Hi everyone,
I have never done DLR networks before and would love to get some feedback on some of the design methodologies that the hardware engineers in my office are playing with.
We have two isolated subsystems with 37 devices each. These sub-systems have their own PLC (1756-L72) on a 10 Rack chassis. The devices communicate to the PLC via an 1756-EN2TR card in their respective DLR networks (All devices are DLR capable). We need to find a way for these 2 PLCs on seperate subsystems to communicate with each other (for produced/consumed tag purposes).
Is it possible to add a 2nd EN2TR card on their respective PLC racks and connect them in a second ring network? In other words, is it possible to have two parallel ring networks?
Thanks!!
