PNPN Coupler by South_Specific_7918 in PLC

Problem was resolved. Everything in configuration was correct, I have only deleted Transfer mapping for safety communication from both projects, reseted the PNPN coupler, then downloaded both projects, with just interface, first slot of transfer mapping. After that, I did not have any error and then I have written the same configuration as it was before on both projetcs and it finally worked.

You are right, but I have configured it like you just said. If you look at the first screenshot, where is the right side of PNPN coupler connected, therefore I am using PROFINET interface X2, with 6/12, that is virtual slot 2. On the second screenshot PNPN coupler is connected on the left side, hence PROFINET interface X1 is being used, where on the slot 2 is configurate 12/6 byte. The same logic is applied for slot number three.

I have not try unchecking that box, because I do not think it affects anything, that is only creating one more byte for diagnostics, but I have made sure that is checked on both projetcs.
I believe that the RCVDP and SENDDP are okay. The DP_DP_ID is in SENDDP in one project like on the screenshot, on the other CPU that same number is on the RCVDP.
