With a Layer 3 industrial switch, engineers can subdivide the network into several subnets. These switches make it easy to integrate existing machines, systems, and subnets into higher-level networks, improving network stability and security. A NAT enabled switch can easily integrate systems with the same IP address range into a higher network. Layer 3 switches are ideal for more advanced applications with multiple network segments. The device has routing and NAT functions as well as common managed switch functions.
