Hello RamarRam; You do know that you can communicate with and download to your CPUs over Profibus, if you have an adequate Profibus CP in your Programming PC, or if you use a PC adapter USB as shown in the following discussion: https://support.industry.siemens.com/cs/ww/en/view/82478488 The important point is to select the PG/PC interface parameters correctly. The descriptions of the LEDs' significance is available in the S7-400H system manual, in section 5.3: SIMATIC Fault-tolerant systems S7-400H (V6.0) https://support.industry.siemens.com/cs/ww/en/view/82478488 The LED description is very general, and do not give you information on which specific slave system is giving alarms. It would be important for you to connect to each PLC and retrieve the diagnostic buffer messages from each, to find out what the CPUs are complaining about. You can use the Save As button on the diagnostic buffer page to load the messages to a text file that you can more easily read. If you need help to understand the logged messages, zip them and attache them to this discussion. Hope this helps, Daniel Chartier |
