Different network engine models are available, each with different field device capacities, so you can select the model that best meets the size, complexity, and scope of your specific project.
For projects that exceed the capacity of a single engine, Metasys network engines may be networked together, and they may be networked with a Metasys Server for additional functionality and site unification. Also, a network engine, connected to a small number of other network engines, can act as a Metasys Site Director without the need for a Metasys Server.
