If BF is still lit, BF means this: Interface networked but no LAN cable inserted or Duplicate IP address detected ==> another device on the network has already the IP assigned to the CP. If you are sure that this does not apply, In the screenshot you can see a button "special diagnostic". If you click on it, NCM will be opened and you will may be get more info.

When using port 502 you mayrun intoundefined state. If you need port 502 for ModbusTCP communication, I recommend this Simatic AddOn: ModbusTCP Regards, Kaulquappe

The CP can act as Profinet IO Controller/device. I suspect that the Profinet name of the CP is already in use on the network. The device name must be unique on the Ethernet subnet. Look in HWconfig. For CPs with configurable ports, there are some parameters in the properties dialogs of the PROFINET interface. Another way could be to ugrade the CP to V2.3. This can be done online. Look here: (http://support.automation.siemens.com/WW/view/en/42123315) for the changes. You will see that there is the following change: If no PN IO functionality is used, no check is made for duplicate device names. Therefore, no error LED is activated.
