User data failure of hardware component

Hello,

I have a module that is connected through profinet with a S7-1200 PLC.
Sometimes the PLC goes into different errors, mostly in this order :

- user data failure of hardware component
- IO device failure - watchdog time expired
- IO device failure - IO device not found

Mostly the error go away by them self, but it has happened that I had to restart the PLC also to get it to work again.

Under user data failure of hardware component I see : 

What could cause these problems.

I already replaced the cable with a shielded version and that seemed to help alot, since I only had to restart the PLC once since then.

Hello,

could you send us the diagnostic buffer?

Thansk you

New question published by Sundance00 is split to a separate thread with the subject S7-1200 with ET200: User data failure of hardware component.
