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.

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.

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.
QuickDesk ATU industrial data collection and deployment guide
QuickDesk ATU is an industrial 4G data acquisition gateway with an embedded MCP service. It reads Modbus RTU instruments over serial connections and reports data over MQTT. AI Agents configure polling parameters and variables through MCP. ATU supplies data for energy management, equipment monitoring and MES applications.
Where does ATU fit?
Meter reading and energy monitoring
Read voltage, current, power and cumulative energy variables defined in a Modbus RTU meter manual, then report them to a customer platform over MQTT. Check the register map, data types and serial settings first.
Equipment data for MES
Collect Modbus RTU instrument and equipment data for production monitoring and dashboards. ATU handles collection and reporting. The customer or integrator supplies MES interfaces, business logic and an environment for AI-generated applications.
Multiple projects and overseas sites
Reuse MCP configuration workflows across projects and configure a separate MQTT Broker for each factory. Remote access requires connectivity through a trusted network. Engineers should review polling points and reported results.
