Short Proposal:

1. TapOpR and TapOpL are for control by GOOSE 2. TapChg/TapPos.valWTr has the transient indication. TapChg/TapPos.valWTr will be updated with transient indication even if the command has been executed with control by GOOSE or by any other means. RTE will provide more information from the use case with the people originating the issue.

Standard(s):

IEC 61850-7-4

Description

1.The semantic of TapOpL et TapOpR (ATCC) is not clear between status and control objects. In IEC61850-7-3, it is mentionned "The command is received ('opRcvd') by the IED as a control service or as a GOOSE message with a data object semantic resulting in a change of the controllable object (e.g. CSWI.OpOpn/OpCls, CPOW.OpOpn/OpCls, PTRC.Tr, RREC.OpCls, RBRF.OpEx, ATCC.TapOpR/TapOpL, SIMG.InsTr, ...)." or ATCC.TapOpR/TapOpL are status DO (SPS).

2. There is no DO in YLTC to indicate that the position is being changed.

1. Risk of misunderstanding.
2. Helpful for maintenance and exploitation of the system.
