Hi, I have a control logix system with a pair of redundant CPUs, that are to communicate with remote I/O using Controlnet. I have attached a simple layout of the described system. However, in the documents I've seen for Controlnet and reducnacy systems say that at least 2 nodes in addition to the CNBs or the redundant pair is needed. Is this topology not correct? The system as it is hooked up now, is not communicating with the Controlnet modules and I/Os and I wanted to see if this was the reason. I'm not very experienced with Allen Bradley/Rockwell products. Can someone point me in the right direction?
