HMI with 2 wire Ethernet
Modern HMI and IP data over existing two-wire infrastructure.
Application Overview
How This Deployment Is Structured
Industrial projects frequently require modern HMI and IP communication but must retain legacy two-wire plant infrastructure. This solution extends Ethernet over existing two-wire lines to connect HMIs, edge controllers and monitoring systems.
It reduces downtime and civil work while enabling digital visibility and remote diagnostics.
Quick Summary
Project Snapshot
| Project Type | industrial |
|---|---|
| Project Need | Factories and utilities need digital HMI upgrades, but trenching and re-cabling production zones can be costly and disruptive to operations. |
| Recommended Approach | Use hardened 2-wire Ethernet transceivers to reuse installed cable paths. Connect HMIs and field devices into segmented industrial Ethernet zones, then backhaul to SCADA or central control.Ethernet over existing two-wire cable pathsIndustrial-grade EMI and surge resilienceRemote HMI monitoring and maintenance accessPhased migration from legacy buses to IP |
