Hello batur; Let's start with a description of the functionnality of a CP 443-1:
As you can see, this communication processor allows the CPU to connect to Ethernet (Siemens' Industrial Ethernet protocol is supported, and Profinet, web services...over TCP/IP connections). No MPI or Profibus on this module. What you are trying to do, in Siemens speak, is called "routing", that is reaching the CPU over the backplane through a CP. The CP can be Ethernet, as in your case, but then the interface between your programming device (PC with Step 7) and that particular CP must be through Ethernet. So you beed to connect your Ethernet NIC on the PC with the CP, both connected to the same switch, for example, make sure both the CP and the NIC have domain-comnpatible addresses (they must belong to the same sub-network), and then use Step 7's Accessible Nodes interface to try anbd see the CPU from the PC. That means that the CP must have an existing TCP address before you use it to connect to the PC. You must therefore provide a complete hardware copnfiguration, including the CP's address, through MPI the first time you connect to the CPU. Only thn will the routing functions be available. The following FAQ will give you a bit more informatiopn on routing: http://support.automation.siemens.com/WW/view/en/584459 Hope this helps, Daniel Chartier |

Dear Batur, is it what you intend to do? Do you want to do PG Functions with STEP7 to download a HW Config with a lower baudrate on the MPI Bus? Best regards J_Bell |
