Is there a way to find the type of interface associated to a point-source via AF-SDK?
If you need to do this in code, would suggest you use the PIPointSources and PIPointSource classes in the AFSDK. I haven't been able to test this due to some access issues with my development PI server, but I believe the following code snippet should get you started:
PIServers _piServers = new PIServers();
PIServer _piServer = _piServers["mypiserver"];
foreach (var ptSource in _piServer.PointSources)
Alternatively, the Pointsources table in PI-SMT can tell you the information you are looking for.
Thanks john. This code will provide the description if it has been configured in the ICU.
I was looking for the interface name or type like OPC/PItoPI/OPC-DA/UFL etc.
As I mentioned, I haven't been able to test that code (which I usually do before posting any code examples) - I wasn't 100% sure if the description would include the associated interface type. The only other likely property is the Name property, but I think that is the actual point source itself ("C", "OPC", "#", etc) rather than the name of the associated interface.
As far as I know, the actual interface name/type associated to a point source is only stored in the PI Module Database by the PI-ICU for interfaces that have been configured with that application. If this is the case, you would need to implement PI-SDK code to access and traverse the Module Database.
I don't think you can get what you are after using the AFSDK, and using the PI-SDK to read the PI-MDB is a little bit ugly but may be your only option for programmatic access to this information.
