Split Controlnetwork between connectivity servers
I've got a 800xA System 5.1 AS , CS and AC800M Controllers.
The AC800M controllers are connected to a WAN Network (VPN)
at the end the configuration will have up to 80 AC800M controllers.
We have split the Connectivity servers to handle the AC800M Controllers.
My question is do i have to split the connectivity network?

As far as I know, you can connect a maximum of 12 AC800M controllers to a connectivity server (single or redundant), for the control network you can have a maximum of 100 nodes if you use PM89x controllers, the number decreases to 60 if you use PM85x or PM86x controllers in your network. I would say that if you have different processes, you could think in separate control networks in that way you are preventing network loops that could end in a broadcast storm and a blocking of your controllers.
See System documentation -> Network configuration -> section 1 for further information. Hope this helps
