WINCCOA (3.12) <-> C # data read / write

[SMT_SOL]

I am using WINCCOA version 3.12.
DataPoint used in real time in WINCCOA
I am trying to read and write in a C # program. How do I do it?
(Is there a way to access it directly from C # besides the API Manager?)

In WinCC OA 3.12 you cannot use C# in API manager. Using C# in the WinCC OA API or a CTRL extension is possible since WinCC OA 3.15.
You can probably use one the standard interfaces which WinCC OA supports to read data with an external program, e.g. via HTTP or XML RPC.

Thank you for your kind reply.
Where can I find manuals using XML RPC or HTTP?

[leoknipp]

Information for the CTRL functions httpServer() and the XML RPC (search for XML RPC) in the WinCC OA Documentation.
The documentation is part of the WinCC OA installation.
