The idea of segmentation is closely related to addressing. For best practice in Metasys , assign static IP addresses to the ADX, network engines, and switches. These addresses are obtained from the IT address space. For best practice, assign each controller a dynamic IP address from an address space that is private with respect to IT. The use of private addresses allows Johnson Controls to install a large building automation and control network while consuming only a small amount of IT-assigned IP addresses.

If you extend a VLAN into the IE switches from the IT switch, you need a trunk port connection, as shown in Figure 1. Alternatively, if traffic is routed to and from the building’s network, you can implement a routed port instead.
