CPU318-2 All Lights Flashing

Sad to say, but usually that means, that CPU is dead. Only practice advise i can give - take good blower to blow out dust from modules and U-backplane joint pieces. Also check if all pins on backplane are ok.

Also can try to launch only CPU (without modules).

If you get lucky it would work)) But still it's DEFECTIVE state, so generally it had to be replaced.

Hello kkoos,

what happend befor?
Did you load a new programm or something like that?

Maybe you load a newer firmwareversion of your CPU?
Which Version are you using?
Here you could find the newest one I think: Operating system updates for S7 318-2 CPUs

Good luck
