I am a newbie when it comes to Ethernet/IP communication and Allen Bradley PLC setup. I have written a program in PLC to communicate with my device over Ethernet/IP communication. Communication is work fine for 1-2 hours, but later class 3 communication stops.
I captured wireshark log to debug the error. But on wireshark, I see the communication between IP address of PLC and PC port only. There is no device IP captured in wireshark.
My first question is -
Is there any setting in PLC and wiresahrk to capture class 3 packets?
Also, in wireshark, I see error packets "Embedded service error" when I connect two devices in line topology. When checked on Studio5000, Module shows ring fault status.
I am not sure why it took as ring topology, while my device is connected in line topology. I am not able to change it from ring to any other topology.
Can someone guide me here, how can I remove this ring fault? and what does this "Embedded service error" means?
Thanks in advance!!!
