I/O & Connectivity

Connect industrial sensors and plant data sources

The M4 gateway brings wired and wireless condition-monitoring data into one edge system for dashboards, history, and enterprise handoff.

Modbus RTU/TCP over RS-485 and Ethernet
Analog 4-20 mA loop and 0-10 V sensor inputs
Private LoRaWAN with built-in LNS and application server
Wireless full-spectrum vibration and electrical-signature sensing via FSK

Visualization

Build dashboards directly from a browser

Operators can create dashboard pages without code, place live gauges on uploaded layouts, and combine graphs and KPIs from sensor or data sources.

Drag-and-drop dashboard pages
Live gauges on uploaded machine or facility layouts
Graphs and KPIs from sensor and data-source values
Browser access for on-premises and remote users

Historian & Data Access

Keep high-resolution history on the device

The embedded historian stores sensor and Modbus time-series data locally while exposing direct interfaces for automation, analytics, and reporting.

High-resolution time-series database for sensor and Modbus data
Local storage on the gateway internal memory
Direct queries through OPC UA, MQTT, and GraphQL API
CSV and Google Sheets export paths

Manageability

Configure and maintain deployments without code

The gateway is designed for scalable field setup with browser-based configuration, OTA support, and fast device enablement through the I/O plugin.

OTA updates for current device support
Fast I/O plugin for rapid device enablement
Zero-code web UI for gateway configuration
Multi-sensor setup in minutes for repeatable rollouts
