Ignoring the error message, I think I was able to compile and load CFC in T400, but in Test Mode I receive #### value for input signals of T400. Ragrds Teoh

You can check if your connection working in the following way: Open CFC-chart, go to the menu 'CPU-Module Information', if you get the result window with the CPU state, then your connection is ok. Also you can go to the menu 'CPU-Compare', if you get the window with compare result, then your connection is ok. Could you also try a fresh installation, i.e. new VM, new Win XP and new Siemens SW install?
