IM151-3 modules not detected

Hello,

I am working with a S7 1214C CPU (6ES7214-1AG40-0XB0) along with a Profinet IO ET200S (IM 151-3 PN ST 6ES7151-3AA23-0AB0) with several IO modules attached (6ES7138-4CA01-0AA0 as the power module and 5 6ES7131-4BF00-0AA0 8xDI and 2 6ES7132-4BF00-0AA0). I'm also using the terminating module 6ES7193-4JA00-0AA0.

The problem I'm having is that while the CPU and its modules work perfectly, I can't get it to recognize the ET200S. I've correctly configured the hardware in TIA Portal V16 ant the ET200S is correctly wired because it lights up and so do the modules with active inputs (each LED corresponding to an input).

Going online to the CPU shows the error message "Error in a lower level component" and while it can access the interface module of the ET200S, it says the other modules (PM and digital IO) are not present. These are correctly conected to the rack and the rack is correctly assembled.

The only indication in the hardware are the SF and BF lights on the Interface Module that blink red, first 3 or 4 times at 0,5Hz and then at 2Hz the same amount of times, and finally just the BF blinks once. The SF led on the PM also lights up continuously. The manual doesn't have a clear diagnostic or resolution for this issue so I hope someone can help.

Thank you.

hello,

Could you send us the diagnostic buffer in txt format?

Thanks you
