Hi!  
I need to access an Allen-Bradley PLC (CLX) that is behind another PLC. The usual communication path in RSLogix 5000 would be something like:  
10.0.0.10\Backplane\2\A\172.16.0.10\Backplane\0  
In this case, we go from the communication card with 10.0.0.10 to backplane, to communication card on slot 2, to 172.16.0.10 to the backplane and CPU un slot 0.  
Any way to do this with node-red-contrib-cip-ethernet-ip?  
Thanks!  
Francois

So, it is called routing.  
Looks like the PCCC node has it for the older PLC's.
