Hello,

I am trying to connect my hmi simulation to a plc 1215 dc/dc/dc. Before I can write values to the plc from the hmi, but now I can't. I've tried to solution using the pg/pc. I using Realtek PCIe GbE Family Controller. 

Closed cause question posted twice.

The second thread with the subject can not communicate the plc with the HMI simulation is published within the conference SIMATIC WinCC (TIA Portal).
