Requirements and Installation

• Correct installed WinCC OA version 3.7 or higher

• The WinCC OA CtrlXmlRpc is a CONTROL extension including XmlRpc functions. Therefore, you have to load the CONTROL extension in your code by using #uses "CtrlXmlRpc"

  or load it in the config.level file (see chapter To load Control library).

• In order to run an XmlRpc server, you have to start the HTTP server and install a handler. The default URL for XmlRpc is "/RPC2". See also httpConnect().

A regular installation of WinCC OA version 3.7 or higher is sufficient for the use of the WinCC OA XML-RPC.
