Why do you not get a connection between PLCSIM and a Panel Simulation after migrating to WinCC TIA V14?

  • Entry
  • Associated product(s)
No connection can be established between PLCSIM and Panel Simulation after project migration from V13 to V14. You get the message "140001: Connection disconnected:".
It is currently not possible to connect a panel with firmware version V13.0.1.0 or lower with PLCSIM V14. When you start PLCSIM/Panel Simulation there is no communication.
You get the error message "140001: Connection disconnected:".

If you change the firmware version to V14.0.0.0, communication can be established again.


  • Open the device view of the panel concerned.

The firmware has now been changed to V14.0.0.0. This means that communication between PLCSIM and a Panel Simulation can be re-established.
