I need an urgent help please.

I have the following Profinet setup:

- One CP343-1 is connected to four ET200M IM153-4 through Scalance XB008 switch.

When I make the hardware configuration and download it to the cpu (CPU314), the CP 343-1 and the IM 153-4 are giving red led blinking SF and BF LEDs. 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".

I tried also to call the instructions FC11/FC12 but I got the same error.

Thanks in advance.

Hello,

red LED means there is no connection between the devices.

Check the names of the devices and IP adresses, both must matches the data from HWConfig exactly!

Have you crate a topology connection? If yes remove it in the Step7 project.
