Manufacturers rely on their equipment to keep production running smoothly, but many factories are still operating with machinery that predates modern digital technologies. Replacing all legacy equipment with smart machines isn’t always practical or cost-effective.
However, with the Internet of Things (IoT), manufacturers can connect legacy equipment to modern smart systems, gaining real-time data insights without the need for a full hardware overhaul.
Bridging the Old with the New
IoT integration is transforming the manufacturing floor, making it possible to collect, analyze, and act on data from older equipment. Whether you’re dealing with a 20-year-old CNC machine or an analog press, IoT device integration allows you to modernize without sacrificing the reliability of your existing infrastructure.
The Challenge of Legacy System Integration
Legacy equipment wasn’t designed for digital connectivity. Unlike modern industrial machines that come equipped with built-in IoT sensors, older machines often lack the ability to communicate with newer systems. This presents a few key challenges:
- No built-in sensors – Many older machines don’t have sensors to collect operational data.
- Proprietary systems – Legacy machines often run on outdated or proprietary software, making integration tricky.
- Limited connectivity – Older equipment may not support modern network protocols like Wi-Fi, Ethernet, or MQTT.
- High replacement costs – Replacing legacy machines with new smart equipment is expensive and can disrupt operations.
Despite these challenges, IoT makes it possible to bring legacy machines into a connected infrastructure without replacing them outright.
How IoT Integration Works with Legacy Equipment
Manufacturers can retrofit older machines with IoT-enabled devices to connect them to smart systems. This is typically done using industrial IoT sensors, edge devices, and cloud-based analytics.
1. Adding IoT Sensors
IoT sensors can be attached to legacy machines to monitor temperature, vibration, pressure, and other key metrics. These sensors gather data in real-time and transmit it to IoT gateways or edge computing devices.
- Vibration sensors detect signs of mechanical wear.
- Temperature sensors help monitor overheating.
- Energy consumption sensors track machine efficiency.
- Flow meters ensure hydraulic and pneumatic systems function correctly.
2. Using IoT Gateways for Communication
Because legacy equipment lacks modern communication protocols, IoT gateways act as a bridge. These devices collect data from sensors and convert it into formats compatible with modern networks, enabling seamless connectivity with ERP, MES, and cloud-based IoT platforms.
- IoT gateways support multiple protocols (Modbus, OPC UA, MQTT, etc.), allowing them to integrate with both old and new systems.
- Edge computing can process data locally before sending it to the cloud, reducing latency and bandwidth usage.
3. Cloud and Edge Computing for Data Analysis
Once legacy equipment is connected, the data it generates can be processed, stored, and analyzed using cloud-based IoT platforms like Prophecy IoT®. These platforms provide real-time monitoring, predictive analytics, and automated alerts to help manufacturers optimize production efficiency.
- Predictive maintenance – IoT data helps identify signs of potential machine failure before it happens.
- Operational efficiency tracking – Manufacturers can monitor machine uptime, cycle times, and bottlenecks.
- Remote access – Supervisors can check machine status and performance metrics from anywhere.
The Benefits of IoT Device Integration for Legacy Equipment
Connecting legacy equipment to IoT-powered systems delivers significant advantages for manufacturers, without requiring a full equipment replacement.
1. Extended Equipment Lifespan
With real-time monitoring and predictive maintenance, manufacturers can reduce wear and tear on legacy machines, extending their operational lifespan. Early detection of mechanical issues helps prevent costly breakdowns and unplanned downtime.
2. Increased Operational Visibility
IoT integration provides full visibility into equipment performance, helping manufacturers optimize production scheduling, reduce waste, and improve output. Data-driven insights enable better decision-making at every level.
3. Cost Savings vs. Full Equipment Replacement
Replacing legacy machines with new smart equipment can be a multi-million-dollar investment. Instead, retrofitting old machines with IoT sensors and gateways provides many of the same benefits at a fraction of the cost.
4. Improved Energy Efficiency
IoT-enabled monitoring allows manufacturers to track energy consumption across machines. Identifying inefficient equipment can lead to optimized power usage, lower utility costs, and sustainability improvements.
5. Compliance and Quality Control
With IoT integration, manufacturers can track real-time compliance data, ensuring that machines operate within regulatory and quality control guidelines. Automated alerts can notify operators of deviations, helping maintain consistent production standards.
Real-World Use Cases of IoT Integration in Manufacturing
Automotive Industry
A Tier 1 automotive supplier with aging hydraulic presses integrated IoT sensors to monitor pressure and vibration levels. With real-time alerts, they reduced unexpected breakdowns by 35% and improved production uptime.
Aerospace Manufacturing
An aerospace manufacturer connected legacy CNC machines to an IoT-driven analytics platform, enabling real-time performance tracking and preventive maintenance scheduling. This reduced rework and scrap rates by 20%.
Food & Beverage Processing
A food processing plant added IoT-enabled temperature sensors to existing refrigeration units. By integrating data with an ERP system, they improved energy efficiency and maintained FDA compliance for cold chain storage.
Steps to Get Started with IoT Legacy System Integration
1. Assess Existing Equipment – Identify which machines need IoT integration and what data is most critical to monitor.
2. Select the Right IoT Sensors – Choose sensors that capture the required data, such as vibration, temperature, pressure, or power consumption.
3. Implement IoT Gateways – Use edge devices to convert machine data into a format compatible with smart systems.
4. Integrate with ERP and MES Systems – Ensure data flows smoothly from legacy machines to enterprise-wide smart systems like Infor SyteLine ERP.
5. Leverage Cloud Analytics – Use an IoT analytics platform like Prophecy IoT® to process and visualize machine data.
