Error in lower-level component and Wrong partner port

I have purchase 1212C DCC/DC/RLY module with an 6ES7 212-1HE40-0XB0, and after establishing connection and loading first program, it still shows error " Error in lower-level component" and "Error on partner - wrong partner port". Also error led is blinking, which is (for me) annoying. How to clear errors, or just prevent new ones from showing (and how to turn off that led)? I couldn't find anything useful about it around internet, so I hope that somebody here can help. I have tried all that facility and no useful for me. It could be great if somebody help me on this??. Here with the attached file

Please check that your project's topology view matches the actual port connections. Delete the connections in the topology view when working with the S7-1200. Only have the network connections.
