SIMATIC WinCC Open Architecture Forum

Sometimes, after installation of the PG/PC interface, it is possible that some network devices are not visible in the "Access Path" tab of the Set PG/PC interface.

You can solve this issue if you follow the instruction from the following link - chapter "Make device drivers selectable and visible"

Note:
In Windows 7 64-bit or later the device drivers are not in the Registry but are available as an XML file in the following directory:
"C:\\ProgramData\\Siemens\\Automation\\Simatic OAM\\data\\LogDevices"

There is also the possibility that the directory "C:\\ProgramData\\Siemens\\Automation\\Simatic OAM\\data\\LogDevices" does not exist or is empty. If the Directory is empty please rename it or delete the empty Directory.
To solve this issue start the PG/PC interface from the MS Windows ControlPanel as an administrator.
For that please go to the MS Windows ControlPanel press on the PG/PC interface icon the SHIFT-Key and press also the right mouse bottom and execute than this program as admin.
The PG/PC interface list build up from scratch. Best regards Franz
