There is a device level ring in our plc network. It means we connect to one plc from other plc. Is this library support such a connection ?

This library allows reading and writing tags on AllenBradley Control Logix or Compact Logix PLCs via the Ethernet/IP protocol. It reads or writes tags on a PLC controller addressed via the IP address of that PLC. If that PLC exchanges data with other PLCs over the DLR and makes that available in tags, that's great, but there's nothing in here that would directly go from the IP of one PLC through the ring to tags on other PLCs.
