Hi, When all LEDs start cycling it means the CPU went into an unresponsive state. The cause can be a many things from HW error to corrupted memory content or even EMC/power supply issues. Have a look at this thread:
Anyways if you check the CPU installation then maybe worth considering the CPU firmware upgrade as well. See this thread about these advices S7-400H Fault . I hope I could help! |
