Hello Everyone, I am facing issue on site. I am using CPU 417-5H along with IM153-4(PROFINET) and IM 152 (Profibus). I am having 5 Profibus Node and 13 Profinet Node. Profibus IM are redundant and working Fine. All the module are connected in SRP configuration ( Profinet Network Start from CPU1 and End at CPU2). I used CPU1 port 1 for 1st IM and then looping it to another. Last IM is profinet cable is end at CPU2 Port 1. Also I Have VFD which is Connected CPU1 Port 2 and goes to Scalance XB008 which is unmanaged switch. From Switch i created ring for All VFD ( i.e First VFD is Connected to scalance and then Looping of All VFD , Last VFD is again terminated at Scalance). While system is running for momentry time Profinet communication going in IM153-4 and again come back. and this is happening to all other IM also. Rendomly IM getting loss of communication. Can anyone please tell me what is the reason ??? When i check CPU Diagnostic i am getting below Message in Diagnostic buffer continousely. Also I have attached TXT file of CPU diagnostic Buffer.
