Why do we need Tia Portal PLCSIM? If we don’t have any PLC devices (you maybe know that PLC module at least 100-150 USD so It’s not that cheap module and additionaly if you want to buy for extra modules it can cost a lot.) so Siemens offer to users to have Virtual Simulator.
As you see i downloaded all the parts of Tia Portal PLCSIM V14.

Click the Simatic_S7_PLCSIM_V14 and follow the steps “next,next”.
