General question regarding the L3xER/ERM/ERMS CompactLogix Controllers and the two EtherNet ports.
Is it possible to configure the two ports on different IPs and subnets? Guess what I'm trying to do is a similar setup to a ControlLogix with two ENBT modules, so one for the local net and one for plant net and data exchange with higher level systems.
I might be confusing the two ports as being separate NIC interfaces, but in reality it might just be two ports on a hub internal to the CPU for purposes only of setting up DLR. If this it true, it would seem that I would need a "managed or smart" switch (start topology and in my case a Stratix 5700) and do port forwarding to a static IP on the plant net.
Can someone confirm, deny my thoughts or suggest an alternative solution?
