I'm able to communicate with Step7 V5.3 with my cable. It's an RS232-MPI adapter. The problem is that I can't find the adapter in the online access of the TIA Portal. I attach a image capture of my online access. Thanks in advance. Attachment Imagen1.jpg (1035 Downloads)

Reference: 6ES7 972-0CA23-0XA0 As I said before, I'm able to communicate with the same hardware through Step7 V5.3. I'm trying with the TIA Portal V11 and I can't. I can communicate with S7-1200 through the ethernet adapter, but I don't know where to find the MPI adapter in the software. Maybe it's imposible and you need an USB adaptor. Thanks.

Hi , If you have PC adapter then you change the port configuration of PLC as profibus then start the accessible nodes on network definetly it will give you resut. here i attach some screenshot for your reference Attachment comm1.JPG (1263 Downloads)

JanvS Posts: 3 Rating: (0)	I have the same problem. There is no way to enable the serial port PC adapter. I cannot produce the screen from picture COMM1.JPG. Can you please be a bit more specific in your explanation on how to configure this? I would be interested to see the settings under the tab 'Local Connection' on the picture 'ALL.JPG' but that one is not showing. In my case I have to set the 'Connection To': combo box option to COM1 to accommodate the MPI cable adapter. Thanks, Jan
