Hello Linoel;

It is obvious you have a fault in your CPU, possibly with the hardware or the configuration.

Use the diagnostic buffer to find out what messages are logged there, you might have hints from the CPU on what it is complaining about (provoking the activation of the diagnostic LEDs).

The screenshot below is taken from the following manual, which I suggest you keep near you when you are working with a S7-1200 CPU.
