Author: Andreas Vogler Homepage: www.rocworks.at Communication from .Net client to WinCC Open Architecture. GPLv3 License is used for the public domain. If you plan to use it in a CLOSED SOURCE project, please get in touch with me - andres.vogler@gmail.com ! Communication can be done directly with XMLRPC or with the included proxy: * .net remoting is used for "commands" from the client to the proxy (dpConnect, dpQueryConnect). * tcp (xml over tcp) for sending unsolicited data/events from the proxy to the client. The proxy also acts as a distributor - if clients have the same dp(Query)Connects, the connects in the control are done once, and the proxy will forward it to the clients. Added functions for dpConnects without using "Tag" Objects (the Tag objects where created for mobile clients). Now it is easy to create for example a dpQueryConnect. The callback function is just a C# delegate: // create server and client objects client = new WCCOAClient (ProxyHost, ProxyRemotePort, ProxyClientPort); // start and connect client.Start (); client.Connect (); Thread.Sleep (1000); // wait until client id is registered client.DpQueryConnectSingle((object s, ArrayList a) => { WCCOABase.PrintArrayList(a); Statistics(); }, "SELECT '_online.._value', '_online.._stime' FROM '*.**'"); The proxy (WCCOANetServer.exe) must be started on a server (can, but must not be, the WCCOA Server). Basic communication is done via XMLRPC https://sourceforge.net/projects/roc-xmlrpc/ Works fine with MonoTouch and Mono for Android. http://www.rocworks.at (not sure if the added .Net remoting also will work) WinCC Open Architecture must run the included Ctrl-Script xmlnet_server.ctl Change List: 2013.01.01: Added Proxy-Server for dp(Query)Connects. 2012.12.23: Added a very simple C# WinForms application which displays two datapoints, waits for value changes and values can also be set by a button out of the WinForms application. 2012.12.23: Added WaitDataMulti function which performs a dpWaitForValue. Can be used to wait for a change of value of data points of a taglist.
