I have a few questions about a DeviceNet setup that I am going to be possibly building sometime soon.
Ok, everything in our plant is Allen Bradley, so I'm sticking with that. The setup is simple...I'll have either a 1769-L32E or 1768-L42 Compact Logix controller. Throught the DeviceNet I will be controlling 10 PowerFlex 4 VFD's. I have done a ton of reading on AB's website, but I thought I would ask the gurus to see what their input was. My question is, what do I need to make this work?
Besides the VFDs and PLC themselves...I know I need a "1769-SDN" module to go in the PLC (right?), I belive I need a "22-COMM-D" module for each VFD. Of course I need the physical DeviceNet wiring...I see round, KwikLink, and KwikLink Lite on AB's website. Has anyone tried these and what is your opinion on the best way to wire this?
Would it be better to use PowerFlex 40's that are already ready for DeviceNet, or to go with the 4's and 22-COMM-Ds like I said earlier? And any suggestions on anything else I'm forgetting?
