In a nutshell, IoT in manufacturing provides these functions.

  • Data Collection: Captures raw data from a network of smart sensors and machines, which would otherwise be inaccessible.
  • Data Aggregation: Gathers data from diverse sources, including heterogeneous machines, sensors, legacy systems/hardware, modern systems, and other relevant devices, and send data to a centralized platform via IoT gateways.
  • Data Enrichment: Analyzes and adds contextual information to the collected data.
  • Data Visualization: Presents data in easily understandable formats.
  • Actionable Insights: Converts data into actionable insights, enabling managers to implement effective optimization strategies.

Additionally, edge computing can automate certain tasks, reducing the need for human intervention and further optimizing production processes.

IoT in Manufacturing Examples

Predictive Maintenance

Traditionally, manufacturers would replace equipment parts at set intervals to mitigate the risk of failure and prevent production delays. This require dedicated maintenance personnel to regularly check equipment status and once there is a fault, the technicians need to plan maintenance and the production may be interrupted.

However, IoT technology now allows for real-time monitoring of machine conditions, ensuring maintenance is performed only when necessary. This approach not only lead to cost and time savings, but also enables technicians to schedule maintenance ahead of time to minimize production interruptions.

For example, Artesis, a company specializing in paper and pulp production equipment, adopted a predictive maintenance system using industrial IoT sensors. This implementation led to a 20% reduction in maintenance costs and a 10% increase in production efficiency.

Energy Management

IoT analytics offer valuable insights into energy consumption at the equipment and plant levels, helping to pinpoint areas where energy is wasted. This enables managers to seal the wastage loopholes, such as by reducing standby loads or preventing peak loads, to lower energy costs and environmental impacts.

Ford is a prime example of effective IoT energy management. The company installed IoT smart lights in its plants that adjust their brightness based on natural lighting conditions, resulting in annual energy savings of $4 million. Similarly, Armal, a portable toilet manufacturer, achieved nearly a 40% reduction in energy costs by implementing real-time IoT energy monitoring of their production lines.

DTU

Data Transmission Units are critical in the smart manufacturing environment because they transmit RS232 and RS485 data wirelessly from remote devices to a central monitoring system or industrial gateways.

The device typically uses techniques like GPRS, GSM, 3G, 4G, or 5G to send the data, which eliminates the need to wire the industrial protocol communication across long distances. DTUs can also provide control operations via RTUs (Remote Terminal Units).

Sensors

Sensors collect the actual data from the machines, equipment, and environment. Since this data is in analog form, the stack needs an RTU to convert the analog variables into digital data for serial transmission via RS232 or RS485.

So the arrangement starts with sensors connected to RTUs, then to DTUs and out to the gateway. But the DTU might not be necessary if you don’t need wireless transmission.

Gateway or Routers

Industrial gateways and routers collect and aggregate the data to transmit it to the cloud. DSGW-380 industrial 5G gateway with edge computing and light AI processing capabilities are becoming increasingly popular because they can automate tasks and provide analytics functions near the data source.

Servers (Local or Remote)

Servers provide the heavyweight analytics function to help in making informed decisions. Remote servers eliminate hefty installation costs and include platforms like AWS and Azure. On the other hand, local servers provide better data security because all communication remains within the LAN. Platforms like SCADA provide both remote and on-premise servers, so you can use the most suitable option.

IoT Technologies Used for IoT Manufacturing

5G

The 5th generation mobile network, or 5G, offers significantly faster upload and download speeds, increased bandwidth, and more reliable connections. This technology supports real-time, round-trip communication between DTUs, gateways, and remote servers, especially when wired connections are not available.

AIoT

AIoT represents the integration of Artificial Intelligence (AI) with IoT. This synergy allows edge devices to learn, adapt, and make autonomous decisions while performing light analytics on data from industrial sensors. This capability enhances the efficiency and intelligence of IoT manufacturing operations.
