サブネットワークと無電化機器の更新

EdwardBlair

こんにちは -

ユーティリティネットワークのシナリオは次のとおりです：フューズを開いて、フィーダー ABC123 の単相タップを保護します。編集を検証して保存し、編集を停止して ABC123 のサブネットワークを更新します。フューズを開いて無電化にしたフィーチャは、現在どのフィーダーにも属していないにもかかわらず、依然としてサブネットワーク名が ABC123 のままです。

ここで何か見落としていることはありますか？または、無電化フィーチャに「Unknown」のサブネットワークを割り当てるために必要な他の手順は何でしょうか。

情報をいただけると幸いです。

Thank you very much.. we will have to dig into eventing and see if it will help us. Your feedback has been really helpful.

DamienPyne

I had to go digging to confirm. Yes we have eventing off. This was not an option with UNM v3 which is where we started. Its one of those options and enhancements we did not go to when we uplifted to v6.

Hi @DamienPyne -

It seems like enabling "eventing" might enable the responsiveness to device status changes we now see with ArcFM Feeder Manager (in 10.x) . But it also seems there are pros and cons to this. Have you purposefully avoided enabling "eventing"?

Thx,

EdwardBlair

Well... that's what we would want. Mike Miller stated that what we see is expected behavior *in a version with eventing off*. Is it possible that you are performing the update subnetwork in SDE.Default? Or that you have eventing enabled?

Thanks for the reply!

EdwardBlair

Mike -

Thanks for the explanation.

As you mentioned, in our experience (so far) the subnetwork trace returns expected results. Unfortunately this is also, at least initially, another source of confusion. I've got a trace telling me one thing and subnetwork name values telling me another.

This is as expected in a version with eventing off. This is caused by how Branch versioning works. In a version, a row only exist if it was modify. So take Eds example

1: Create Version - At this point, there are zero records with that branch ID

2: Open Fuse - This edit adds a new record to the device table with the updated attributes. The Branch ID of that row references this active version

3: Save/Validate/Update Subnetwork- Since there is only one row with this versions branch ID, this is the only record that can be updated. If Update Subnetwork were to update the affected down stream features, those edits would show up in default.

Hopefully this helps. Running a subnetwork trace will display the correct results.

@EdwardBlair - I am noticing the opposite of what you have suggested.
I have opened up a fuse. After the subnetwork update -
The fuse has the SUBNETWORKNAME field populated but all assets downstream of it have the SUBNETWORKNAME blanked out.

After "closing" the fuse and updating the subnetwork you can see the subnetwork name restored. (Ignore the "::" that an unrelated issue )

I guess its similar to a load shift. You have subnetwork 1 and subnetwork 2. To update the changes of the shift where SN1 is now part of the old SN1, you need to update both SN1 and SN2. If you only update SN2, then there is a section not yet updated.

Same theory here. You have a section of network not part of that update (ie your deenergised features), and the IsConnected will clear the SN value and flag these as isconnected = False. Ie they are isolated network objects.

EdwardBlair

This is "as expected"? Really?? Pretty confusing. I'll try the IsConnected.

Thanks much Damien for the reply.

DamienPyne

We have seen this, and raised to Esri. We had been advised this is "as expected". Our workflow advises the user to use the subnetwork line to review for the update.

You should see these features IsConnected value updated, and when you run IsConnected the subnetwork should then update to unknown.

Hi Lynn -

I *am* running Update Subnetwork in a version. I'll give the post and update in Default a try. Thanks for the suggestion!

LynnMoeEsri

Hi Ed - I wonder if you are running Update Subnetwork in a version. If so, try posting your version and running Update Subnetwork in default and see if 'Unknown' is then listed in the subnetwork name field.
