NiagaraAX multi-site network application

In the example presented in Figure 6, ABC Company has added a JACE to a LAN at another site. The sites connect to each other using a private data line that is leased from a phone company, thereby creating an enterprise-wide WAN.

Niagara proxy points are used to update the “live” graphic (Px) page presentations on the AXSupervisor. However, the network site administrator decided to move the AXSupervisor onto the enterprise LAN at the primary site, since there is more data traffic generated internally than the occasional external BUI use. The internal IP address of the AXSupervisor changed to one in the IP range of the new network to which it is attached, but the external address (because of NAT) did not change.
