What's the simulated PLC?

Are you using nettoplcsim?

Yes, you should to use it, because PLCSIM don't listen on a network card, it don't open the TCP port 102 (or any other). The communication between the Tia Portal/Step 7 with PLCSIM is done via software (propably COM or DCOM) via PC/PG Interface.

Because of this, you should use nettoplcsim. It is a "gateway" between this software communication and the TCP port 102 (necessary to comunicate over ethernet).

It's a small and very simple to use. Take a look: http://nettoplcsim.sourceforge.net/

The best regards,
