Hi everyone,

I am facing issues with the CPU50M0 card. In one of the ports, the Profibus loop getting lost.

Having this status during fault condition:

Error Class 4098

Error Code 774

Green LED: Flashes quickly (every 0.2s)

Yello LED: Dark

There is no description of the above error code & class.

Please help me to find out the root cause of the frequent failure of the Profibus loop.

I have swapped the card, the problem remains the same.
