Hi IO_Rack, thank you for the answering reply, appreciate it !  We'll surely look at the mentioned NAT device.  Just out of curiosity, will a standard off the shelf router do the job as well?

Dear All,I'd like to ask whether it is possible to connect 2 PLCs (both have EtherNet/IP capability) through a router.Here is the case :- We have 3 machines each with Compact Logix AB PLC.- We need to retrieve data from each Compact Logix AB PLC, to an Omron NX PLC via EtherNet/IP Protocol- The problem is, currently each of the Compact Logix PLC has same IP addresses, since they are OEM machines installed with no integration in mind before. - The OEM & customer, doesn't allow us to change the IP address of the PLC.- The solution we could think of is to do NAT with router, the thing is we are not really sure whether EtherNet/IP could be translated by NAT.Thank you
