Edge Thing, OPC-DA
The most common Edge Thing (as opposed to an Edge Enhanced or Edge Database Thing) is an OPC-DA connector. The OPC-DA tags are represented as properties on the server Edge Thing definition.
You must identify the Channel being used to communicate to the remote Edge Thing.
When you configure the .NET Edge Thing components at an OPC-DA server, you configure which tags you want to expose to the ThingWorx server. You then need to bind server properties to the edge data. See Edge Thing Properties for more information.
