Hello 5678; There are many reasons that can provoque the blinking of diagnostic LEDs on a S7-400H system, see for example the following discussion: https://support.industry.siemens.com/tf/ww/en/posts/114271/ The best way to answer this kind of question if to ask you to open the diagnostic buffer of the PLC, as suggested. Follow the link.proposed by member Georgio to read up on accessing the diagnostic biuffer. The diagnostic buffer contains logs of all events that affect the CPU, so it should be able to tell you what the PLC is complaining abpout (and what lights up the diagnostic LEDs). If you have trouble understanding the messages of the diagnostic buffer, use the SAVE AS.. button in the diagnostic buffer windo to save it to a text file that you can attach here. We may be able to help you understand the source of your problem. Hope this helps, Daniel Chartier |
