Product advantages.
A direct path from industrial registers to usable machine data.
Modbus RTU acquisition
Poll standard registers without modifying PLC logic or interrupting the machine's existing control flow.
Built-in MCP interface
Give AI agents a structured way to read manuals, map registers and prepare validated acquisition settings.
4G and MQTT delivery
Send live machine data to your own broker and platform, even when wired network access is unavailable.
Connect. Acquire. Monitor.
ATU AI configurator
Tell ATU what data you need.
Describe your signals in plain language. AI turns them into a validated, read-only Modbus collection plan.

Collect, configure, deliver.
ATU acquires sensor and equipment data over RS485, processes it at the edge, and delivers a clean continuous stream to your platform over 4G / MQTT.
Practical ways to put ATU to work.
From one machine to a distributed fleet, turn existing Modbus data into useful operations without rewriting the PLC.

Process equipment
See machine health before a stop becomes downtime.
Collect pressure, temperature, running hours and alarm registers from pumps, compressors or production equipment. Stream the readings to your own platform for dashboards, maintenance rules and exception alerts.

Connect, then publish
Bring the site online, then send data to the right platform.
Set DHCP or a fixed IP, gateway and DNS first. ATU then switches to MQTT configuration for the broker, client identity, reporting interval, topics and Modbus variable mapping—one continuous commissioning workflow.

For machines already in service, ATU can also be added through a read-only RS485 connection.
