Hello IAHMSA; In the following discussion there were a few very interesting posts describing your problem, with possible solutions.
flashing all LEDs on the CPU
https://support.industry.siemens.com/tf/ww/en/posts/27801/ Basically, all LEDs flashing means that the CPU is signalling a DEFECTIVE state. Here is how the Programming with Step 7 v5.5 manual suggest you react to a Defective state:
Defective, in other words, a fault has occurred.
To check whether the CPU is really defective, switch the CPU to STOP and turn the power switch off and then on again. If the CPU starts up, display the diagnostic buffer to analyze the problem. If the CPU does not start up it must be replaced.
Hope this helps, Daniel Chartier |
