On your PC with PLCSIM, you need to select your ethernet adapter in the PG/PC configuration, instead of PLCSIM interface.

With the PLCSIM interface, PLCSIM can only communicate with TIA Portal.  
This method is also usefull to established a communication between a real HMI and PLCSIM.

Instead you can use, if you have the license, PLCSIM Advanced which allow to select PLCSIM interface or Ethernet TCP/IP interface on the top of the window.
