Hello Abdo; The LEDs are simply saying that you should open the diagnostic buffer and look at what the CPU is complaining about. The LEDs indicate that you have an internal fault (fault inthe CPU, such as a programming error or a watchdog timer overrun), an external fault (diagnostic fault on a module or in the rack) and a remote module (Profibus) error. But for details you should open the diagnostic buffer. If you need help decyphering the cointents of the diagnostic buffer copy the relevant entries here, we wiil try to help. For details on the diagnostic LEDs, have a look at the S7-400 CPU Specifications manual: http://support.automation.siemens.com/WW/view/en/14016796 Hope this helps, Daniel Chartier |
