Overview

These certified-partner Linux gateways provide 2–4 GB RAM and 16 GB storage in a palm-sized enclosure. Native drivers cover Siemens S7, Mitsubishi MC, Modbus RTU/TCP, and PROFINET; MQTT(S) and HTTP(S) carry normalized data northbound. Gigabit Ethernet, dual-band Wi-Fi, BLE 5.0, optional 4G, and digital I/O leave enough room for filtering, buffering, and local rules at the machine.

Deployment scenarios

Where this class earns its place.

For the digitization lead

Retrofit without touching the PLC program

The gateway reads S7 or Mitsubishi traffic without altering validated control code.

For the CFO

A gateway cost that works across the fleet

Locally engineered gateways lower the per-machine cost when a rollout grows from a pilot to a 200-machine estate.

For the solution architect

Keep the field layer portable

The gateway is not tied to one cloud provider, so an infrastructure change does not require replacing field hardware.

Works with InfiIoT

The protocol, variable mapping, and platform handshake have already been tested.
