I have studied the Allen Bradley literature and searched through the forums and I am getting conflicting information. On one hand, it would appear that the Panelview Component line of screens (specifically a C400 in my case) are not capable of ethernet communications with compactlogix/controllogix PLCs (have to use serial). On the other hand allen bradley states in the panelview manual that a 2711P- CBL-EX04 (ethernet crossover cable) should be used for a direct runtime connection between compactlogix controllers and component series HMIs. So what gives?
I've tried every configuration I can think of to get a C400 panelview talking with a compactlogix controller. I already have the data mapped out into N7 and F8 arrays, I just can't get the things talking. I could run them both into a swtich, and hook up to either one of them on my laptop, but they won't communicate to each other. Obviously, ip addresses and subnet masks are good. I feel like I am either missing something very obvious, or that this task is actually impossible. Any advice? Thanks.
