PLC and HMI Development with Siemens TIA Portal
By :

In TIA Portal, both PLCs and HMIs can be run in soft simulate mode. When this occurs, the hardware runtime is run from TIA Portal, instead of the hardware. This runtime then behaves in the same way it would as if it were running in the hardware.
To start a PLC simulation, select the device that's required from the Project tree area and click the Start Simulation button via the toolbar at the top of TIA Portal:

Clicking the Start Simulation button will automatically switch the network connection interface to PLCSIM.
Note
When you're running the PLCSIM interface, it is not possible to connect to another physical device, even with a different instance of TIA Portal (or even SIMATIC Manager, if it is installed).
TIA Portal automatically disables the ability to simulate new blocks in a new project. If you...
