The Dualistic Nature of Devices

Question

This is a Gas UPDM issue.  We have a great number of CP test points connected to valves, and this has stumped me.  I can create a new terminal configuration, but there are times when a device acts as a device, and times when it merely acts as a junction, depending on the subnet tier.  I invite Esri and the Gas Utility Community to analyze this situation.

Yes, I verified that I can have a pipe and test lead wire connected to the same terminal of a controlling device.

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.

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.
