Hello Mokhtar; There are various documents available on the forum that show the LED flashing patterns that appear when proceeding to an overall reset of the S7-400 CPUs, using the mode selector switch. One is the Automation System S7-400 Hardware and Installation manual, you can download it here: https://support.industry.siemens.com/cs/ww/en/view/1117849 Hope this helps, Daniel Chartier |
