• Conventional production machines

View our IoT gateway devices to see how we connect to different machine types.

M-Connect collects machine signals directly from equipment using a dedicated IoT gateway installed on each machine. These signals are transmitted to our monitoring platform where they are analyzed to provide real-time operational insights. See how this works in practice in our IoT implementation examples.

No. The gateway reads the machine’s electrical signals from outside the controller, so no CNC program and no machine hardware is changed. How retrofit installation works.

The system captures key operational signals including:

• Machine run status
• Cycle start and cycle completion
• Idle states
• Alarms
• Production counters

These signals help generate accurate production analytics.

Many Industry 4.0 projects fail because they focus only on technology and not on real shop-floor problems. M-Connect focuses on capturing real machine data and providing practical insights that help improve production performance.

Real-time machine data helps management understand machine performance, production output, and operational losses. This information allows factory leaders to make faster and better decisions for improving productivity.

Because monitoring usually shows the existing machines have unused capacity — and utilisation recovered is output gained without capex. Measure before you buy.

We use our proprietary retrofit device, M-Connect, to acquire data directly from machines. M-Connect operates independently of the machine's make, model, or type, ensuring seamless integration across diverse industrial equipment. This allows us to collect real-time operational data without relying on existing PLCs or protocols like OPC UA or MTConnect, making it a highly adaptable and scalable solution for any manufacturing setup.

We primarily focus on collecting high-level business-critical data from machines. The key data points include:

• Running Time
• Idle Time
• Cycle Time
• Energy Consumption
• Machine Interlocks
• Operator Details
• Alarm Logs

While we do not capture low-level parameters like spindle speed or vibration, our software platform applies intelligent analytics on the collected data to provide actionable insights—such as cycle time anomaly alerts, productivity deviations, and downtime patterns.

The retrofit device works independently of make, model and controller — on older machines it reads electrical signals, control panels or external sensors directly. Connecting mixed and legacy controllers.

Wi-Fi, 4G or Ethernet, and very little bandwidth — typically 128–256 Kbps per device, because the gateway processes at the edge. Network requirements in full.
