Proposal of a new LN class ASWI
IEC 61850-7-4 Ed.3
This is to register a user requirement for a new LN class ASWI, independent from ASEQ LN class proposed in IEC/TR 61850-90-14 which is intended to model FACTS and HVDC Automatic Sequencer.
ASWI LN class should model an execution scheme of a series of switchgear controls. Once activated by a DOns control, it will go through a configured list of 1 … n individual switchgear controls (CSWI.Pos), with associated ctlVal for the intended switching directions, and will execute them one after the other. The successful execution of the actual step shall be the precondition for executing the next one.
Option: It should be possible to select the execution sequence (forward/backward) using the common ctlVal of the DOns control. In backward mode the ctlVal for the individual controls should be inverted.
The proposal is to enhance the definiton of ASWI LN allowing multi equipment controlled by CSWI changind the presence condition of OpOpn, OpCls, SelOpn and SelCls data objects.
The work will be address in IEC 61850-7-4 Ed.3 as 90-6 TR LN definition is plan to be moved to this standard.

ASWI has already been defined in IEC TR 61850-90-6. The functions identified here seems to be provided the ASWI in 90-6.
So please refer to it before you start to work on the LN design.
If the ASWI in 90-6 is not proper to implement the functions identified here, please define a logical node whose name is other than ASWI.

- Status changed from Triage to Resolved
- Discuss in Upcoming Meeting changed from Yes to No
- Proposal descriptions updated (diff)
- Standard(s) set to IEC 61850-7-4 Ed.3
90-6 ASWI definition is only for a single equipment controlled by CSWI. It could be enhanced to admit at least one, but more than one, as it was done with GAPC in 90-11. In the context of 90-6 it could be restricted to only once.
In edition 3 there is a plan to move 90-6 TR LN definitions to IEC 61850-7-4, so this modification could be addressed then.
