Dual Ethernet Replacement (1769-L33ER)

We have a machine that has a 1769-L33ER and we were wanting to connect it to our plant network. Currently has a local network for drives and HMI, was wondering if there is a replacement hat will support 2x networks and retain the same backplane.

I see that we could upgrade to the current generation processors but the backplane is not compatible so we would need to add another 1769-aent and those are not cheap, even on the used market.

Was there a dual network processor available?

All 1769 series are internal switch type only to my knowledge.

You could add a NAT as an option.
