Windows 7 Runtime: Installation and configuration

Requirement:

• On the host PC: Editor: TwinCAT 2.10 Build 1326 or higher

Installation:

TwinCAT PLC HMI Web is available as supplement and can be installed via Setup. A licence is required. A limited demo version is not available.
The installation consists of three steps:

1: Installation of the Internet Information Server IIS

• The Internet Information Server (IIS) is not installed as standard in Windows 7. This function must be subsequently installed
• 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”

• Select “Applications pool identity” under “IIS \Authentication\Anonymous Authentication”.

• Restart the IIS service
• The installation is now completed.
