Profinet communication failure in hardware configuration

[beemboss]

Hello All,

I need urgent help please if you do not mind. I have a project that contains the following :

- one CPU S7-314
- one CP 343-1
- Four ET200M IM 153-4

The CP 343-1 and the four IM 153-4 are connected to Scalance switch XB008 to generate a profinet communication. When I make the hardware configuration and download it to the cpu, the CP 343-1 and the IM 153-4 are giving BF and SF red led blinking and the CP 343-1 diagnostics buffer giving the following error:

Event ID: 16#F9C1:0220

"I/O enable by S7 CPU, External error, Incoming event"


Thanks in advance.
