CI 801 no profibus connection
Hello,
I have a CI801 module with I/O. I cannot reach the CI 801.
The P led is green steady
The T led is flashing yellow
I tried another profibus cable with the same effect.
I hope someone can help me. Thank you.

What is the error you get?
In General, check
1) Firmware is upgraded?
2) Address Set on Station & CBM are equal?
3) Profibus terminations are proper?
