これはGas UPDMの問題です。多くのCPテストポイントがバルブに接続されており、これには困っています。新しい端末構成を作成することはできますが、サブネット階層によって、デバイスがデバイスとして機能する時もあれば、単にジャンクションとして機能する時もあります。EsriおよびGas Utility Communityの皆様にこの状況の分析をお願いしたいと思います。<\/P><\/BODY><\/HTML>
Mark,
Can you explain the problem some more? Are you looking to connect the Test Point to the valve via a Test Lead Wire? I just looked we are missing that rule from the model, but makes sense to allow it. That valve will need a value of Traceable in the Cathodic Protection Traceability field so it is not a barrier to the CP network. This can be set via the material or the override field. The test lead wire has a category of CP Only, which is a barrier to the gas network, so the test point is not included in the gas system.
If I create a rule for test lead wire to valve, there must be a reference to terminals. Those terminals are occupied elsewhere.
It just occurred to me that it may be possible for more than one line feature to be assigned to a valve terminal. If that's the case, then there may not be a problem after all. I'll look into that possibility after my latest round of experiments, which take considerable time.
Well here I go thinking myself around a catnip mouse again. Even if I can attach a test lead wire to a controllable valve in a pipe network, what happens if the valve is closed to gas? It should still be able to trace for conductivity. That's where the "cptraceability" field comes in, I guess. I need to do some more playing around with this.
Great Question. You can close the valve and the CP network does not care. The DeviceStatus Network Attribute is not used in the subnetwork definition for CP.
Yes, I verified that I can have a pipe and test lead wire connected to the same terminal of a controlling device.
