When a switch is needed for the particular topology, the switch should support the DLR function. If not, the connection 
might fail. Since AS Series PLC CPU does NOT support DLR function, you will need a DLR switch DVS-103I02C-DLR 
for a ring topology.   
 
 
9.2.2.3 EIP Builder Software 
Linear and star topology 
Firstly install the EIP editing software on your PC to monitor and configure the EIP devices and use a switch to connect 
to the EIP Scanner and EIP Adapter.   
 
If there is a duo port on the EIP Adapter, you can also take this advantage to start a Daisy-chain topology.
