Hello,

I have a problem with my PG/PC interface. I cannot choose my own physical network card as PG/PC Interface. With PN/IE it only shows 'PLCSIM' and if I put on my wireless, that card comes available too, but i Have to use my network card with cable to connect to several OP's / PLC's...

When i enable the 'Local Area Connection' with a correct IP-adress I can ping within 'CMD' to the several OP's / PLC's, yet it does not show up in TIA Portal as PG/PC interface.

I have Windows 7, 64-bit.

Is this an installation fault? Or can i change this anyway?

Hello,

yes this looks like a installation fault.

you should try ti recreate the Interface data for your System.

If this not work tthen delete the data in the path
"ProgramData/siemens/automation/Simatic OAM" and run the s7epaimp64x in a CMD shell with adminstrator privilieges (run as Admin).
