Hello Mouadeiano; Is this a general interest question, or are you looking at a very real situation? The answer depends on the type of failure you are facing: - no active LEDs (including 5V LED) on the CPU means no power; - all LEDs flashing on CPU: memory failure; - SF LED active and communication with CPU not possible: MMC defective or missing; - ... Provide us with more information and we can give more precise answers. And the diagnostic buffer of the CPU will show messages related to different types if failure of your system, if you are still able to communicate with your CPU. You should also look into the troubleshooting section of the Programming with Step 7 manual for more information: https://support.industry.siemens.com/cs/ww/en/view/45531107 Hope this helps, Daniel Chartier |
