Transform your proven production equipment into intelligent value-creation assets — without expensive new purchases and with measurable ROI.
Your existing production equipment is not the problem — it is your strategic advantage. While competitors invest millions in new machines, targeted IoT integration allows you to reach the smart factory faster and more cost-effectively.
The cost-advantage reality: Retrofit solutions require significantly lower investment than new machinery while delivering much of the functionality of modern equipment. According to Bitkom forecasts, digitalization will generate efficiency gains of €78 billion across six key sectors of the German economy.
You know your machines inside and out. You understand their characteristics, weaknesses, and optimal operating parameters. This expertise makes IoT integration not only technically simpler, but also more economically predictable.
Checklist for evaluation:
• Assess the machine’s criticality for overall production (downtime costs per hour)
• Document age and technical condition (remaining useful life over 5 years?)
• Identify existing protocols and interfaces (fieldbus, industrial Ethernet, proprietary systems)
• Quantify ROI potential from energy monitoring, predictive maintenance, or OEE improvements
When setting priorities, start with machines that cause high downtime costs and already have digital interfaces. This minimizes technical risk while maximizing economic benefits.
Your machine operators and technicians are the key to success. Those who have worked with the equipment for years often identify anomalies earlier than any sensor.
Stakeholder mapping process:
Resistance usually arises from unclear communication of goals and benefits. Emphasize this message: IoT does not eliminate jobs — it makes them more interesting and valuable.
Criterion | Best-of-Breed Solutions | Integrated IoT Platform |
Connectivity | Immediate support for specific protocols | Universal gateway architecture |
Implementation time | 2–4 weeks per machine type | 6–12 weeks initially, then scalable |
Cost per sensor | Higher unit costs | Economies of scale for larger projects |
Long-term flexibility | Limited to selected technologies | Vendor-agnostic data aggregation |
Recommendation: Start with best-of-breed solutions for critical pilot machines. Switch to platform approaches once you plan to connect more than 10–15 machines.
Pilot (Months 1–3): Implement IoT sensors on 2–3 critical machines without downtime. Use external sensors for temperature, vibration, and energy consumption. Validate data quality and identify initial optimization potential.
Scale (Months 4–9): Expand to a complete production line with 10–20 connected machines. Integrate legacy protocols using universal gateways. Develop automated alerts and dashboards for production managers.
Transform (Months 10–18): Implement factory-wide connectivity with a scalable IoT platform as the foundation. Consolidate data from different machine manufacturers. Develop predictive maintenance algorithms and optimize overall equipment effectiveness.
Typical cost ranges per connected machine (market benchmarks):
• Hardware (sensors, gateway): 800–2,500€
• Software licensing: 50–200€ per month
• IIntegration and configuration: 1,500–5,000€
• Ongoing operation and support: 30–100€ per month
These figures are based on market observations and may vary depending on vendors and project scope.
Energy consumption optimization: Monitoring idle times and load profiles enables documented energy savings of 17–26.7% in industry. With annual electricity costs of €200,000, this equals €34,000–53,000 in direct savings.
Maintenance optimization: Predictive maintenance delivers savings of 8–12% compared to preventive maintenance and 30–40% compared to reactive maintenance. Unplanned downtime is significantly reduced through early fault detection.
OEE improvement: Systematic measurement of availability, performance, and quality reveals hidden losses. Even a 5% OEE improvement can generate annual value of €100,000 for large systems.
Industrial IoT implementations consistently deliver positive results. Documented cases report downtime reductions of 28–50% through predictive maintenance and production increases of 20–25% through optimized equipment utilization.
A typical success story: systematical digitalization of heterogeneous machine landscapes over 12–18 months leads to optimized maintenance scheduling and significant reductions in energy consumption. Companies report 30–40% fewer production interruptions alongside 15–25% lower energy costs.
How do I handle different machine protocols?
Universal gateways translate between common industrial Ethernet and fieldbus standards. Modern solutions support PROFINET, EtherNet/IP, Modbus, and proprietary protocols simultaneously via a unified platform.
What about machines without native connectivity?
Retrofit sensors using LPWAN technologies (LoRaWAN, NB-IoT) enable full data capture even on older equipment. External sensors measure vibration, temperature, and energy consumption without interfering with machine control systems.
Process for sustainable success:
Weeks 1–2: Conduct a structured inventory assessment. Identify 2–3 pilot candidates based on downtime costs and technical feasibility.
Weeks 3–6: Evaluate IoT vendors and define KPIs for the pilot phase. Select technology partners with proven legacy-integration expertise and regional presence.
Weeks 7–10: Install initial sensors on pilot machines and test data flows. Train operators and maintenance technicians to use the new insights effectively.
Weeks 11–12: Analyze collected data and develop a solid scaling plan. Present measurable results to executive management to secure approval for the next rollout phase.
Start your digital transformation today — with proven technology and measurable results.
Typically, €3,000–8,000 per machine for hardware, software, and integration. Unit costs drop significantly when scaling to 20+ machines due to platform effects. ROI is usually achieved within 12–24 months.
External sensors can be installed in 2–4 hours per machine during planned maintenance windows. Gateway configuration and data integration occur alongside normal production. Full integration takes 2–6 weeks depending on complexity.
Modern industrial IoT uses encrypted connections and segregated networks. Implement VPN tunnels, firewalls, and regular security updates. Work only with providers that comply with IEC 62443 standards.
