Metasys network engines can network together for scaling up on large projects. When the number of Network Engines becomes larger than a single network engine can efficiently handle as the Site Director, you can add a Metasys Server as the Site Director to unify the system.
The Metasys Server connects to the network engines over the Ethernet IP network and coordinates access to the system for all users. You can use a VPN over a WAN for communication to devices in other buildings or on remote sites; access remote sites over the Internet and an ISP, or by leased line or dial-up service using Remote Access Service (RAS) or the Point-to-Point Protocol (PPP).
