Industrial Applications

1. S7-400 plant network gateway

Use as the Ethernet communications layer between an S7-400 controller and plant-wide PROFINET/Industrial Ethernet infrastructure, where dual-speed interfaces and routing are required.

Problem Solved

Connects legacy S7-400 automation to modern Ethernet networks without adding separate gateway hardware.

2. Multi-segment machine line integration

Ideal for production lines that need one gigabit uplink and multiple 100 Mbps switch ports to segment HMIs, drives, and diagnostics traffic on the same controller module.

Problem Solved

Reduces network congestion and simplifies cabinet wiring by integrating switching into the communication processor.
