Nothing specific but i was using the UDS Admin utility and was wondering whether there was a way of using the UDC connector to get to talk with a UDS that i might develop.
Individual UDC's are basically COM objects that implement a specific set of interface(s) for accessing metadata and data. The UDS framework deals with the actual request handling, formatting, caching, aliasing, and other functions.
There are really three options for custom "connectors", depending on the type of data and any technical limitations.
Option #1: Write an OPC or OPC HDA "server" for the target system and use our OPC or OPC HDA UDS to access it. This is best for a typical "tag-based" data source (historian, PLC/DCS, etc.).
Option #2: Write a custom UDS.
Option #3: Write a custom action block for the xMII business logic service engine (BLS is extensible).
That really helped. Could you please explain the options in detail or maybe point to resources on the net which might help me in exploring these options.
