Description

In the communication between substations and control centers a mechanism to block the information update for a certain grid segment or bay is widely used today.
The reasoning behind is that the control center should not see false status indications while a bay is in maintenance.

The data model of IEC 61850-7 currently does not provide means to efficiently implement this function.
What currently exists is the DA "blkEna" for all substitutable DOs. This fulfills the requirement of blocking a single DO from getting reported to the control center.
Blocking a whole bay or grid segment would require to set "blkEna" for a bunch of DOs. This is error prone and creates additional testing efforts during FAT / SAT.

Proposal descriptions

The request is to add a mechanism on logical device or logical node level that allows to transmit the the block status from the logical device or logical node to all underlying DOs.
E.g. new "blkEna" DO beeing inherited in LLNO and all LNs. Status then is transmitted in similar ways as for "Mod".
