerpt of some objects related to MMS:

Please take some time to comment.
The document should be available online for comments by end of this week or so.
