What it sits as in the panel
The Mitsubishi NZ2EHG-T8 is an 8-port gigabit Ethernet switch built for CC-Link IE field industrial networks, delivering 1 Gbps throughput across distributed automation cells. It sits in the PLC accessory layer — not as a controller but as the managed backplane that ties CC-Link IE nodes together at line speed.
Why the gigabit rating carries the BOM line
The 1 Gbps throughput is the headline that decides fit on a CC-Link IE cell — anything slower becomes the bottleneck on a multi-node ring carrying motion, vision, and I/O traffic on the same segment. Spec the switch against the CC-Link IE node count and the worst-case scan load, not against the headline port count.
