Key Takeaways
- Start with machine monitoring on a few critical machines.
- Live OEE and downtime alerts deliver quick, visible gains.
- Energy monitoring often pays back faster than expected.
Industry 4.0 can sound expensive, but most factories begin with a simple goal: know which machines are running, idle or stopped, and why. IoT sensors and PLC integration make that possible even for older machines.
Building blocks
| Component | Role |
|---|---|
| Sensors and PLC connectors | Capture run status, counts and readings |
| Edge gateway | Collect and send data securely |
| Cloud or on-premise platform | Store and process data |
| Dashboards and alerts | Live OEE, downtime and energy |
| Integrations | Link to MES, ERP and maintenance |
High-value use cases
- Live machine status and part counts
- Downtime alerts to supervisors
- Energy consumption per machine and shift
- Temperature, pressure and vibration monitoring
- Automatic production data for MES
Retrofitting older machines with simple sensors is usually possible without changing the machine controls.

Frequently Asked Questions
What is Industry 4.0?
The use of connected machines, data and automation to make manufacturing smarter and more efficient.
Can old machines be connected?
Yes, with retrofit sensors and gateways in most cases.
What is OEE?
Overall Equipment Effectiveness, measuring availability, performance and quality.
Cloud or on-premise?
Both work; cloud is quicker to start, on-premise suits strict IT policies.
