Windows 7 Runtime: Installation and configuration
Requirement:
- On the host PC: Editor: TwinCAT 2.10 Build 1326 or higher

The installation consists of three steps:
1: Installation of the Internet Information Server IIS

- See http://http://technet.microsoft.com/de-de/library/cc725762%28v=ws.10%29.aspx
- Make sure that the ISAPI filter and extensions are also installed (see picture)
2: Installation of the supplement software on the host PC
- The supplement software is installed on your PC with the Win 7 runtime by entering the required licence key and agreeing to the licensing conditions
3: Configuration of the Internet Information Server (IIS)
- Create a “virtual directory” with the name “UPnPDevice” with a link to the directory “.\Programs\Beckhoff \UPnP\WebSite”
- Create a “virtual directory” with the name “TcWebVisu” with a link to the directory “.\TwinCAT\Boot\WebVisu”
- Add the following DLLs under “IIS/ISAPI and CGI Restrictions” and permit their execution:
- C:\Program Files\Beckhoff\UPnP\WebSite\TcPlcDataServiceDa.dll
- C:\Program Files\Beckhoff\UPnP\WebSite\TcPlcDataService.dll
- Permit the action “Execute” under “Handler Mappings”
