Hello. I had this situation:

I made WinCC project and I integrate in with Step 7 one. I was not very big project of S300 CPU 315. I have plc and I use my PC screen to test my visualization . When it was ready I decided to test it on the real machine. There were S300 CPU 316, so I uploaded the hardware configuration and change my project CPU 315 with CPU 316 and some SM. OK! But then I try to run WinCC project I have “No valid S7 connection”. So I changed the Flex setting and everything was right, but all my tags become orange and I couldn’t start visualization again. So my question is - When I change S7 project (hardware configuration) how to make integrate WinCC project adapt this change and work with new CPU (all tag, symbols, connections and program are the same) ?
